Description

Technology Field

[0001] The present invention relates to a hammer crusher performance analysis device and a performance analysis method capable of analyzing the impact performance of a hammer crusher to suggest optimal shape design according to field operating conditions and methods for improving materials and shape to ensure a long-term lifespan. Background Technology

[0003] The efficient recycling of waste resources is a key task for establishing a sustainable circular economy. In particular, construction waste accounts for a significant proportion of total waste (36.5% as of 2023), making it crucial to effectively crush it and recycle it into high-quality recycled aggregate. The quality and economic value of recycled aggregate are largely determined by the amount of residual mortar remaining on the aggregate surface. Here, residual mortar refers to hardened cement mortar that remains attached to the aggregate surface during the crushing process of existing concrete; a higher content of residual mortar leads to reduced density, increased water absorption, and degraded mechanical performance. Therefore, higher crushing and stripping efficiencies improve the physical properties of recycled aggregate and increase its usability.

[0004] This is directly linked to the advancement of crushing process performance and leads to the need to improve the performance of the hammer crusher, the central device for recycled aggregate production. A hammer crusher is a device that crushes input materials through impact and shearing using hammers at the ends of rotating rotors, and the shape of the hammer directly affects crushing efficiency and energy transfer characteristics.

[0005] For this reason, various studies have been conducted to improve performance by optimizing hammer shape and operating conditions. Representative studies include those that attempted to optimize throughput and energy consumption based on particle behavior inside the crushing chamber and operating conditions using the Discrete Element Method (DEM), and studies have also been reported that analyzed the quantitative relationship between impact force, impulse, specific crushing energy, and damage rate by interpreting the collision and fracture process between the hammer and particles using DEM.

[0006] However, most existing studies have focused on DEM-based analysis targeting specific materials (limestone, grains, etc.) or structural analysis-centered approaches evaluating the stress and vibration characteristics of hammers and rotors, and there have been no reported cases of quantitatively determining the dynamic effects exhibited by changes in hammer shape during actual collision situations through matching with experiments.

FIG. 3 is a side view showing a hammer crusher performance analysis device according to an embodiment of the present invention, and FIG. 4 is a top view showing a hammer crusher performance analysis device according to an embodiment of the present invention. FIG. 5 and FIG. 6 are perspective views showing an input section, and FIG. 7 is a photographic image of a prototype of a hammer crusher performance analysis device according to an embodiment of the present invention.

[0043] Referring to FIGS. 1 to 7, a hammer crusher performance analysis device (100) according to one embodiment of the present invention includes a housing (110), an input unit (120), a shooting unit (130), and an analysis unit (140).

[0044] The housing (110) is formed in a tubular shape extending in the height direction, and a hammer crusher (10), which is the subject of performance analysis, is installed on the inner bottom surface. The hammer crusher (10) includes a rotating body (11) and a plurality of hammers (12) installed at predetermined intervals on the outer surface of the rotating body (11). The rotating body (11) is connected to a shaft (S) that rotates by a rotation motor (M) and rotates.

[0045] The space inside the housing (110) can be divided into an input space (111) into which a target object is inserted, a drop space (112) into which a target object falls, and a strike space (113) into which a target object is struck by a hammer crusher (10).

[0046] When viewed from the side, the input space (111) is formed in a rectangular shape, the drop space (112) is formed in a trapezoidal shape, and the impact space (113) can be formed in a semicircular or circular shape.

[0047] The hammer crusher (10) is installed in a striking space (113), and the striking space (113) can be formed in a semi-cylindrical or cylindrical shape larger than the rotation radius of the hammer crusher (10).

[0048] A transparent window (114) is installed on one side of the lower part of the housing (110). Specifically, the transparent window (114) may be formed on one side of the impact space (113) which is orthogonal to the rotational direction of the hammer crusher (10). The transparent window (114) allows the appearance of an inserted target being struck by the hammer crusher (10) to be captured from the outside.

[0049] The input section (120) is formed in the housing (110) and allows a target object to be inserted into the housing (110) and fall into the hammer crusher (10). The input section (120) is formed on the upper part of the housing (110) and communicates with the input space (111). The input section (120) includes a guide frame (121), a guide (122), and an input port (123). The target object may be a steel ball having a predetermined diameter. Since the present invention is a hammer crusher performance analysis device, a steel ball, which is a solid, rigid body that is not crushed, is inserted for performance comparison analysis under the same conditions. The steel ball inserted through the input port (123) passes through the falling space (112) and the impact space (113) and is struck by the hammer (12) of the hammer crusher (10).

[0050] A guide frame (121) is formed to protrude horizontally from the upper part of the housing (110), and a guide (122) is installed on the guide frame (121) to align and guide the target object. An input port (123) feeds the target object, which is aligned and guided by the guide (122), into the input space (111).

[0051] The guide frame (121) is formed integrally with the housing (110), and the guide (122) is formed to be detachably attached to the guide frame (121).

[0052] Referring to FIGS. 4 and FIGS. 5a, the guide (122) includes a rail member (122a) that accommodates a plurality of striking targets and aligns and guides the plurality of striking targets in a row, a fastening member (122b) that is fastened to the end of the rail member (122a), and a support member (122c) formed on the side of the rail member (122a) to support the rail member (122a) so that it does not shake.

[0053] The rail member (122a) and the support member (122c) may be formed integrally, and the rail member (122a) may be provided in multiple numbers corresponding to the diameter of the target object being struck. Additionally, one side of the support member (122c) may be formed integrally with the rail member (122a), and the other side may be formed in a shape that contacts and is fixed to the inner wall surface of the guide frame (121).

[0054] Additionally, the shape of the support member (122c) may vary depending on the position where the rail member (122a) is installed. For example, as shown in FIG. 6 (a), when the rail member (122a) is installed in a first position, the support member (122c) may be formed with a first surface area to contact the inner wall surface of the guide frame (121). Alternatively, as shown in FIG. 6 (b), when the rail member (122a) is installed in a second position that is repositioned toward the center of the housing (110), the support member (122c) may be formed with a second surface area larger than the first surface area to contact the inner wall surface of the guide frame (121). In this case, although the shape is similar, the width of the support member (122c) changes from W1 to W2.

[0055] If the hammer (12) positioned directly below the first position is damaged by repeated experiments and fails to provide reliable experimental data, the rail member (122a) and the fastening member (122b) are changed from the first position to the second position so that the target object falls from the second position, thereby allowing the experiment to continue without replacing the hammer crusher (10). An opening (115) may be formed at the position where the guide frame (121) is formed on the upper part of the housing (110) so that the rail member (122a) and the fastening member (122b) can be fixed by changing their positions left and right.

[0056] The fastening member (122b) is fastened to the rail member (122a) and placed inside the housing (110). An inlet (123) is formed in the fastening member (122b). The inlet (123) is formed with a size larger than the diameter of the steel ball, but may have a diameter such that only one steel ball can be continuously fed. Multiple fastening members (122b) may be provided according to the diameter of the inlet (123). That is, when the diameter of the steel ball changes, the fastening member (122b) having an inlet (123) with a corresponding diameter and the corresponding rail member (122a) can be fastened together and installed on the guide frame (121).

[0057] Alternatively, as shown in FIG. 5b, a aperture (123b) capable of adjusting the diameter of the input port (123) may be formed in the fastening member (122b). When the diameter of the steel ball changes, the aperture (123b) can be adjusted to form an input port (123) having a corresponding diameter.

[0058] Also, a stopper (123a) may be installed around the input port (123) to prevent a target object supplied and guided by a rail member (122a) from passing through the input port (123).

[0059] The shooting unit (130) is installed on the outside of the housing (110). The shooting unit (130) obtains a striking image by capturing, through a transparent window (114) installed on one side of the lower part of the housing (110), the striking target introduced through the input unit (120) being struck by the hammer crusher (10) in the striking space (113). The type of the shooting unit (130) is not specifically limited, but it is preferable that it be a high-speed camera capable of capturing, for example, 500 frames per second or more. The striking image obtained from the shooting unit (130) can be transmitted to the analysis unit (140) via wired / wireless communication or USB, etc.

[0060] The analysis unit (140) receives a hit image of a target object obtained by the shooting unit (130), and uses the hit image to extract the trajectory of the target object and analyze the performance of the hammer crusher (10).

[0061] The analysis unit (140) performs image processing on multiple impact images to extract the trajectory of the impact target and calculates kinetic energy from the extracted trajectory. The analysis unit (140) can quantitatively compare and analyze the performance of various types of hammer crushers (10) by installing various types of hammer crushers (10) in a housing and then performing repeated experiments under the same conditions to extract the trajectory from the acquired impact images and calculate the kinetic energy. The same conditions mean dropping an impact target of the same size from the same location.

[0063] Next, an example of analysis using a hammer crusher performance analysis device according to one embodiment of the present invention is described.

[0065] 1. Hammer Crusher Performance Analyzer

[0066] First, a hammer crusher performance analysis device as shown in Fig. 7 was prepared. At this time, the experimental hammer crusher to be analyzed for performance is a small hammer crusher designed to be smaller in size compared to a conventional industrial hammer crusher, and is installed on the bottom surface of the housing.

[0067] A Lupa 3000 high-speed camera was used to observe and quantify the dynamic behavior of the input object before and after collision, with the resolution set to 1696×1710 pixels and the shooting speed set to 539fps. Since it takes approximately 0.04286 seconds to complete one rotation using a hammer crusher (1400rpm), shooting at 539fps allows for securing approximately 23 frames per rotation, which is sufficient to capture the moment of impact.

[0068] Velocity data was calculated by extracting the frame-by-frame position of the video captured by a high-speed camera using signal processing techniques and performing numerical differentiation. Additionally, to ensure the reproducibility of the experiment, a separate jig was designed to insert the object, allowing it to free-fall from the same position in every experiment.

[0069] Time-dependent position data of the ball struck by the hammer was captured using a high-speed camera, and the position and velocity were calculated by correlating the position in each captured frame with the actual physical length. The actual position of the struck ball per frame (x i , y i ) are pixel coordinates on the camera frame (X i , Y i ) and the width (W), height (H), and image resolution (W) of the actual filmed space px , H px It was calculated as in Equation (1) using ).

[0071] Equation (1) :

[0073] At this time, image analysis was performed using MATLAB's Image Processing Toolbox. The velocity of the sphere (V xi , V yi ) is the value obtained by dividing the change in position between frames for each axis by the frame time interval (△t), and was calculated through numerical differentiation as in Equation (2).

[0075] Equation (2) :

[0077] Figures 8 to 10 are representative examples of the trajectory and velocity time series of a sphere obtained by post-processing high-speed camera images. Since the direction of motion and impact force can vary depending on minute initial position deviations at the moment the sphere collides with the hammer even when falling from the same height, repeated measurements were performed three times each for sphere diameters of 8 mm and 20 mm to ensure experimental repeatability and increase simulation precision. The position and velocity data derived from individual repeated experiments were subsequently matched one-to-one with the simulation results and used for consistency evaluation.

[0079] 2. Multibody Dynamics Modeling of a Hammer Crusher

[0080] A rigid multi-body dynamics model was constructed using RecurDyn for the simulation. Since the hammer crusher device used in the experiment consisted entirely of steel components, including the hammer, rotor, impact plate, and feeder, the same material properties were applied to the simulation. A rotary joint was installed between the rotor and the base, and motion was applied at the same speed as in the experiment (approximately 1400 rpm). The material properties and contact parameters used were set as shown in [Table 1] and [Table 2]. At this time, all contact pairs (hammer-sphere, sphere-impact plate) were modeled based on Hertzian contact theory.

[0082] [Table 1]

[0083]

[0084] [Table 2]

[0085]

[0087] The normal force is expressed by Equation (3), and the contact constant is calculated from the equivalent radius and equivalent elastic modulus by Equation (4). The equivalent radius and equivalent elastic modulus are calculated by Equation (5).

[0089] Equation (3) :

[0090] Equation (4) :

[0091] Equation (5) :

[0093] In the above equation, E i , v i , R i represents the elastic modulus, Poisson's ratio, and radius of curvature of each contact body, and δ represents the amount of penetration.

[0095] The damping term in the contact force calculation was adjusted through matching with the experiment. Coulomb friction was applied to the tangential direction to satisfy Equation (6).

[0097] Equation (6) :

[0099] In Equation (6), the friction coefficient μ was the generally accepted friction coefficient between steel. After verifying the model consistency through matching with the results of a single collision experiment, this parameter was used identically in simulations comparing dynamic effects due to shape changes.

[0101] 3. Comparison of Simulation Results and Experiment

[0102] To verify the consistency of the constructed simulation model, a simulation was performed under the same analysis conditions as those used in the experiment. Steel balls with diameters of 8 mm and 20 mm were dropped, just as in the experiment, and the position of the hammer immediately before impact and the initial position of the ball were fixed to match the experiment. In addition, the position and velocity data of the ball were extracted by setting the analysis step to the same shooting speed (539 fps) as the high-speed camera. As shown in Fig. 11, it can be confirmed that the simulation accurately implements the behavior after impact when compared to the experiment.

[0103] The post-impact velocity values ​​from experiments conducted three times each on spheres of two sizes (8mm and 20mm) and simulations performed under identical conditions were compared and summarized in [Table 3] and [Table 4]. For the 8mm sphere, the horizontal velocity (V x The average relative error of ) is 0.79%, and vertical velocity (V y The average relative error of ) was found to be 3.49%. When it is a 20mm sphere, the horizontal velocity (V x The average relative error of ) is 2.95%, and the vertical velocity (V y The average relative error of ) was found to be 2.11%.

[0104] These values ​​fall within the range of measurement error that may occur during the experimental image processing; therefore, it can be confirmed that the constructed multi-body dynamics model reproduces the dynamic response of the sphere after impact with high accuracy.

[0106] [Table 3]

[0107]

[0108] [Table 4]

[0109]

[0111] 4. Analysis of crushing performance according to hammer shape

[0112] The simulation results of the multi-body dynamics model showed a trend very similar to the experiment. In this invention, the influence of the hammer's cross-sectional shape on crushing performance was analyzed through dynamic simulation, and the analysis results can be utilized for designing a more efficient hammer shape.

[0113] Figure 12 (a) shows a flat hammer shape, and (b) shows a hammer shape with a V-shaped groove on the top. To analyze the performance of the two hammers, rigid body modeling was performed and simulations were conducted under the same conditions.

[0115] 4-1. Single Ball Hit Simulation

[0116] To analyze the effect of hammer shape changes on the impact performance of a single sphere, flat hammer and V-shaped hammer shapes were modeled. A collision simulation was configured and performed as shown in Fig. 13 by placing the initial position of the sphere to be struck in the groove of the V-shaped groove hammer. Steel spheres with diameters of 8 mm and 20 mm were used as the striking bodies, and the kinetic energy and impact force of the sphere after striking were calculated and shown as in Figs. 14 and 15.

[0117] As a result of the simulation, the V-groove hammer showed superior kinetic energy transfer performance compared to the flat hammer, and the impact force was also 22,417N for a 20mm sphere when using the V-groove, which was about 10.6 times greater than the result of 2,098N for the standard shape hammer.

[0119] 4.2 Mass Ball Hit Simulation

[0120] We performed a simulation considering collisions between raw stones when a large amount of raw stones were input to simulate real-world conditions, examined the total impact force and kinetic energy, and verified the crushing performance by shape in actual situations.

[0121] As shown in Fig. 16, for actual impact situations, 25 spheres with a diameter of 8 mm and 25 spheres with a diameter of 20 mm were arranged in the inlet and randomly placed in a certain area, and a total of 25 analyses were performed. At this time, the sum of the impact forces acting on the impact plate was derived, and the general hammer shape and the V-groove hammer shape are shown in Fig. 17.

[0122] Out of a total of 25 simulation cases, the sum of the impact force of the V-groove was higher in 18 cases, accounting for 72% of the total, and when looking at the total sum of the data, the impact force of the V-groove hammer increased by 49.5% compared to the standard hammer. Therefore, it was confirmed that the V-groove cross-section is more efficient than the straight cross-section.

[0124] According to the hammer crusher performance analysis device of one embodiment of the present invention as described above, the impact performance of the hammer crusher can be analyzed to suggest optimal shape design according to field operating conditions and methods for improving material and shape to ensure a long-term lifespan.

[0126] Although embodiments of the present invention have been described above, those skilled in the art may modify and change the present invention in various ways by adding, changing, deleting, or adding components, etc., without departing from the spirit of the present invention as described in the claims, and such modifications and changes are also to be included within the scope of the rights of the present invention.
