Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing, in particular to a device for measuring the degree of mineral crushing. Background Art

[0002] Ore refers to a collection of minerals from which useful components can be extracted or from which certain properties can be utilized. It can be divided into metallic minerals and non-metallic minerals. During the ore processing process, it needs to be crushed through squeezing and bending to produce smaller particles to meet the needs of the next step of processing. The ore crushing process is the process of reducing the ore particle size.

[0003] However, the particle size of the ore obtained after processing fluctuates within a relatively large range. Particles that are too coarse will have a serious impact on the next step of processing and may cause damage to machinery and equipment. Particles that are too fine will affect the overall quality of the product. Especially in the processing of some bone particle products, too fine a particle size will result in too much powder, and products mixed with a large amount of too fine particles are often used as very low-priced ceramic raw materials, which is a huge waste of resources.

[0004] Accurate ore particle size identification is crucial for predicting and optimizing ore crushing and grinding energy consumption. The crushing performance of the crusher not only affects the capacity of the crushing process, but also the efficiency of downstream grinding operations. Currently, the crushing process in mineral processing cannot measure the degree of ore crushing. Instead, workers rely heavily on their experience to determine the characteristics of the incoming ore. This can easily lead to significant errors. Utility Model Content

Therefore, the components shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the precise shape of the components and are not intended to limit the scope of the present invention.

[0027] Reference Figures 1 to 2As shown, the mineral crushing degree measuring device described in the present invention includes a main cabinet 1, inside which is provided a vertically arranged measuring chamber 2, which is open at the top and bottom and vertically penetrates. Inside the measuring chamber 2, there are provided a plurality of horizontally arranged measuring rods 3, one end of each measuring rod 3 is set on the cavity wall inside the measuring chamber 2, and extends from the opening on the cavity wall inside the measuring chamber 2, extending to the cavity wall on the opposite side of the measuring chamber 2. The extended end is the free end of the measuring rod 3. The measuring rod 3 is internally integrated with a measuring sensor, such as a gravity sensor, a mineral composition detector, etc., for measuring and detecting the mineral particles that fall onto the measuring rod 3.

[0028] The interior of the measurement chamber 2 is vertically divided into N zones from top to bottom, where N ≥ 2. The interior of the measurement chamber 2 is divided into zones 1 through N from top to bottom. Each zone is equipped with a number of measuring rods 3, and the density of the measuring rods 3 in each of the N zones increases from top to bottom. The distribution of measuring rods 3 in each zone is tailored to the target mineral sample and requirements. Preferably, the measuring rods 3 are arranged in multiple rows within each zone, with the measuring rods 3 in adjacent rows staggered relative to each other.

[0029] A horizontally arranged movable sieve plate 4 is provided at the top opening of the measurement chamber 2. Both ends of the movable sieve plate 4 are mounted on the top of the measurement chamber 2. Furthermore, weight measuring modules 5 are provided below both ends of the movable sieve plate 4. The weight measuring modules 5 are located between the measurement chamber 2 and the movable sieve plate 4. The weight measuring modules 5 are connected to a measuring instrument and are used to measure the weight carried on the movable sieve plate 4. Preferably, the movable sieve plate 4 and the measurement chamber 2 are connected in a detachable and movable manner.

[0030] A bottom panel is provided at the bottom of the measurement chamber 2 , and the bottom panel is fixedly connected to the measurement chamber 2 . The bottom opening of the measurement chamber 2 is opened on the bottom panel.

[0031] A base frame 7 is mounted at the bottom of the main cabinet 1, and the two are movably connected. A vibration motor 8 is mounted on the base frame 7 on one side of the main cabinet 1 to vibrate the main cabinet 1. A discharge hole 9 is provided at a position corresponding to the bottom opening of the measurement chamber 2. Mineral material tested within the measurement chamber 2 is discharged through this discharge hole 9.

[0032] A feed hopper 10 is positioned directly above the measurement chamber 2 of the main cabinet 1. A feed opening 11 is located in the middle of the feed hopper 10. Driven by a corresponding drive motor, the feed hopper 10 undergoes horizontal reciprocating or oscillating motion. External mineral material to be inspected is fed into the measurement chamber 2 through the feed opening 11 of the feed hopper 10. Because the feed hopper 10 is in horizontal reciprocating motion, the mineral material entering the measurement chamber 2 is more evenly distributed.

[0033] Behind the measurement chamber 2 in the main cabinet 1 is a chassis 6. Inside this chassis 6, a linear drive mechanism, such as a linear motor, is located for each measuring rod 3. Each linear drive mechanism drives the corresponding measuring rod 3 horizontally, allowing the measuring rod 3 to extend into or retract from the measurement chamber 2. The chassis 7 also houses circuit hardware structures that are electrically connected to each measuring rod 3, enabling the output of detection results from the measurement sensors on the measuring rods 3.

[0034] During implementation, a feed hopper 10 is positioned directly above the measurement chamber 2 of the main cabinet 1. A feed opening 11 is defined in the middle of the feed hopper 10. Driven by a corresponding drive motor, the feed hopper 10 undergoes horizontal reciprocating motion or horizontal shaking. External mineral material to be inspected is fed into the measurement chamber 2 through the feed opening 11 of the feed hopper 10. Because the feed hopper 10 is in horizontal reciprocating motion, the mineral material entering the measurement chamber 2 is more evenly distributed.

[0035] Multiple horizontally arranged measuring rods 3 are located within the measurement chamber 2. One end of each measuring rod 3 is attached to the inner wall of the measurement chamber 2 and extends from an opening in the inner wall of the measurement chamber 2 until it reaches the opposite wall of the measurement chamber 2. The extended end serves as the free end of the measuring rod 3. A linear drive mechanism, such as a linear motor, is located within the housing 6, corresponding to each measuring rod 3. Each linear drive mechanism drives the corresponding measuring rod 3 horizontally, allowing the measuring rod 3 to extend into the space of the measurement chamber 2 and prepare for testing.

[0036] The interior of the measuring chamber 2 is divided into N areas from top to bottom along the vertical direction. A number of measuring rods 3 are provided in each area, and the density of the measuring rods 3 in the N areas becomes denser from top to bottom.

[0037] A horizontally arranged movable sieve plate 4 is provided at the top opening of the measuring chamber 2. Both ends of the movable sieve plate 4 are mounted on the top of the measuring chamber 2. Furthermore, weighing modules 5 are provided below both ends of the movable sieve plate 4. The weighing modules 5 are located between the measuring chamber 2 and the movable sieve plate 4. The weighing modules 5 are connected to a measuring instrument and are used to measure the weight carried on the movable sieve plate 4. When the mineral material falls onto the measuring chamber 2, it will first reach the movable sieve plate 4 at the top of the measuring chamber 2. After preliminary screening by the movable sieve plate 4, the mineral material can be subjected to the first level of inspection and some abnormal or excessive minerals can be removed in advance, thereby protecting the internal structure of the measuring chamber 2.

[0038] As minerals fall within the measurement chamber 2, they are intercepted by measuring rods 3 in N corresponding zones, depending on their particle size. Minerals intercepted by measuring rods 3 remain on the measuring rods 3, with larger minerals ultimately being retained in the upper zones and smaller minerals in the lower zones. Measuring rods 3 are equipped with integrated sensors, such as gravity sensors and mineral composition detectors, to measure and detect the mineral particles that fall onto them.

[0039] A vibration motor 8 is mounted on a chassis 7 on one side of the main cabinet 1, driving the main cabinet 1. As the mineral material falls, the vibration of the main cabinet 1 ensures a more complete and even fall. A discharge hole 9 is provided on the chassis 7, corresponding to the bottom opening of the measurement chamber 2. After being tested within the measurement chamber 2, the mineral material is discharged through this discharge hole 9.

[0040] The back of the measuring chamber 2 in the main cabinet 1 is the chassis chamber 6, in which a circuit hardware structure is provided. The circuit hardware structure is electrically connected to each measuring rod 3 to output the detection results of the measuring sensor on the measuring rod 3.

[0041] After the test is completed, each linear drive mechanism drives the corresponding measuring rod 3 to move horizontally, causing the measuring rod 3 to retreat in the space of the measuring chamber 2. The blocked mineral particles lose their support and fall, thus cleaning the interior of the measuring chamber 2. Then, the next test is ready.

[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
