Abstract
Description
Technical Field
[0001] This application belongs to the field of heavy calcium carbonate production technology, and in particular relates to a heavy calcium carbonate grinding mill. Background Technology
[0002] Heavy calcium carbonate powder is made from high-quality limestone, which is processed into a white powder using a lime grinding mill. Its main component is CaCO3.
[0003] The existing publication number CN217774241 U discloses a heavy calcium carbonate powder grinding mill, including a box body. A feeding hopper is provided on the top of the box body. Two grinding rollers for grinding materials are rotatably connected to the box body, and the grinding rollers are located directly below the feeding hopper. A drive mechanism for the two grinding rollers to rotate in opposite directions is provided on the side wall of the box body. Guide plates located above the grinding rollers are fixedly connected to the opposite side walls inside the box body.
[0004] Although the above-mentioned grinder can quickly drop the material through the screen to the bottom of the box and discharge it through the discharge pipe, some raw materials are not ground sufficiently, resulting in poor grinding effect of heavy calcium carbonate powder. Utility Model Content
[0005] The purpose of this application is to address the aforementioned technical problems by providing a heavy calcium carbonate powder grinding mill that can perform secondary grinding of insufficiently ground materials, thereby improving the grinding effect of the equipment.
[0006] This application provides a heavy calcium carbonate powder grinding mill, including a housing, a feed hopper, a grinding roller, and further comprising:
[0007] A screening component, which is installed inside the housing;
[0008] The discharge port is located on the housing;
[0009] The screening component includes a first screen, a partition plate, and a storage cavity. The first screen is disposed inside the box, and two partition plates are symmetrically arranged inside the box. The partition plates and the side wall of the box form a storage cavity.
[0010] The screening components are installed inside the housing, consisting of a first screen, a partition plate, and a storage chamber. There are two first screens, both inclined and connected to each other. When grinding heavy calcium carbonate powder, limestone is fed into the housing from the feed hopper. An external drive device drives the grinding rollers to grind the limestone. After grinding, heavy calcium carbonate powder with the correct particle size is sieved through the first screen and discharged from the outlet. Larger particles roll down from the inclined first screen into the storage chamber for temporary storage. The operator can then remove the larger particles from the storage chamber for secondary grinding, thus improving the grinding effect of the equipment.
[0011] Furthermore, the box body is provided with a loading and unloading groove, which is connected to the storage cavity, and a pull-out box is installed on the loading and unloading groove.
[0012] Larger particles enter the storage chamber and accumulate in the pull-out box. After the grinding work is completed, the operator can manually pull out the pull-out box horizontally for quick processing of the accumulated material. This design avoids the cumbersome operation of disassembling the box to remove the accumulated material in the storage chamber, which is a traditional method, and significantly improves maintenance efficiency.
[0013] Furthermore, the pull-out box includes:
[0014] Mounting bracket, which is disposed within the loading and unloading slot;
[0015] A rotating shaft, which is mounted on a mounting bracket;
[0016] A storage rack, which is mounted on a rotating shaft;
[0017] The second screen is installed on the storage rack.
[0018] When the user needs to clean and store large particles accumulated inside the pull-out box, they can rotate the storage rack mounted on the rotating shaft. This causes the storage rack to rotate 180° around the axis of rotation, making it easier for the operator to empty the material accumulated on the second screen. After rotation, the user can use a brush to remove the material particles clogging the screen holes of the second screen, completing the emptying and cleaning of the second screen. The user can then push the pull-out box back to its original position to continue storing large particles inside the box. The combination of the rotating shaft and the storage rack makes emptying the material accumulated on the second screen and cleaning the second screen more convenient and efficient.
[0019] Furthermore, a limiting groove is provided on the loading and unloading trough, and a limiting block is connected and installed on the side wall of the storage rack, the limiting block being able to slide along the limiting groove.
[0020] Limiting grooves are opened in the inner wall of the loading and unloading trough, and limiting blocks are welded to the outer walls on both sides of the storage rack. The limiting blocks are placed in the limiting grooves and slide along the limiting grooves to ensure that the pull-out box maintains a straight movement during the pushing or pulling process, and to prevent the storage rack from deviating from the original displacement trajectory due to uneven force.
[0021] Furthermore, a pull ring is installed at the outer end of the storage rack.
[0022] A pull ring is welded to the end of the storage rack away from the rotating shaft. The pull ring has a U-shaped structure, and the operator can easily push and pull the drawer by gripping the pull ring and applying force.
[0023] Furthermore, the pull ring is provided with anti-slip texture.
[0024] The pull ring has a dense anti-slip texture on its surface. This texture increases friction and prevents the operator's hand from slipping. It ensures that the operator can still hold the pull ring stably and apply force even when the powder on the pull ring is sticky or wet, reducing the risk of operational errors.
[0025] The beneficial effects of this application are:
[0026] 1. After grinding, the qualified heavy calcium carbonate powder is sieved through the first screen and discharged from the outlet. The larger heavy calcium carbonate powder rolls down from the inclined first screen into the storage chamber for temporary storage. The operator can then take out the larger particles from the storage chamber for secondary grinding to improve the grinding effect of the equipment.
[0027] 2. After the grinding work is completed, the operator can manually pull out the pull-out box in the horizontal direction to facilitate quick handling of the accumulated material in the pull-out box. This design avoids the tedious operation of disassembling the box to remove the accumulated material in the storage chamber, which is a traditional method, and significantly improves maintenance efficiency.
[0028] 3. After the flipping is completed, the user can use a brush to brush off the material particles blocking the screen holes of the second screen, completing the work of dumping the material accumulated on the second screen and cleaning the second screen. Then, the user can push the pull box to reset so that the pull box can continue to collect large particles in the box. The rotating shaft and the storage rack work together to make it more convenient and efficient for the user to dump the material accumulated on the second screen and clean the second screen.

[0036] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.
[0037] Example 1:
[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown in the figure, this application provides a heavy calcium carbonate powder grinding mill, including a housing 100, a feed hopper 200, a grinding roller 300, and further comprising:
[0039] A screening component 400 is installed inside the housing 100;
[0040] The discharge port 500 is provided on the housing 100;
[0041] The screening component 400 includes a first screen 410, a partition plate 420, and a storage cavity 430. The first screen 410 is disposed inside the housing 100. Two partition plates 420 are symmetrically disposed inside the housing 100. The partition plates 420 and the side wall of the housing 100 form the storage cavity 430.
[0042] The screening component 400 is installed inside the housing 100 and consists of a first screen 410, a partition plate 420, and a storage chamber 430. There are two first screens 410, both of which are inclined and connected to each other inside the housing 100. When it is necessary to grind heavy calcium carbonate powder, limestone is put into the housing 100 from the feed hopper 200. The external drive device drives the grinding roller 300 to grind the limestone. After grinding, the heavy calcium carbonate powder with qualified particle size is screened through the first screen 410 and discharged from the discharge port 500. The heavy calcium carbonate powder with larger particles rolls down from the inclined first screen 410 into the storage chamber 430 for temporary storage. The operator can then take out the larger particles in the storage chamber 430 for secondary grinding to improve the grinding effect of the equipment.
[0043] Example 2:
[0044] like Figure 1 , Figure 4 As shown in the figure, this application provides a heavy calcium carbonate powder grinding mill. In addition to the above-mentioned technical features, the housing 100 is provided with a loading and unloading groove 110, which is connected to the storage chamber 430. A pull-out box 120 is installed on the loading and unloading groove 110.
[0045] Larger particles enter the storage chamber 430 and accumulate in the pull-out box 120. After the grinding work is completed, the operator can manually pull out the pull-out box 120 in the horizontal direction to facilitate quick processing of the accumulated material in the pull-out box 120. This design avoids the cumbersome operation of disassembling the box 100 to remove the accumulated material in the storage chamber 430, which is a traditional method, and significantly improves maintenance efficiency.
[0046] Example 3:
[0047] like Figure 4 As shown, this application embodiment provides a heavy calcium carbonate powder grinding mill, which, in addition to the above-mentioned technical features, includes the pull-out box 120 comprising:
[0048] Mounting bracket 121 is disposed within loading and unloading slot 110;
[0049] A rotating shaft 122 is mounted on a mounting bracket 121.
[0050] Storage rack 123, which is mounted on rotating shaft 122;
[0051] The second screen 124 is installed on the storage rack 123.
[0052] When the user needs to clean and store large particles accumulated inside the pull-out box 120 after pulling it out, the storage rack 123, which is connected to the rotating shaft 122, is rotated to rotate 180° around the axis of the rotating shaft 122. The rotation of the storage rack 123 makes it easier for the operator to pour out the material accumulated on the second screen 124. After the rotation is completed, the user can use a brush to brush off the material particles blocking the screen holes of the second screen 124, thus completing the work of emptying the material accumulated on the second screen 124 and cleaning the second screen 124. Subsequently, the user can push the pull-out box 120 back to its original position so that the pull-out box 120 can continue to store large particles inside the box 100. The cooperation between the rotating shaft 122 and the storage rack 123 makes it more convenient and efficient for the user to empty the material accumulated on the second screen 124 and clean the second screen 124.
[0053] Example 4:
[0054] like Figure 4 As shown, this application provides a heavy calcium carbonate powder grinding mill. In addition to the above-mentioned technical features, the loading and unloading trough 110 has a limiting groove 125, and the storage rack 123 has a limiting block 126 connected and installed on the side wall. The limiting block 126 can slide along the limiting groove 125.
[0055] A limiting groove 125 is provided on the inner wall of the loading and unloading groove 110, and limiting blocks 126 are welded to the outer walls on both sides of the storage rack 123. The limiting blocks 126 are placed in the limiting groove 125 and slide along the limiting groove 125 to ensure that the pull-out box 120 maintains a straight movement during the pushing or pulling process, and to prevent the storage rack 123 from deviating from the original displacement trajectory due to uneven force.
[0056] Example 5:
[0057] like Figure 1 , Figure 2 As shown, this application embodiment provides a heavy calcium carbonate powder grinding mill, which, in addition to the above-mentioned technical features, has a pull ring 127 installed at the outer end of the storage rack 123.
[0058] A pull ring 127 is welded to one end of the storage rack 123 away from the rotating shaft 122. The pull ring 127 has a U-shaped structure. The operator can easily push and pull the pull box 120 by holding the pull ring 127 and applying force.
[0059] Example 6:
[0060] like Figure 1 As shown in the figure, this application embodiment provides a heavy calcium carbonate powder grinding machine, which, in addition to the above-mentioned technical features, has anti-slip texture on the pull ring 127.
[0061] The pull ring 127 has a dense anti-slip texture on its surface. The anti-slip texture can increase friction to prevent the operator's hand from slipping. It can ensure that the operator can still hold and apply force stably even when the powder of pull ring 127 is adhered or wet, reducing the risk of operation error.
