Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and more specifically, to a non-metallic mineral ball milling device. Background Technology

[0002] With the development of the non-metallic mineral industry, the demand for crushing and processing non-metallic minerals is increasing. In the production process of non-metallic mining areas, ball mills are widely used as key equipment in mineral crushing operations. Traditional ball mills achieve the purpose of crushing materials by impacting, squeezing, and rubbing the materials with grinding media (such as steel balls) inside the rotating cylinder.

[0003] However, existing ball milling devices for non-metallic minerals still have many shortcomings in practical applications. On the one hand, traditional ball mills typically require complete grinding before discharge. This operating mode forces the already ground material to continue rotating inside the grinding drum along with the unground material. This not only causes over-grinding of the already ground material, increasing unnecessary energy consumption, but also prolongs the overall grinding time by mixing the unground material with the ground material, significantly reducing production efficiency.

[0004] On the other hand, in the material handling stage, most existing ball mill devices require manual scooping of the crushed material from the hopper. This manual method is not only labor-intensive and inefficient, but also prone to dust pollution during operation, posing a threat to the health of operators. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a non-metallic mineral ball milling device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A non-metallic mineral ball milling device includes a discharge cylinder, a transmission cylinder rotatably mounted inside the discharge cylinder, a ball milling cylinder installed inside the transmission cylinder, filter holes on the surface of the ball milling cylinder, discharge holes on the surface of the transmission cylinder, a transmission mechanism on one side of the outer surface of the transmission cylinder, a loading and unloading mechanism between the ball milling cylinder and the transmission cylinder, support columns fixedly connected to both sides of the bottom surface of the discharge cylinder, and spiral feeding blades fixedly connected to the outer surface of the transmission cylinder.

[0008] Furthermore, in order to drive the transmission cylinder to rotate and grind, the transmission rod mechanism includes a driven gear ring fixedly connected to one side of the outer surface of the transmission cylinder, a transmission motor fixedly installed on one side of the discharge cylinder, a reducer fixedly connected to one end of the transmission shaft of the transmission motor, and a driving gear fixedly connected to one side of the output shaft of the reducer. The driving gear meshes with the driven gear ring.

[0009] Furthermore, in order to replace the ball mill cylinder inside the transmission cylinder, the loading and unloading mechanism includes a loading and unloading groove on one side of the inner wall of the transmission cylinder, a transmission screw is rotatably installed inside the loading and unloading groove, and a positioning block is fixedly connected to one side of the outer surface of the ball mill cylinder, and the positioning block is threadedly connected to the transmission screw.

[0010] Furthermore, to facilitate feeding into the ball mill cylinder, a feeding cover is rotatably installed at one end of the transmission cylinder, a support frame is fixedly connected to the bottom of the feeding cover, and a feeding pipe is fixedly connected to one side of the outer surface of the feeding cover.

[0011] Furthermore, in order to achieve efficient material transfer in the discharge cylinder by the spiral feeding blades, one end of the spiral feeding blades slides in contact with the inner wall of the discharge cylinder.

[0012] Furthermore, in order to seal one end of the transmission cylinder, positioning plates are fixedly connected to both sides of the outer surface of the transmission cylinder, and a sealing cover is fixedly installed on one side of the positioning plate by bolts.

[0013] Furthermore, in order to facilitate the turning of the transmission screw when loading and unloading the ball mill cylinder, a turning groove is provided at one end of the transmission screw.

[0014] Furthermore, in order to collect the material discharged from the discharge cylinder, a collection box is fixedly installed on one side of the bottom surface of the discharge cylinder.

[0015] Furthermore, in order to facilitate the loading and unloading of the ball mill cylinder inside the transmission cylinder, pull grooves are opened on both sides of the inner wall of the ball mill cylinder.

[0016] Furthermore, in order to enable the ball mill device to be moved and supported as a whole, casters are rotatably installed on the bottom surfaces of the support columns and support frames.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The ball mill cylinder installed inside the transmission cylinder drives the non-metallic minerals to rotate and grind inside. The ground material is then filtered through filter holes on the surface of the ball mill cylinder and discharged into the discharge cylinder. Once the material reaches the required fineness, it is automatically separated from the transmission cylinder without waiting for all the material to complete the grinding process. This not only reduces unnecessary energy consumption but also significantly shortens the single processing cycle, improving overall production efficiency. Furthermore, the material filtered into the discharge cylinder is automatically conveyed and discharged by the rotation of the spiral feeding blades, eliminating the need for manual material handling and effectively reducing labor costs and labor intensity.

[0019] 2. The loading and unloading mechanism allows for the loading, unloading, and replacement of the ball mill cylinder inside the transmission cylinder. This enables the replacement of the ball mill cylinder with filter media holes of different sizes to meet different grinding requirements, thus allowing for free adjustment of the grinding degree of the material and effectively improving the grinding quality of non-metallic minerals.
