What is a completed white clay powder grinding mill?

White clay is a mixture, which is a kind of clay and clay rock mainly composed of kaolinite group clay minerals. Because it is white and delicate, it is also called white cloud soil. It belongs to non-metallic mineral, and can be used as paper coating, ceramics and filler. It has a good market application prospect. It is a good business opportunity to open a white clay powder factory.

White clay powder grinding mill and its process flow

The white clay is mainly composed of kaolin earth rock group clay minerals, and its Mohs hardness is Grade 2. The finished product is generally more than 325 meshes. According to the material characteristics, it is recommended to select white clay Raymond mill or white clay vertical roller mill, and at the same time, some auxiliary equipment to form a production line. The specific production process of white clay powder grinding mill is as follows:

(1) white clay powder grinding mill

① White clay Raymond mill: as a common white clay grinding mill on the market today, it has a vertical structure, small floor area and strong completeness. From block material to finished product, it is an independent production system, reducing workshop staffing, with high efficiency, good and uniform quality of finished fine powder, high sorting accuracy, higher screening rate, and fineness can be adjusted according to demand.

System composition: raw material bin → elevator → crusher → white clay Raymond mill → feeder → classifier → collector → pipeline device → dust remover → power distribution cabinet → finished product bin;

② White clay vertical roller mill: white clay vertical roller mill is a mainstream equipment on the market. Its unique grinding process has high grinding efficiency, strong drying capacity and low integrated structure comprehensive investment cost. Raw materials are ground into finished products. The product has uniform particle shape, narrow particle size distribution, good fluidity, strong adaptability, little iron content in the product, and high whiteness and purity.

System composition: raw material bin → elevator → crusher → feeder → drive motor → white clay vertical roller mill → classifier → pulse collector → blower → piping system → power distribution cabinet → finished product bin;

(2) Production process flow of white clay powder grinding mill

Stage I: crushing of raw materials

The white clay bulk material is crushed by the crusher to the feeding fineness (15mm-50mm) that can enter the white clay grinding mill.

Stage II: Grinding

The small pieces of crushed white clay are sent to the storage hopper by the elevator, and then sent to the grinding chamber of the mill for grinding in a uniform and quantitative manner by the feeder.

Stage III: Grading

The material after grinding is graded by the grading system, and the unqualified powder is graded by the grader and returned to the host machine for regrinding.

Stage IV: Collection of finished products

The fine powder enters the dust collector along with the gas through the pipeline for separation and collection. The collected finished powder is sent to the finished product silo through the outlet by the conveyor, and then uniformly packaged with powder loading tanker or automatic packer.
