The kaolin production process of grinding powder and gravel mainly includes two-stage crushing and three-stage crushing. small-scale grinding powder and gravel production lines mostly use two-stage crushing and screening processes. some large-scale grinding powder and gravel production lines mostly use three-stage crushing due to the large size of materials. crushing and screening process.
generally speaking, the production of kaolin grinding powder mostly adopts three-stage crushing, namely coarse crushing, medium and fine crushing, and sand making:
coarse crushing generally adopts jaw crusher;
secondary crushing generally adopts impact crusher;
fine crushing and sand making generally use vertical shaft crusher or cone crusher.
From its working principle, we can see that the structure of the kaolin grinding mill is simple. From raw materials to finished products, only 2~3s stay in the crushing cavity, so the throughput of raw materials is very large, the production volume is high, and the processing efficiency is strong. Stone granularity and appearance are easy to handle and control. At the same time, the crushing principle of stone-on-stone is adopted, and the wear on the wearing parts is relatively small. The wearing parts are made of high hardness, high toughness and multi-component alloy wear-resistant materials, and the service life of the whole machine is increased by 2-3 times. , glass, ceramics, electricity and other fields are widely used, and many users have reported that the kaolin grinding mill is very effective!
