In the entire process of graphite product production, the grinding link is crucial. Generally, the calcined petroleum coke is crushed and ground by a crusher and a grinder to obtain petroleum coke fine powder with a particle size of 200 mesh. The fineness distribution of the product after grinding and the purity of the finished powder will affect the quality of graphite products. In the field of carbon and graphite products, the performance requirements of the mill are relatively high. Zenith Machinery's star product MTW European version grinding mill perfectly matches the needs of graphite production companies. The finished product has a reasonable fineness distribution, high purity of finished powder, large output, energy saving and environmental protection. It can be combined with the customer's specific process requirements and product fineness requirements to scientifically and reasonably configure the feeding system, main machine grinding system, grading system, fan and collection system.
