Because iron particles have a certain ductility, poor grindability, and a large specific gravity, if they cannot be discharged from the grinding device in time, these iron particles will stay in the mill all the time, and they will accumulate slowly, seriously affecting production, increasing the power consumption of the mill operation at the same time, and accelerating the wear of the grinding table and grinding rollers due to their poor grindability.
[0003] Therefore, to solve the above problems, our company has developed and designed a grinding device for slag processing with a slag discharge hole structure for discharging iron slag particles, which is provided with a baffle ring and an iron leakage port.

It is also provided with grinding rollers and a grinding table. The rotating grinding rollers and the grinding table cooperate with each other to grind the slag more quickly, with a high degree of industrialization and greatly improving the production efficiency of the slag grinding operation process.
