Application of Roller Press in Slag Final Grinding System

Slag Roller machine Flow: Material is dispersed and dried immediately after entering V-type flour separator. The host deals with the slag that has lost its viscosity. Fine slag powder has been dried. It is directly fed into high-efficiency dynamic flour separator by long pipeline, where the slag powder is sorted and finally dried. The heat source of slag drying is provided by coal-fired hot blast stove. The wet slag can be dispersed and dried in V-type separator, long pipeline, and high-efficiency dynamic separator to meet the moisture requirement of drying.

The practice has proved that the slag particle size of roller machine and vertical grinding process is the same, and the slag particle size of ball grinding process is the smallest, that is, the fine particle content of ball grinding slag powder is high (< 30 microns), and the coarse particle content is low. The distribution of slag powder particles in a ball mill is wider than that in a roller machine and vertical mill, and there is little difference between a roller machine and vertical mill.

Roller machine and vertical mill are widely used power-saving equipment in a grinding system in recent ten years. The vertical mill has been widely used in slag final grinding, while roller machine is mostly used in the combined grinding system. The practice has proved that the roller mill used in final grinding of slag can be comparable to vertical grinding, with comparable power-saving effect, lower investment, better market prospects, and popularization value.
