The materials that vertical roller mill can process, no matter which one, must meet the feed size and the size can not exceed 20 mm, but the size of the original ore is relatively large, so in the production line, the crushing equipment needs to be first The calcite is broken, and then the grinding operation is carried out by the vertical roller mill to select which crusher to choose. Mainly based on the production situation.

The broken calcite needs to be transported to the vertical roller mill for processing. Therefore, when working, a conveyor equipment, a belt conveyor, and a feeder are required. The choice of these two machines is also required. The actual situation of production and the model of the mill are determined; vertical mill has also obtained some applications in the non-metallic mining industry.
