The FY series disc pulverizer features a compact structure, tight sealing, easy cleaning, and can be used for both dry and wet materials. The grinding disc is made of manganese steel alloy, which is durable, and the outer edge of the grinding surface is designed with an arc-shaped curved surface. The discharge particle size is small, with the finest reaching 325 mesh. It is also equipped with a mechanism for adjusting fineness and other characteristics.

I. Structural and Performance Characteristics:

1. The disc pulverizer is mainly composed of a machine body, a base, a main shaft, a movable disc, a fixed disc, an end cover, a hopper, etc.

2. Characteristics: Power is transmitted to the pulley through a V-belt to drive the main shaft to rotate, making the movable disc and the fixed disc move relatively, thereby pulverizing the sample. The particle size of the discharged material can be controlled by adjusting the gap between the grinding discs through the large handwheel, small handwheel, main shaft, etc. The machine body, end cover, and upper cover form a working chamber, where the material is pulverized. Materials are added from the feeding port above the end cover, enter between the two grinding discs, and the sample is pulverized due to the extrusion effect. The pulverized sample flows out from the gap between the two grinding discs and falls into the hopper below. The principle of the adjustment mechanism is: loosen the large handwheel, rotate the small handwheel to make the adjusting screw rotate and push the main shaft, causing the movable disc to move forward or backward, thereby adjusting the gap between the two grinding discs to achieve the purpose of adjusting the material particle size.
