Wet Grid Type Ball Mill

The working principle of Huston wet grid ball mill is mainly to slowly rotate through the transmission device. The material is fed from the feeding end of the cylinder. In the cylinder, the material is crushed due to the impact and self-grinding of the steel balls and the ore itself. As materials are continuously fed, the pressure causes the materials in the cylinder to move from the feeding end to the discharge end. Materials that reach the final product size are discharged from the discharge end of the cylinder. During wet grinding, the material is brought out by the water flow; during dry grinding, the material is brought out by the air flow. The mill has a discharge grid at the discharge end. The mill relies on the grid plate to force the ore to be discharged. The slurry surface in the cylinder is low, which reduces the over-grinding of the ore and prevents the discharge of steel balls.

In an iron ore dressing plant in Yunnan, the hardness of the ore requires small grinding particle size. In order to avoid over-crushing of the ore, Huston’s wet grid ball mill was selected during the grinding stage. The wet lattice ball mill is impacted and self-grinded by steel balls and the ore itself. It has high grinding efficiency and uses static and dynamic pressure bearings. The cylinder runs smoothly and reliably, which facilitates multiple grinding of materials in the cylinder. At the same time, the lubrication device between the large and small gears of the ball mill makes the production efficiency higher. The liquid level of the ore slurry is low, the ore is discharged in time, the energy consumption is reduced, and the ideal effect is achieved.
