● Product Overview

Traditional wet sand making equipment often uses rod mills, but there are disadvantages such as disorderly rods and high steel consumption during the production process. Based on years of production experience, our company has developed and successfully applied an efficient sand making specialized ball mill to replace the rod mill. Compared with rod mills of the same scale, the production capacity has increased by nearly 50%, the powder pass rate has decreased by 10%, the steel consumption has decreased by 200%, and the economic benefits have significantly improved.

● Working principle

When the ball mill is working, the material is loaded into the cylinder through the hollow shaft at the feeding end. When the ball mill cylinder rotates, the grinding body is attached to the cylinder lining plate and carried away by the cylinder due to inertia, centrifugal force, and friction force. When it is carried to a certain height, it is thrown down due to its own weight, and the falling grinding body shatters the material inside the cylinder like a projectile. The material is uniformly fed into the first compartment of the ball mill through the hollow shaft screw of the feeding device. There are stepped or corrugated liners in the compartment, which are filled with steel balls of different specifications. The rotation of the cylinder generates centrifugal force, which brings the steel balls to a certain height and then drops them, causing heavy impact and grinding on the material. After the material reaches rough grinding in the first warehouse, it enters the second warehouse through a single-layer partition plate. The warehouse is lined with a flat lining plate and contains steel balls for further grinding of the material. The powdered material is discharged through the discharge grate to complete the grinding operation.

● Product advantages

1. The high-efficiency sand making special ball mill adopts anisotropic wear-resistant lining plate and multi-faceted steel balls

2. The transmission adopts large double row self-aligning roller bearings instead of sliding bearings, which greatly reduces friction, makes it easy to start, and saves 20% -30% energy

3. The use of drum shaped feeders instead of combined feeders not only significantly saves energy, but also greatly reduces maintenance time
