Wet ball mill

Product Introduction

A wet ball mill is a key piece of equipment for pulverizing materials after crushing. It consists of a feed section, a discharge section, a rotary section, and a transmission section. DMG Heavy Machinery's wet ball mills are used in industries such as cement, silicate products, new building materials, refractories, fertilizers, ferrous and non-ferrous metal beneficiation, and glass and ceramics, performing dry or wet grinding of various ores and other grindable materials.

Operating Principle

A motor drives the drum through a reduction gear. The crushed ore and steel balls in the drum are lifted to a certain height by the liner due to friction and centrifugal force. Gravity then causes them to fall and cascade, gradually crushing the ore through the impact and grinding action. The crushed ore is discharged from the drum through the discharge section. The discharged ore is then classified in a spiral classifier to produce qualified products. The coarse sand then passes through a combined feeder and returns to the wet ball mill for further grinding. The feeder feeds the material continuously and evenly, the ore enters the wet ball mill continuously and evenly through the combined feeder, and the ground material is discharged from the wet ball mill continuously.

Product Advantages

1. The discharge end is lower than traditional ball mills, resulting in faster discharge speeds and a coarser, more uneven product particle size.

2. Compared to overflow-type ball mills of the same model, the production capacity is 20%-30% higher and energy efficiency is 10%-30% higher than overflow-type ball mills.

3. It is primarily used for single-stage grinding and is often paired with a spiral classifier to form a grinding circuit. It can also be paired with a cyclone.

4. It is highly adaptable to fluctuations in material physical properties (such as particle size, moisture content, and hardness).

5. Slow-speed transmission facilitates maintenance and startup.

6. It can be installed with cast iron liners, rubber liners, and magnetic liners for easy maintenance.

7. Large ball mills utilize dynamic and static pressure or fully static pressure bearings and an air clutch, reducing starting current and protecting the motor.

8. It can be driven by either a synchronous or asynchronous motor.

9. It is equipped with a slow transmission and lifting device for easy maintenance.
