Grid type ball mill

Product introduction

The bottom of Xinhai grid ball mill is equipped with a hydraulic jacking device (replacing the conventional jack). It not only makes the operation simpler and more convenient, but also improves the stability of the lifting and lowering of the ball mill and can be kept at the same level, reducing the failure rate of the ball mill.

Performance Features

1. The transmission device of the ball mill is equipped with a slow-speed transmission system device, which reduces the impact force and energy consumption when the ball mill starts and stops instantly.

2. The end cover of the ball mill feed is made of ZG310-570 cast steel and is made of integral casting; the bolts are sealed with polyurethane gaskets, which improves the problem of slurry leakage. ;The feed end lining plate is made of -ZGVn13 casting material, which can effectively extend the life of the end cover.

3. The large and small gears use Xinhai's innovative spray lubrication system. When an oil film is formed, it is in the liquid friction zone, and the friction becomes smaller, which can greatly reduce Friction to achieve energy saving effect.

4. There are three feeding devices to choose from, namely drum feeder, combined feeder and feeding trolley. Among them, the drum feeder is suitable for use with a single screw classifier or cyclone; the combined feeder is suitable for use with a double screw classifier; the feeding trolley can move forward and backward on the track, and is only suitable for large ball mills above 32 meters. .

5. It can be customized into rolling bearings and sliding bearings according to needs; according to the ball mill Depending on the size of the processing capacity, it can be configured as an integral rack device or an extension device; international accessories, such as motors, reducers, bearings, etc., can be configured according to user needs.

Product structure

How it works

The working principle of the lattice ball mill is that the rotation of the cylinder drives the steel balls and materials to perform parabolic operations, during which impact, grinding, and crushing operations are achieved. When discharging ore, because the hollow shaft at the discharging end is equipped with a special grid plate with inverted trapezoidal pores, the ore particles that meet the particle size requirements during the grinding process will enter the fan-shaped chamber through the gaps on the grid plate along with the slurry. As the end cap rotates, the slurry flows into the hollow journal along the fan-shaped chamber wall, and is discharged from the ball mill through the hollow journal to complete grinding.
