Mineral ball mill is the key equipment for crushing after the material is crushed. Ball mills are widely used in ore beneficiation, silicate products, new building materials, refractory materials, and glass ceramics production industries for dry or wet grinding of various ores and other grindable materials.


Working Principle

The ball mill is composed of a feeding part, discharging part, rotary part, transmission part (reducer, small transmission gear, motor, electric control), and other main parts.

The material is spirally and evenly entered into the first chamber of the mill through the feeding hollow shaft by the feeding device. There are stepped lining boards or corrugated lining boards in the chamber, and steel balls of different specifications are installed inside. The rotation of the cylinder produces centrifugal force to bring the steel balls to a certain height. After falling down, it will hit and grind the material. Materials get coarse-grind in the first warehouse, then into the second warehouse through the single compartment. The second warehouse has a flat liner and is also filled with balls, then grind the material again. The powder is discharged through the unloading grate plate to complete the grinding operation.

Baichy Ball Mill Equipment Advantages

1. The Spindle has Good Performance and High Processing Capacity

The main bearing adopts a large-diameter double-row self-aligning roller bearing instead of the original sliding bearing, which reduces friction and energy consumption, and the mill is easy to start. The structure of the end cover of the ordinary mill is retained, the large-diameter inlet and outlet, and the processing capacity are large.

2. Simple Structure and Stable Operation

The feeder is divided into two types: combined feeder and drum feeder, with a simple structure and separate installation. There is no inertial impact, the equipment runs smoothly, the downtime and maintenance time of the mill is reduced, and the efficiency is improved.

3. The Gear has a High Bending Strength

The ball mill accessories adopt shifting gears, which can eliminate the undercutting phenomenon, strengthen the gears with weak bending strength, and increase the bending strength of the gear teeth by more than double.

4. Long-Bearing Life

 The diameter of the hollow shaft at the rolling bearing part of the ball mill is thickened, which increases the radial distance between the rolling bearing and the feeding and discharging screw cylinder, which plays a certain role in heat insulation and cooling, and prolongs the service life of the bearing.

5. The Components are Wear-Resistant and Have A Long Service Life

The equipment adopts a high-strength and wear-resistant combined hammerhead, which can save materials and reduce waste; the joint of the hammerhead is equipped with reinforcing ribs, and the width of the striking end is widened, which increases the strength of the hammerhead and changes the phenomenon of the traditional machine dropping the hammerhead. Thus, the service life and safety of the hammerhead are improved.
