Why do some mine owners prefer to use center drive ball mills?

What is center drive ball mill

Center drive ball mill is a kind of grinding equipment widely used in many industries, which is suitable for cement, refractory materials, chemical fertilizer, ferrous and non-ferrous metal beneficiation (such as gold, copper, iron ore, etc.) and glass ceramics and other production industries. It is characterized by high efficiency, energy saving and compact structure.

The following is a detailed introduction about center drive ball mill:

1. Introduction

Center-driven ball mill is a ball mill in which the electric motor drives the transmission shaft through the reducer, and the axis of the transmission shaft is in line with the centerline of the ball mill cylinder, and the work is carried out through this transmission device.

2.Structural characteristics

1. Compact structure: all parts are located on the same axis or the same parallel axis, including the motor, fluid coupling, reducer, discharge section, main bearing and cylinder body, etc.
2. High-efficiency transmission: large double-row spherical roller bearings are used to replace the conventional pasteurized alloy lubricated bearings, which reduces the friction resistance and static resistance torque.
3. Remarkable energy saving effect: the use of hydraulic coupling to realize staged startup, reducing the installed power, while the use of hardened gear reducer, the transmission efficiency can reach 96%, which is 7.3% higher than the conventional mill transmission efficiency.

3.Working Principle

1. Transmission mode: the motor drives the mill cylinder rotating through the hydraulic coupling and gear reducer, the material enters into the mill uniformly from the feeding device through the feeding hollow shaft spiral, and is discharged by the discharging grate plate after coarse grinding.
2. Staged startup: the hydraulic coupling realizes the staged startup of the ball mill and protects the equipment from overload damage.

4.Advantages

1. high efficiency and energy saving: high transmission efficiency, significant energy saving effect, energy saving of about 5% than the edge drive ball mill. Energy saving alone can save a large amount of electricity for the manufacturer every year.
2. smooth operation: the use of hydraulic coupling and hardened gear reducer, smooth operation, low noise.
3. Convenient maintenance: compact structure, easy to maintain.
Through the above introduction, it can be seen that the center drive ball mill in the structure, working principle and application have significant advantages, is the ideal choice for a variety of industries grinding operations.
