Invest in the most effective control solution for ball mills?

The solution uses INVT’s GD200A inverter to control the ball mill, helping to improve working efficiency and save energy.

Ball mill is equipment used to grind dry and wet materials in many industries such as cement, refractory materials, silicates, new building materials, fertilizers, non-ferrous metals, glass, ceramics, etc.

The old operating method, the ball mill is usually controlled with the following method:

Main motor: Use Star/Triangle control method or soft start. Motor always operates at 100% rated speed.
Auxiliary motor: Directly started and performed only in the beginning before grinding takes place.

CUSTOMERS’ DIFFICULTIES

Difficult to start, large starting current causes mains voltage drop. Cannot work when the power grid is unstable or unstable.
It is easy to damage mechanical parts such as Puly, bearings, etc.
The engine is always running at maximum capacity, causing energy loss
Time consuming, maintenance and service costs

SOLUTION ANALYSIS

Use GD200A inverter for main motor to start smoothly and control the speed of each grinding stage of the machine.
Collection and storage of data Design a system that collects and stores the speed and time of the crushing stages of each type of crushed material through the HMI display.

SOLUTION ADVANTAGES
