Inverter technology helps traditional ball mills develop automation processes

As the preferred equipment for crushing large construction waste and various mining materials, ball mills are widely used in mineral processing, building materials, chemical industry and other industries. Ball mills can be divided into dry and wet types according to the different grinding methods, and various ores and other grindable materials can be dry or wet ground. According to different discharge methods, they can be divided into grid type and overflow type.

As a low-speed heavy-load equipment, the ball mill has a large load capacity and a large starting torque. Traditional ball mills usually need to be equipped with hydraulic couplings to improve the starting and speed regulation functions of the transmission system. For example, ceramic industrial ball mills usually use additional starting motor impact starting or soft starting devices to start, which has a great impact on the power grid, and the torque required for operation after the start is completed is reduced and the energy consumption is large. Therefore, traditional ball mills have many limitations.
