In lead-acid battery industry, before lead powder is manufactured, the raw material lead ingot must be made into lead grain at first. Traditionally lead is mostly molten in casting grain or cutting grain. Then the grain is made into lead powder in the ball mill machine.

According to the process above, has developed this automatic production equipment for lead ingot cold pelletizing, revolutionized the traditional process of molten lead casting grain, and implemented automated production of cold lead grain. The whole equipment is controlled by PLC. This solves not only some problems (high pollution, high energy etc.) from traditional process, but also provides advantages (clean environmental protection, energy saving, efficient production etc.) for lead-acid battery industry.

 This equipment is mainly composed of the following units

◆ mechanical part,

◆ electric control system

◆ hydraulic system

◆ pneumatic system

◆ photovoltaic system

and realizes organic technology integration of PLC control, stepping control, pneumatic proportional control, hydraulic proportional control and photoelectric sensor control.
