Grid Machine

The rotary rake grid machine is a special water treatment equipment that can continuously and automatically intercept and remove various-shaped debris in the fluid. It can be widely used in urban sewage treatment, the water supply industry, and the water inlet of power plants. At the same time, it can also be used as the pre-screening equipment in the wastewater treatment process of industries such as textiles, food processing, papermaking, and leather. It is one of the current advanced solid-liquid screening equipment.

The greatest advantages of this equipment are its high degree of automation, high separation efficiency, low power consumption, no noise, and good corrosion resistance.

Due to the reasonable structural design of the equipment, when the equipment is working, it has a strong self-cleaning ablity and no clogging occurs, so the daily maintenance workload is very small.
