The main shunt equipment in the coa

The main shunt equipment in the coal preparation plant is a shunt box and a shunt valve. Most foreign or foreign-funded enterprises use the diverter valve, which has the advantages of simple structure and simple operation, but it has high failure rate, fast wear and poor linear regulation performance; most domestic coal preparation plants generally use the diverter box as the diverter equipment. For example, Antaibao Coal Preparation Plant adopts a new type of structural shunt box. The shunt box is equipped with a flap mechanism with a guard plate, which overcomes the shortcomings of the above various shunt equipment. After field operation, the effect is good.
