Rotary valve is often used in lime powder.
Rotary valve is applied to discharge powder or granular material either in positive air pressure or in negative air pressure of pneumatic conveying system.Also it is a necessary device for ventilation and move dust systems.Rotary valve is especially suitable for separating and discharging powder and small particulate matter in the process of positive and negative suction.
Rotary valve is primarily used for dischang of bulk soild material from hoppers/bins,receivers,and cyclones into a pressure or vacuum-driven pneumatic conveying system.Components of a rotary valve include a rotor shaft,housing,end plate,and packing seals and bearings.Rotors have large vanes cast or welded on and are typically driven by small internal combusyion enginesor electric motors.
