Introduction
The rotary valve is used for continuous and even feeding of dry materials in the form of powder or small particles from the upper bin into the next piece of equipment. It is an auxiliary conveyor device. It is widely used as feeding equipment for a materials system in cement, building materials, chemicals, metallurgy and light industries.
Principle
The rotary valve is a constant feeder. This machine is equipped with a BLY series cycloidal-pin gear speed reducer, and it connects rigidly with the main shaft through the output shaft, driving the main shaft and impeller to rotate. The main shaft and impeller rotate simultaneously when the motor is rotating on the impeller. Materials in the upper bin enter into the trough of the impeller through the feed inlet and are conveyed to the outlet by the rotating impeller.
Structure
Firmly structured and exquisitely designed, this machine is assembled with a shell, impeller, end cover of the main shaft and other components, and is equipped with a BLY series cycloidal-pin gear speed reducer.

Installation Notes
1, the rotary valve must be kept clean, especially the inner body of main case.
2, check all fasteners to ensure that the connection is reliable, the machine is (including motor) with good grounding.
3, the flange under and upper the vane feeder must be fixed firmly, make the whole machine is in a state level at the same time
4, check the wiring of motor, make it has start conditions.
Operation notes
1.Pay attention that when start the power supply if motor high heats, you have to stop and inspect, so as not to affect normal operation of the speed reducer.
2.If powder leakage phenomenon is found on the shaft, you should tighten the packing gland bolts on both ends.
3.During operation , check the heat of bearing place, general bearing temperature rise shall not be more than 60 ºC.
4.During operation, if you find abnormal vibration, please stop and exclude it.
5.If found that bolt looseness in the process of operation, it should be tighten.
