Rotary Feeder for Powder Pellet Solid Materials

Introduction

Rotary valve is a special device used in discharging, packaging, mixing, dust-filtering, metering and quantitive conveying in conveying system for solid materials such as powder, pellet and powder-pellet mixture.

Working Principle

Driven by a motor or a speed reducer, a vane wheel with uniform structure is rotating in a shell. The material falling from bin or feeder above the shell fills in the cavity of vane wheel. Then the material discharge out of the bottom side of the shell while vane wheel is rotating. In this way, the material can be discharge evenly and constantly downstream according to the requirements of conveying system.

Classification

Rotary valve can be classified into block-proof rotary valve, high pressure rotary valve, cleaning rotary valve used in gravity discharge, pneumatic conveying system and aseptic conditions.

Solutions

1. Evenly discharging in gravity discharge.

2. Air-locking function in pneumatic conveying.

3. Pressure resistance in pressure conveying.

4. Block-proof conditions.

5. Cleaning function in food and pharmacy industries.

Features

1. Compact and sturdy design, exquisite and good-looking.

2. The shell and vane wheel has a special structure design and are treated specially. Therefore, the rotary valve can convey special materials, such as high temperature, high pressure, high hardness, and high stickiness, superfine and generable static electricity.

3. High machining and assembling precision ensure very small clearance.

4. Inlet and outlet opening sections is specially designed to avoid pressing blocking and shear breaking for pellet materials.

5. Exhaust passage and connector in the shell for pressure balancing. Work efficiency can be increased and no material pile-up.

6. Polishing precision up to 400#, applicable for food and pharmacy grade materials.

7. Main body materials can be chosen from stainless steel (SS304, SS304L, SS316, S316L, SS836L), carbon steel and ductile iron according to your specific application.

8. Cycloidal pin gear speed reducer as drive, configured a Frequency inverter or CVT machine to realize quantitive or variable conveying.

9. In the circumstance of zero protection function, a sensor can be installed on the top of the rotary valve to realize online and on-site supervision.
