DN300 Caliber Pneumatic Conveying Powder Stainless Steel Rotary Feeder

Rotary Feeder Description:

Powder type rotary feeder, also commonly known as rotary valve or rotary feeder in the industry, is an indispensable key equipment in pneumatic conveying systems and powder processing processes. It is specifically designed for precise measurement, continuous and controllable transportation of dry powdered materials, while effectively isolating upstream and downstream pressure differences to ensure efficient, stable, and dust-free operation of the system

Rotary Feeder Core functions and application value:

Accurate measurement and uniform feeding: By adjusting the speed of the rotor, precise control of powder flow is achieved to ensure continuous and uniform material supply to downstream equipment (such as mixers, packaging machines, reaction vessels) or pneumatic conveying pipelines.

Efficient pneumatic air lock: In pneumatic conveying systems, the rotary feeder is the core "locking valve". Its precise rotor and shell clearance design can effectively isolate the high pressure (or negative pressure) of the conveying pipeline from the upstream material bin (normal pressure or slight negative pressure), prevent gas backflow or leakage, maintain system pressure stability, and ensure conveying efficiency.

Dust control and environmental protection: Excellent sealing performance (including end cap sealing and blade sealing) minimizes material leakage during transportation, protects the working environment, and complies with strict dust emissions and occupational health and safety.

standardsSmooth conveying to prevent bridging: Optimized rotor structure and shell design help to break down potential "bridging" or "rat holes" formed by powder materials, promoting smooth and reliable flow of materials into the rotor compartment and ensuring continuous feeding

Rotary Feeder Typical application Industry:

1.Chemical industry: plastic pellets/powders, pigments, dyes, catalysts, additives, etc.
2.Food industry: flour, sugar, milk powder, starch, seasonings, food additives, etc.
3.Pharmaceutical industry: raw material powders, excipients, granules, etc. (must comply with GMP requirements).
4.Mineral processing: cement, lime powder, fly ash, mineral powder, fillers, etc.
5.Energy and environmental protection: biomass particles/powders, activated carbon, desulfurizers, etc.
6.Plastic and rubber: resin particles/powders, carbon black, rubber powder, etc.
7.Building materials: gypsum powder, dry mixed mortar raw materials, etc.
