A rotary feeder, also called a rotary valve or rotary discharger, is a key component in bulk material handling systems. It controls the flow of powders, granules, and pellets from hoppers, silos, and dust collectors while keeping a stable airlock seal. Our rotary feeders are made for continuous duty, precise metering, low maintenance, and long service life, serving chemical, food, pharmaceutical, cement, mining, and environmental industries.

We offer both stainless steel and carbon steel rotary dischargers. Stainless steel models resist corrosion and are easy to clean, making them ideal for food, pharmaceutical, and chemical applications. Carbon steel models provide strong and economical performance for cement, mineral, and general industrial use. Each unit has precision-machined rotors, robust bearings, and adjustable packing seals to prevent leakage and pressure loss.

Our rotary discharge valves come in many models and sizes, from small laboratory feeders to large industrial rotary locks. We supply closed-end, open-end, adjustable, and blow-through rotor designs. The right configuration is selected based on material characteristics, conveying pressure, temperature, and required throughput. For sticky or abrasive materials, special rotor pockets and wear-resistant liners can be added. For high-temperature processes, heat-dissipating covers and cooling fins are available.

Proper model selection is essential. Our engineers evaluate bulk density, particle size, flowability, moisture content, inlet and outlet pressure, temperature, explosion risk, and required capacity before recommending the right rotary feeder. We help customers avoid jamming, air leakage, bridging, flooding, and premature wear. By optimizing rotor clearance and pocket volume, we ensure stable feeding and accurate material flow, reducing downtime and ownership cost.

Quality is controlled throughout production. We use CNC machining and automatic welding to ensure consistent dimensions and strong construction. Every rotary feeder undergoes clearance measurement, running-in testing, sealing air testing, and pressure testing according to customer specifications. Our quality system follows ISO 9001 standards, and all products are traceable from raw materials to final assembly.

Rotary feeders are widely used in pneumatic conveying systems to feed material into pressure lines while maintaining system pressure. In dust collectors, they discharge dust continuously and prevent hopper blockage. In batching plants, they provide accurate feed for mixing recipes. In drying and cooling systems, they distribute material evenly. They are also used in pellet mills, powder coating lines, sand blasting machines, and chemical dosing equipment.

Proper installation and maintenance extend service life. The manual gives clear instructions for lubrication, clearance adjustment, and seal replacement. We recommend regular checks of rotor tip clearance, bearing condition, and packing gland tightness. With simple preventive care, equipment operates reliably for many years. Replacement parts such as rotors, packing seals, bearings, and end covers are available for quick shipment.

Pricing for a rotary feeder depends on material of construction, rotor type, size, operating pressure, temperature rating, and accessories. Stainless steel rotary feeders usually cost more than carbon steel models because of material and machining costs. However, selecting the right configuration matters more than chasing the lowest price. We provide detailed quotations and technical guidance to help you find an economical, durable solution. Factory-direct sales reduce middleman costs and offer competitive pricing without compromising quality.

Choosing our factory gives you support from selection to after-sales service. We can customize flanges, shaft seals, coatings, and rotor materials according to drawings or process needs. Whether you need one standard rotary feeder or a complete feeding system, we are ready to be your long-term partner.
