Rotary Air Lock Feeders

Mashine Design manufactures rotary air lock feeders used to regulate the flow of material while creating an air lock. They are also used to feed material from silos/hoppers at a controlled rate and are used in number of other pneumatic applications acting as an air lock barrier between the up and down streams. Rotary air lock feeders can also sustain heavy differential pressures and temperature. The rotary air lock feeders are manufactured in different variants such as drop-through, blow-through, off-set, etc. The dropthrough or in-line type is the most commonly used feeder and suitable for general applications. The blow-through version is used in pneumatic conveying applications where the material is blown away by the incoming stream of air from the pipeline. The off-set type is used to handle particularly hard, uncrushable particles, which jam/seize the rotor during operation. They can be provided with various types of rotors such as fixed-tip, flex-tip, deep-pocket, shallow-pocket, closed rotor, open rotor etc. depending upon the application. The material of construction is MS, SS 304 SS 316, CI, cast steel and other special materials, depending upon the application. The rotary air lock feeders are provided with round/square flanges to match the preceeding equipment. For food and pharma industries special, fast cleaning rotary air lock feeders can be provided. The company can customise and design rotary air lock feeders for special requirements.
