Advances in Pneumatic Conveying
Controlled Air Speed Conveying
- Reduced damage for friable products by maintaining minimum velocity
- Convey granules and large particulates gently
- Continuous monitoring of conveying air speeds
- Automatically maintain velocities to pre-set limits
- Constant velocity achieved for any conveying distance
- Constant velocity achieved for any feed rate
- Special Design offset rotary valves = reduced damage
- Special Design receiver/cyclones to minimise damage
Special Features
- Pipelines: Heavy duty pipe for abrasive products; stainless steel for chemical and food applications.
- Multiple Delivery Points: Diverter valves direct products to more than one receiver; flap valves for normal products, plug valves for abrasive products.
- Check Weigh: Infeed sack tips. buffer hoppers and receivers can be placed on load cells for assured transfer.
- Air Speed and Pressure Control: Constant air speed control is used for fragile products and is achieved by controlling blower outlet air volume. Pressure control is used to vary the speed of a rotary valve to maintain a constant FEED RATE for varying DENSITY.
- Bends: Standard rolled pipe bends or abrasion resistant bends; fabricated with special steel backing or lined with basalt or alumina; cast Ni-hard steel.
- Rotary Valves: These usually have a cast iron or stainless steel body with a fabricated rotor. Options available include hard steel body linings and rotor tips, food quality finishes and offset inlets.
- Hazardous Areas and Products: Precautions are taken where necessary; explosion venting, special motors, earth bonding.
