Dilute, or lean phase, pneumatic conveying systems are the perfect solution for many non-sensitive and non-abrasive powders or bulk materials. The process can be designed as vacuum or pressure system.
They also offer advantages if only limited headroom is available for the system installation.
Rotary valves
The product is usually introduced by means of a rotary valve into the piping system. The rotary valve acts as an airlock. A sufficiently high gas velocity (typically >20m/s) is required to keep the particles in suspension (keep the particles "flying") and to convey the bulk solids into the receiving hopper.
Gericke offers a full range of rotary valves with its RotaVal products. This includes options for easy cleaning, hygienic applications and heavy duty requirements.
