We offer our customers nine well-proven and matured systems for pressure and vacuum conveying with components manufactured by ourselves. In this way, we always find a suitable solution for every product and every specific task.
Solids puls pneu
Low velocity conveying with secondary line (bypass system), impulse valve and relay stations (slow pressure conveying system)
Plugs are generated and preserved and pushed through the conveying line. Gentlest low velocity conveying system for sensitive and abrasive products. Full pipe system.
Advantages
- Segregation-free conveying through stable product plugs in the conveying line
- Gentle transport for sensitive products thanks to the low conveying speed
- Low-wear conveying system through low conveying speed, pure linear movement of the material plugs
- Possibility to start up a filled conveying line after a power or pressure air failure
Suitable for
Sugar, spray granules, instant products, milk powder, carbon silicide, abradants, hard minerals, sodium percarbonate, instant coffee, adipic acid, pelletised carbon black, flakes, chips
Unique plug conveying
Already in 1970, HOSOKAWA solids developed a complete procedure for pneumatic plug conveying. So far, more than 1,000 systems for thousands of different products are planned and built according to this concept in all the countries of Europe, the USA, Japan and India. It features an impulse valve to form plugs and a secondary line with so-called relay stations to keep the plugs and continue their transport without dissolving them.
Outstanding properties
- Practically unlimited conveying ways and conveying capacity
- No clogging at low speed and high loading
- Slow conveying and gentle conveying from approx. 0,5 m/sec
- Almost wear-free even for extremely hard and abrasive bulk materials such as silicon carbide or abrasives
- Almost no grain destruction and minimal abrasion of highly sensitive products such as spray granules
- No segregation in mixtures and processed masses
- Low energy costs through efficient use of pressure energy
- Functionally reliable even with moist, cohesive, sticky, not lowable bulk goods
