Pneumatic conveying is achieved with the following Hosokawa Solids Solutions components for pressure and vacuum conveying: Pneumatic transmitters (vessel conveying), blow-through rotary valves (rotary valve conveying), Vacu Fill cycle suction conveyors (vacuum conveying), diverters and conveying line parts. They are used in the heavy industry in mild steel as well as in the fine chemical industry in stainless steel.
Both dense phase and lean-phase conveying methods in pressure or vacuum operation are possible. The conveying method with the suitable equipment is determined according to the bulk material properties, the customer requirements and the constraints.
These components are usually designed and supplied as a complete package for the respective conveying task. However, they are also available individually, e.g. batch vacuum conveyor with suction lance for manual suction from barrels/containers.
Hosokawa Solids, specialist for bulk solids handling, is part of the Hosokwa Alpine Group since 2020.
The choice of conveying method depends primarily on the material to be conveyed and your individual application. A distinction is made here between dense phase conveying (strand conveying and plug conveying) and dilute phase conveying (lean phase conveying).
Dense phase conveying is suitable for dry bulk materials such as powder, granulate, pellets or flakes. It is gentle on the product and segregation-free. Since a dense phase conveying system contains hardly any moving or rotating parts, the maintenance is reduced.
- For dry, free-flowing, insensitive and non-abrasive powders or bulk materials
- The material to be conveyed is sucked or blown through the pipe with relatively large quantities of air and low pressures
- Air speed: 15–40 m/s
- Pressure or vacuum operation possible

- Pneumatic conveyors in hygienic design: Pneumatic conveyor in hygienic design according to EU regulations and directives, meets GMP and FDA requirements.
- Pneumatic Conveyor, PHP type: PHP type push conveyor for pneumatic dense phase conveying in the push conveying method. Due to the high loading and slow conveying speed, it has a particularly gentle conveyance and is therefore suitable for sensitive and abrasive bulk materials. Heavy industrial version, industrial/fine chemical/hygienic version.
- Vibration conveyor, PHV heavy design type: Pneumatic dense phase conveying in the push conveying method with high loading and slow conveying speed for gentle conveying, suitable for heavy-flowing bulk materials, also for high temperatures.
- Blow-through rotary valves, DBS type: Dosing rotary valves for continuous feeding into pressure or suction conveying lines.
- Rotary valves, ZRS type with leakage air collector and blowing shoe: For pneumatic pressure conveying.
Batch vacuum conveyors:
