Pneumatic conveying

Pneumatic conveyor systems and vacuum cleaning systems for your bulk material

Pneumatic conveying is the most economical way of gently transporting powders and granulates over long distances, both horizontally and vertically. The transport speeds are adapted to the technical requirements and the product characteristics. Whether dilute phase conveying or dense-phase conveying: we offer you all technical solutions. In addition, there is the possibility of carrying out tests with your product in our extensively equipped technical centre. This supports the planning for your pneumatic conveyor system.

We also offer various dust extraction systems in mobile and stationary versions. They ensure the effective cleaning of complex industrial plants and impress our customers with their safe, environmentally friendly technology, high-quality workmanship, and long-lasting quality.

Pressure vessel conveying

  • For dense phase or peristaltic feed
  • Gentle pressure conveying of the products due to slow conveying speed
  • Low wear of the conveyor components
  • Very long conveying distances (up to approx. 250 m) with variable pipe laying
  • Very high conveying capacities (up to approx. 50 t/h) due to high product loading
  • Low energy costs due to the small amounts of air that are required
  • Use of the existing compressed air network or by blower
  • Conveying to several reception points with only one pressure transmitter

Rotary valve conveying

  • Cost-effective alternative to pressure vessel conveying
  • Simple and space-saving installation of the system
  • Variable setting of the delivery rate by adjusting the speed of the rotary valve
  • Long conveying distances (up to approx. 150 m) with variable pipe laying
  • High conveying capacities (up to approx. 30 t/h) possible thanks to optimal conveying routes
  • Feeding several reception points with only one rotary valve
  • Best spare parts availability through the use of well-known manufacturers

Vacuum conveying type VFS

  • Our recommendation for the chemical industry
  • Batch operation of the plant for powder and granules
  • Filter system completely in stainless steel – sintered metal
  • Absolutely gas-tight, thus inertisation and nitrogen cleaning of the system is possible
  • Wet cleaning of the separation area with integrated cleaning nozzles
  • Conveying distances (up to approx. 50 m) with variable pipeline laying via fixed pipes or wear-resistant conveying hoses
  • Delivery rates up to approx. 3 t/h
  • Conveying products from several feeding points to one receiving point

Suction conveying via feed valve or injector

  • Continuous operation of the suction conveying system
  • Simple and space-saving installation of the system
  • Absolutely dust-tight thanks to constant negative pressure in the system
  • Variable adjustment of the delivery rate through speed adjustment of the discharge valve
  • Long conveying distances (up to approx. 120 m) with variable pipe laying
  • Good conveying capacities (up to approx. 10 t/h) thanks to optimal conveying routes
  • Conveying products from several feeding points to one receiving point
  • Use of well-known component manufacturers

Stationary vacuum cleaner

  • Improve hygiene requirements when you retrofit the central vacuum cleaning system
  • Improvement of working conditions, through individually planned vacuum cleaners
  • Robust construction for the highest loads in continuous operation
  • Minimal personnel costs thanks to several extraction points
  • Greater cleanliness through closed dust disposal and recirculation systems
  • Increase of service life by reducing filter load via a pre-separator
  • Long suction length up to 400 m

Sensitive primary products have to be conveyed gently over a long distance in a chemical plant.

The solution

  • Since pressure transmitters convey at low speed, they are particularly suitable for gentle transport over long distances.
  • At the central feeding point, the pressure transmitter vessels are filled and conveyed to the receiving points as required.
  • The distribution to the individual lines is done by 2-way switches.

The refilling of several dosing containers with highly dusty and very fine metal oxides.

The solution

  • A vacuum suction conveyor with 7µm stainless steel sintered metal filter.
  • A conveying capacity of 80 kg/h with a conveying distance of about 25 m.
  • Distribution to 2 dosing points by means of a pipe diverter.

In the production of cables, plastic granulates have to be transported in different quantities over long distances to different extruders.

The solution

  • Depending on the requirements, the individual granulates are dosed by their weight.
  • The feed into the delivery line takes place via a blow-through valve.
  • The conveying air is cooled beforehand to prevent strand formation and angel hair.

Power plants produce a lot of fine coal dust, which is highly combustible and must therefore be removed regularly.

The solution

  • A pipe network several hundred metres long, and fitted with several suction points with self-closing valves, was laid in the power plant.
  • Hoses with vacuum cleaners can be connected to the pipe network at 2-3 different points at the same time.
  • The dust is collected in a receiving container with filter and enters a humidifying mixer via a flap sluice.
  • The moistened dust is fed into the incinerator.

In power plants, a lot of dust accumulates in places that are far apart. What is needed is a solution that allows for easy cleaning of these areas.

The solution

  • Mobile vacuum cleaners are taken to collection points for suction lines and connected there. They only need a power connection and then work completely self-sufficiently
  • They are pulled to docking points for emptying. There, the collected dust is discharged, mixed with water and added to the fresh coal as earth-moist material.
