TrennsoTechnik - Wind Sifter

Trennso Technik offers the solutions to material separation predominantly in sizes between 0-100 mm. With the leading technologies such as zigzag wind sifters, cross-flow wind sifters and separating tables, these machines separate materials by densities and sizes in a broad range of application

Available models

For the separation of bulk materials of varying specific weight.

The machine is used primarily for dedusting of various bulk materials. 

Functionality: 
The feed material is fed into the inlet channel and distributed evenly by
the distribution cone through the entire cross-section. The sifting air, which is sucked out from around the sifter and from underneath, flows through the feed material, flushing through it and separating it. 

Material with a higher density sinks more quickly as a result of gravity. Lightweight material is sucked out of the separating channel via the air flow, which is directed upwards. Separation of the product is controlled by dampers and suction holes. 

The wind sifter can be operated in extract air or in air recirculation mode.
The extracted air is cleaned in a downstream filtration system or by a cyclone filter.

For the separation of bulk material of varying specific weights.

The machine separates coarse bulk material according to its shape and size. 

Functionality: 
The feed material is fed into the cross-flow sifter‘s chute and distributed across the sifter‘s entire cross-section. The sifting air generated by the fan flows through the sifter horizontally across the whole length of the machine. This causes the material to be diverted and thus separated according to its specific weight. 

Material with a higher density sinks more quickly as a result of gravity and is fed out via outlet 1. Medium-weight products are diverted by a horizontally- directed airstream and fed out via outlet 2. Lightweight material is picked up by the airstream and separated by suction. Cross-cuts are controlled by air dampers, the positioning of the inflow shaft and the amount of air. 

The wind sifter can be operated in extract air or in air recirculation mode.
The extracted air is cleaned in a downstream filtration system or by a cyclone filter.

For the separation of bulk material of varying specific weights.

The machine sorts various bulk materials according to their specific gravity, their shape and size.

Functionality:
The sorting product is fed into the zigzag channel and distributed through the entire cross-section of the sorting channel. The sorting air generated by the fan flows through the sorter from the bottom to the top; this causes the material to be flooded by air and separated. 

The product must cross through the air flow at every bend in the sorting channel and subsequentlwall of the sorter. This causes the material with a higher density to drop to the bottom in the sorting channel due to the centrifugal force. The lightweight material is sucked out of the sorting channel via the upwards directed air flow.y collides against the opposite

The depth of the air sifter can be adjusted; as a result, it can be operated in extract air or in air recirculation mode. The extracted air is cleaned in a downstream filtration system or by a cyclone filter.
