Mobile pre-cleaner
Mobile version up to 60 t/h
Our pre-cleaner is used for the high-performance pre-cleaning of your bulk material. It works according to the air classifier principle and quickly and effectively separates your product from lighter particles, such as dust or small grains. By combining it with our mobile tubular screw conveyor, the pre-cleaner can be used quickly and in any location.

The functional principle:
The Kessens pre-cleaner works according to the air classifier principle. The bulk material
is fed through the side inlet into the cleaning cone, where it is directed onto
the rotating lamella disc. All light components are sucked upwards with the
air flow through the fan and further into the cyclone. The suction power of the fan
can be regulated with
an air control flap at the fan outlet.

Mobile version with screen tube cleaning
The combination of air classifier technology and screen cleaning achieves optimal cleaning results. By using screen tube cleaning on the mobile tubular screw conveyor, particles that are smaller and heavier than the grain to be cleaned (such as sand, small stones) are separated during transport and discharged via the outlet in the dust box. Subsequently, the lighter particles (such as dust) are separated according to the air classifier principle.

- Excellent cleaning result
- Removal of dust, sand, small stones, soil, …
