High-capacity pre-cleaner drum for grain silo storage
In grain storage facilities, large volumes of bulk product can quickly become contaminated with foreign materials like cobs, leaves, stems, and stones. This contamination can clog dryers, reduce cleanliness, and increase maintenance requirements, making efficient pre-cleaning vital.

Efficient removal of large and small contaminants
The Pre-cleaner drum SEMB from Stolz is a specialized pre-cleaning solution designed to handle high volumes of bulk products such as cereals and other powdery materials. By removing a wide range of contaminants before storage, it ensures a cleaner and more manageable grain handling process. The SEMB features continuous operation without shocks, a dispatcher and pre-suction system at the inlet, and an adjustable feeding shovel. It efficiently removes both fine dust and large waste materials through its rotary drum with a customizable sieve mesh. The pre-cleaner also includes an expansion chamber and suction channel for effective collection of light wastes, further protecting downstream equipment and minimizing maintenance. With options like anti-filling sensors and various waste discharge hoppers, the SEMB can be tailored to specific operational needs.
