This machine has been designed to remove in a short amount of time both fine and large impurities that can be found in grain. It is installed on an easily transportable trailer (*0km/h street version and *0km/h for internal use) and is used before storing or shipping the product.

CONSTRUCTION
- Structure, casing and drum support pillars made of pressed, galvanized sheet metal - Movable side doors with handle and lock - Carbon steel perforated screens - Manual drum inclination - Nylon brush for screen cleaning - Fixed rotation speed - Extraction spiral - Aspiration intake

OPERATION
The unclean product is loaded through a tubular auger and enters the rotating drum. The first perforated screens remove the finer impurities and the subsequent screens divide and pass the desired product through the associated perforations. At the end of the screens, the larger impurities are eliminated. Depending on the type of product (smoother or rougher) the inclination of the drum can be adjusted in order to optimize the performance of all the screens. A control system for each screen allows for uniform distribution of the product which is then traversed by an airflow to remove lighter particles. The cleaned product is conveyed into the second tubular auger, connected to the inclined tubular auger. It is possible to send the by-product into the third tubular auger, connected to the vertical auger. The heavier dust particles are decanted and conveyed in the fourth auger, which is connected to the vertical auger. The airflow is directed to a cyclone to suppress lighter dust particles. The heavier dust particles are sent to the fourth auger, or discharged using the appropriate slide.
