3. CONFIGURATION All models of the grain cleaner Metra ADS are supplied in basic configuration. If desired, the equipment can be changed with a new contract. Complete set: Grain cleaner Metra ADS. 2. Certificate. 4. DISTINCTIVE FEATURES 4.1. Overall design: The Metra Separators are equipment for separating bulk materials on fractions within the airflow generated inside the separation chamber.
5. OPERATION • The Metra Separator grades source material in the airflow. • Initial grading is performed due to differences of weight and windage properties. • Heavy impurities, like stones, are separated into the first output tray. • Seeds of the highest sowing quality (the most viable, with the highest germination capacity) are directed into the second and third output trays.
6.2. Control labeling: Controls of the Metra Separator operation, the buttons/switches are the following: - ‘ON’ - ‘OFF’ - ‘START’ - ‘STOP’ - ‘ROTATION DIRECTION’ - ‘SPEED’ - ‘EMERGENCY STOP’. 7.
