3. CONFIGURATION
4.1. Overall design:
The Metra Separators are equipment for separating bulk materials on fractions within the airflow generated inside the
separation chamber.
Application of the impeller in the Metra Separator provides the following advantages:
* Minimal airflow power losses;
* Decrease of power consumption by 3-4 times or more;
* Increased functionality of the equipment;
* Increased service life of motor.
The frequency converter (VFD, Variable Frequency Drive) is incorporated for motor speed control. This allows precise air
flow adjustment so that the Metra Separator is accurately tuned for operation with any material.
The separation chamber is equipped with baffles for the output trays. Using the baffles, the operator can easily direct the
grain flow to the desired trays and improve the quality of grading by means of precise settings.
4.2. Models with CDC (Cyclone Dust Collector):
The grain cleaner Metra ADS models with CDC (Cyclone Dust Collector) provide air cleaning during operation. Impurities,
dust, chaff and non-grain waste is removed through the special waste trays.
The air is flown inside the Metra Separator in a closed circuit, thus the air is purified effectively inside the system. No
additional cyclones or any other aspiration equipment is required.
