MCD 680B: frequently asked questions
What motor power does the MCD 680B have, and when should I choose the larger motor?
The MCD 680B is sold with a 30 hp or a 40 hp motor: the frame takes either one. For fine grinding with a screen under 1.2 mm, the 30 hp motor is enough, because the limit is the grinding box, not the power; above 1.5 mm, choose the 40 hp motor. Between 1.2 and 1.5 mm, a specialist will recommend the motor.
How much does the MCD 680B weigh and how much space does it need?
With the motor, the MCD 680B weighs 750 kg. It needs a working area of 2.5 m², not counting the cyclone. The full installation, including the cyclone and the bag filter, is 5 m long.
Does the MCD 680B need a concrete base or anchoring to the floor?
No. Thanks to the mill's balancing, it does not need to be anchored to the floor. It must, however, stand on a solid surface free of vibration and away from machines that vibrate.
Is the MCD 680B three-phase? Is a starter included?
Yes, the MCD 680B runs on three-phase power, and the electrical connection must be made by an industrial electrician. The starter is not included; we recommend a soft-starter.
What comes with the MCD 680B?
The MCD 680B leaves the factory assembled, tested and adjusted, and comes with a polyethylene cyclone with tripod, a bag filter housing with filter bags and a feed hopper.
