Range of application of the device
Long-term operation
This laboratory device is designed for eight-hour single-shift operation
with a duty cycle of 30 %.
This device may not be used as a production machine nor is it
intended for continuous operation.
6.2 Principle of Operation
The grinding and deagglomeration in the SR 300 is achieved by impact, collision and shearing
effects. The feed material passes through the feed hopper into the grinding chamber where it is
comminuted between the rotor and the selected ring sieve or sieve and grinding insert. As soon
as the grinding material is smaller than the mesh size of the sieve, it enters the collecting
receptacle.
