Working Principles of Mini Mill (Laboratory Sand Mill)

After feeding a material into the grinding chamber via the opening of feed end on the right of sand mill, and then cover it. The material in the chamber charged with fine mill ball will be powdered under the action of a stator and a atwirl rotor made from wearable ceramic; the material will be circulated via an afferent duct between top and bottom of the chamber because of the air self absorption effect produced in the system, which enables the efficiency of size reduction, finally the ground material will be discharged from the opening of feed end.

Performance and Characteristics of Mini Mill (Laboratory Sand Mill)

1. Feeding and discharging material are easy because of the compact rotating drum.
2. The integration of grinding chamber and drum enable cycling mill without a pump.
3. The grinding medium can be fine mill ball, whose diameter can be 0.5mm.
4. It is driven by AC of 220V in lab, and also suitable for explosive hazardous material by aerodynamics.
5. The compact and totally sealed micro-grinding made of stainless iron featured by fine workmanship, full automatic control easy operation and dismantlement.
6. The speed of rotor is controlled by a frequency transducer and material can be powdered into sub-nanometer.
7. Exact reproducibility of tests.

Application Fields of Mini Mill (Laboratory Sand Mill)

LHE Sand Mill is very suitable for grinding test of small-sample in laboratory and the first choice for powder research and new product development.
