Detailed Description of Laboratory Roller Mill:

  Laboratory Roller Mill is a new kind of micro powder processing equipment, which is invented through more than twenty times experiments and improvements, and based on twenty years of mill manufacture experience while absorbing advanced international machine manufacture techniques. Micro powder mill is mainly used in processing non-inflammable, non-explosive, brittle material with hardness below six mhos, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, pyrophyllite, barite, gypsum, alunite, granite, fluorite, phosphate rock, kalium ore, float stone, more than 200 kinds of materials. 

Working Principle of Laboratory Roller Mill:

Firstly, raw material is crushed by jaw crusher to the size required, then the crushed materials are elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder, evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between ring and roller to accomplish the grind.

After this, the ground stuff are carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The set’s airflow system is closely sealed up and circulated under condition of negative and positive pressure.

The Main Features of Laboratory Roller Mill:

1, compared with the scope of a larger jet mill.
2, compared with other similar mills, grinding roller pressure on the material under high pressure spring to improve 800-1200Kg.
3, energy saving. Yield and fineness in the same case, the system energy consumption is only one-third of air current mill.
4, low investment, high returns. Yield and fineness in the same circumstances, the price of jet mill is only one-eighth.
5, feed particle size of the expected average size of up to 6.5um disposable ultra-fine powder.
6, overlapping multi-pole sealed grinding unit, good sealing performance.
7, dust removal fully meet the national dust discharge standard.
