Large output and high production efficiency
Widely used in calcium carbonate (calcite, marble, limestone, chalk), barite, kaolin, dolomite, magnesite, alumina, superfine cement, slag, steel slag and other industries.
Features and Advantages:
Working Principle:
Roller mills(micro powder roller mill,fine roller mill,ring roller mill,roller grinding machine,automatic roller mill,three/four roller/rolling mill) are mills that use cylindrical rollers, either in opposing pairs or against flat plates, to crush or grind various materials, such as grain, ore, gravel, plastic, and others. Roller grain mills are an alternative to traditional millstone arrangements in gristmills. Roller mills for rock complement other types of mills, such as ball mills and hammermills, in such industries as the mining and processing of ore and construction aggregate; cement milling; and recycling.
Transmission device connects with main shaft. The top of shaft connects with rotor structure. The rotor structure has peripheral shaft. Peripheral shaft is installed with roller. When the main shaft starts to rotate, peripheral shaft rotates too, which would make the rollers revolve around main shaft and also rotate round peripheral shaft. The roller would create strong centrifugal force during the rotation and revolving, and grind material with stator. The ground material would fall down to the distribution plate. The distribution plate and the main shaft would rotate at the same time, and bring material to the round ring. Under negative pressure, it would go along the distribution ring to the classifier chamber. Qualified fine powder would go through the classifier wheel and into the collector, while coarse powder would fall down back to the milling chamber for further grinding.
ALPA is a rolling mill manufacturer that produces various types of mills.

Impact mill
High efficiency, has two milling effects of impact and grind, large milling ratio, simple structure, stable operation, suitable for milling medium-soft hard materials.
Jet mill
Uses the high speed turbulence airflow generated by compressed air or superheated steam as milling power. Impact extrusion, friction and shear between the particles or between the particles and the fixed plate occur, so as to achieve milling.
Ball mill + Classifying
The ball mill and classification production line refers to a complete set of milling system composed of Ball mill, cyclone, dust collector and fan.
