good quality raymond mill for grinding stone, barite, calcite,
limestone, rock phosphate,marble,dolomite,gypsum
Applications of Raymond roller mill:
Mainly used for the high fine powder processing of over 280
varieties of non flammable and non explosive materials with the
Mohs hardness of no more than 9.3, and humidity of below 6%, such
as barite, calcite, feldspar, talc, marble, limestone, dolomite,
fluorite, lime, activated clay, activated carbon, kaolin, cement,
phosphate rock, gypsum, glass, and insulation materials, in such
industries as mine, chemical and construction.
Working Principles of Raymond roller mill:
Firstly, raw material is crushed by jaw crusher to the required
size, which is lifted up to the hopper.
Secondly, the raw material goes into the grinding chamber through
the electro magnetic vibrating feeder at an even rate.
Thirdly, the raw material lifted by the shovel is ground into
powder between the ring and roller.
Fourthly, the powder is blown up to the cyclone collector through
the classifier, which will be collected through the discharging
The unneeded powder, which cannot go through the classifier, will
be reground into the needed powder.
Dimensional structure, small floor area. strong performance become
a complete set with a production system independently.
Even fineness of finished powder and qualified screening rate of
99%, which is difficult to reach for other milling equipment.
The transmission device of the main engine adopts a sealed gear box
and pulley, with smooth transmission and reliable operation.
Electrical system adopts centralized control, and the grinding
workshop can realize unmanned operation with easy maintenance.
