Roymond Grinder

1.The machine is widely used. 2.High efficiency and multi-function. 3.Little investment and stable quality.

1,Use and applicable scope:    The machine is widely used for barites, calcite, potassium feldspar, talc, marble, limestone, dolomite, jade-like stone stone, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, thermal insulation materials mok's hardness is not more than 7 magnitude, humidity in the below 6% inflammable and explosive of mineral, chemical, construction and other industries 300 multiple materials of high fine powder processing, R type Raymond mill finished granularity 80-325 mesh range to arbitrarily regulate, and partial material tiptop 600 mesh.

2,The structure and working principles:(a)The host by spiral, shovel knife, grinding roll, grinding ring, cover shell composition crushing chamber. Fixed hanger in upper center axis. Pylons on three grinding roll axis rotation, revolution, while by rotating centrifugal role tightly compressed grinding ring rolling, the shovel garden knife scooping up materials, send in grinding roll grinding ring between crushing.(b) fan will wind into the host inside, with a shattering of materials to be delivered through the host fineness analyzer for top fine anthology. Coarse material return crushing chambezr heavy grinding, Finished product currents into large whirlwind separator, and air separation back out, separating out air duct into the platoon fan and under negative pressure, excess air circulating by air blower and the exhaust duct between hosts into environmental separator, purifying.
