FH Series ring roller mill
▎Product Introduction>>
Ring roller mill, also known as roller press mill (abacus mill), is a grinding process that involves multiple layers of ring rollers for crushing, impact, and grinding.
The raw materials are quantitatively fed into the crushing chamber, and under the action of centrifugal force, they scatter towards the periphery of the ring roller and fall into the rolling path of the grinding ring. They are stamped, rolled, and ground by the grinding roller and then crushed. After being crushed in the first layer, the materials fall into the second and third layers. After being crushed in the third layer, they are thrown out by the shaking plate and sucked into the classifier by the negative pressure of the induced draft fan. The coarse particles are sorted and returned to the classifier for re grinding, Fine powder enters the cyclone collector or bag filter with negative pressure airflow to collect and separate gas and solid. The material is discharged from the discharge valve to form the finished product, and the air is purified by the dust collector and discharged through the fan and muffler.
Widely used for high-precision grinding of various non-metallic minerals such as talc, calcite, calcium carbonate, dolomite, potassium feldspar, bentonite, kaolin, graphite, carbon, etc. with a Mohs hardness of less than 6 levels and a humidity of less than 7%.
▎Structural Characteristics>>
A. Roller crushing and multi-layer rolling are suitable for mineral powder materials with a Mohs hardness of less than 6 and a humidity of less than 7%, widely replacing Raymond grinding.
B. Simplified structure, exquisite materials, more durable and easy to use, can be applied in high fineness and large output.
