Raymond Mühle / Raymond Grinder

Raymond Mill produced by our company is mainly used to grind non-inflammable and non-explosive materials with Mohs hardness below 7 and moisture content below 6% such as barite, calcite, potash feldspar, talcum, marble, limestone, ceramic, glass, etc for ultra-fine powder processing of 280 materials Raymond grinder can be used in mining, chemical industry, construction materials, metallurgy and so on. The granularity of the final products can be adjusted freely from 100 mesh to 425 mesh. Working Principle Firstly, raw material is crushed by jaw crusher to the size required, then 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 rotate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between the ring and rollers to accomplish the grinding.After grinding, the rough materials will be recycled by the air from the fan back into the grinding chamber for regrinding and the fine powders are blew into the cyclone and poured out through the output-powder pipe as the final products.Technical Parameters typeroller no.roller size(L×H)(mm)ringinside diameter and height (mm)max.feed size(mm)output granular(mm)capacity (t/h)main motor power(kw)weight (t)overall dimension(mm)3R21153φ210×150630×150150.2-0.0440.4-1.6153.64500×2800×58003R26153φ260×150780×150200.2-0.0440.8-2.518.54.25650×3305×59503R27153φ270×150830×150200.2-0.0440.9-2.8224.85600×3400×59004R30164φ300×160880×160200.2-0.0441.2-3.5308.56500×4100×52004R32164φ320×160970×160250.2-0.0441.8-4.537159900×5800×10580
