This machine is mainly used to pulverize various nonflammable and unexplosive materials less than 9.3-scale Moh’s hardness and 6% humidity, in the industries of glass, rubber, pesticide, ceramic, paint, phosphate fertilizer and paper-making etc. These materials include pencil stone. barite calcite, limestone, marble, manganese are, iron ore, clay, feldspar, bolus alba, bentonite and so on.
This machine has high yield.wide application，small power consumption，easy operation and steady performance, which make it become the ideal equipment of pulverizing industry.
After being crushed into shivers less than 20mm, the materials are carried into store bucket by bucket-lifter then into main frame by electro-vibrating feeder at fixed quantity for grinding. The five grinding roller devices that are hung on star rack in main frame rotate around center axis and the grinding roller makes rotation around grinding roller and around axis at the same time. with the effect of the centrifugal force, grinding roller sways outward and impacts grinding ring to place the grinding materials on shovel between them and achieve the crushing and grinding effects by the rolling and crushing of grinding roller, The crushed powder is blown into the analytic engine on the upper of main frame by the air current of air blower for divisional screening. The thicker than fine standard will fall into main frame for regrinding and the qualified far fine standard will enter the large cyclone collector by the wind current and then was discharged through discharge pipe and becomes finished product. The purified air current blows into air blower through the pipe on the upper of large cyclone collector. The wind is circular and the air current in the blows under pipeline negative pressure except that the air current from air blow to pulverizing room is under positive pressure.so the healthy conditions is good in the workshop.
As the water in materials is heated by grinding to vapor into gas.the air that is discharged into air pipe at the flange junctions and feed inlet results in the growth of air volume in circular air current. This increased air volume through the remaining air pipe between air blower and main frame makes the powder by air current with small box cyclone collector to be discharged by the dust collector without collection.at the same time, the air collects powder. The dust collecting system is environment-friendly and has no pollution.
This machine consists of main frame, air blower, bucket elevator, electro-vibrating feeder, store bucket,jaw crusher, pipe system, cyclone collector, electric control cabinet, etc.
1. Smooth operation, small occupation area. Raymond mill host transmission device adopts sealed gear box and a belt wheel, smooth transmission, and the vertical structure, space saving, convenient operation.
2. Large capacity, high rate. Through screening a molding material grinding, save the production cost, compared with other milling equipment, its 2-screening rate high, 2-screening rate as high as 99%.
3. Simple operation, wide application range. The electrical system of Raymond Mill centralized control, mill shop basically no work can be realized, the finished product size 80 - 325 mesh range adjusted.
4. Structure optimization, low maintenance cost. The important parts are made of high quality casting and molding manufacture, high durability, convenient replacement of wearing parts.
