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 ore, 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.
1. efficient, energy-saving: high pressure spring compression device makes the roller pressure increase, mill yield, suitable material in a wider range.
2. long life of wearing parts: roller grinding device with mechanical air resistance type international advanced seal plus chongdieshi multistage sealing, good sealing performance, reduce maintenance costs, extend equipment life.
3. high safety and reliability :in the mill chamber without rolling bearings, without screws, so there is no bearings and seals the vulnerability problem does not exist screw loose to make damage to the equipment.
4. The effect of fine material sorting, forming once time: improved turbine blade analysis machine, with high density, flow resistance, powder fineness and yield increase, analysis of variable frequency speed regulation machine, more accurate, more energy, better fine material separation effect. A high degree of automation.
5. environmental protection, clean: with soft connection and with rubber pads and other measures can effectively avoid the influence of shock, vibration of the grinding cavity analysis machine, and improve the accuracy of analysis. At the same time, reduce noise, improve the working environment.
The HGM Grinding mill consists of main frame, air blower, bucket elevator, electro-vibrating feeder, store bucket, jaw crusher, pipe system, cyclone collector, electric control cabinet, etc.
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 for 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.
