Feldspar Grinding Mill Machine is the new type mining equipment for making micro powders fine powderswhich is widely applied in the industries of metallurgy mining chemistry cement construction refractory materials ceramics and so onThe purpose of the micro powder grinding millis for superfine grinding materials with hardness less than 9 in Mohs scale and humidity less than 6 percent such as kaolin limestone calcite marble talcum barite gypsum dolomite bentonite mud mica pyrophyllite sepiolite carbon black diatomite graphite alunite fluorite potassium feldspar phosphorite pigment up to 200 kinds

Production line consists of  hammer crusher bucket elevator storage hopper vibrating feeder main unit inverter classifier cyclone collector pulse deduster system high pressure positive blower air compressors and electrical control systems

Working Principle of micro powder grinding mill

When Feldspar Grinding Mill Machine is at work all the grinding rollers are rolling in the ring and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed crushed and grinded by the rollers

The highpressure air blower constantly inhales air within the grinding mill and in turn  the airflow with crushed materials are brought to the classifier whose highspeed impeller will screen the airflow the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector Most of the qualified powders will fall and exit from the discharging valve at the bottom a small proportion of the fine powders with airflow moves to the dust cleaner and clings to the surface of the filter bags At the same time the fine powders clinging to the surface fall down by the sudden vibration of the filter bags which is caused by the instantly ejected highpressure gas controlled by the pulse valve The materials from the above two lots are sent by the conveyor at the bottom to get finished powders packed In addition filtered clean air will be emitted from the air outlet of muffler in the end
