1 Brief introduction of vertical roller grinding mill

Vertical roller grinding mill is a new large scale power mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. Vertical roller grinding mill is an ideal equipment which have integrated the crushing, dry, powder grinding, and graded deliver into a single whole .And now  the vertical mill has found its extensive application in the field of Cement, electric power, metallurgy, chemical industry, non-metallic mineral, etc. Vertical roller grinding mill is mainly used to grind the materials with block, and particle size to the required powder materials.Vertical roller mill is a necessary equipment for the high production of mineral powder in the non-mental mine industry and large scale powder making in many other industries.

2 Advantages of vertical roller grinding mill

 1.Three-dimensional structure

2.The screen-passing rate can reach 99%
3.Lower oil and power consumption
4. Unique design more effective than traditional machines
5.The transmission device of mainframe adopts airtight gear case and zonal wheel
6. Centralized control for the electric system, convenient to operate 
7. Higher productivity and capacity utilization 
8. Meet the latest environmental standard

3 Working principle of vertical roller grinding mill

Raw material which has been crushed to the size specified is elevated into a hopper from which the stuff is loaded. And then through the vibrating feeder ,the materials will transferred evenly and continuously into the raymond mill grinding chamber for powder-processing. After this,the ground stuff is carried by the air from the blower into the classifer for regrinding.The set's airflow system is closely sealed up and circulated under the condition of negative and positive pressure. The raymond mill is driven by rotation of the central axle through decelerator ,with the up end of the axle connecting to a quincunx-rack upon which the grinding equipment is fixed. The whole set equipment turns together with the axle along the grinding ring while the rollers rotate driven by the fractional force .A set of shovel are installed at the lower end of the quincunx-rack.While turning together with the rollers ,the shovels shed the stuff onto the gap between the rollers and the ring ,and that's where the stuff layer forms .The rotating rollers ,while turning together with the ring ,grind the stuff layer into powder. The turning speed of the impeller can be adjusted to the requirement of the fineness of powder products .Raymond mill plays an important role in ensuring the function of the grinder . As the high-speed revolving air current mixed with ground stuff is flown into the cyclone-collector ,the ground stuff is separated from the air-current.
