ertical roller mill Basic introduction                                          

Vertical roller mill is referred to as the vertical mill, one for cement raw materials, cement clinker, slag and cinder grinding processing, has the characteristics of simple structure, low cost of manufacture and use. Which comprises a machine body, grinding disc device and a transmission device, a centering device determined the gyration center is arranged between the device body and the grinding disc, a rotary guide rail is fixedly arranged at the bottom of the grinding disc device, the grinding disc device through the rotary guide rail can be rotatablely supported on the body, disc device and transmission device in a transmission way.Because the transmission device does not bear the weight of the grinding disc and the grinding pressure high axial load, the transmission device can use the universal speed reducer, which has the advantages of compact structure configuration, reliable work, and can shorten the grinding halt time, reduce the equipment use and maintenance cost.

Design principle                                                                        

The main research of grinding wheel, grinding roller curvature effect on the grinding ability,the unit power consumption, to determine the best grinding curvature. Static, dynamic loadstructure analysis and calculation of large parts of the grinding disc seat and the pressureframe of main bearing, determine the optimum pressure frame section size, find the grinding disc seat stress average distribution, the optimal shape for pouring technology, and give full consideration to the effects of heat stress. Research and analysis based, high efficiency combined development and design for MLS3626 vertical mill powder selecting machine. The key consideration powder selecting regional parts and particle motion control, as far as possible to limit the amount of irregular motion appears inside the mill, reduce circulating loadfrom the surface, to improve the grinding efficiency.

Vertical mill is the realization of mass of material grinding processing device using the roller system of large scale, automation advantages compared with ordinary milling machine is large and the operation of equipment. The current domestic market, vertical mill in various powder

Technological process                                                              

Vertical mill according to the humidifying tower and a dust catcher position, a scheme of arrangement of two different, namely three fan system and double fan system. Using a cyclone dust collector for collecting product. This arrangement can reduce the systemnegative pressure and gas through the dust collector capacity. Available electric precipitatorcan also use of bag filter dust removal equipment used as final; the dust collecting device can be an electric dust collector or bag dust collector, a grinding gas directly into the dust collector, the system reduces the number of devices, simplifies system configuration.

Working principle                                                                      

Working principle of vertical roller mill: the motor drives the disc through the speed reducer to rotate, material by air lock feeder from the feed port falls on the disc center, at the same time,the hot air can enter from the air inlet in the mill. As the disc rotates, the material under the action of centrifugal force, move to the edge of the grinding disc, grinding disc is through the annular groove on the grinding roll and grinding, the crushed material in the edge of the grinding disc is wind ring high-speed airflow with, large particles directly onto the disc regrinding, airflow through the upper part of the separator material, in the rotating rotor under the effect of coarse powder from the cone bucket, to re grinding disc, qualified fine powderwith the airflow out mill, through the dust collecting device for collecting, namely product,containing moisture materials were dried with hot air flow in the process of contact, by adjusting the temperature of hot air, can satisfy the different humidity material requirements,so as to achieve the required product moisture. By adjusting the separator, can achieve the required thickness of different products.
