Working principle

       

      Being a vertical mill, the column mill adopts a grinding principle of continuous and repeated rolling of material bed under medium speed and medium pressure, which is characterized by simple and reliable structure and extremely low failure rate. The motion of the upper structure of the machine transmits to the main shaft, making the latter resolving, which makes the rollers connected to the shaft resolve in the inner conic lining(the gap between the rollers and the lining plate is adjustable but without contact). The material is fed from the machine upper structure and forms a material bed between the rollers and the lining by its own weight and the upper material pushing function, and is pulverized by repeated rolling of the rollers, and finally is automatically discharged from the lower part of the mill. Because the rollers only make regular revolution and rotation, the force exerting on the material bed mainly comes from the pressure produced from flexible devices, thus the ernergy consumption and abrasion caused by the shocking between the rollers and lining plate are avoided. Therefore, compared with other grinding equipments, it is quite remarkable for column mill to save energy and reduce consumption.. In addition to its applications in fine grinding, currently it is also the best equipment for coarse grinding and ultra-fine grinding.

Performance and characteristics 

Economized electricity consumption: economizing electricity by 50-60% than ball mill, and economizing electricity by 30-40% than vibrating mill and Raymond mill.Small atrasion: adopting a grinding principle of material bed rolling and high alloy abrasion-resistant material, the grinding body(worn parts) has a long working life.High productivity: the processing capability is large and the working efficiency is high, applicable to medium and large-scale grinding and pulverizing in each sector of industry.Wide applications: the gap between the rollers and the lining plate is adjustable, but never contact or collide, the temperature increase during grinding process is small(<70 degree), thus applicalbe not only in fine grinding technique, but also in ultra-fine pulverzing technique. It is highly adaptable for materials that are hard to grind.Small demension: simple installation, small cccupation of land area, and economized investment in civil engineering.Easy operation: simple and scientific structure, reliable performance, easy and convenient operation and maintenance, operation rate reaches more than 90%.Environmentally friendly: noise less than 90dB, basically no flying dust and vibration.
