The development of vertical mill

The first vertical mill is developed and manufactured by Germany in 1920s. It’s said that the first vertical works like grain grinding mill. Having overcome many disadvantage of ball mill, vertical mill has high efficiency and low power consumption. The roller compacted materials directly onto the millstone, so power consumption is low. Compared with ball mill, it saves energy consumption by 20% ~ 30%. Besides, vertical mill has many advantages like high drying ability, simple and reliable operation, the stability of product quality, occupation area, maintenance convenience, low cost and low noise.

In recent years, with the rapid development the R&D technology of grinding machinery, the technology of abroad vertical mill manufacturers has become very mature, and its technical advantages have become increasingly prominent. In this situation, the domestic grinding mill enterprises learn from the foreign successful experience, carry out major technological innovation and also re-launched their own new vertical mills with patented technologies. The vertical mill is gradually accepted in the domestic cement, power, chemical industry etc. become the industry preferred grinding equipment.
