In this paper, the working principle and key equipment of vertical roller mill separate grinding technology is firstly introduced, then the updated technology scheme and application effect of the TRM53.4 and GRM53.4 respectively from Henan Jinrong, Henan Mengdian cement Ltd. are presented. Finally, a conclusion is drawn that the separate grinding technology can increase mill output by 10~20% and decrease electrical power consumption by 15~20%, which provides a good technology scheme for energy-saving and emission-reduction in the cement industry.
1 Introduction
The vertical roller mill is one of the large host units of the new dry cement production process, which adopts the principle of material layer grinding and has been widely used in the cement industry because of its compact structure, strong drying capacity, high grinding efficiency and easy large scale use. The vertical roller mill system and the roller press final grinding system are the mainstream raw material grinding systems. At present, under the same raw material and product fineness conditions, the roller press system usually has a lower power consumption than the vertical...
