Pregrinding vertical mill is a high efficient energy saving grinding equipment which can replace present pregrinding or precrushing equipment in cement grinding workshop. Its main function is to pregrind hot clinker. It has advantages of low maintenance cost, low vibration, high operation rate, long life, good suitability, low investment etc., so it will reduce much cost for new build projects. For expansion projects, it has advantages of small area occupation and simple process flow. Kisen KVM-P pregrinding vertical mill has 9 patents (including 2 invention patents), 4 are authorized complete independent intellectual property rights.


 Main technical features:

 through structure optimization, mill dimension is reduced while efficiency not change, so floor area is reduced; apply new wear material to prolong life of grinding roller and table, so operation rate is increased; in order to meet the demand of pregrinding vertical mill to reducer, we cooperated with reducer manufacturer and designed new pregrinding vertical mill reducer with independent intellectual property rights. When it is applied in cement pregrinding, compared with closed-circuit mill system product can be increased 70%~100%, and energy consumption can be saved 20%~30%.
