Development and application of dryer crusher for 2 000 t/d dry process production line with wet grinding

In the project of wet to dry process conversion of 2 000 t/d production line of Huzhou Daqiang Cement Plant, NCDRI developed the largest PCH4225 hammer dryer crusher in China. Principle of ensuring the capacity and specification of PCH4225 crusher was introduced in detail as well as the compose and structure characteristic. The crusher has already been put into service now, and the use status is favorable, the heat rate and pressure loss all reach the designed indexes and even precede that of the congener foreign product, gained favorable economic and society benefit.
