Application of compound crusher in middling coal re-separation technology
In order to make full use of the scarce resource of coking coal,key technologies such as coking coal dissociation,separation and recovery have been studied.Crushing for dissociation is the premise of separation and recovery.However,at present,the crushing equipment used in the coal preparation plant has a small crushing ratio,which requires multiple crushing and even grinding to realize the dissociation of middling coal.Combined with the characteristics of impact crusher,hammer crusher and ring hammer crusher,therefore,the compound crusher can deeply crush and dissociate the middling coal in coking coal preparation plant,and the dissociation can be achieved by one crushing.Low energy consumption and low investment create conditions for fully recovering the scarce resource of coking coal.
