Based on middlings can be further dissociated after crushing,it takes a theoretical analysis about crushing and dissociation of middlings and makes suitable coal separation method and process flow in this paper.According to the calculations of product recovery rate,investment,operation cost and economic benefits of this system,high-ash clean coal recovery rate and annual output will be theoretically increased by 0.28%and 8400 tons with annual gross benefits increased by 5.17 million Yuan after crushing and disassociation process of middlings is added,which implements the principle of"eating up and squeezing dry",brings remarkable economic growth and provides reference value to nearby coal preparation plants with similar conditions who are considering this process.
