In order to improve the flexibility of the crushing system in the coal preparation plant,solve the problems of unsold medium-sized coal and poor economic benefits,the crushing system of medium-sized coal in the coal preparation plant has been optimized and transformed.On the basis of the original lump coal crushing system in the coal preparation plant,a set of medium-sized coal crushing system has been added as a bypass for use.This system will not affect the original washing process of the coal preparation plant,and can mix the crushed medium-sized coal with the final coal and small coal for sale.This paper studied the optimization plan and equipment used for the process transformation of the medium-sized coal crushing system,and compared and analyzed the economic benefits of the coal preparation plant before and after the process optimization transformation of the medium-sized coal crushing system.After the process transformation and optimization of the medium-sized coal crushing system,the economic benefits increased by about 1.518×106 yuan/a,while improving the flexibility of the crushing system in the coal preparation plant.
