The coal washing filter equipment used in Yongchuan Washing Plant was aging, with low technology content, high coal washing cost and poor recovery rate of clean coal. In mid-April this year, the plant raised 1 million yuan of self-raised funds and introduced the nation's leading automatic touch screen filter press automatic control system. The cycle time of coal washing was shortened by 12 minutes per cycle, and the processing capacity per unit hour was increased by 25%. The original operation of 4 people per shift was reduced to 1 person, and the operation was simple, saving time and effort. The modified filter press can be automatically controlled according to the change of coal quality and the amount of washing, thereby greatly improving the efficiency of coal washing.
Swing-arm Type Telescopic Belt Conveyor
The manoeuvrable roller table diversion located at the bottom of the conveyor structure is a bouncing device and outputs product from the sorter as the roller table spirals up to the left or right. When tracking in different windows, the sorting rate is nearly 7500 pieces/h. A disadvantage of line sorters is that they often require very complex confluence stations to guide products efficiently into the system. The merging station directs products from several conveyor belts into one main conveyor line and creates fixed or different gaps between the products to force them into the sorter, depending on the type of sorting. Ring Sorter The Ring Sorter costs more than the Linear Sorter, but it offers better functionality and flexibility than the Linear Sorter. It can achieve very high sorting speeds, with a design speed of up to 40,000 pieces/h and several hundreds of distribution lines.
