In August 2015, the installation, commissioning, and operation of the Shengli Coal Mine Raw Coal Screening Renovation Project of Wujiu Coal (Group) Co., Ltd. adopted our company's XCG toothed roller screen to replace the linear vibration grading screen in the original factory building. The grading particle size is 30mm, and the processing capacity is 650t/h. The self-cleaning device of the XCG toothed roller screen is particularly suitable for the wet sticky coal quality of Shengli Coal Mine, greatly improving the screening efficiency. After use, the screening effect is very ideal.
