In the middle and late November, the coal slime dryer project with the capacity of 1500 ton per day entered the installation and commissioning stage smoothly. Although the recent severe epidemic situation has caused inconvenience to the construction work, our on-site engineering technicians have made real-time adjustments according to the local epidemic prevention and control policies, overcome all difficulties, and accelerated the equipment installation and commissioning progress. At present, the test run procedure has been successfully completed, and follow-up related work is in progress.
