As the first batch of raw coal successfully reached the 50-meter-high warehouse roof and entered the silo, it marked that our coal coke silo project was successfully put into operation, and it also marked that we had successfully built the coal coke silo group with the top reserves in Asia. It is reported that the coal coke silo project realized the direct unloading of raw coal and coke at the wharf, and finally transported to the silo for airtight storage through conveyors, unloading trolleys, transfer stations and other processes. To solve the problems of dust pollution, raw coal loss and other problems, realize zero dust emission, zero loss of materials, and all "particles return to the warehouse". At present, we have built more than 170 coal coke silos, with a total coke and coal reserves of more than 1.4 million tons, and the construction scale ranks among the top in Asia.
