选煤厂由于原煤水分大,粉粒多,经常造成原煤仓堵塞、粘壁、起拱,致使煤仓容量减小,卸煤不畅,甚至煤流流不出来。所以有的选煤厂出现“原煤仓一拉就满,一洗就空”的不正常现象,严重影响生产正常运转。 Coal preparation plant due to the large coal moisture, powder and more often lead to the original coal warehouse blockage, sticky walls, arch, resulting in reduced coal storage capacity, unloading coal poor, and even coal flow out. Therefore, some coal preparation plants appear abnormalities such as “a coal warehouse is full and a wash is empty,” seriously affecting the normal operation of production.
