Ball mill is also called coal mill or tube mill, which consisted of large tank tube, a large and a small wheel gears, a bearing, transmission device and electric motor. When the ball mill operating, these parts will produce noises, but they are different from each other and the primary and secondary status of noise source is different. On the condition that the enlarging of ball mill market in the mining ore dressing equipment nowadays, so many ball mill manufacturers are emerging, which providing more decisions for ore dressing factories. While, more decision, less knowledge to choose which one, because they consider that there is none that they need.
The noises produced by the energy-saving ball are generated by the impacting and grinding between steel ball, materials and scare board. The noise belongs to the mechanical noise and radiate outside along with the surface of the tank. The noise can be different when the size and quantity of the crushing material is different, even the same type energy-saving ball mill in the same sand making line.
Hongxing Machinery’s sound source analysis on the energy-saving ball mill units indicates that the large tank tube is main source of noise and gears, bearing and the transmission device and electric motor are minor sources of noise relatively. Considering the acoustical power, the large tank tube is main device for its radiant acoustical power and other parts produce lower acoustical power. The balance can be different in a level.
