Description

technical field [0001] The invention relates to the field of grinding engineering machinery, in particular to a ball mill. Background technique [0002] The ball mill is the key equipment for crushing and grinding after the raw materials are crushed. It is the most important high-fine grinding production equipment in industrial production enterprises. The speed of the ball mill is one of the key factors determining the grinding efficiency. At present, the speed of the ball mill is roughly calculated based on factors such as the diameter of the ball mill and the centrifugal force formula. And the speed of the ball mill remains constant throughout a working cycle. Inside the ball mill is a mixture of ball stones, raw materials, and water. During the continuous working process of the ball mill, as the fineness of raw materials increases, the degree of mixing of raw materials and water becomes more and more sufficient, and more and more solid raw materials are ground. More an...

Problems solved by technology

Therefore, when the ball mill always maintains a rotating speed, the movement state of the ball stone inside the ball mill only realizes the best working process within a certain period of time. The speed of the ball mill cannot be adjusted in time according to the condition of the raw materials inside the ball mill. optimal in real time
