The working state of ball mill is influenced by types of ball mill and the grinding conditions. Different types of ball mill should be chosen due to different grinding conditions. Now, the relationship between types of ball mill and grinding conditions will be introduced briefly below.
The type of ball mill is related to the water content of ore. For the type of MQG dry grid ball mill, water content of ore should be controlled strictly before grinding. High water content would easily led to the solidarity of ore, blocking the grid linder of ball mill, and making difficult for ball mill to discharge.
The type of ball mill is related to the optimal speed of ball mill. The optimal speed of GZMg、MQG grid ball mill is higher than that of GZM、MQY overflow ball mill. The reason is that steel balls in grid ball mill mainly do parabolic drop motion, but steel balls in overflow ball mill do diarrhea drop motion. Therefore, the speed of grid ball mill is higher than that of overflow ball mill.
The type of ball mill is related to the filling rates of steel balls and its size. GZMg、MQG grid ball mills have grid linder in discharge port, which blocks the discharge of steel balls. Therefore, the filling rates of steel balls are higher and the size of steel ball is smaller in grid ball mill.
The type of ball mill is related to the ship of liner. It is wave shape liner that raise stell balls and ore to a certain height, which contributes to saving energy. GZMg and MQG grid ball mill that are coarse grinding equipment adopt the wave shape liner. Steel balls do diarrhea drop motion due to smoothing shape liner, which helps to the grinding effect and increase the fineness of grinding. Therefore, GZM and MQY overflow ball mill that are fine grinding equipment always adopt the smooth shape liner.
The type of ball mill is related to the speed of ore feeding. The efficiency of GZMg and MQG grid ball mill is higher than that of GZM, MQY overflow ball mill. Therefore, the former has higher speed of feeding.
Xinhai mining machine provides customers with practical suggestions for selecting types of ball mill. Xin Hai also provides the best grinding conditions, and the most suitable type and specification of ball mills, which are higher efficiency of work, more reliable and stable operation.
