Several factors affect the efficiency of a ball mill for cement grinding. In this article, we shall be looking at some of these factors that have been proven to influence grinding efficiency: Mill Geometry And Speed. According to Bond 1954 , the grinding efficiency of a mill depends on the ball mill diameter, size of the media and mill speed.
Heterogeneous ores tend to result in selective grinding, for easily grinding particles usually are comminuted in rough grinding, while the rest wear-resistant particles will decrease ball mill capacity. Therefore, large feeding sizes will affect ball mill efficiency. 3. Mineral slurry density: in wet grinding, material pass time, production ...
Add some chemical reagent to change the grinding effect and promote the grinding efficiency during the grinding stage; Change the grindability of the ore, such as heating the minerals, change the mechanical properties of the ore, reduce the hardness of the ore. 2. More crushing and less grinding to reduce the feed size into mill
The grinding surface will also increase. All these will increase grinding efficiency. 4. Based on main mill structure and parameters, strengthen some critical components such as foundation, central axis rack, relieving tool, star rack, gearbox, etc , reinforce cement foundation, improve stability of damping device, blower box, shell.
The grinding efficiency of ball mill is low, the treatment capacity is low, the production energy consumption is high, the product fineness is unstable and so on, which are the problems that most concentrators will encounter. How to effectively improve the grinding efficiency of ball mill is an important problem.
To improve the vertical slag mill efficiency by . In the vertical slag mill, maintaining the stable material bed is the basis of the vertical mill grinding, and it is also the key to the normal operation of the mill. Therefore, we can start from the perspective of stabilizing the bed to improve the efficiency of the mill. Get Price
The grinding efficiency is reflected in the processing capacity of the mill and the fineness of the grinding ore. Large diameter steel ball help reduces grinding time thus improves grinding efficiency, in addition, putting some small steel ball to control the particle fineness effectively.
The first two Grinding Efficiency Measurement examples are given to show how to calculate Wio and Wioc for single stage ball mills. Figure 1. The first example is a comparison of two parallel mills from a daily operating report. Mill size 5.03m x 6.1m 16.5′ x 20′ with a ID of 16′ . This example shows that Mill 2 is slightly more efficient than Mill 1 even though it has a higher power ...
