Production capacity analysis of ball mill and rod mill

Production capacity analysis of ball mill and rod mill

Both ball mill and rod mill are important mining mills, and their production capacity is related to the following factors: ore grindability, particle size of feed ore and final product, type and size of grinding machine, shape of liner, The shape, size, proportion, hardness and density of the grinding medium, the number of revolutions of the mill, the filling rate of the grinding medium, the grinding concentration, the amount of sand returned and the working efficiency of the classification equipment, etc. Since there are many factors affecting the production capacity of the grinding machine, and the changes are large, there is no theoretical formula for accurately calculating the production capacity of the grinding machine. Therefore, the production capacity of the grinding machine is generally calculated based on empirical formulas and approximate methods. There are two commonly used calculation methods: the calculation method of the unit production capacity of the grinding machine based on the ore feed (also called the volume calculation method) and the grinding power calculation method. The volume calculation method is commonly used in our country, which is more convenient to calculate.
