The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill ... Many grinding mill manufacturers specify diameter inside the liners whereas others are specified per inside shell diameter. (Subtract 6" to obtain diameter inside liners.) Likewise, a similar confusion surrounds the length of a mill.

As with rod and ball mills liner designs for autogenous and semiautogenous mills have been in a state of flux for a number of years. Operators continually search for optimum designs. Each mill application and each liner material coupled with varying mill diameters will produce a different internal wear pattern.

Modern ball mills consist of two chambers separated by a diaphragm. In the first chamber the steelalloy balls (also described as charge balls or media) are about 90 mm diameter. The mill liners are designed to lift the media as the mill rotates, so the comminution process in the first chamber is dominated by crushing.
Therefore, it is critical to ensure that mills are operated in an optimised mode. As shown in Fig. 1, an optimised mill entails that mill parameters including steel balls, rock and water loadings, the mill speed, and the liner mechanical design, result in grinding mechanism as well as the liner wear life satisfying the economic production requirement [24].

Liners for the Grinders. Liners do much more than just protect a mill's shell, with current research aimed at optimizing liner design and cutting milling costs. The introduction of rotating ball, tube and rod mills into mineral processing in the late 1800s was quickly followed by the realization that continuous operation with abrasive feed ...

Contents hide. 1 What are the important steps to follow? Step #1: Understanding the Ball mill liner. Step #2: Having experts and learned technicians. Step #3: Cleaning the Mill. Step #4: Removal of the old stuff. Step #5: The installation process. Step #7: Final checkup.
Choosing an appropriate type of lining and design in terms of lining material, thickness and profile is vital for optimizing mill throughput and total good lining should wear out, not fall out! grinding costs. Choosing the correct liner material and design ensures that the mill itself is well protected.
Milling management in Mining and Mineral Industries should keep on improving liner design based on operating experience, ore types, good design practice, and also additional data from ball trajectory and DEM simulations. The smallscale trials for evaluating different liner shapes would rather provide important basic information to industrial ...
Section snippets Experimental data. In this paper, the wear evolution of a liner plate in the first chamber of an industrial m diameter cement ball mill, also known as a tube mill, with two chambers is studied on the basis of the experimental data provided by the company Magotteaux International The total length of the mill is equal to m, while the first chamber is only m long.
The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x ...
According to Swart et al. [9], ball mills are mostly used because of their very high size reduction ratio, although they have a very low energy efficiency of about 20%. According to Conger et al. [10], many factors affecting ball mill efficiency include mill design, liner design, mill speed, charge ratio, and grinding media properties.
