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.
Finding the right liner design for ball mills will help production immensely. Choosing the correct mill liner will provide lower maintenance costs, decreased downtime, and better outputs. ... All ball mill liners must be very resistant and capable of withstanding high impacts. The milling process uses steel balls to break down the material.

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.

During the last decade numerous protocols have been published using the method of ball milling for synthesis all over the field of organic chemistry. However, compared to other methods leaving their marks on the road to sustainable synthesis ( microwave, ultrasound, ionic liquids) chemistry in ball mills is rather underrepresented in the knowledge of organic chemists.
From the early years of using these mills, the effect of mill liner design on these mechanisms has been recognized (Weston, 1951). There are different criteria to evaluate the liner performance such as liner life, liner consumption, capacity and performance aspects of mill (Parks, 1989). ... For example different positions in a ball mill ...

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 ...
mill depends not only on the operating conditions, mainly the rotation speed and the filling ratio, but also on the liner itself. For this reason, the slightest improvement of the liner design becomes a significant competitive advantage. In general, the liner design depends on its material and its initial shape. Due to the collisions
