All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼" to 1.5". The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition.

> Learning curve - start with very low ball charge and build up over time. Do not let the mill charge run down > Soft oxide ore low charge - high risk of liner damage- can be catastrophic > First set of liners should take ore into account- conservative design > Low feed rates only with low ball charges- use mill trajectory modelling

Figure 5. High–low wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.

Design Method of Ball Mill by Discrete Element Method The grinding rate of gibbsite in tumbling and rocking ball mills using fins was well correlated with the spe-cific impact energy of the balls calculated from Discrete Element Method simulation.

Nov 18, 2008· Summary The Ball Mill is designed to grind materials by turning the cylindrical shell with grinding medium (e.g. steel balls) put in the shell, and has a simple structure and ease of handling. Furthermore, The Ball Mill of a large capacity has been available to a very extensive range of applications in both dry and wet 14. References 1.

The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Ball Mills Steel Ball Mills & Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis.

With more than 100 years of experience in ball mill technology, 's ball mills are designed for long life and minimum maintenance. They grind ores and other materials typically to 35 mesh or finer in a variety of applications, both in open or closed circuits.

The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.

Oct 12, 2017· Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many processes. Various kinds of mills are there with which different material processing takes place.
