the grinding circuit is the largest capital investment of your processing plant. depending on the grindability of your orebody, abrasion will cause a certain amount of deterioration to the steel media and liners in your circuit. the abrasion test will allow you to quantify this and design accordingly.
based on the above considerations for crushing and grinding, the energy consumption for the clinker pre-crushing and ball milling can be estimated using the following bond based model: (9) w = w c + w m as pre-crushing product size p c is equal to the mill feed size f 80 then: (10) w = a f 80 w i 10 p 80-10 f c + 1.3 ∗ 2.44 d 0.2 ∗ r r + (w
in the bond equation, the feed f is the feed to the grinding circuit and the product p is the product from the grinding circuit. in an open circuit, this is straightforward but in a closed circuit mill, where a classifier is installed to return the course fraction to the mill, the work index is based on the work done in reducing the size of the

bond work index. in the 1930s through early 1950s, bond developed a new theory of comminution that introduced an index, called the bond work index, which relates power consumption in crushing and grinding to the feed and product size distribution. his theory and index were introduced in a widely cited 1952 journal article. bond called his theory the "third theory of comminution", counting
