Bond Work Index. In the 1930s through early 1950s, Bond developed a new theoryminution 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 theoryminution, counting

Calculations involving Bonds work index are generally divided into steps total energy consumed and 2 size distribution of fragments. In a study on crushing and grinding, fracture toughness has been taken as a key index similar to the Bond Work Index. Due to many cracks dealt with, rock fragmentation is aplicated and difficult fracture problem. To achieve a good fragmentation
1961. Crushing and Grinding Calculations Part I and II, British Chemical Engineering, Vol 6., Nos 6 and 8. A Bond Ball Mill Work Index test may be required for the design of a new mineral processing plant. Where possible, it is carried out on a sample of ore that is typical of the proposed feed to the plant. The BBMWI is then used in the design calculations of the new grinding circuit
01/01/2016· 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 new feed, that is, the original feed plus
The ore passes through primary and secondary crushing and grinding. The final product is 80 passing 270 mesh. Bond has published a Wi for taconite of 14.87 1961. This value is used in these base case calculations. Table 1 shows the feed and product size, the calculated total energy input, and the energy cost for each unit operation. The explosive cost is based on the powder factor of 0.33

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting.minution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand e.g., via a hand crank, working animal e.g., horse mill, wind or water .

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. The Bond Abrasion Test determines the Abrasion Index, which is used to determine steel media

The grinding action is induced by relative motion between the particles of media the rods, balls or pebbles. This motion can be characterized as collision with breakage induced primarily by impact or as rolling with breakage induced primarily by crushing and attrition. In autogenous grinding machines fracture of the media particles also occurs by both impact self breakage and attrition
