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 .

Bond's law. Used to predict the energy requirements for size reduction 26 Rittinger's law(1867) Rittinger's Law suggests that energy required in a size reduction process is proportional to the new surface area produced. where, E = energy required for size reduction KR = Rittinger's constant Si = initial specific surface area Sn = final specific surface area Appliion: It is most ...

This paper examines potential relationships between UCS and Bond Work Index values (crushing, rod mill and ball mill). Data from 11 mines loed around the world is analysed for correlations between UCS and various Wi values. Introduction Need to accurately predict future mine and mill production rates requires a knowledge of ore grindability well in advance of .

Bond (1952) proposed the 'Third Law' of grinding. The Third Law states that the net energy required in comminution is propor tional to the total length of the new cracks formed. The resulting equation is: Relationships between comminution energy and product size for a magnetite ore by A. Jankovic*, H. Dundar†, and R. Mehta‡ Synopsis

Bond's law, which assumes that ... For comminution of finer particle size ranges (20mm > P 80 > 30 μm) machines like the ball mill, vertical roller mill, hammer mill, roller press or high compression roller mill, vibration mill, jet mill and others are used. For yet finer grind sizes (sometimes referred to as "ultrafine grinding"), specialist mills such as the IsaMill are used. .

02/06/2017 · Bond's Law states that the total work input represented by a given weight of crushed product is inversely proportional to the square root of the diameter of the product particles. Bond's Law can be written as: E = E i (100/L 2) 1/2 [1 (1/q 1/2)] Where: E=Energy, L 1 = initial length, L 2 =reduced length, E i is defined as the amount of energy required to reduce .

Bond's law, which assumes that the total work useful in breakage is inversely proportional to the square root of the diameter of the product particles, [implying] theoretically that the work input varies as the length of the new cracks made in breakage.

Clarifiion: There are three physical laws that describe the energy required for size reduction. They are the Bond's Law, Rittinger's Law, and Kick's Law. The size reduction is a unit operation where a set of conditions are performed until the size specified is achieved. 2. Which mechanism is utilized when particle concussion by a single rigid force? a) Impact b) Compression c) Shear .

Energy Required to Crush Coarse Materials according to Bond's Law calculates the energy needed to crush raw materials such that they pass through a sieve aperture of lower diameter and is represented as E = W i *((100/ d1)^(100/ d2)^) or Energy per unit mass of feed = Work Index *((100/ Feed Diameter)^(100/ Output Diameter)^). Work Index always .
