Bond Work Index Test Ball Mill. US$ 13,800. The FC Bond Work Index Test Ball Mill was designed by F. C. Bond for use in determining the Bond Index, a measure of grindability and power required for grinding applications. The FC Bond Mills are used in laboratories throughout the world. A copy of Fred C. Bond’s Method of Crushing and Grinding for
6 rods of 1.25“ diameter and 21“ length. 2 rods of 1.75“ diameter and 21“ length. The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.
Bond Crushing Law In Ball Mill; Bond Work Index Formula-Equation Basic EquationsSize Distribution and Exposure RatioEquations For Work Index VariationsWork Index and Crack Energy The basic work index equation is:W = 10 Wi/√P 10 Wi/√F(1)where W is the work input required in kilowatt hours per short ton to grind from 80% passing F microns to 80% passing P microns, and Wi is the work
* Bond F. C., “Crushing Tests by Pressure and Impact”, Trans AIME, Vol 169, 1947, pp 58-66. Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bond’s Third Theory of Comminution to calculate net power requirements when sizing ball mills*. Various correction factors may have to be applied.
The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material

See Page 1. • Based on Bond's Crushing Law, the power required to crush a certain material will change by % if the diameter of the product is made smaller by 50%. • In crushing a certain ore, the feed is such 80% is less than 50.8 mm in size and the product size is such that 80% is less than 6.35 mm.

size reduction circuits (Charles, 1957). However Bond’s Third Law can be reasonably applied to the range in which ball/rod mills operate in. In spite of the empirical basis of Bond’s theory, it is the most widely used method for the sizing of ball/rod mills and has become more likely a standard. The general form of Bond’s equation is as

Jan 01, 2016· A Bond ball mill work index is then performed on the mill product for the design of SAG-ball mill circuits. This is important because it was found that there was a 1–1.5 kWh/t higher ball mill work index if the –3.35 mm ball mill test feed size is obtained by SAG mill grinding compared with crushing.
1. BALL MILL AIM: To determine the energy required for crushing the given feed and thus obtain the work index for the same. Also determine the reduction ration and critical speed of the mill. THEORY: The ball mill is classified as an intermediate and fine grinder where the action of the grinding is based on impact and attrition.

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with
Ball mill is a metal cylinder which rotates about its horizontal axis. empirical laws have been proposed for calculation the energy requirements for crushing. The laws can be unified in a differential form as follows: n = 3/2, Bond’s Law: 4.
