In numerical terms, the working index measured in kW so, this indicator shows the energy amount needs to be spent on grinding the one short ton of material. depending on the method of crushinggrinding, the the bond index conforming rod charge consists of: rods of 1.25 diameter and length. rods of 1.75 diameter and length. the grinding jar for the bond index rod mill is in size and has a wave-shaped design. At least to kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.

grinding circuit efficiency. bond work index efficiency has been widely used by industry, but until now without concise standard methods, or a formal guideline, for doing so. the bond efficiency subcommittee of the industrial comminution efficiency work group of gmsg hasjan 01, 1989 the bond work index, as an indicator of the grindability of raw materials is not a material constant but rather it changes with change of size of the grinding product.therefore, in practice we can expect some difficulties and errors when the energy consumption is determined according to this formula in the case when, for a given size of grinding product, the value of the work index bond ball mill industar. bond ball mill the fcbondwork index testball millwas designed by cbondfor use in determining thebondindex, a measure of grindability and power required for grinding applications the fcbond millsare used in laboratories throughout the world a copy of fred cbonds method of crushing and grinding for determination of thebondindex isetermining the bond efficiency OF industrial grinding circuits calculations: calculate the actual operating bond work index of the grinding circuit. estimate the and calculate the work or specific energy input from the size reduction equipment power and circuit tonnage auxiliary equipment power is excluded.
