What is the Bond Work Index Formula-Equation?In case you had forgotten crushing and abrasion. The calculations and experimental studies indicate that no more than 5% of the supplied energy is used directly for crushing (the decrease of material particle size) and the rest of the energy is converted into heat and sound one and,

or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Contact Now. Contact SupplierBond f c 1961 crushing and grinding calculations mill Ab based on the average performance of the plant circuits that Bond correlated with his laboratory testing. This circuit is consuming 89% of the Bond specified (design) circuit energy. 7.2.2 Common Plant Grinding Circuit Calculations 1. …A Bond rod mill work index test (BRMWI) is a standard test for determining the rod mill work index of an ore sample [21]. The BRMWI is a measure of the resistance of the material to crushing and grinding in a rod mill and is used to calculate the grinding power needed for a given material parcel regarding rod mill grinding conditions.Example calculation of test mill grinding rates Whether from a plant survey or torque-mill test,

respectively. Bond developed a standard laboratory test for the determination of the work index for ball and rod mills in 1952 and modified it in 1961.

but it is generally accepted that of all the energy used in the World something like between 1 and 10% is in comminution rod milling and ball milling where different work index values are applied to each range to arrive at the Bond SE value. After applying the AG/SAG factor to the Bond SE value corrections are made for the SG,

is accomplished by reducing the size of run-of-mine ore down to 25 mm (1 in) using equipment that compress the ore against rigid surfaces. The equipment can also reduce the size of the ore by impacting it against surfaces in a constrained path.Example calculation of test mill grinding rates Whether from a plant survey or torque-mill test,
