Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).

in the design of a grinding circuit. The Work Index is used when determining the size of the mill and grinding power required to produce the required ore throughput in a ball mill. 2. Procedure 2.1. Bond Ball Mill Grindability The sample was crushed to 100% passing 6 mesh (3.35mm), from this a 700 cc volume was measured and weighed to be used as feed for the Bond Mill. A feed particle size

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed
Selection and Design of Mill Liners. In Advances in Comminution, Ed. S.K. Kawatra After all, it is the interface between the mill and the grinding charge. Although work on the grinding action in mills was published 100 years ago (White 1905 and Davis 1919 High–low double wave ball mill liners These are a refinement of the wave

A) Total Apparent Volumetric Charge Filling including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume (inside liners). B) Overflow Discharge Mills operating at low ball fillings slurry may accumulate on top of the ball charge; causing, the Total Charge Filling Level to
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either
Mill diameter; Mineral density; Work Index. Bond estimated the amount of wear in terms of kilograms per kWh based on the abrasion index, A;, i.e., Wet Ball Mill = kg kWh = 0.16(A i-0.015) 0.33; Dry Ball Mill = kg / kWh = 0.023A i 0.5; Replacement Ball Size
determines the Bond Ball Mill Work Index used to determine net power requirements when sizing ball mills. The test is a closed-circuit, dry grindability test. It is run in a standard ball mill and can be performed at mesh sizes ranging from 48 mesh to 400 mesh. Bond Ball Mill Work Index (and modified Bond Work Index) data can be used in the CEET® grinding simulator. • The Bond Rod Mill
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
liners and lifters that are always fixed inside the shell of the mill. Liners and lifters have two main purposes: 1. Liners protect the outer shell of the mill from wear liners are renewable. 2. Lifters prevent slipping between the medium and slurry charge in the mill and the mill shell. Slippage will
The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material (feeders), and the system for discharging the output product. The size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 0.5 to 3.5. The
In order to analyze and reveal mathematical relations between the drop weight parameters and Bond work indexes, a data base on laboratory testing of various type ore grindability has been collected.
22-01-2021· The Bond work index was a significant evaluation criterion for ore grinding, which was proposed by American scientist F.C. Bond . The rationale of the Bond work index was the crack theory that the length of the new fracture produced by the ore grinding was proportional to the input energy .
