Ball mills tumble iron or steel balls with the ore. The balls are initially 510 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.
Oct 22, 2020 Ball mill is an energy-intensive device for grinding and breaking iron ore particles, which is extensively used in mineral, cement, chemical, and other industries.14 In the field of mineral processing, a portion of the energy is converted into heat that will raise the milling tem-perature and breakage characteristics of iron ore will
First, a Jar Mill Grindability Test requires a 5 lb. 2 kg sample and produces a direct measured specific energy net Hp-hrt to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy value net Hp-hrt from an empirical formula.

Ball mill introduction. The ball mill is a key equipment for grinding materials, widely used in powder-making production line such as cement, silicate sand, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. Ball mill can grind various ores and materials with dry type or wet type.
Mar 08, 2021 Ball mill and rod mill are suitable for different materials 1. Selection by materials hardness Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals. 2. Selection by required particle size
75 100 mm diameters. Ball mill balls experience a greater number of impacts, but at lower magnitude than SAG mill balls, due to the smaller ball size, and smaller mill diameter. Feeds are typically highly abrasive, contributing 10 15 mhr wear for softer ores and 20 mhr for abrasive gold, copper
Inside the ball mill, the crushed iron ore will grind the ore to about 0.2 mm with 3-inch steel balls. 3.This iron ore slurry is pumped to the agitation tank. This iron ore slurry is finally pumped to the flotation machine with the fine sulfide ore -0.074 mm going to froth flotation cells for recovery of iron.
The liner sample is made of Mn16 steel, the ball had a diameter of 25 mm and was made of GCr15 steel, and the iron ore powder was screened from the magnetite particles with mesh number of 20.
The ball mill abrasion test BMAT promises to offer accurate prediction of relative service lives of wear-resistant alloys for liners and grinding media in mineral grinding environments.
