Get QuoteThe Work Index Ball Mill is used to find Grinding work index, referring to the grindability index of Ores, it indicate the grinding difficulty of the material. It is measured according to the principle that to calculate the grinding work index based on output of each revolution of the mill after the material is ground to a balanced state by the specified mill.

Get QuoteAt least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill. The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas Ball Mill Work Index (BWI) is used for the range from 2.1 mm down to 100 m. Adjustment of grinding parameters.
Get QuoteThis ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types grid type ball mill and overflow type ball mill.

Get QuoteNov 01, 2002 Equations for power draft, capacity and work input for predicting the performance of industrial grinding mills are derived based on torque measurements using a laboratory instrumented mill. These derivations are based on mechanical principles and on the first-order kinetics of the grinding process. Rittinger’s, Kick’s and Bond’s laws express work input as work index (Wi) times a particle.
Get QuoteJun 19, 2015 A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80 passing inch (6350 microns). The required product size distribution is to be 80 passing 100 mesh (149 microns). In order to determine the power requirement, the steps are as follows.
Get QuoteMixer Mills grind and homogenize small sample volumes quickly and efficiently by impact and friction. These ball mills are suitable for dry, wet and cryogenic grinding as well as for cell disruption for DNA RNA recovery. Planetary Ball Mills meet and exceed all requirements for fast and reproducible grinding to analytical fineness. They are used for the most demanding tasks in the laboratory, from.
