2018626The Bond rod mill work index is not as common as the Bond ball mill work index and there are two different variations on the mill apparatus.The SAGMILLING.COM models expect a mill with a wave liner and is not compatible with mills using smooth liners.
This 12 x 12 ball mill is universally used for grindability testing and determination of the Bond Work Index. Mill comes complete with ball charge and control panel with automatic revolution counter.
Bond Ball Mill Index Test JKTech. A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mills and the associated grinding circuits. Sample Requirements A minimum of 10 kg of material crushed to nominally minus 10 mm is preferred. JKTech would stage crush the sample to minus 3.35 mm as required for the

2010421determination of the work index for ball and rod mills in 1952 and modified it in 1961. The standard Bond ball mill grindability test is a closed circuit dry grinding test with a 250 circulating load. The standard procedural outline of the test is stated in Bond 1961. The work index for a ball mill Wi is then calculated from the following

Numerically the work index is the energy required in kwht to reduce a given material from theoretically infinite feed sie to 80 passing 100 microns. The work index of a particular material is determined in the laboratory by conducting the standard Bond grindability test. Bond developed separate tests for the rod mill and the ball mill. The

Rittingers Kicks and Bonds laws express work input as work index W i times a particle sie function. It is proposed that these laws are only particular cases of more general expressions having the particle sie function raised to an exponent i.e. the work exponent W e.
Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 106 microns. The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 250 microns. The CenterPeriphery Discharge mill has feed reporting from both ends and the product discharges
The Bond Ball Work Index Test determines the resistance of ore to grinding in a ball mill expressed as a work index kilo Watt hour per ton kWht. The work index is then used to calculate the specific energy requirements for siing ball mills or determining their throughput for a
