Bond Mill Power Equation

The wood chips were successively ground in a hammer mill using screen sies of 25.4 10 6.4 and 3.2 mm. The input power and the flow of material into the hammer mill were recorded continuously. The recorded power input vs. mean particle sie showed that the Rittinger equation had the best fit to the experimental data.

The optimal ball diameter in a mill. of the equation for determining the optimal ball diameter depending on the The ball sie in a mill has a significant influence on the mill throughput power. Chat Now

2018220power according to the Bond Third Theory method. Rod mill and AGSAG mill products are similar and tend to be not as steep as a 0.5 slope when plotted on loglog paper. This is because the particle sie distribution PSD these mills produce have a coarse fraction but also a ne fraction which is

Canada ABSTRACT This work presents a public database of over 800 grindability measurements and a set of equations for converting between different grindability tests based on this database. Several laboratory

Bond Rod Mill Grindability Test. The test determines the Bond Rod Mill Work Index which is used with Bonds Third Theory of Comminution to calculate net power requirements when siing ball mills. Various correction factors may have to be applied. The test is a closedcircuit dry grindability test performed in a standard rod mill.

2019127tion related to the operation of the circuit F80 P80 power and mill feed rate. 7.DETERMINING THE BOND EFFICIENCY OF A GRINDING CIRCUIT 7.1Method In the plant 1. Define the circuit for which the Bond Efficiency is to be determined. 2. Procure samples of the circuit feed and product. 3. Obtain the power draw of the sie reduction equipment

The Rowland and Kjos equation indicates that power draw is a function of the fraction of the critical speed for the mill. Bond quantified the rod mill power draw as a function of the Work Index capacity and a series of correction factors AMIT 135 Lesson 8 Rod Mills

Development of an equation for tumbling charge and balls plus comparison to plant data suggests that the net mill power for cylindrical semiautogenous mills can be calculated from mp
