This characteristic of ball media wear rate vs the bond index was investigate at part of the AMIRA P9L project . It was found the systems dominated by corrosive wear mechanisms (ie: mild steel media) had wear rate in the 100159g/kwh range and the systems that did not have corrosive wear mechanisms (Cr media or noncorrosive ores) and were dominated by abrasive and impact wear ...

The Hardinge Mill is adapted to the complete finishing of limestone mixtures, coal and cement clinker, in one operation. To accomplish this with a good output, it is advisable to crush the feed to 3/4″, or preferably 1/2″ in size. This will allow the use of balls ranging from about 1 1/2″ in diameter to 3/4″, and will give a large ...

cost study, and the required accuracy of the estimate. Depending on these three factors, cost estimation should always be within a given accuracy for a given type of study. Problems arise when those using the cost estimates and those making the cost estimation are not in complete understanding of the accuracy of the estimates.

This paper compares two deconvolution methodologies used to estimate residence time distributions (RTD) in industrial closedcircuit ball mills. Parametric and nonparametric deconvolution techniques were evaluated. Both techniques allowed for direct RTD estimates from inlet and outlet tracer measurements in the mills, with no need for mass balances nor assumptions to correct the effect of the ...

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

The calculation formula for the mill filling degree is as follows: Mill Filling Degree = (Volume of the mill charge / Internal volume of the mill) x . For example, if the internal volume of the mill is 100 cubic meters and the volume of the charge is 35 cubic meters, then the mill filling degree would be: Mill Filling Degree = (35 / 100) x ...
