Both of the old theories have been remarkably barren of practical results when applied to actual crushing and grinding installations. The need for a new satisfactory theory is more acute than those not directly concerned, with crushing and grinding calculations can realize.

BondFC1961CrushingandGrindingCalculations Anyone wondering how Bond ball mill work index compares versus SPI or JK A*b? Well, M. Doll says, several comparisons have been published, such as at CMP 2011 and Procemin 2009 and in general, the Wi_BM is not compatible with the other two because they measure different size classes.

Abstract: The Bond work index is a measure of ore resistance to crushing and grinding and is determined using the Bond grindability test. Its value constitutes ore characteristic and is used for industrial comminution plants designing. Determining the Bond work index value is quite complicated, time

The test results confirmed the beneficial effect of circulating load, and also that the throughput benefits of higher circulating load are limited due to classification efficiency. The effect of classification efficiency and circulating load was also investigated by Morrell (2008) who used Bond ball mill tests as the base line (Bond, 1962).
Jan 31, 2012· How to calculate the Yield to Maturity (YTM) of a bond. The equation below gives the value of a bond at time 0. The cash flows of the bond, coupon payments (CP) and Maturity Value (MV = Principal Amount + Coupon payment) have been discounted at the yieldtomaturity (YTM) rate, r, in order to determine the present value of cash flows or alternatively the price or value of the bond (V Bond).
