Size Reduction and Energy Requirement - ScienceDirect

2016-1-1  So a measure of size or surface area before and after size reduction would indicate the extent of energy expended in the comminution process. Hence if E was the energy used for a desired size reduction, which resulted in a change in surface area S , it has been found that [13] , [14] , [15] , [16] , [17] : (3.1) d E = k [ S n d S ] where k is a constant and a function of the crushing strength of the rock.

Bond Work Index (Energy equation) - Grinding ...

2021-5-27  The Bond Work Index is a factor that measures the energy consumed in size reduction operation of the ore. The Bond's Work Index equation is: W=WI* (10/√P80 -10/√F80) where. W= the energy input (Work input) per ton, kwh/metric ton. WI= Work Index= specific energy per ton, kwh/metric ton (characterizes the ore)

Bond Work Index - an overview ScienceDirect Topics

As the closing size decreases, the ore must be ground finer, using more energy and producing a higher work index. Further simulations at even larger closing screen sizes show the BW i to increase. This dip in BW i with closing screen size has been observed experimentally, as shown in Figure 3.13 , with the minimum in BW i occurring at different closing screen sizes for different rock types [41,42] .

Crushing in Mineral Processing - 911 Metallurgist

2015-12-26  In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
