THE EFFICIENCY OF BLASTING VERSES CRUSHING AND

2013-4-21  Crushing is done in three stages, reducing to 80% passing 2 cm (3/4 inch). Rod and ball mills take the ore down to an 80% passing size of 60 microns (270 mesh). METHODOLOGY The Bond equation is a useful tool to compare predicted and actual values of energy requirements for each step in taconite comminution. Crushing and grinding energy are measured

Difference between Crushing and Grinding

2017-2-17  According to this, if we now further crush down to diameter z the additional work done is Q (1/z 1/y), and the total work done in crushing from diameter x to diameter z = Q (1/y 1/x) + Q (1/z 1/y), which = Q (1/z 1/x), the same as if the crushing were all done in one operation. To make the computation, then, it is necessary to determine the

CRUSHING AND GRINDING EQUIPMENT Latest

2015-7-1  This kind of grinding occurs when a layer of material is pinched between the two crushing liners so that the biggest particle size remains significantly smaller than the gap between the crushing parts. The grinding force cannot go through a single grain (mo-no-granular comminution) but diffused in a collection of grains

Crushing Vs Grinding Minerallurgy

In crushing, particles are reduced in size to such a level that grinding can be conducted, while grinding allows to achieve the desired liberation size. Besides, the process of comminution can be simple or complicated depending on the nature of the ore and the suitable degree of liberation.
