However, autogenous grinding is only one step in the total comminution process, which includes sizing, pumping, and often crushing. When evaluating a comminution circuit, energy consumption of all aspects of the system should be considered. The current comminution technology to reduce material to less than 52 microns is inefficient and limited.

consist of size reduction (or comminution) by crushing and grinding for the liberation of minerals, separation of mineral particles by va rious principles and a number of operations associated with them. However, most of the processes are basically physical (or mechanical), even if …
Both open and closed circuit crushing are employed. For close circuit the product is screened with a mesh size much less than the set. Fig. 6.4 is a typical set up where ore crushed in primary and secondary crushers are further reduced in size by a rough roll crusher in open circuit followed by finer size reduction in a closed circuit by roll ...
Crushing Equipment. The selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant (e.g. blasting pattern and mining method) and others which are downstream of the crushing plant (e.g. mill and grinding circuit selection).
The crushing and grinding process will produce a range of particles with varying degrees of liberation (Figure 2). Any particles that exceed a target size required for physical separation or chemical extraction are returned to the crushing or the grinding circuit. Figure 2.
DRA has been awarded the engineering and design of the Mt Keith Debottlenecking project by BHP Nickel West. The contract is for the provision of detailed engineering and design services to support the expansion of the crushing and grinding circuit at the Mt Keith Operation, including new stockpile feed conveyors, coarse ore stockpile, reclaim conveyor, 16 MW SAG Mill grinding circuit and an ...
