PEV Series Jaw Crusher
There are now two ranges of models in the PEV series range. The first is the well-known traditional jaw crusher range that is designed for stationary as well as mobile applications (PEV80, PEV100, PEV 3054, PEV110, PEV125, PEV140, PEV145, PEV160, PEV200).
Primary Crusher Optimisation for Improved Comminution …
The first step in the mining and processing of nearly any mineral ore is comminution. Since the oil embargo of 1979, the mining companies have been striving to reduce energy consumption and costs. The first serious step was the introduction of in-pit crushing in the early 1980s. With in-pit crushing accepted as a standard design mode, the energy saving emphasis turned to …
Selecting the right crusher for your operations
Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).

Size reduction control in cone crushers
Size reduction control of cone crushers has received fairly little attention over the past few decades. Consequently, the most common control objective is still to regulate the crusher load (crusher power or crusher main shaft piston pressure) or the closed side setting (the shortest distance between crushing liners), not the actual size reduction.
