The cone crusher is a modified gyratory crusher, and accordingly many of the same terms including gape, set, and throw, apply. The essential difference is that the shorter spindle of the cone crusher is not suspended, as in the gyratory, but is supported in a curved, universal bearing below the gyratory head or cone (Figure 6.8).Major suppliers of cone …

Mineral Sizers are used to process high volumes of hard rock minerals such as iron ore, copper, gold and nickel in primary crushing applications, as well as soft, non-coal minerals, lower capacity battery minerals and rare earth minerals such as spodumene, antimony and cobalt in secondary crushing…
The process of reducing mined ore for processing is known as 'comminution', which is defined as 'the action of reducing a material, especially a mineral ore, to minute particles or fragments'; this is normally achieved at mining operations through one or more stages of crushing and milling.. Early mining activities were labour intensive. Ore breakdown …

A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it ...
The extent to which fine crushing can be carried out will vary and depends on the ore characteristics, plant and crusher design. Unfortunately, the ore characteristics are generally beyond our control, so the concentration of effort lies primarily on the plant arrangement, equipment design and operation.
