Industrial minerals and rocks are a group of naturally occurring, mostly non-metallic minerals and rocks, including materials such as sand and gravel, stone (e.g., limestone, dolomite, granite, serpentinite and quartzite), glass sands, feldspar, phosphate, sulfur and potash (NTIS, 2000). At an appropriate opportunity cost these materials are of great economic value as main raw materials for

In mineral processing, the reduction of minerals by crushing and grinding may be regarded as having one or other of two main objectives: the attainment of a size appropriate for the direct industrial application of the mineral, e.g. barytes, sand, aggregate; or the release of metallic or ore inclusions from an unwanted matrix with a view to maximum separation.

Our Large Industrial Rock Crushers employ two planer-crushing surfaces set at a small angle to each other and convergent downward. One plane is fixed and the other is pivoted either top or bottom allowing a reciprocating motion when pushed by a pitman-toggle arrangement activated by an eccentric drive.

In order to separate the minerals from gangue (the waste minerals), it is necessary to crush and grind the rock to unlock, or liberate, valuable minerals so that they are partially or fully exposed. This process of size reduction is called comminution. The crushing and grinding process will produce a range of particles with varying degrees of liberation (Figure 2). Any particles that exceed a

Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing, to liberate and concentrate those valuable minerals.
