Jaw crushers are designed for primary crushing of hard rocks without rubbing and with minimum dust. Jaw crushers may be utilized for materials such as coal, granite, basalt, river gravel, bauxite, marble ...
The crushing process is performed in two large stages, which require speciﬁc equipment to achieve proper granulometry. First there is a primary crushing or coarse crushing to crush big rocks. Second, there is a secundary grinding stage to achieve the right size.
Crushing and Grinding Wet Sticky Ore. In the handling of wet sticky ores such as encountered in tropical areas having distinct dry and rainy seasons the crushing plant is a section of the mill which must be planned very carefully Unless this is done crushing becomes a constant source of trouble resulting in lost production and high milling cost

to the SAG mill. In other words, crushing plants, from primary to quaternary circuits, are here to stay. There are three main steps in designing a good crushing plant: process design, equipment selection, and layout. The first two are dictated by production requirements and design parameters, but the
Primary crushing generally reduces material up to 0.3 meter (m) (1 foot [ft]) in diameter down to 1 centimeter (cm) (0.40 inch [in.]) in diameter. Secondary crushing reduces particle size down to approximately 1 millimeter (mm) (0.04 in.) in diameter. Fine grinding or milling reduces the particle size down to as low as 1.0

Primary Crushing. From the standpoint of the process flowsheet, instrumentation in the primary crushing facility is a logical starting point. While there have been some notable successes in primary crushing plants employing no local operators, most primary facilities, large and small, continue to employ a local operator for a variety of reasons.
In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

use of HPGR for hard rock multi-stage crushing and ball mill circuits at high tonnage rates (Parker et al, 2001). Table 2 provides a simple comparison of the various comminution circuits. The primary mill may be operated in open circuit or closed by a classifier, such as a screen or a hydrocyclone.
Crushing is typically a dry operation that is performed in two- or three-stages (i.e., primary, secondary, tertiary crushing). Lumps of run-of-mine ore as large as 1.5 m across are reduced in the primary crushing stage to 10–20 cm in heavy-duty machines. In most operations, the primary crushing schedule is the same as the mining schedule.
