resistance of the rock to crushing and grinding and numerically is the kilowatt-hours per short ton required to reduce the rock from infinite feed size to 80% passing 100 mm. The work index varies for different rock types. SAFETY AND HEALTH The structural geology of the rock plays an important role in rock stability and safety in quarries.

These sedimentary rocks are also very extensively used as building stones at places of their occurrence but all varieties are not suitable for this purpose. Limestones show great variation in their properties and appearance. Thus in crushing strength, they may be softer than a good brick (less than 200 kg/cm 2) or may be as strong as 1000-1500

In the granite crushing production lines, we can choose the right granite crushing machine according to the capacity. The granite stone crushing plant could be placed in concrete building or shed or open space. The usual crushing plants are as follows: 30-50tph, 50-80tph, 80-120tph, 120-200tph, 200-300tph, 300-400tph, 400-500tph.

Many types of crushed stone: Crushed stone is not a "standardized commodity." It is made by mining one of several types of rock such as limestone, granite, trap rock, scoria, basalt, dolomite, or sandstone; crushing the rock; and then screening the crushed rock to sizes that are suitable for the intended end use.

In general, compared to intact rock, a rock mass has reduced tensile strength (almost zero), and reduced shear strength especi ally along discontinuity planes. Furthermore, if a rock mass is cut by directional joint sets , the rock mass strength is anisotropic. Rock mass strength is scale dependent and varies with the volume of rock under

Rock is one of the geomaterial used in construction in form of concrete, aggregate, building stone, and armourstone [1-4]. The suitability of rock for any civil engineering construction work depends on its physical property [5] and this is one of the basic goals of rock mechanics: to provide useful information and methods for

Usually hard-rock gold is microscopic and is impossible to collect without advanced milling processes. For example, this piece of milky quartz looks like a plain white rock, but when assayed it ran 14 grams of gold per ton. So in theory, one ton of that rock when milled and processed would yield about one half ounce of gold (assuming 100%

Rocks can be crushed and graded to make aggregate which can be added to a bonding material like cement to form concrete, or bitumen to serve as a road stone. Various civil engineering works need different grades of aggregate. The particle size distribution within an aggregate is specified for any particular situation.
