of crystalline silica in the earth’s crust and the wide uses of the materials in which it is a constit - uent, workers may be exposed to crystalline silica in a large variety of industries and occupations (IARC, 1997). Table 1.2 lists the main industries and activities in which workers could be exposed to crystalline silica.
Silica content is generally lower in natural stone products. Calcium-based stones, including limestone and certain varieties of marble (e.g., calcite, dolomite, and onyx), contain little or no silica. In contrast, granite can contain up to 45-50% silica. The table below describes typical silica/ quartz content of common natural and engineered ...

1. Single or Double shaft type impact hammer crushers: Impact hammer crushers are used when generally compressive strength of limestone is <150 MPa, Moh’s hardness value is < 4 and max. Silica content is approximately 8 per cent. These crushers can take up to 10 per cent moisture for single shaft and maximum 20 per cent moisture for double shaft.

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.
LIMESTONE (1 - 5% Silica) 11 TOXICOLOGICAL INFORMATION In October 1996, an IARC working group reassessing crystalline silica, a component of this product, designated crystalline silica as a carcinogen.

Quartz (silica) is the mineral form of silicon dioxide (SiO 2). Chert is often of biological origin (organic) but may also occur inorganically as a chemical precipitate or a diagenetic replacement (e.g., petrified wood). Geologists use chert as a generic name for any type of microcrystalline or cryptocrystalline quartz.
