Choose the crusher according to the type of rock

When crushing rocks, selecting the appropriate stone crusher requires analyzing the rock's composition. Different types of rocks with varying water content necessitate different crusher types. Below are some different types of rocks:

1. Granite.

Granite's main mineral components are quartz and feldspar, along with smaller amounts of other minerals such as mica and amphibole. These silicate minerals are typically distributed in an arbitrary orientation. Granite comes in a variety of colors, from green to gray and from pink to red, making it suitable as a decorative building material for countertops, building facades, and floor slabs. Granite possesses high strength, high hardness, and roughness, but it also has internal weak points, allowing for easy extraction of rectangular blocks from the parent rock for transportation during open-pit mining.

2. Calcite: The most important carbonate mineral, with perfect rhombohedral cleavage, vitreous luster, transparent to translucent, usually white or colorless, but other colors are also common. It has a white streak, a hardness of 3.0, and a specific gravity of 2.71. It is soluble in dilute hydrochloric acid, producing effervescence. Pure, transparent calcite is called Iceland spar.

It exhibits strong birefringence and perfect cleavage.

3. Limestone: Limestone has many uses, such as as a raw material for iron smelting, cement and quicklime production, as an aggregate filler in Portland cement concrete and asphalt concrete, and in load-bearing masonry structures.

4. Sandstone: Also known as sandstone, it is a sedimentary rock, mainly composed of cemented sand grains, with a sand content greater than 50%. Most sandstone is composed of quartz or feldspar, the most common components of the Earth's crust. It has a sand content greater than 50%, a stable structure, and is usually light brown or reddish, mainly containing silicon, calcium, clay, and iron oxide.

When crushing rocks with a high Mohs hardness, such as granite, primary jaw crushers or cone crushers are suitable. For crushing rocks with a lower Mohs hardness, such as calcite, hammer crushers are more appropriate.
