There are many kinds of rocks, such as limestone, limestone, granite, basalt, river pebbles, pebbles, etc. These rocks can be used as construction materials after being crushed, and are widely used in railways, highways, hydropower, bridges and other engineering projects. Different crusher equipment is required for different rocks.
1. Limestone
Limestone, also called limestone or bluestone, is the most crushed material in the mining equipment industry, and its main component is calcite. Limestone crushing is mostly used in the production of cement. After mining, the particle size is larger and the hardness is higher. The impact crusher mainly relies on impact energy to complete the material crushing operation. When working, the motor drives the rotor to rotate at high speed in the crushing chamber. The material is fed into the machine from the upper feeding port and is crushed by the blow, impact, shearing and grinding action of the high-speed hammer, which can achieve the ideal strength of raw materials for cement production.

2. Granite
Granite is an igneous rock formed by the condensation of magma below the earth’s surface. Its main components are feldspar and quartz. Due to its high hardness and wear resistance, in addition to being used in high-end architectural decoration projects and hall floors, it is also the first choice material for open-air sculptures. It can be broken by jaw crusher for primary crushing and cone crusher for secondary crushing. According to requirements, counterattack breaking or fine jaw breaking can also be added as the third breaking.
3. Pebble crushing equipment
Pebbles are a by-product of mining yellow sand, so they are named because they resemble pebbles. Pebbles have high hardness, among which the silicon content is the highest. Pebbles are relatively rich in resources and low in cost. Today, when natural sand is increasingly in short supply, artificial sand making from pebbles has become a new trend. In view of the characteristics of cobblestones, after considering the investment cost and production cost of the crushing project, a reasonable crushing process was developed, including jaw crusher + cone crusher + sand making machine to produce artificial sand.
