Most of the users of open pit mines are power plants, and the coal supply requirements for power plants are less than 200 mm.
Most small and medium-sized open-pit coal mines do not have Portable Crusher Plant. The particle size of coal does not meet the requirements, which directly affects the economic benefits of coal mines. The establishment of a fixed crushing station not only has a one-time investment, but also increases the secondary reversal link, which increases production costs. It also affects the economic benefits of coal mines. Open-pit coal mines have top-down rock layers, including cemented gravel layers and Jurassic strata, medium sand holes and fine sandstones. The rock mass is dense, hard, and uniform in structure. Moreover, under the condition of crushing, different types of rock and soil have different vibration responses to the fracture. Since the coal-bearing stratum is a homogeneous rock mass, the ability to accept the propagation of detonation waves is related to the nature of the rock mass. The harder the rock, the higher the density, and the greater the wave velocity, so the crushing technique of the *** method should be adopted.

Due to the special nature of open pit mining and limited technology, open pit coal mining has been restricted. With the improvement of mechanical equipment technology, Construction waste crusher are widely used in road and bridge construction, urban construction, metallurgy, energy, and other departments to break , screening and other operations, especially suitable for use in open pit mining.
It has low fuel consumption, low noise and reliable performance, providing a reliable, economical and environmentally friendly power source. The engine can be equipped with a military low-temperature preheating starter that allows the unit to be easily started in a low temperature environment of -25°C.
The operating system uses the imported servo pilot operating system, which is light and easy to control, and can achieve infinite walking speed. The successful development of this equipment has greatly accelerated the speed of open-pit mining and injected a new vitality into the mining industry.
