The opencast coal mine has a top-down rock layer, gravel and cement, including Jurassic strata, middle sandstone, and fine sandstone and so on. The rock body owns the special features, for example slightly dense, hard, uniform structure. According to the role of the crushing condition, the different type’s rocks match the different reflection of crushing vibration. In a word, coal-bearing strata as homogeneous rock should be broken to a certain technology.
Most of the power plant require the final size of the coal which processed by surface coal mining plants to be less than 200mm.But the great majority small and medium sized opencast coal mine does not establish the crushing equipments. At the same time, the particle size of the coal product didn’t reach to the technical requirements, which directly impact on the economic benefits of the mine. To build a fixed crushing station, not only need a one-time investment, but increase cost of the second transport as well. It also affects the economic benefits of coal.
As the special nature of open-pit mining, coupled with technology is limited, surface coal mining has been restricted always. With the upgrading of mechanical equipment and technology, mining machine companies began to lucubrate on the open pit mining operation. To meet the market demand, Henan Hoxngxing Heavy Industry Company developed hydraulic drive wheeled vehicle chassis mobile crushing and screening equipment (mobile crusher is called for short). Henan Hoxngxing mobile crushing plant is widely used in road and bridge construction, urban construction, metallurgy, energy, and other departments of crushing, screening. It is especially suitable for surface coal mining areas, which including cone crusher series mobile crushing plant, jaw series mobile crusher, Impact series mobile crusher and screening series of mobile crushing station.
Henan Hoxngxing all type of mobile crushers are developed according to novel series design idea of stone crushing equipment, which expands the concept field of coarse crushing and fine crushing. Its design idea is based on the requirements of clients, which clears faults of the crushing place, surroundings and the complex basic configurations. This series mobile crusher really supply simpler, higher efficient lower cost machines for clients.
