Application of mobile crushing station in open pit mining industry

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.

Artificial aggregate production process and advantages and disadvantages

Wool sand making machine by crushing, screening, grinding, washing the resulting sand and gravel. In the absence of natural sand areas, often using artificial aggregate pouring concrete. Artificial aggregate production process are: wool mining, processing coarse aggregate, fine aggregate processing, screening, after washing reserves and transportation. Advantages of artificial aggregate are: ① wool stope nearest arrangements, reduce storage, loading and transport links, saving investment; ② to adjust production mix than the aggregate of all levels make full use of wool, save mining cost; ③ artificial aggregate particle size distribution is good, save cement, fresh surface roughness to increase bond strength, good mechanical properties. The disadvantage is the need to increase drilling blasting, crushing, sieving, washing, sand and other processes, the process is cumbersome, install more equipment and a greater direct costs of the system. Wool sand by crushing, screening, grinding, wa...

Raymond Mill grinding system new advantages

Raymond Mill is a kind of grinding equipment that we commonly use in industrial ultrafine mill . It is suitable for limestone, calcite, marble, talc, gypsum, barite, fluorite, zeolite, manganese ore, ilmenite, phosphorus Minerals, bentonite, starch, kaolin and other stones with a hardness of less than Mohs 7 are ground and used in a wide range of applications, all of which are inextricably linked to its new grinding system. So what technology is applied to the grinding system used by Raymond Mill? 1. The new technology adopts a new vertical roll device. The grinding roller and the grinding ring are always in balance during the grinding process to form a uniform line contact grinding zone. The height of the grinding roller and grinding ring is increased from the original 160 mm to 200 mm, which increases the grinding contact area to a greater extent. 2. The classifier adopts a forced turbine classifier to extend the granularity of the finished product from the original 80-325 mesh range...

New sand maker consolidates infrastructure construction

Since the 18th National Party Congress, our country has been inclined tocontinue to invest heavily in infrastructure to promote economicbooming, which will further expand the market demand for vsi sand making machine and gravelaggregate. In the face of the huge gravel aggregate demand, it isnecessary for gravel equipment R D manufacturer to activelyprepare for high-tech sand making machine to help the rapid development of economy. Sand making equipment is the key to the production of high-quality sandand gravel aggregate, the quality of sand and gravel aggregates directlyaffects the quality of infrastructure works. For a long time, theoverall technical level of sand making is low; facing increasinglystringent technical and quality requirements in the market, China sandmaking machine manufactures require to take active innovation, furtherincrease R D investment on technological application to meet thehigh standards and high demand of the market. Hongxing machine deeply understands...
