Coal Mining Equipment
Mining equipment to concentrate coal is selected considering three aspects: properties of minerals in the deposit, type of separation process, and requirements of production. In order to do this will be necessary to consider the characteristics of the final product, economical aspects influenced by the coal content, size of the mill, and location. Shibang years of cases and experience to help you succeed!
Coal
Coal is a readily combustible black or brownish-black sedimentary rock normally occurring in rock strata in layers or veins called coal beds or coal seams .Coal is primarily used as a solid fuel to produce electricity and heat through combustion. people usually crush the larger coal block to small one by coal crushing plant, use coal mill or coal pulverizer to grind the coal.
The goal of coal mining is to remove coal from the ground. Coal is valued for its energy content, and since the 1880s is widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United States, United Kingdom, and South Africa, a coal mine and its structures are a "colliery".
Coal Mining Equipment
The Mohs hardness of coal is usually under 5, So can use jaw crusher, cone crusher, mobile crusher or hammer crusher etc. to handle it. After the coal has been crushed, we can use a vibrating screen to grade the coal by size and then transport the coal via belt conveyors. In this process, dewatering screen is an optional equipment to remove water from the product.
Shibang has 30 years manufacturing experience in coal mining equipment(coal crushing process, washing plant and belt conveyor). Shibang is a major coal crusher supplier for power plants and coke ovens, crushing limestone for blast furnaces, and crushing a wide range of raw and manufactured materials for industry.
As the largest exporter in the design and manufacture of coal crushers and spare parts, Shibang crushers are used in a wide variety of material reduction and processing applications in 100 countries around the world.
Coal milling process
A complete coal milling plant not only includes coal mill, but also other machines such as hammer crusher, hopper, deceleration machine, blower, dustpan elevator, electro-magnetic vibrating feeder, impulse dust cleaner, piping device, cyclone collector device, classifier, high-pressure moto and muffler.
Coal is grinded into powder in the coal mill, the fine particles will come into the cyclone collector with the airflow, and be discharged by the discharging value on the bottom of the collector. They are the final products. The airflow with little dust will be discharged through blower and muffler after being purified by the cyclone collector.
As professional coal mining equipment manufacturer and services provider, Shibang experts have researched several years about improving coal crushing efficiency and therefore reducing the waste substances and gas. For coal crush, Shibang jaw crusher has been widely applied for coal primary crushing. If needed secondary crush, there are Symons cone crushers, hydraulic cone crusher for your choice. Also, impact crusher is popular as tertiary crushing. After crushed by impact crusher, final products will be of cubic even shape.
