Various Crushers Used to Process Coal
Coal crusher, also known as coal crushing plant, is the coal mining equipment designed for coal crushing process in energy industry. As the Mosh’s Hardness of coal is usually under 5, Hongxing Machinery design coal crusher, which is wit enough to process the raw materials with the hardness under 350Mpa, to handle all kinds of coal from hard coal, woody lignite coal to anthracite coal and petroleum coke.
Hongxing Machinery supplies a complete set of coal crushing plant together with other coal assistant equipments like coal feeder, coal screening plant and coal belt conveying equipment.
Coal crushing process is the important coal processing in coal energy industry. Hongxing Machinery offer the complete coal mining equipments in the coal crushing process. Coal crushing plant acts as the key crushing plant in this process.
Primary coal crusher works in the first stage of coal crushing process. Coal raw materials are firstly poured into vibrating feeder, which they will be fed into primary coal crusher continuously and evenly. Primary crusher is usually jaw crusher or impact crusher, producing lump coal cinder.
Secondary coal crusher crushes the lump coal cinder transported by coal conveyor. Secondary coal crusher usually includes hydraulic impact crusher, cone crusher and JC jaw crusher. It produces sand size coal particlc which can be used in pretreatment of coal directly.
Tertiary coal crusher resizes coal particlc into coal powder. Tertiary crusher is used in special occasions like the coal grinding mill has special requirements on the feeding size. Cone crusher can act as the tertiary coal crusher because of its fine final outlets.dryer machine:http://www.hx-crusher.com/dryer_machine.html

Hongxing Machinery is the leading coal crushing manufacturer in the world. Since Hongxing Machinery founded, we kept trying to develop new and better coal crusher for the coal industry. So now, Hongxing Machinery supply a Complete set of coal crushing plants.
Hongxing Machinery supply several types of coal crushers.
Mobile coal crusher is the coal crushing and screening plant which gathers coal feeding, crushing, screening and conveying in one unit. Hongxing Machinery have five series of mobile coal crushers: crawler tracked mobile crusher, mobile jaw crusher, mobile cone crusher, mobile impact crusher and multi-crushing mobile crusher.
Coal jaw crusher plays an important role in coal crushing plant. This coal crushing plant uses chewing force to process coal into the right size we need. Hongxing Machinery coal jaw crusher has two types: JC series European jaw crusher and PE series jaw crusher.
Coal hammer crusher works with hitting power and is widely used in coal processing. Single stage hammer crusher can crush the feeded materials of graininess1100mm into less than 20mm for one time. Coal hammer crusher is suitable for mid-hard and light erosive materials, whose pressure resistance strength is under 100Mpa and humidity lower than 15%.
Other coal crushers like coal cone crusher and coal impact crusher are also widely used in coal industry.
Coal processing goes as follow:
Coal is first crushed by coal crushers to a size of 20 to 25 mm and is then fed to coal bunkers. Coal feeders feed this crushed coal continuously to coal mill as per requirement. Coal gets ground by grinding elements in stages. Coal particles get re-circulated around four times before achieving required fineness.
