- Coal crushing plant outline
Coal crushing can be divided into two categories according to their position in the production system such as crushing preparations and finally crushing. Crushing preparations work for the next operational requirements of the particle size for crushing operations; finally broken coal is broken to the required size of the operation of commercial coal. Coal crushing commonly used mechanical method. In a variety of crushing machines of coal, we often dominated by a kind of broken way, accompanied by other fragmentation methods.
Which coal crusher are used in the coal crushing plant depending on the physical and mechanical properties of materials, particle size and the requirements of broken than to decide.
There are two coal crushing operation systems: open systems and closed-circuit crushing system. Open crushing system is used on the product's size is not strictly required, or crushed when the situation does not produce too large, while closed-circuit crushing system called loop crushed system, broken product for less than the specified size must be strictly guaranteed, while the crusher machine itself cannot meet this requirement of the situation. Crushed in the closed-loop system, the crushed product to check through the screen, screen then return to the coal crusher, until through the screen so far.- Coal crushing plant components: coal crusher
Coal crushing plant mainly includes many coal equipments. From SBM you can get coal crusher and coal mill.
Jaw crusher is the most commonly used coal crusher machine in coal handling process. According to our experience, we know that jaw crusher is applied for the content of large waste rock hard or brown coal of the broken iron. As a primary crusher of coal crushing plant, SBM jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. It’s widely applied to crush high hardness, mid hardness and soft rocks and ores such as slag, construction materials, and coal ore and so on. According to its features and working principle, choosing SBM jaw crusher for coal crushing plant is the right choice.
Depending on the characteristics of coal, many stone crushers can be used in coal crushing plant. JC series jaw crusher is an upgrade of jaw crusher; impact crusher crushes materials with impact force. And other crushers are crushed for coal such as spring cone crusher, CS Cone Crusher, hydraulic cone crusher, vertical shaft impact crusher and so on. Also, some of our new type mobile crusher station can be used for coal crushing process. Large coal enterprises attach much importance to crushers’ capacity, quality, maintenance and the cost-effectiveness in the long term. SBM crawler type mobile crusher minimizes the equipment downtime and integrates the coal conveying and crushing, thus greatly reduces the use cost. It is favored by large coal enterprises, especially coal mine, as it meets their requirements for high capacity and efficiency processing of the coal.- Coal crusher or crushing machine application in coal processing company
- 1. Meet the requirements of coal particle size selected. Featured the coal machine can handle a certain size range, over the range of large to go through a break before washing.
2. Some coal is a mixture of coal and waste rock symbiotic parting of coal, in order to choose the coal that needs to be broken into smaller particle size, separation of coal and waste rock. The most common case is to be elected in the primary election machine coal crushed to 13mm or 6mm following, and then sent to re-elect re-election machine.
3. Size to meet user requirements, the products or coal broken after the election to a certain size. According to the product size broken, broken job can be divided into coarse pieces (the crushing to 50mm and above), in pieces (broken into 25-6mm), small and fragmented (broken into 6-1mm), crushed (1mm or less).
