Coal crusher or crushing machine application in coal processing

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).

Coal crushing plant working process

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.
