As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions.in addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.

gradations and capacities are most often based on a typical, well-graded choke feed to the crusher. choke feed is when the crusher cavity is kept full, without spilling out over the top of the crusher. minimal feed is when the crusher cavity is kept fairly low, just enough to ensure the crusher the article gives advice on crusher selection and application. some factors dictating selection include the desired product size, capacity, hard grove grindability index, percentage of rock to be freed and hardness of that rock. the hardness of coal probably has greatest impact on product fineness. typical dia Of coal crusher. typical curve of compressive strength versus diameter was drawn. proceedings of the world congress on engineering 2011 vol iii wce 2011, july 2011, london, u.k. shows that the crushing strength of coal is dependent on the diameter of agglomerates and the crushing strength is indirectly proportional to agglomerates diameter.
most secondary crushers are cone crushers and horizontal shaft impacts. for coal, many times, rotary breakers are used as primary crushers and ring granulators are used as secondary crushers. information on construction and working of various crushers is given in the following chapters.ring granulator type crushers are installed in many coal handling plants over framed type supporting structures either in steel or reinforced concrete. the causes of excessive vibrations commonly reported from these installations are discussed.5.1.1 crushers: In chp crusher work on principle of combination of impact and attrition crushing. In this type of crushing first coal is break due to impact and further scrub between two hard surfaces to get desired coal size. some crushers are work only on principle of impact crushing. generally these crushers are used before final crushers.
