·The grinding process in the jaw crusher was chosen as the process for the study those of the Bond comminution energy estimated from the Bond index There is considerable difference between
·Grinding and cutting reduce the size of solid materials by mechanical action dividing them into smaller particles Perhaps the most extensive application of grinding in the food industry is in the milling of grains to make flour but it is used in many other processes such as in the grinding of corn for manufacture of corn starch the grinding of sugar and the milling of
·A major use of the Bond s Work Index BWI model is to select the size of a grinding mill for a given duty A variety of correction factors CF have been developed to adapt the Bond formula to situations not included in the original calibration set and to account for relative efficiency differences in certain comminution equipment
The primary and secondary crushing operations were performed using a laboratory jaw crusher BB300 Mangan Retsch Retsch Allee Haan Germany and a roll crusher Sew Eurodrive GmbH & Co KG
·Jaw crusher movement is guided by pivoting one end of the swinging jaw and an eccentric motion located at the opposite end [4] The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws For instance a 22 x 30 jaw crusher has an opening of 22" by 30" a 46 x 46 jaw crusher has a opening of 46" square
·Bond work index Material Work index Bauxite Coal Dolomite Granite One approximate formula for jaw crusher capacity is given as Single toggle Blake type jaw crusher Source Courtesy of the Fuller Company a mixture of several materials However in spite of this the formula is workable
·With a lab scale jaw crusher as a test case an optimisation was made on how to operate it most energy efficiently by using an evolutionary algorithm numerical method For a selected optimised case an attempt was made to simulate the jaw crusher using a commercial software for discrete element modelling DEM after first simulating single
·distinguish crushing from grinding rather than mechanism of size reduction [4] There are primary and secondary crushers A primary crusher reduces large particles into smaller sizes for further crushing by the secondary crusher Examples of crushers include jaw crusher gyratory crusher and roll crusher
·The popular size reduction equipments for agricultural produce viz hammer mill ball mill burr mill jaw crusher gyratory crusher crushing roll cutter mill Reitz mill and colloid mills are explained using schematic diagrams Another empirical form of Bond s equation is written in terms of constant work index Assuming Bond
