Why such a rock crusher crushing big capacity ?

All mechanical crushing with external force applied to the broken material rock crusher same is true , to overcome cohesion between material particles so that the material have broken . The cohesion of the material there are two: the role of the cohesive force between the crystal internal crystal dot ; another cohesion effect on the crystals and between the crystals , i.e. acts on the crystal interface . Two cohesion of the physical properties of the same , the difference is that the cohesion of different sizes , the former is many times larger than the latter .


Cohesion of size, depending on the nature and structure of the crystal itself block of material , also with dislocation and micro- cracks and other defects in the crystal structure . If you choose to the crystal material defects is broken, not only can save power and can guarantee the required size to reduce over crushed . Reached such a broken purpose called " selective crushing .


Selective fragmentation art method , the material should be crushed in the bulk grain layer to withstand the full range of extrusion , the initiator in the crystal or microcrystalline edge stress , material block should withstand the combined load , including shear , bending and torsion , the best of both tensile . If concrete crusher to withstand full range extrusion , the material in the crushing chamber ;Material block each other repeatedly shock or impact to the liner , the rapid transfer of the material block group ; control material layer density , make the material from the crushing chamber entrance to the exit , the crushing force is gradually increased . In addition, if the material layer using high frequency strong vibration effect, make the material blocks to each other to change direction the alternating shear and bending stresses , which can be generated in the feed block , this crushing method is called forced inner vibrating crusher .


The use of selective fragmentation method research , create a new process , made ??a variety of sizes crusher extremely high strength materials , can be broken without grain over crushed so as to achieve a work cycle , with a minimum the amount of force and energy consumption , high crushing ratio . The mechanical properties of the ore crushing effect on the material , crusher wear parts , strength and select crushing methods are important . The main consideration is the selection and design of the crusher .
