As everyone knows the jaw crusher equipment is the most widely used mining machinery equipment, one of the most common crusher equipment, because it has the advantages of simple structure, reliable work, easy manufacture, convenient repair, good adaptability, so basically is used in primary crusher.The jaw crusher type large machinery and equipment, so inevitably some mechanical failure or problem what, then we will find out the cause of the problem, modify. The tooth plate (dental plate) is an important component of jaw crusher machine, tooth plate life almost decided to jaw crusher crusher life, today Zhejiang's largest manufacturers - black and white machine, would like to tell you how to extend the jaw crusher toothed plate service life.If you want to extend the jaw crusher toothed plate service life design, material, we can crusher teeth plate from the jaw assembly, the use of the process improvement and other aspects, this can be very good to strengthen the jaw crusher toothed plate service life, but also can improve the jaw crusher production efficiency, to reduce production cost.In the design, the broken plate of jaw crusher jaw and the fixed jaw tooth to tooth should peak valley. So, the
jaw crusher of material in addition to extrusion effect, and bending, the material more easily broken. In order to enhance the service life of the broken plate, upper and lower symmetry breaking plate is designed into the shape of small and medium crushing machine, when the lower wear adjustable head; large jaw crusher teeth plate design into several pieces symmetrical with each other, so that the wear can be exchanged to use tooth plate. Jaw crusher plate material crusher can choose the service life is long, the cost low manganese steel (ZGMn13). Manganese steel toughness is good, has the characteristics of cold hardening, under the pressure function will continue to be strengthened, so continue to work wear and strengthens unceasingly, until wear to cannot be used until retirement.When assembling, jaw crusher teeth plate must be firmly affixed to the jaw plate, between the two should level up, between the tooth plate and a jaw with a soft metal gasket and bolt fastening. Jaw crusher teeth plate work, should not have loose phenomenon, otherwise easy to break or wear tooth plate, reduce the service life of the tooth plate. So, the jaw crusher machine assembly must be installed tooth plate, thereby prolonging the service life of the tooth plate.Finally, in the jaw crusher machine in the use process, if the bolt vibration, meet the jaw type crusher toothed plate and the toothed plate nut loose, more serious loss, or directly make tooth plate broken in jaw crusher equipment downtime, affect the normal production, don't panic, jaw crusher using the process can be according to the specific circumstances to think of a way to solve the specific problems, to prevent tooth plate loosening, increased wear, broken, thereby prolonging the service life of the tooth plate, reduce cost, improve work efficiency.
