Jaw crusher has the features of simple structure, low running cost , large angle, uniform output particle size, long service life and easy maintenance. Nowadays, it is widely used in metallurgy, building materials, mining and chemical industry. In mining machinery industry, jaw crusher is mostly used in coarse and secondary crushing. For ores with high or special hardness, it can achieve great crushing effect.
The work principle of jaw crusher: motor drive belt and pulley make moving jaw move up and down through the eccentric shaft; When the dynamic jaw rise, the angle between the bracket and the dynamic jaw largen, so as to promote dynamic jaw plate close to static jaw plate, at the same time the material being crushed or broken to achieve the purpose of crushing materials; When the dynamic jaw moving downward, the angle between the bracket and dynamic jaw diminish, the dynamic jaw plate get away from the static jaw plate by the function of the pull rod and sping, at which time the broken materials are discharged from the down mouth of the crushing cavity. The machine periodically crush and discharge materials with the motor turns continuously to realize batch production.
The detailed performance advantages of jaw crusher are listed as follows:
1.Energy saving; Discharging mouth has a big adjustable range, which can fulfill the needs of different customers.
2. Low noise, little dust; when the machine is working, there's no need for people to concern about the pollution issue.
3. Crushing cavity is deep and without dead zones, which improves the production capacity and yield.
4. Jaw crusher has a big crushing ratio and the particle size of the product is uniform5. The lubrication system of jaw crusher is safe, reliable and convenient to replace the parts.
