Tooth Form of Jaw Plate Has Impact on Efficiency

The compound pendulum jaw crusher is one of the most important product in the crushing industry. It has the advantages of simple structure, easy maintenance, high reliability, and large crushing ratio. The speed of development of the jaw crusher is quick. There are products coming out every 5 ~ l0 years, including the improvements from the rack to the jaw plate and various of parts.
The movable jaw plate and the fixed jaw plate are the direct working face of the jaw crusher for crushing rocks. The crushing force of the machine is imposed on the rock through the two jaw plates to complete the crushing task. Judging from the current situation, the tooth form of the jaw plate is different. The tooth form of the jaw plate has great impact on the production capacity of the jaw crusher.
 Different jaw crushers have different tooth forms of the jaw plates. Now we will talk about the tooth forms of the jaw plates in terms of tooth height, angle of the tooth form, and the number of teeth.  Like other types of machinery, the jaw crusher has its own characteristic parameters, such as noise, unit power consumption, production capacity, product granularity, in which the production capacity is main parameters. Some manufacturers have carried out the trials of the crusher, but they can only do some estimates on the production capacity due to the limits of experimental conditions and means. After the high-level test of Henan Hongxing Mining Machinery for the production capacity of the jaw crusher, we find that the rotational speed of the machine and shape of the crushing chamber have an impact on the production capacity of the machine besides tooth forms of the jaw plates.
No matter what kind of tooth, the final results will cause the bend and shear of the rock. In this experiment, the compressive strength is 80 ~ 120MP. There are two types of tooth forms: triangular teeth and trapezoidal teeth. After the experiment, we can find that  the trapezoidal teeth is more wearable than the triangular teeth. The physical properties of the triangular teeth are better than that of trapezoidal teeth.
