Choosing the correct jaw profile for your crusher

Choosing the most appropriate profile is not simple and there are no rules, since each application has a number of different variables like feeding, opening, product needs and problems. All these will decide the type and service life of the jaw parts you are choosing.
Certain profile types decrease or increase the crusher’s hourly production. So, for the correct choice, it is necessary to have a good knowledge of crushing and to observe what happens inside the crusher’s chamber (very lamellar material, excessive humidity, fines, need of small opening, etc).
And also the stone type also decide what material you are choosing. As we all know when the same crusher deal with different type of stones, the performance and the service life of the jaw plates are different. Why? some stones are of higher grade of the hardness, some stones are of more silica inside, etc. 
So to choose the right jaw plates material on different worksite is necessary. 

When the wearing of the jaw plates is severe, it is a known fact that crusher performance is not ideal, because the empty spaces between the teeth are reduced, encagement happens frequently, the crushing angle is changed or, in other words, production is affected.

This means that, a cost-benefit analysis for changing the worn jaw plate should be seriously considered, because at a certain point, the difference in production justifies the investment in a new part. We have also observed users crushing even with cracked and perforated jaw plates, without carrying out the correct control and cost x production analysis.
To change the jaw plates in time is a very very important thing to do the good maintanance. And will cause to very bad effect if we don't change the jaw plates when it's time to. 
Fixed jaw plate – use until wear of about 50% occurs in the lower area and make the first turn. Make the second turn when wear from 90% to 100% occurs in this new lower area. Conclude using the remaining 50% of the life cycle of this extremity.

Swing jaw plate – the same procedure is applied to the swing jaw plate, because although the wear occurs in the central area, it rarely occurs in the exact middle of the jaw plate.

Throne parts use only good material to ensure the best possible service life for the jaw plates, and meanwhile make the best machining to ensure the perfect matching with your jaw crusher. Customerized manufacturing also accepted.
