As the regular exchange jaw crusher parts, it is the most important things that how to decrease the replacement cost of crusher jaw plate. There some advice for customers:
Choose the right time to rotate the jaw plate
The ideal situation would be when even wear occurs throughout the jaw plate area, using all the manganese teeth, eliminating the need to execute the “turn”, or change production. This is impossible, however, because there are areas where we cannot avoid more severe wear than in others, mainly because of the crushing movement geometry, such as in the fixed jaw plate lower tip and the central area of the swing jaw plate, so a turn should be carried out to achieve better performance and use. We recommend a double turn, in other words:
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.
Choose the right time to change the jaw plate
Choose the right time to change the jaw plate, too soon and you don’t get the value for the cost of the liner, too late and you suffer from significant production losses.
For example Your production rate: 200 tons per hour of sellable? minus Crush Margin $2.50 per ton-hours per day 10 production hours per day. A 10% reduction in production results in a loss of $2,000 per day in gross profit. Under this working condition, one week you will lose $14000 which match a set new jaw plate price. So you need to have an accurate belt scale, plan your liner change and do it no later than when you notice a 10% decline in production.
Choose the right material for casting the jaw plate
Some customers need jaw crusher to crush very very hard material, such as cobblestone, bronze raw material stone. The normal manganese jaw plate cannot work a long time, you need to choose the other material jaw plate. Such as our foundry new material –TIC Insert jaw plate
For example:
We have a Nicaragua customer, who has a C125 jaw crusher. Its jaw crusher parts from the local agency, its fixed jaw plate have 7 days working life and movable jaw plate have 14 days working life.
After choose MGS Casting custom-designed a set of TIC insert jaw plates which featured titanium carbide (TiC)inserts in the high wear areas of the manganese alloy jaws. This design improvement increased the wear life, the tic inserts fixed jaw plate span life increase to 15 days and the tic insert movable jaw plate span life increase to 90 days. The fixed jaw plate working life increase to double times, the movable jaw plate working life increase to 8.57 times, however, the cost of TIC insert jaw plate just 1.8 times than normal manganese jaw plate.
