JAW CRUSHER GOOD PRACTICE

SCALP THE FEED MATERIAL
Generally all material smaller than the discharge gap should be removed (scalped) prior to being fed into the jaw crusher. This will increase the tons per hour of total capacity of the plant
Reduce wear on the jaw dies.
Increase cubical product.


CHOKE FEED
Jaw crushers should be fed a consistent rate of feed that will result in the crushing chamber being kept full at all times.
This will result in more stone-on-stone crushing, reducing the wear on the jaw dies. 
Create a more cubical product, and better gradation curve.
Produce more even wear over the length of the jaw dies
 
CHOOSING THE BEST SIZE OF JAW CRUSHER
Buying to the maximum size of rock that might be fed the jaw will result in a jaw crusher that will be:
Bigger than needed for most crushing
Difficult to keep choke-fed
Cost more to purchase than necessary
Cost more to ship
Cost more repair
Cost more to operate

Consider a jaw crusher that will handle 95-98% of the material that might be fed to the jaw.

It will cost less to install grizzly bars over the feed hopper to remove the oversize rocks, or set them to the side, than to buy an over-sized jaw crusher. The largest rocks can then be manually broken, sold as rip-rap or erosion control or landscaping boulders.

OVERHEAD ECCENTRIC JAW CRUSHER


Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.

There are two basic types of jaw crushers
overhead eccentric style (shown above)
double-toggle style
Which will work best for a given operation depends upon several factors.

DEEP CHAMBERED JAW CRUSHERS

•    Deep-chambered jaw crushers will have more rock-on-rock crushing while the feed is passing through, and a better nip-angle.

•    Deep-chambered jaw crushers will typically produce more cubical product and have a longer wear life from the manganese per ton processed.


Below are pictures of a deep chambered jaw crusher and a shallow chambered jaw crusher.

To better meet your needs please provide at least the following information:
1. Maximum size rock you want to be able to run through the crusher?
2. Maximum size rock you want to be discharged from the crusher?
3. How many tons per hour do you want to feed the crusher?
4. Do you want just the crusher, a crusher with feeder, a crusher with support framework, or a portable crusher?
