The ore is to be broken down in a jaw crusher to pass through a 11.5 cm screen. The undersize is scalped before feeding to the jaw crusher. Assuming the maximum feed rate is maintained at 30 t/h and the shapes of feed and product are the same and the crusher set is 10 cm, estimate the size of jaw crusher required and the production rate.

Dodge and Universal. These are distinguished by the manner in which the movable jaw is moved in relation to the stationary jaw. In the Blake-type crusher, which is the most common type of jaw crusher, the movable jaw is pivoted at the top so that it has a fixed receiving area and a variable discharge opening.

Choke feed the crusher to maximise output and increase material reduction. Avoid trickle feeding your jaw crusher as it will only wear the lower part of the jaw plates, and you will lose valuable wear life. Avoid overfeeding the hopper to allow the grizzly section to remove fines before the crushing process.

Because of that reason, the choke feeding intensity undertakes the role of crushing efficiency. Since there is no standard approach for the evaluation of choke feeding intensity for industrial jaw crushers (Fig. 1), it is required to figure out the mechanism of choke feeding as a function of feeding size and quantity.

CHOKE FEED THE CRUSHER {{image2-a:r-w:250}}It's important to choke feed your crusher – in other words, always keep it full of material. By choke feeding your cone crusher, your equipment will run smoother and provide more even liner wear, better product quality (shaping) and the most efficient use of power.
