Choke feed is considered to be material located 360 degrees around the crushing head and approximately 6" above the mantle nut. Maximum feed size is the average of the open-side feed opening and the closed-side feed opening. ... Low speed: Secondary applications, after a Jaw Crusher; Medium speed: Gravel applications with coarse feed ...

A fixed jaw, mounted in a V-shaped alignment, is the stationary breaking surface, while a movable, "swing" jaw exerts force on the feed material by pushing it against the stationary plate. The space at the bottom of the "V"-aligned jaw plates is the output gap that dictates the size of the crushed product from the jaw crusher.

The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It …

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 …

Still using the 32 x 54 Jaw Crusher example, the top size of the feed entering the crushing chamber has to follow the F80 rule that 80% of the top size feed material is smaller than the gape opening. Using the F80 rule with the 32 x 54 Jaw Crusher, the 32" gape opening equals a 26" top sized feed, and with the 6:1 ratio of reduction, the ...

1. Keep the crusher choke-fed. Choke feed means to keep the head covered with at least 150mm of feed material. Conditions that help keep the crusher choked include surge bins, bin level sensors, adjustable speed feeders, and automation. 2. Stable, continuous feed. The gradation of the feed material should be continuous from …

Here is what a well choke fed jaw crusher looks like! Too many mines run these jaw crusher cavity like a funnel without any choking. Operators must keep the jaw's cavity …

crushers need a choke feed to utilize rock-on-rock crushing. And to main-tain a choke feed, the crusher must have the correct liner for the feed material. If coarse material is fed to a cone with a fine liner, the liner will wear unevenly near the top of the man-ganese. A feed that is too coarse will also result in low tons per hour, a

Feeding Your Jaw Crusher. Jaw crushers are often choke-fed to maximize production speed. Choke feeding results in stone-on-stone crushing, which can help break apart more flaky materials. However, choke feeding also often results in a finer output. ... This is because jaw crushers typically feed into secondary processing that will have a ...

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.

Osborn explains that operators can gauge their return by shutting off the raw feed to the cone and analyzing what is returning to it as recirculated feed. "If you're making 3/4-inch aggregate and the cone is set at 1-inch, you're not using it well," he says. "If you're making 3/4-inch or 5/8-inch material, don't set the cone at 1 ...
