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 the …

The crusher is a jaw type so it is very similar to any other jaw. The main difference is that I can change the angle while crushing and can dump out any jams that may occur (most of the time). Our feed material does not usually have rebar in it, and if it did, the machine could crush regardless.

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.

Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are ...

Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

The maximum feed size is approximately 8 0% of the feed opening. The open side setting is measured when the crusher is at rest. The setting is measured either top to top, or bottom to top, depending on the tooth profile of the jaw dies. The closed side setting can be calculated by deducting the stroke from the OSS.

Over feeding an impact crusher will actually give the opposite effect of what you are probably trying to achieve. You want greater production right? Then over feeding is not the way to do it. Unlike jaw crushers impactors do not run on the choke fed theory. Jaws and cones need to be choke fed as they work on gravity and compression.

As an indirect jaw crushing parameter, the choke feeding intensity was also emphasized by Beloglazov and Ikonnikov [40]. As the rock comminution and energy efficiency can be defined as a function of area increment of particles in jaw crusher [41], the production of fines can be diminished by regulating the mf in the crushing chamber.
