Jan 22, 2016 The feed to a crusher should not contain an excessive amount of fine material this could be stated a little more definitely by saying that it should not contain an excessive amount of material smaller than the crusher product size. Just what constitutes an excessive amount depends of course upon several factors, chief among which are the design of the
Accumulation of fine material in the crusher discharge chute Bridging due to Oversize feed material Excessive clay or other fines in the crushing cavity
Oct 22, 2015 If the ore feed to any gyratory or jaw crusher consisted entirely of large cubes or spheres of a size that would just barely enter the crushing chamber, the crusher could not be expected to produce anything like its normal rated capacity because the upper part of the crusher could not shatter the large pieces enough to keep the rest of the crushing chamber busy.
The Jaw Crusher is designed to handle this feed, but limits are Do not exceed the F80 rule on top size. This happens at times, just not a steady rate. The fine material size equal to the closed side setting should be removed prior to entering the crushing chamber. A best practice, if possible, is to blend the material arriving from the source.
The crusher should be shut off and isolated before considering the use of bars and hand hammers. Careful consideration should be given to the risk of large pieces of feed material moving and causing trap or crush injuries. Wedges should not be used due to the risk of them becoming a projectile (This has caused fatalities in the past).
Jun 10, 2020 Fine material in feeding into the stone into the crusher, the particle size is equal to or less than the material set at the edge discharge port.according to experience, for the secondary cone crusher, the content of fine material in the feed should not exceed 25three - stage cone crusher feed of fine material content should not exceed 10.
Provided screen decks are correctly selected, the moist fine material in the incoming ore tends to be removed in the screening stages and therefore does not enter into subsequent crushing units. All crusher cavities and major ore transfer points should be equipped with a jib-type crane or hydraulic rock tongs to facilitate the removal of chokes.
Nov 01, 2009 Organic materials such as humus, wood or clay should not contaminate the final product and must therefore be separated completely before crushing takes place. These can be eliminated with so-called heavy product screens in front of the crusher because impurities occur mainly in the fine material.

If the material feed is not a hard rock application, is not abrasive, has larger lumps of material or a small amount of harder inclusions and fine material generation is not an issue, a Rockertooth Crusher may be a good option. If the material to be crushed is hard rock or is abrasive, a Sample Jaw Crusher should be considered.

Jan 01, 2019 The Stag jaw crusher, shown in Fig. 5.4, has a fixed jaw and a moving jaw pivoted at the top with the crushing faces formed of manganese steel. Because the maximum movement of the jaw is at the bottom, there is little tendency for the machine to clog, though some uncrushed material may fall through and have to be returned to the crusher.

Fine granular material can usually be screened away. Grizzlies or screens directly below the primary crusher have been used to allow finer materials to pass through and separate from the coarser material that comes out of the crusher. A primary concern is that materials are not picked up on the grade or at the crusher site that should not ...
The first link was of a crusher cheating they were breaking slate But keep in mind crushing (as Natasha will probably assert as well) has more to do with jaw opening then anything. A 2 x 2 foot jaw crusher set at 1 inch is going to be slow, where as a 12 x 12 inch jaw crusher set at a 4 inch opening is going to be 10 times faster.
