In brief jaw crusher is mainly used for crushing coarsely that means its crushing size is relatively large. Impact crushers are secondary crushing machines and the two kinds of stone quarry machines are mainly used to crush lagre and medium-sized stones. And impact crushers are the main machine in the sand processing equipment. Moreover Jaw crusher can process almost all kinds of materials but impact crusher

Jun 01 2018nbsp018332Material breaks to fill the air pockets or voids in the crushing chamber. Impact crushing. Impact crushing is when the material is hit or thrown. This crushing process uses the theory of mass and velocity to reduce the feed material. Therefore the faster the speed of the crusher
Sep 02 2019nbsp018332Impact crushers are increasingly used for crushing recycling material. Impact crushers are capable of producing mineral aggregate mixes in one single crushing stage in a closed-cycle operation making them particularly cost-effective. Different crusher units can alternatively be combined to process recycling material.

Efficiency can be defined by the ratio of work done by a machine to the energy supplied to it. To apply what this means to your crusher in your reduction process you are producing exactly the sizes your market is demanding.
In the past quarries produced a range of single-size aggregate products up to 40mm in size. However the trend for highly specified aggregate has meant products have become increasingly finer. Currently many quarries do not produce significant quantities of aggregate coarser than 20mm it is not unusual for material coarser than 10mm to be stockpiled for further crushing.
The following are tips and best practices to keep your site crushing efficiently and reduce the number of fines produced.
A jaw crusher is a compression-type of crusher. Material is reduced by squeezing the feed material between a moving piece of steel and a stationary piece. The setting or the space between those two pieces of steel controls the discharge size. The tighter the setting the smaller the output size and the lower the throughput capacity. Jaw crushers are mainly used in primary crushing they are rarely used as a secondary crusher.
As compression crusher jaws generally produce the coarsest material because they break the rock by the natural inherent lines of weakness. A jaw crusher can be an excellent primary crusher when used to prepare rock for subsequent processing stages such as washing classifying or a secondary crusher.
Try to choke-feed any compression-type crusher. Remember we are using gravity and the weight of the material to push or force material through the chamber. Since in a compression machine the material breaks to fill the air pockets or voids in the chamber a non-choke chamber will produce a slabbier output than a choke-fed chamber.
Jaw crushers are routinely choke-fed as this maximises production capacity and ensures particles are uniformly broken. This promotes stone-on-stone crushing which breaks up flaky or slabbier particles. If you are seeking fewer fines trickle-feeding material into the jaw crusher could achieve this however this would have an adverse effect on particle shape and would also reduce throughput capacity hindering the crusherrsquos efficiency.
Ideally the feed rate should not be switched from choke to non-choke as this would cause problems downstream at the secondary processing plant. In practice many jaw crushers are fed in this intermittent fashion due to gaps in the delivery of feed material from the quarry. Jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed side setting CSS.
In practice many jaw crushers are not fed to their design capacity this is because the subsequent processing plant does not have sufficient capacity to handle the volume of material that would be produced if the jaw crusher were working to capacity.
