When a sample arrives it is first crushed and sieved. This is to obtain the correct grain size for the rest of the separation process. The ideal grain size is 0.25-0.50mm. There are two crushing machines available a jaw-crusher and a disc-pulverizer. Samples are usually run through the jaw-crusher first, and then the pulverizer.
Primary Crushing Before crushing the stones down to the wanted shape and size, the stones are broken into smaller sizes, as in the case of mining of crushed stones for civil construction. This stage is performed by a jaw crusher.
Working Principle of Impact Crusher The impact crusher driven by the electro motor, the rotor will rotate with high speed, and when the materials go into the action zone of the plate hammer, they will strike and are crushed on the plate of the rotor, and then are crushed again when they are thrown to the impacting device, and then the materials will bounce back from the impact lining board and ...
A big jaw crusher is a powerful machine that is used for crushing a variety of rocks and abrasive materials such as recycled concrete, granite, or other types of materials into smaller sizes. As far as the design of the jaw crusher is concerned, the designer is relatively rudimentary when compared to other types of crushers available today.
When idling jaw crushers consume approximately 50 of the power of full operation and gyratory approximately 30. Installation of an underground jaw crusher may cost up to six times as much as the crusher itself. A 48 by 60 jaw crusher produces approximately 1.8 tons per horsepower-hour 2.2 tkWh at a 61 reduction ratio.

The crushing equipment needs to have a large feed port and has a strong crushing capacity to be competent. Jaw crusher is the preferred equipment. In order to obtain finer and better gravel or artificial sand, we need medium and fine crushers machine, such as impact, cone crusher
Sep 02, 2019 Jaw crusher units with extra-long, articulated crusher jaws prevent coarse material from blocking while moving all mounting elements of the crusher jaw from the wear area. A more even material flow may be affected if the transfer from the prescreen or the feeder trough is designed so material simply tilts into the crushing jaw.
Jul 25, 2018 The duty of the primary crusher is, above all, to make it possible to transport material on a conveyor belt. In most aggregate crushing plants, primary crushing is carried out in a jaw crusher, although a gyratory primary crusher may be used. If material is easily crushed and not excessively abrasive, an impact breaker could also be the best ...
The jaw crusher works as a curved extrusion, the material is squeezed and crushed in the crushing chamber composed of moving and fixed jaw plate. The impact crusher works as impact crushing, the material is repeatedly impacted and broken between the rotor board hammer and the impact plate. The working principle is easy to understand.

At first, the stone materials are delivered into the jaw crusher for coarse crushing by the feeder. Then, the materials crushed by the jaw crusher will be crushed by impact crusher or cone crusher further. Thirdly, the crushed stone materials are sent to the vibrating screen to separate the stone materials from the impact crusher or cone crusher.
Jaw Crusher. Jaw crusher has a moving jaw plate and a fixed jaw plate, which are wear-resistant and pressure resistant. During the operation, the jaw plate simulates animal occlusion, and the feeding port is large, so it is very suitable to deal with the coarse crushing of large block materials
The gyratory crusher can, just like a jaw crusher, accept boulder sizes close to 1.5 m for the largest equipment.. This crusher can handle products with a Mohs hardness that is not necessarily less than 5. As is the case for jaw crushers, there is not any mutual sliding on grinding surfaces, but simply rolling of the nut on concaves.
