Jaw crushers find a wide application for brittle materials. For example, they are used for comminution of porous copper cake. A Fritsch jaw crusher with maximal feed size 95 mm, final fineness depends on gap setting 0.315 mm, and maximal continuous throughput 250 Kgh is shown in Fig. 2.8.
The locally produced crusher jaws failed because of the presence of large carbides at the grain boundaries and in the grains.
There was no uniform plastic flow when crusher jaws under investigation work-hardened because they did not possess the optimal hardness and toughness required for crushing.
A Jaw Crusher is one of the main types of primary crushers in a mine or ore processing plant. The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws feed opening. For instance, a 24 x 36 jaw crusher has a opening of 24quot by 36quot, a 56 x 56 jaw crusher has a opening of 56quot square.
In martempering conditions austenitic manganese steel had better plastic flows due to a decrease in overall thermal gradient and reduction in residual stresses associated with heat-treatment operations. This gave a better combination of hardness and toughness than austenitic manganese steel in hardening conditions used for the production of imported crusher jaws.
Due to the premature failure of the locally produced crusher jaws, their use in the quarry industry over a given period of time translates to incurring expenses of about 150 more than expected.
Srikanth 7 used a jaw crusher to create37m coal dust particles. Coal samples were obtained from coal mines in addition to some samples from the same source as Thakurx27s samples. They used a Microtrac Standard Range Analyzer SRA and Small Particle Analyser SPA, which measured projected area and hence diameter using laser scattering and diffraction, respectively. The data were combined and plotted on a RosinRammler graph discussed in Chapter 8. Their main findings were as follows.
Higher rank coals produced more total dust lt15m and respirable dust lt7m. Semianthracite coal produced 3.7 times more total dust and 4.2 times more respirable dust compared with high-volatile bituminous coal.

Granite quarry is a pit or some open excavation from which granite is obtained. To obtain granite from a quarry either digging, cutting or blasting process is used. This process of obtaining the stone is called quarrying. Once quarrying is done, the processing of granite starts. The four operations that are involved in the processing of granite are as follows.
This series of jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. They are widely applied to crush high hardness, mid hardness and soft rocks and ores such as slags, construction materials, marble, etc.PE series Jaw Crusher, including primary crusher and secondary crusher, is mainly used for crushing various ores and bulk materials with compression strength not more than 320Mpa into medium-sized grains.
1. This jaw crusher uses motor as its power. Through the motor8217s wheels, the eccentric shaft is driven by the belt and the belt wheel to make the jaw stock move by a regulated track.
2. The angle between the toggie plate and jaw stock will become large as the up of the jaw stock. This will push the movable jaw plate towards the fixed jaw plate,which can realize the multi-crushing of the materials.
