Jaw crushers are a powerful tool for crushing stone or rock. The specifications will differ depending on what type of crusher you are using. One of the primary considerations in the construction of jaw crusher is the metal used for the crushing mechanism. It has to possess a breaking point that is considerably higher than the stone or rock it is attempting to break down.
Jaw crusher is mainly constitute feed hopper, points feeder, vortex dynamic crushing cavity , impeller, spindle, base hammer broken machines, gearing, stent, etc. The analysis of jaw crusher technological process is as following:First preliminary broken the stone materials by the coarse crusher, then the materials transport to the fine crusher by belt conveyor for further broken . The materials into vibrating screen to sieve two kinds of stones after fine crushing. The materials into the crushing mechanism sand which meet the feeding granularity of jaw crusher, another part of the materials will return into fine crushing. Silmultaneous until the granularity material meet the requirements.
With the advantages of small wear, good granularity scrap, simple maintenance and low operating capital, jaw crushers are used in quarries, construction sites and other similar applications to break down large pieces of rock. They are commonly the first step in the reduction process, breaking large rocks into smaller pieces that will be transported or further reduced. Rocks are poured into an opening and funneled between two rigid pieces of metal that are repeatedly compressed to crush the material to bits.mobile stone crusher specifications describe size and capacity. So although jaw crusher is an old type of crusher, it was welcomed by customers both at home and aborad.
Based on years' experience and technology development,stone jaw crusher series are of 9 different models, which can meet most crushing requirements in primary and secondary crushing. Flexible discharge opening setting of jaw crusher allows perfect match with relative equipments.
As an important crushing equipment in mining and construction. The quality and craftsmanship are very important for the quality of jaw crusher. Before you select you jaw crusher, you should pay attention on the quality of accessories, scale of manufacturer, capacity of production, and hope customer will select the most suitable and good quality for their project.
As the professional manufacturer of complete sets of mining machinery, such as Symons cone crusher,Cement making machine, Henan Hongxing is always doing the best in products and service.
