The Development of Crusher has Huge Capacity
To fix a principal crushing plant that has been excavated and built underground is complicated and costly; therefore, careful planning pays good dividends. This paper looks at different aspects of plant design including capacity, installation, layout, maintenance and safety.
This paper concentrates on hard rock applications, however, a few of the findings will apply and also to crushing softer minerals using other than compression crushers, for instance, impact crushers, sizes, etc.
Real estate in an underground mine is usually with a prime cost; therefore, the design of primary crushing plants faces more limitations compared to surface where you could say the sky’s the limit. However, the key crushing and transportation from the ore to come to light tend to be dimensioned so that they define the capacity of the mine; whatever limits the functionality with the plant may limit the output of the mine.
High speed railway is entering the rapid development track, the prospect of a crusher in the high speed railway construction has vast potential. Vice Premier Zhang Dejiang express on high speed rail at the Seventh World Congress, the government has taken the high speed railway as priority of developing strategic emerging industries, which means the government will increase the supportive strength henceforth such as in financial investment, construction land, technology innovation, business environment, etc. The application prospect of the crusher in high-speed railway construction is remarkable.
China is the world ‘s fastest-growing country in high speed railway, and the commissioning mileage and the mileage in building is the longest all over the world at present. As the end of the November the whole commissioning mileage will reach 7531 km, and the in building mileage will be 10000 kilometers above. According to the plan, to 2012, China will build 42 high-speed railway passenger dedicated line, high-speed rail mileage will exceed 13000 kilometers; by 2020 will reach 16000 kilometers above. According to estimates, the next three years, China will invest 900 billion yuan to build 9200 km high-speed rail. So great a high-speed rail construction project, the demand of aggregate will be a huge number, aggregate supply and demand market faces a basically infinite demand space. Large aggregate supply gap needs almost throughout the sand stone field to meet the market supply, also needs a large amount of crushers, sand making machines and other mechanical equipments to support the producing of aggregate. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery, like ball mills, Henan Hongxing is always doing the best in products and service.cement rotary kiln:http://www.hx-crushers.com/p116.html
Planning the crushing plant for maintenance is an important part of achieving high process reliability and availability. Lifting requirements for the major components has been discussed above nevertheless it should also be noted that the routine maintenance includes lifting wear and spare parts, well located jib cranes or monorails will be the answer. In large crushers, perhaps the tools necessary for opening or tightening bolts can get bulky and benefit from creating a lifting device handy.
In stone crushing plant, jaw crusher is used as primary crusher machine, when big stones are crushed smaller after jaw crusher, they are transferred to impact crusher or cone crusher for secondary crushing, then go through the stone shapping machine for getting cubic size. Using screening machine to screen out the suitable stone aggregate,stone crusher, while the unsuitable stones return to the crusher machine fro re-crushing.
