Mainly the stone crusher sector sector could be divided in 3 classes little, medium and massive. The standard characteristics of every class of stone crushers are briefly talked about below.You will find distinct types of compact stone crushers in numerous states with a manufacturing capacity ranging from 3 to twenty five TPH. Typically, the models getting only one particular Jaw type crusher made use of as primary or secondary crusher in addition to 1 or optimum 2 screens are grouped as compact stone crushers.Commonly people crushers having than one particular crusher i.e., one particular main and one particular secondary or one/two main & two secondary crushers together with a single or more vibratory screens are categorized as medium size crushers. The mined stones are transported mostly by trucks/dumpers and unloaded in to elevated stone wells. The stones are fed by gravity to main crushers. The Crushed stones are conveyed to vibratory screens. The screened products of numerous sizes are conveyed to stock piles by belt conveyors. The oversize is returned to secondary crushers for further crushing and back to the vibratory screen. Such type of medium type crushers have a production capability in the range of twenty five - 100 TPH.Individuals crushers typically having two or more numbers each and every of primary, secondary & tertiary sort crushers with at least 2 or more vibratory screens with mechanized loading, unloading conveying operation s and producing more than 100 TPH crushed stones are categorized as substantial crushers. Generally substantial stone crusher are owned by bigger construction companies like L&T, Dodsal Construction, etc who have their own huge construction projects demand. Such crushers have a capability range of 100 -200 TPH. These type of crusher normally have their own/leased open-cast stone mines and a fleet of mechanical mining equipment , trucks and dumpers, loaders etc. These crushers involve high capital investment and mostly operate round the clock. All conveying operations are done through proper belt conveyors.You can find huge variations in the forms of rock crusher setup across the country depending on geographical locations, type of demand for crushed products, closeness to urban areas, type of raw material, availability of plant and machinery locally etc.
Changing Developing Manner for Coal Mine
The coal resource exploiting produce vast high carbon product on 1 side, on the other side, it caused mine area ecological pollution with environment waste such as vast waste water, gas and slag in producing process. The ejected gangue will have spontaneous combustion, which eject vast toxic gases and greenhouse gases. The exploiting causes land dig and loss. The collapse land directly pollutes environment. For a long time, the mine business gives us a reflection that gangue pile high, earth surface is loss and collapsed as well as polluted water running all around the mine, etc.It is become the conjunct developing direction in international society to develop lower carbon economic climate with scientific supporting. And coal mine is generally produced by high carbon company, so it's a fantastic question to adopt lower carbon economic climate development, which require immediately solve.Coal market develops at the cost of destroy ecological environment. So, the key point for coal market lower carbon developing is changing developing manner, which is scientific developing. We should obey the rule of reduced carbon economic climate and recycling economic climate design and demand with its new manufacturing managing ways, which respects on the following six aspects
1. Increase innovation of mining geology and exploiting technology too as resources utilization rate;
2. Strengthen analyzing of mine area water resources and protect mine water compound handling and utilization to achieve water resource protective exploiting and mine water zero emission.
3. Strengthen reclamation management of coal mine area ecological environment and restoration, achieving mining simultaneous with management.
4. Adjust industrial structure, increase beneficiation, pit power generation and mine waste compound utilization and achieve recycling economy.
5. As a whole new developing pattern of lower carbon economy, lower emission is not only the strategic choice, but also is the option for mine business with continuous develop. We should change high energy consumption, high pollution and very low efficient developing model into lower energy consumption, low pollution and lower emission developing method. And the first developing manner choice will be resource saving, environment friendly reduced carbon developing pattern;
6. Increase innovation of underground mine filing technology and decrease coal gangue occupying area and environmental pollution.
Low carbon economic climate is a superb progress from industrial civilization to ecological civilization. The building of lower carbon ecological mining is combine put human environment, ecological environment, resource environment and technology economic environment with each other.Rebuild the mine exploiting with low carbon and environmental industrial system at minimum cost to achieve maximum resource and economic climate profit. After the extracting, utilizing minimum end management make mine engineering and ecological environment as a whole.
