Under the system of market economy, the competitions among all enterprises are fiercer and fiercer. On the basic of keeping product quality, the comprehensive product cost is more reasonable and lower, and the product competitiveness is stronger together with the longer product prosperity period. Thus the enterprise will be more powerful. For example, most enterprises try to lower production cost of iron ore to grasp the chance to expand the interests.

It has a great crushing performance in the work of medium-size crushing, fine crushing and super fine crushing. The crusher is the improved type of spring cone crusher and can be used to replace ordinary hydraulic cone crusher in the field of mining and construction. It is the most ideal equipment for large stone crushing factory and mining industry. As the professional manufacturer of complete sets of mining machinery, such as stone jaw crusher, Henan Hongxing is always doing the best in products and service.
If the equipment manufacturing industry upgrades, research-and-development-oriented enterprises will benefit. We think that the comparative advantage of the labor cost in China machinery industry is disappearing, so the upgrade of equipment manufacturing industry is the only way to success. At present the r&d investment is only that of about 2 percent for the 204 listed enterprises in our country machinery industry. But according to the fact that In America the R&D fees reach 6 percent for the 245 listed mechanical enterprises, the research and development investment of China machinery industry is insufficient. Looking from the American development experience, if an enterprise increases its r&d investment dramatically, its business performance and the profit level will improve greatly in the next 5 to 10 years, and excess returns of these listed companies is also much higher than that companies with less investment.
The tax credit for new turbine projects
expires at the end of the year. Its fate is uncertain amid the
negotiations between lawmakers and President Barack Obama to avert the
"fiscal cliff," a series of tax increases and spending cuts due to kick
in next year.
Grassley has backed the credit, known as the renewable energy production tax credit,
since it was established in 1992. It also is available for other kinds
of renewable energy, including geothermal, solar, hydropower, biomass
and tidal.
Grassley voted in August for a bill to help wind
companies by letting them take the credit at the start of construction,
rather than when new turbines are finished and connected to the energy
grid. The bill won approval in the Senate Finance Committee, but it has
not come up for a full Senate vote.
Lobbyists, analysts and
congressional aides said they doubted the bill - which would greatly
increase the cost of the credit to taxpayers - could pass either the
Senate or the House of Representatives.
A lobbying fight has
emerged over renewing the credit at its present level, pitting backers
such as NextEra Energy Inc, the largest U.S. wind energy producer,
against rivals such as Exelon Corp, the top U.S. nuclear power group.
Equal
to 2.2 cents on each kilowatt-hour produced, the credit poses a
competitive threat to utilities like Exelon that rely chiefly on
traditional power generation, analysts said.
Exelon generates wind power and has claimed the credit, too, but NextEra owns many prime U.S. wind facilities, analysts said.
Wind advocates said they need the more favorable tax credit
in 2013. If the credit is extended at its present level, "we don't see
many wind projects being developed in 2013," said NextEra Executive
Chairman Lewis Hay in an interview.
Hay declined to comment
specifically on the company's expansion plans if the credit is extended
or not. The company claimed about $147 million of wind tax credits
through the first nine months of 2012, according to regulatory filings.
A one-year extension of the current credit is "unlikely to spur a lot of wind development in 2013," said Matthew Kaplan, wind energy analyst at IHS Inc, an economic research firm.
The efficiency of solar power plants – including photovoltaic (PV)
and solar thermal technologies – depends on how closely the collectors
are able to track the course of the sun. The more precise and
trouble-free these collectors operate, the more efficient and therefore
more profitable the plants will be.
Rolling and plain bearings, as well as linear units from Schaeffler are making an important contribution here.
These units have high rigidity and high load carrying capacities and
operate reliably even under extreme operating conditions. With its
extensive range of products and specialist expertise for materials,
coatings and seals, Schaeffler is an important development partner and
supplier for projects that involve parabolic troughs, solar towers, Dish
Stirling systems and Fresnel power plants.
In addition to standard bearings, engineered solutions for specific customer requirements are
also provided. Depending on the type and design of power plant,
suitable rolling bearings include slewing rings, angular contact roller
bearings, ball screw drives, housed units and radial insert ball
bearings, as well as track rollers. Plain bushes, spherical plain
bearings and linear units are also provided.
Schaeffler has
expanded its range of plain bearing solutions for solar energy
applications. As well as ELGOGLIDE plain bearings, which have proven
themselves over several years now, the product range also includes
metal-polymer composite plain bearings and ELGOTEX plain bearings.
ELGOGLIDE is a sliding layer that comprises a technical woven material with support fibres,
Teflon fibres and a synthetic resin matrix. The advantages of these
bearings are that they are maintenance-free units and offer very high
load carrying capacities, particularly if very high loads are present on
one side combined with swiveling movements.
The unique characteristics of metal-polymer composite plain bearings come from the composite material,
which enables low wear sliding characteristics, as well as high load
carrying capacity and good thermal conductivity. The excellent
formability of the material also enables customer-specific components to
be engineered for various rotary, linear and swivel motions.
The composite materials
used for ELGOTEX bearings are resistant to corrosive media and offer
continuously low friction, low wear sliding characteristics, ensuring
maintenance-free operation. ELGOTEX comprises two intertwined, wound
layers. The internal sliding layer – which is embedded in a resin matrix
with fillers and solid lubricants – is made from synthetic and PFTE
fibres. The external layer comprises continuous glass fibres (filament)
in epoxy resin. A specific winding angle of the glass fibres stabilises
the layer, which significantly increases the strength of the plain
bushing.
Crushing and screening equipment used to produce the majority of coal in the United States because it is cheaper than underground mining. Open pit can be used in charcoal buried less than 200 meters underground. In mining, giant machines remove the top layer of soil and rock layers to expose a large bed of coal. After extraction is complete, the mud and rock back into the pit, the topsoil replaced, and the area replanted. The land can be used for agricultural land, wildlife habitat, recreation, offices or shops.
Underground mining, sometimes called deep mining is used when coal is buried several hundred feet below the surface. Some of the mine is 1,000 meters. To remove coal in these mines, miners ride elevators in deep mines where they operate machines that dig coal.
After coal comes from the earth, as a rule, on the assembly line in the preparation of the plant, which is located at the mine. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of coal.
When raw coal is dug from the coal fields or jaw crusher to crush the sales of small to large aggregates of coal, a process commonly referred to as the primary crushing process. Coal large aggregates are not used, so that impact crusher is used to crush aggregates into small particles of coal, such as the size of Pebble. Due to certain coal producers must produce charcoal dust. As a professional manufacturer of crushers, SBM can also supply shredders. Milling of coal used in the grinding of coal in accordance. Take a hammer for example, many small scale producers of coal to a hammer mill. He is able to grind coal 0 ~ 1 mm or less. Production line for large coal cars LM series grinding their requests, and it is good to avoid the dangerous flammability. Details of grinding machines that are used in coal grinding depends on the construction of coal production line.
