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 24' by 36', a 56 x 56 jaw crusher has a opening of 56' square. Primary jaw crushers are typically of the square opening design, and secondary jaw crushers are of the rectangular opening design. However, there are many exceptions to this general rule.
A Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw, mounted in a 'V' alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the 'V' aligned jaw plates is the crusher product size gap, or the size of the crushed product from the jaw crusher. The rock remains in the jaws until it is small enough to pass through the gap at the bottom of the jaws.
Jaw Crushers are designed to impact on a rock particle placed between a fixed and a moving plate (jaw). The faces of the plates are made of hardened steel. Both plates could be flat or the fixed plate flat and the moving plate convex. The surfaces of both plates could be plain or corrugated. The moving plate applies the force of impact on the particles held against the stationary plate. Both plates are bolted on to a heavy block. The moving plate is pivoted at the top end (Blate crusher) or at the bottom end (Dodge-type crusher) and connected to an eccentric shaft. In universal crushers the plates are pivoted in the middle so that both the top and the bottom ends can move. ball mills:http://www.hx-crushers.com/p72.html
The Blake crushers are single or double toggle drives. The of the toggle(s) is to move the pivoted jaw. The retrieving action of the jaw from its furthest end of travel is by springs for small crushers or by a pitman for larger crushers. As the reciprocating action removes the moving jaw away from the fixed jaw the broken rock particles slip down, but are again caught at the next movement of the swinging jaw and crushed. This process is repeated until the particles sizes are smaller than the smallest opening between the crusher plates at the bottom of the crusher(the closed set). For a smooth reciprocating action of the moving jaws, heavy flywheels are used in both types of crushers.
By 2010 there were 18 enterprises in China with more than 10Mta cement capacity. The CCA states that some 253 production lines started construction in 2011 and are scheduled to come online in 2011-12, adding 318.4Mta of clinker capacity. By end-2012, China’s total clinker capacity will be 1.574bnta and cement capacity will reach 2.581bnta, according to CCA estimates.
Credit Suisse expects cement production to grow at 3-4 per cent to meet national economic needs during the period of the 12th Five-Year Plan. This means that maximum market needs will reach 2.4-2.5bnt in the next 5-10 years, according to the CCA. In 2011, China produced 1.87bnt of cement reports the CCA, while clinker production rose to 1.15bnt. Seven provinces recorded cement output above 100Mta.
It had seemed that China was immune to the turmoil occurring in the rest of the world’s economies, but it too is starting to feel the effects of a slowdown from the extreme growth patterns it has generated in the last few years. It is paramount that the cement industry is ready for the adjustment, because when construction orders do fall off, cement orders will be next to suffer.
Government funding for infrastructure projects, social housing and water conservation are assured, but they are leading growth at a faster rate than is really required. In essence, by implementing its five-year, government plans to stimulate growth. The government’s strategy distorts the level of true demand and sets its own agenda. However, when housing demand is supplied more than twice-over, the industry has to react by decelerating construction for demand to catch up.

A major question that the industry must face is how sustainable is the continued increase in domestic cement capacity? Even the MIT can see it is not sustainable and has put a cap on the amount of new capacity projects to bring them under greater control. Stricter regulations over emissions are also set to come in as the cement industry is reformed and outdated capacity is removed.
One also wonders how easy it will be for the top 10 producers to forward their plans for consolidation with a forecast slump in domestic construction in the not too distant future. Depending on how easy finance is to obtain through bank loans and share offerings, the path that Anhui Conch has taken to expand its cement production base overseas might well be an example that other leading Chinese producers could yet follow in greater numbers.
It will be intriguing to see what delegates attending the 13th China International cement Industry Exhibition and Conference in March will feel about the latest trends in the Chinese cement sector and if there are many solutions offered. We hope to see you there.
A conventional conveyor for conveying granular material comprises a tube and a hopper. Guide members guide the belt from a flat orientation as the belt leaves the lower roller into a cupped orientation as the belt enters the hopper. The conventional overland conveyor is limited in ability with respect to gradient and alignment curvature. However, there are two less-traditional conveying systems worthy of evaluation against conventional conveyors for long-distance, large-capacity installations, the Cable Belt and the Ropecon System.
The conventional troughed overland conveyor belt is a proven technology that has been used to transport bulk materials for nearly a century. The invention of the three-roll idler belt configuration for material transport dates back to the 1930s. Since then, the requirements for higher capacities and longer runs have led to innovation and new technologies used in conventional overland conveyors. Although a proven and widely used technology, the conventional overland conveyor is limited in its ability to traverse natural terrain. The effort to overcome this limitation has led to new technologies that offer more flexibility with respect to gradient and alignment curvature.
Options for overland conveying vary according to numerous factors, including capacity, length, terrain, geotechnical properties, and the environment. Overland conveying options include the conventional conveyor, Cable Belt, and Ropecon systems. This section provides an overview of these technologies, with an emphasis on the less traditional Metso and Doppelmayr systems.
Conventional large-capacity, long-distance overland conveyors use a steel cord belt with a single layer of parallel steel cords to carry the belt tension. Vulcanized splices are used to connect belt segments, and are the limiting factors in a belt's carrying capacity. Current findings have led to the acceptance that splice safety factors can be reduced from previous empirical numbers, which had a significant impact on carrying capacity.

There are numerous options for tensioning the belt on a conventional overland conveyor, which allow the system to be very flexible and cater to numerous applications and loading conditions. Current knowledge of dynamic conveyor behavior and take-up control has allowed overland conveyors to be designed with sophisticated take-up management that reduces belt tension and overall costs.
Conventional conveyors are typically driven and braked at one or more locations along the conveyor. The designs, locations, and controls of these drives, combined with take-up and splice technology, have allowed these conveyors to perform. at capacities and lengths inconceivable 25 years ago. Several types of intermediate drives are available, from the tripper style. through the booster style. To the power-strip style, which does not need trippers?
The cupped orientation is maintained by sliding contact at an interface between the lower surface of the belt and the hopper walls as the belt passes through the hopper. Left and right baffle members are attached along the hopper side walls and thereby prevent the granular material from sliding down the hopper walls into contact with the interface between the lower surface of the belt and the hopper walls. The belt has a width that is substantially fully exposed to granular material entering the hopper. A method of increasing the capacity of a conventional conveyor comprises reducing the width of the flashing covering belt side portions.
The river sand washing is becoming worse and worse, the government unveils fresh policy to prohibit the washing phenomenon, but the market demand for sand is too large, so that more and more artificial sand are needed to be manufactured. And the high efficient sand washer is the irreplaceable equipment in the sand making production line. The high efficient sand washer is used for washing the impurities out of artificial sand and thereby produces high quality artificial sand.
The man-made sand is not easy to be manufactured because the raw material needs to be crushed by the jaw-type crushing machine at first, and then secondly crushed by the sand maker, and in the end the coarse crushed sand will be cleaned by high efficient sand washer. The standard final fine sand will be used in construction and other places.
The finished product has rough surface and multi-edges, and it is easy to mix with cement to form high quality aggregate. The concrete strength is higher than natural one. It is used for solving the powder content problem in sand making process. So this machine is the key equipment in the artificial sand making production line. The later half of this year, influenced by the country's macroeconomic impact, the infrastructure developed slowdown, real estate environment is not very economical, and the mining equipment industry is closely related with real estate and infrastructure investment.

In a questionable economy, when everyone is turning to new avenues for employment, it’s not surprising that environmental awareness has opened some fantastic opportunities. One of the hottest trends has been consultants that specialize in advising companies on the various aspects and choices of sustainability. More and more companies are going green but typically just don’t have a clue where to start. Sustainability consultants step in and not only offer guidelines but show corporate America how they can save money in the process.
When a company decides that they want to go down the path of sustainability, they quickly realize that there are all kinds of compliancy and regulatory requirement hoops that they have to jump through. Making the right sustainability choices for the company also involves some financial investment with the requirement for either a long term or short term return-on-investment goal.
Happily, there are now educational courses that are available for an individual to extend their knowledge base and become a sustainability consultant. Some courses are available in a standard college setting, but there are many more that are available online. The demand for these types of specialists is growing exponentially. Companies now know it makes good business sense to show the public their green intentions and they can’t get to that level of success without the assistance of sustainability consultants. As the professional manufacturer of complete sets of mining machinery, such as cement plant, Henan Hongxing is always doing the best in products and service. rotary kiln:http://www.hx-crushers.com/p66.html
A good sustainability consultant will be equipped with a number of tools of the trade that they learn in the educational process. These tools will be based on the direction they are heading in, the companies they are assisting and both Federal, State and Country guidelines that are required for compliance. They will have to brush up on all costs and have bottom line templates to be able to whip out with the kind of results and expected ROI that the board of directors will want to see. If you specialize in one particular field of sustainability, you will also want success story examples and contacts that will be shown on the display slides. If you think about this paragraph, it’s not that much different than the expectation level involved in any project that is proposed in any business on a daily basis.
Becoming a sustainability consultant is positions that will help a company make a climate change direction for their business. The fact that they have you on board is the first major hurtle, because they are already looking forward to the savings they can get and the positive affect they will have on the earth. That, in itself, is an accomplishment because you don’t have to sell yourself; they already believe in the direction.

The processing of iron ore is a task that involves taking the raw ore and preparing it for use in the creation of a number of different iron products. There are actually several different processes that may be used to aid in this conversion of the raw ore into useful iron components. Most processes will involve some sort of crushing and grinding activity that results in small units that are easier to work with in terms of creating iron bars or even preparing the iron for smelting.
In most cases, the processing of iron ore will begin with some sort of crushing action. Different types of crushers are in common use today, including jaw crushers, impact crushers, hammer crushers, and cone crushers. Each of these types of crushing equipment are designed for use in specific situations involving the processing of iron ore. For example, hammer crushers are often used at mine sites when the yield from iron ore deposits is somewhat small.
After use of some form of crushing equipment, the processing of iron ore will usually involve grinding. Different types of grinding equipment produce everything from a fine dust to small pebbles, with the choice of grinder based on what type of further processing is involved to prepare the ore for its intended use. The grinding can sometimes occur at the site immediately after the crushing is finished, or take place in a processing plant in the event the yield from the excavation is more than can be managed with the smaller equipment designed for use at a mining site. As the professional manufacturer of complete sets of mining machinery, such as flotation cells, Henan Hongxing is always doing the best in products and service. ball mills:http://www.hxjq-crusher.com/20.html
Once the crushing and grinding are complete, the processing of iron ore will often involve some sort of filtering action before the final product is created. Filtering equipment will help remove any other types of rocks or other impurities that were not screened out during the early processing efforts. The end result is a raw iron ore product that is ready for smelting and the manufacture of iron goods and products that can be used in a number of different applications.
The main goal for the processing of iron ore is to take the ore extracted during the mining effort, break the ore into usable units and then purify those units before the actual smelting begins. Doing so makes it easier to produce a higher grade of iron that in turn can be used to create materials for use in everything from manufacturing lawn furniture to cookware to building materials. Typically, whatever processing is done must comply with governmental regulations that set standards for the type of iron that may be used in the manufacture of specific types of goods, especially iron products used in the creation of machine components or in materials used for building construction.
Factors affecting the magnetic separation process
Magnetic effect of many factors, impact crusher in India the magnetic separator is the following:
1) Magnetic separator cylinder rotation;
2) Magnetic system angle;
3) Work space (ie, jaw crusher in India Park tube and the bottom of the gap);
4) Pai concentrates at the gap.
The size of the number of revolutions of the magnetic separator effect
Generally speaking, cone crusher in India the small diameter of the magnetic separator using high number of revolutions, e.g. Φ600 mm diameter with 40 rev / min, the diameter of the low number of revolutions, such as Φ750 mm diameter 35 turn / sub.
The size of the separator speed processing power. Have a certain impact on the quality of concentrate. Rpm high magnetic separators in operation, due to faster magnetic smaller with the living body and gangue up opportunities, and only those magnetic high mineral particles may sorting up, and thus the quality of concentrate higher. Contrary rotation is relatively slow; due to the magnetic induction effect of the magnetic weaker mineral particles also have the opportunity of sorting up, resulting in the quality of concentrate affected. Therefore must be based on the ore characteristics, specifications, select a suitable magnetic separator rpm.

The magnetic declination size of the magnetic effect
Production by the State, magnetic separator, magnetic declination by the shaft of the transmission side of the head is equipped with indicating device, move the adjusting nut can be adjusted to the size of the declination of the magnetic system.
Magnetic declination angle is too small is not good, too small affect the quality of concentrate, so that the magnetic properties of small particles have the opportunity to sorting up, but the tailings grade will reduce the recovery rate is good; the angle is too large, have the opportunity to choose up to improve the quality of concentrate is good, because only the magnetic particles, magnetic there is no chance to come up into the tailings, the tailings grade increased, lower recoveries.
Therefore, the magnetic declination size is the number of appropriate must be based on operational requirements to adjust the general production field magnetic declination adjustment around 15 ° -20 °. Adjusted the angle of the magnetic system in production, if the operating conditions and requirements did yo change, Do not just move.
