Cone crusher effectively works on construction waste
According to statistics, China produce could 5000-6000 tons of construction waste annually, especially in recent years, the state accelerates the urbanization process, so construction waste produced in inhabitable houses demolition and renovation increased dramatically, which seriously impact on the urban environment.
The technology to deal with construction waste by crusher in China has reached a certain height. Mobile crusher is significantly effective and also very convenient. As we all know, mobile crusher is consists of crushing and screening production line, the main equipment includes jaw crusher, cone crusher,. Compared with ordinary cone crusher, the effect of spring cone crusher on processing construction waste is very prominent.
On one hand, from city environmental considerations, we have to crush construction waste complying with national regulations on urban construction waste disposal, which requires the crusher itself to be environmental protection and energy saving; on the other hand, with the acceleration of urbanization, the production capacity of crusher have to be improved.
Spring cone crusher is in line with the above requirements; it has the most significant effect and can serve in long term; it is of large handling capacity, high production capacity, energy saving, low noise, good sealing and low maintenance costs--it is an ideal energy-saving crusher.

Hongxing mining machinery industry will take its advantages of environmental protection, energy saving, stability, high efficiency and pleasant intelligence in product to lead domestic crusher equipment to the development of high-end road .
Mobile crusher boosts construction waste recycling
Most of the construction wastes are appeared as solid and generated during the process of constructing or repairing old buildings. Because the large complete sets of equipment for construction is the bottleneck to transform construction waste into resources in China's industrial development, therefore, the mining machinery industry should vigorously carry out scientific and technological innovation, research and introduce more new and efficient construction waste disposal equipment to turn waste into treasure, reduce pollution and waste of resources, promoting the future development of green circular economy.
With the continuous progress of science and technology, China's construction waste treatment technology has been successfully applied at home and abroad.

At the same time of recycling of construction waste, mobile crushing station could turn waste into treasure, for example, after being broken, brick, stone, concrete and other waste could used as masonry mortar and plastering mortar to hit the concrete cushion on behalf of sand; Mix with the standard sand, crushed waste concrete blocks can be used as mortar fine aggregate to plaster wall and ground; it can save energy and resources to achieve clean production and make closed circular economy industrial chain, protecting human environment, what’s more, promoting the path of the virtuous cycle of sustainable development. More importantly, the construction waste disposal industry as an emerging industry, can enable enterprises to achieve economic and social benefits in the pessimistic economic situation, creating the greatest wealth. Having solven the outstanding issues of environmental pollution caused by the construction waste, mobile crusher turns the buildings garbage waste into treasure, promoting new ways of construction waste disposal towards a sustainable development.
Advantages of new heavy construction machinery
Salt has long been a kitchen essential. In fact, many of us can't imagine a meal without it. If food is bland, it's the number one spice to turn to. But how many of us know how salt is actually acquired? How many of us think beyond choosing the most inviting packaging at the local supermarket?
In fact, salt mining is a complex procedure that can take two forms: deep shaft mining and solution mining. Both involve removing salt that lies in ancient underground seabeds that have been buried over many thousand years of tectonic changes to the Earth's surface. The former sees shafts sunk down to the floor of the mine where "rooms" or caverns are then created by blasting and drilling. A conveyor belt lifts the crushed salt to the surface. Most of the salt acquired in this way is sold on as rock salt.
The type of heavy construction machinery now being used is different from years ago in that it requires a specially trained operator. Although some equipment or vehicles such as boomtrucks or forklifts can generally be operated by anyone who used an older model but many of the new machinery is automated due to computerization. Therefore, to work with heavy construction machinery properly and safely requires a trained individual.
To operate the majority big construction machinery used today, operators complete some type of apprenticeship program although paid training programs and on-the-job training options are also available. As heavy construction machinery continues to evolve and become more high-tech and with this type of equipment used for so many different industries and jobs, demand for trained operators is high.
When you think of heavy machinery you usually also think of noise, sweat, hard work and the dust that is stirred up by working it. But new technology has been at work to reduce the many problems associated with working machinery. Years ago, operators had to be strong to survive a day in the heat bumping over rough ground and listening to the roar of all their heavy machinery. But these days manufacturers have realized that operator comfort translates to better efficiency and thus to increased work and a higher dollar return for the employers.
So instead of drivers having to endure grueling heat or icy cold weather day after day, machinery is now equipped with air-conditioned cabs. The noise level has also been reduced where possible by better design and more efficient parts. Much heavy machinery is now comes with electronically controlled systems that take all the hard work out of the actual operation.

Taking innovation on construction machinery
Construction machinery performs multi various tasks mostly using hydraulic power. Some of the recent innovations in the construction machinery industry carry fully computerized hydraulic control systems, energy-saving measures and features needed for comfortable and efficient operation. With the current focus on environment, most of the construction machinery is geared to perform with less noise, less vibration and low emissions.
The sheer complexity and sophistication of mining equipment today is astounding when comparing the state of equipment even 50 years ago. The technology used in most mining operations today is increasing the efficiency and productivity of the world's largest mines, so that supply of minerals and metals can meet demand. With the incredibly high performance of machines on offer comes the responsibility of the company to maintain the equipment in every way possible. Just as in any other high performance piece of equipment, it is only optimized when all the parts are working at their maximum potential. Allowing worn out parts on these pieces of machinery and expecting the same performance quality is equivalent to putting worn out tires on a high performance race car and expecting it to win races. Not replacing the needed mining wear parts drains money from a mining operation due to lack of efficiency, and also puts the workers at risk of machine failure. This is a risk that no employer should be willing to take, considering the human and financial costs associated with equipment malfunction.
Wheel loaders come with various options which are designed for operational ease. The levers and pedals can be operated with minimum force to achieve better control. Visibility is the important factor for wheel loaders for comfortable operations. In construction sites, the hydraulic pump motor in the wheel loaders provides easy mobility.
Articulated dump trucks are mostly used in construction sites located in hilly terrains. Because of the sloping terrain, the operator in the cabin is provided with more visibility of the surrounding area. The truck comes with diagnostic display controls and warnings for malfunctions to provide safety.
Rubber crawler carriers are good for uneven and muddy construction locations. Even when carrying heavy loads, on soft ground conditions, these carriers should run smoothly to prevent accidents. At the same time when used on a paved road, they should not damage the surface of the road. Another factor to be noted is that the rubber crawler carrier should be able to pull out of hindrances and ditches in the construction site.

The role cone crusher plays in construction industry
Due to deficient operating rate, the engineering machinery market (cone crusher) didn’t behave well in the second quarter whose sales dropped greatly compared with the first quarter. Seen from the year-on-year statistics, the continuous deterioration of the year-on-year decline has basically stopped. However, what should be noticed is that the first quarter in 2011 is the demand summit in recent three years. The chain decline speed of the second quarter in the same year has surpassed the seasonal pattern of the former years. Therefore, though the year-on-year requirement is basically lowered, the decline situation of the chain still reflects its real demanding weak state. Meanwhile, it is also should pay attention to that the homemade brand appears superior to the foreign b rand in spite of the fact that the overall market is poor.
The regeneration brick of construction waste is formed through sorting, crushing, sieving into coarse and fine aggregates, and then based on a certain percentage, mixing the coarse aggregate, fine aggregate and cement, making by the brick molding machine. After a period of maintenance, the regeneration brick of construction waste, which complies with the target level of product quality, is produced. The regeneration brick making from construction waste has obvious features, such as material saving, water saving, coal saving and so on.
Generally speaking, the building stones are the most important part in construction industry. Without the building stones, the construction can not exist any longer. However, the mountain stones are huge and hard. It is impossible to make the mountain stones into building stones with hand crushing. Therefore, the rock crusher, aiming at crushing the stone, becomes the right arm for construction industry. The rock crusher has many types. When crushing the relatively soft stone, the demand for the rock crusher is not high. But when crushing the hard stone, if the quality of rock crusher is not good, the final result only will be that the rock crusher is damaged and can not work any longer. Thus, the customers will suffer great losses.
After many years' development of the domestic mining machinery industry, all aspects are perfected and the production technology is also constantly being updated. In particular, the crusher and the mill industry is developing rapidly this year. In the rapid development, the appearance and some design concepts of the equipment in China are almost the same with the foreign brand products. However, we will find a lot of flaws from detail through careful study. There is still a big gap between domestic products and the foreign products. These are mainly the technical reason and the reason of concept. Henan Hongxing Mining Machinery Co., Ltd. thinks that the the domestic mining machinery must give top priority to quality. As a crusher manufacturer, Henan Hongxing Mining Machinery sticks to attitude first, process design first, details first to go all out for quality management.
Usage of jaw crusher in infrastructure construction
Jaw Crusher, which mainly used for the roughly crush, is a first crushing application in the stone broken line.There are many models of jaw crushers in the world. However, the jaw crushers can be divided into a single elbow crusher and elbows crusher from the structure of the jaw crusher. Nearly half a century, many factories have made the modern technology, such as a variety of senior roller bearings, hydraulic technology, non-blocking type of crushing chamber and high-strength materials apply to the structural improvements of the jaw crusher, which has obtained satisfactory process.
The elbows crusher is also known as simple pendulum jaw crusher or Blake crusher. The work is strong since the horizontal stroke of the most distant suspension point is large. In this way, the hard ore can be crushed. The vertical stroke of the mobile jaw is small and the wear of the liner of the elbows crusher is lighter than that of single elbow crusher. However, the upper stroke of the mobile jaw of the elbows crusher is small which affects its efficiency.
The rural infrastructure construction, Major infrastructure construction in road, railway, airport, Earthquake disaster area ’ s reconstruction are the focus of the State investment, and the fast speed of the construction can promote the steady economic growth, so, the construction bring in the new opportunity in the application of the crusher. The jaw crusher is used to crush materials with a compression strength of less than 320 M Pa. It is often used as primary or secondary crushing equipment (the secondary crushing equipment often using cone crusher and impact crusher). The jaw crusher is widely used in industries such as mining, metallurgy, chemicals, building materials, water conservation, and for highway and railway related infrastructure projects.
Working principles of complex pendulum jaw crusher:
The upper end of movable jaw hangs in the eccentric shaft directly. Connecting rod of crank-link mechanism drives directly by eccentric shaft, the lower end of movable jaw connect with the toggle plate and support to the back wall of the rack. When eccentric rotates, the motion curve of every point in movable jaw is circumference of the pendant point (radius equals to eccentricity) gradually down to become ellipse, the lower, the more slanting of ellipse, till the bottom becomes arc with the track of toggle plate junction point. As the motion curve of points in the movable jaw is complex, the machine is called as complex pendulum jaw crusher.
Crushers used in water conservancy construction
The water conservancy construction plays an important role in protecting the development of agriculture. It is expected that the water conservancy investment will grow double in the future under the pressure of inflationary. The investment scale had reached 400billion to 500 billion Yuan in 2011, the investment policies will sustain over the long time, which is expected to reach trillion Yuan within ten years. Such a huge investment is bound to cause a fiery situation of water conservancy construction. Then, the market will need a large amount of cone crusher, sand maker and other series of sand production equipments. The cone crusher and other equipment manufactures should make preparations as soon as possible to fill the vacancy of market.
1, surfacing: although there are kinds of surfacing electrode, its price is very high. If you choose inappropriate electrode or use improper measure, it will increase the cost and the difficulty of processing.
2, casement: it need to calculate the strength and determine the minimum allowable diameter. Because the rotor system need overall disassembly and be processed by large-scale lathe.
3, thermal spraying: this method needs high conditions, for the spindle is not easy to disassemble, the huge rotor is difficult to achieve the desired preheat temperature. Before turning, please strick the coating by using steel bar and evaluate the bounding strength of coating. The cost of spraying raw materials and turning processing is higher.
The moister content of the materials also affects the productivity of the compound crusher. When the materials contain large amount of water, they are easy to form the adhesion phenomenon in the crusher, causing obstruction in the process of feeding and nesting and reducing the crushing capacity. As for the materials with high moister content, the workers could take certain measures to control the water content. For example, they can use the dryer or sunshine to reduce the moister content of the material, and then carry crushing operations. Therefore it is recommended that mining machinery industry should adapt to international market demand changes, and adjust and optimize the structure of exported products. Besides, develop the potential market, emphasis on the impact of European sovereign debt crisis. Thus, we can make improvement both in product innovation and products exporting.
Hongxong provides green crushers for construction
The rapid construction of high-speed railway can not do without the use of aggregate. Because its higher standards on the level and shape of concrete sand and gravel aggregate, especially for the content of needle and slice shaped basalt, the simple cone crusher orimpact crusher processing can not meet the requirements. Green technology refers to the technical system that can reduce pollution and consumption. Green technology is dynamical system consist of related knowledge, ability and material means. This means that the knowledge and ability of environment protection, ecological reconstruction and the material means are all the essential factors of green technology, only these three factors are combined and interacted, that they can constitute the practical green technology. Environment protection and ecological knowledge are the indispensability factors of green technology. And its innovation is the application of environment protection and ecological knowledge.
The clinker roll crusher is a primary component to drive the grate motor, it is mainly composed of cylinder body, roller, speed measuring device and the transmission. The roller crusher has several rollers, each is installed with a roller shell. And it is easy to extract each roller to change the roller shell. Furthermore, every roller is drived by a helical gear motors with a planetary reducer.
Clinkers fall from the grate bed onto the roll crusher, the fine particles fall into the discharge chute between the rollers, while the larger blocks are crushed by the roller. A roll crusher has several rollers, the adjacent two rotate against with each other and the relative rotating couple forms a crushing unit, several crushing unite like this complete the crushing work. The rotation direction of the roller closest to the discharge port is clockwise while the farthest one is anticlockwise, those two rollers’ rotation is irreversible.
