Green Roll Crusher Adapt to Environmental Idea

After we analyze its working principle, we will find that it is just suitable for cement production technology. This material in powder form can be changed from plasticity paste to hard stone-like body and can become a total cemented granular material through physical and chemical processes after being mixed with water. So it is a good mineral binder. It can be not only hardened in the air, but also better hardened in the water in which it will maintain and develop strength. So it is kind of cementitious material which will be of stronger hardness in water. Ball mill is used for cement grinding. In the concrete mining, you need to choose suitable grinding mill and impact crusher.
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. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like china dryer, Henan Hongxing is always doing the best in products and service.circular vibrating screen: http://www.china-hxjq.com/p21.html
The drive current of each roller is set with a limit, when encountering extreme hard or large materials, the roller will reverse automatically when the current overloads to protect the roller shell from getting damaged. The reverse operation is as follows:
1. Under normal conditions, the roller stops with its paired roller on the outside, performing the following actions in the middle of them.
2. The action roller stops for t1 then reverses for t2 to get stopped.
3. For another t1, this pair of rollers re-starts and rotates in normal working status.
4. It will send out an alarming signal when the times of the reverse operation surpass n in t3.
The above procedures are controlled automatically via the program. When it alarms, the maintenance staff should find the problems through the manhole and the observation hole. Then the roll crusher can be re-started after the troubleshooting is completed.
If the feeding materials are not uniformly distributed on the full length of the roller, the roll surface will be quickly worn and each point is worn in different level. For this reason, annular groove will be formed so that the normal crushing work is damaged and the grain sizes of crushed products are not uniform. Therefore, apart from the roller crusher that is used for coarse crushing, the medium roller crusher and fine roller crusher are equipped with feeding machine to ensure the feeding continuous and homogeneous. What's more, the length of feeding machine is same with the roll length so that the feeding materials can be uniformly distributed along the direction of roller length.

Building Waste can be Transformed into Available Resource

With the accelerated pace of construction waste in a lot of cities, the construction waste has increased significantly as the product for urban development and the replacement for the buildings. Recycling the construction waste is helpful for energy and resources saving to protect the environment. In addition, recycling the construction waste can solve the contradiction between the shortage of the city garbage piling venue and the encroachment of farmland, which can also avoid the piling up of the garbage and bury the pollution of groundwater resources.
Recycled construction waste mainly applied in two areas: first, road construction. Recycled construction waste aggregate can be used in road construction field instead of natural gravel as road stabilization layer (road sub-base and road grassroots); recycled plain cement concrete aggregate can be also used for the following layer and surface of the asphalt pavement layer. In Germany, construction waste is widely used in road construction. However, whether it is used for road stabilization layer (road sub-base and road base layer) or used for the following layer and surface layer of the asphalt pavement, the construction side has strict regulatory requirements of the particle size and sieving aggregate shape.
Another application field is engineering and construction. Construction waste recycled aggregate can produce hundreds of engineering construction materials for walls, floors, roads, landscape construction and architectural decoration, highway, water conservancy, etc.
Construction waste disposal equipment has two forms. One is all terrain mobile crusher station; the other is semi-mobile crushing station. Compared with domestic manufacturers, these two forms apparatus have five-point advantage.

Third， Hongxing construction waste recycling equipment can handle the litter and soil high containing amount of 'hybrid' construction waste. We can give different solutions for customers according to specific type of visual construction waste.
Fourth, magnetic separation way of steel and iron piece in handling construction waste is different. Hongxing magnetic separation is adjustable electromagnetic drag type, is dedicated construction waste disposal device. Compared with the current magnetic separation device, the design concepts and application are different;
Assumptions deal with the 40 Articles of construction waste, will require about 20,000 vehicles to transport finished, the transportation costs of about 12 million yuan, the transit time of about one and a half years. Handling of the mobile crusher plant is only 500 million on-site treatment costs than construction waste Sinotrans savings of $ 700 million, nearly 60 percent of the cost savings. Portable crusher plant to day 2000 party construction waste, construction waste of 400,000, goes well, six months on all processed than construction waste Sinotrans save a year’s time. Each mobile brick making machine coupled with the digestion of 200 tons of construction waste, all construction waste in place you can “change waste into treasure.

Focusing on Development Points of Mining Machinery

As the gentlemans gentleman factory and the manufacturing base, the ontogeny of Asian manufacturing effort has been given colossal attention. On April 2, Boao Asian Forum and Liaowang hebdomadally jointly held Boao manufacturing constancy Round table conference and the tycoons in the manufacturing industry from The United States of America, Germany, France, Japan, South Korea and mainland mainland China made great proposals and contributions to the development direction of this industry of China and Asia. At present, because of the alive problems such as the contribution rate of technological be on and innovation to the economic growth is not very high, the transmutation and upgrading of Asian manufacturing is extremely urgent. On this round table conference, the leadership of the industry in all countries deeply discussed the strategic topics that approximately people are concerned with such as the reconfiguration of global industrial chain in the post crisis age, transformation and upgrading of the manufacturing industry and new technology evolution and global economy resailing. roughly the world, the sovereign debt crisis by the impact of the euro zone economic lookout is bleak, become a few years threaten the world at present and in the future the economic convalescence and increase of the main uncertain factors.
At present, the development of China's mining machinery industry also exists problems, and troubled by factors such as the overall strength and technological base is relatively weak, product quality and technical are low, etc. Therefore, speeding up the integration and producing high-end independent innovative products is the best way to adapt to the current economic development pattern for mining machinery industry; it is also the center for the continuous development of China's mining machinery.

Coal Crusher plays Pivotal role in Crushing Coal Mining

The research department pointed out that the total consumption of the coal industry in China continues to grow, it will show the two major effects of the resources integration and capital integration in the '12th Five-Year period and enter the adjustment period of high speed development. The transformation and upgrading of the coal industry is bound to accelerate the degree of mechanization of the coal processing equipment and create the newborn for crusher industries which relying on its development.
Because the service life of small jaw crusher has only three to five years, the crusher needing replacing every year in China takes up 20% of the total amount. Even though there are many crushers operating in poor condition, large-scale renewal and replacement is no big deal. In addition, the impact crusher applied in the ore beneficiation and construction is short in variety and few in specification affects the development of infrastructure development such as road and cement construction. The renewal and replacement of crusher is inevitable, which is also one of the conditions improving China economic development. To sum up, it is emergent to improve the workmanship and service life of crusher.
With the continuous development of the world economy, the consumption of coal resources grows in the dramatic speed; coal industry faces heavy environmental pressure. In response to this situation, Hongxing machinery bases on years of production experience and market practice survey, constantly improves the equipment. Efficient jaw crusher,belt conveyor and other equipment could crush gangue into various types of construction aggregate, reducing the emission of pollutants and achieving reasonable recycling of waste resources.

After years of rapid development, the coal industry will slow down the pace to enter the adjustment period. At the same time, it will also bring respite to the crusher industry. Crusher enterprises should strengthen the quality system management, enhance the technical content and improve the future development strategy to ensure the prance of coal industry in the future.
Crusher industry is an important pillar industry of the national economy; the emergence and development of the crusher industry greatly improve the ability of people to transform nature. The secret that the crusher industry has been so long enduring lies in the constant technological innovation. As the important branch of the basic industries, it”s particularly important for China”s basic industries to take independent innovation. Looking into the future, Hongxing will continue to adhere to the technical innovation as the development philosophy and strive for making more and greater contributions to the development of China”s crusher industry.

Approaches of Crusher Development in Severe Market

With the development of mining crusher, to a certain extent, it improves the overall mining process, and the crusher is the core equipment in large mining processing. In accordance with the ore feed size and the material grain size, the crusher is used for coarse crushing, medium crushing and fine crushing. The development of the crusher on basis of applications constantly improves the product performance, to a greater extent, meeting the demand.
In the context of the economic downturn, what crusher manufacturers can do is on the one hand to strengthen cooperation with various countries, as well as the domestic region, on the other hand, we must cultivate internal strength to increase our own hardware and software innovations in technology and upgrading of the equipment, as well as good corporate culture and the training of employees, improving the overall quality of the leadership.
Software factors:
1, treat science and technology as the guide, increasing the proportion of scientific and technological content in the enterprise, really shifted to technology-based track, avoid previously catching with the market.
2, improve staff training and leadership quality. Only continue to improve the operation of the staff level can we produce higher-quality equipment and win in the fierce competition by quality.
Hardware factors:
1, weed out of the backward products and develop the strongest demand equipment on the market. Of course, this was done by a software technology. In different historical conditions, the demand for equipment are certainly different, we should keep up with the pace of the times.
2, upgrade the product and readjust industrial structure. For example, Hongxing machine, which is a professional kiln machine manufacture, timely combines with the analysis of customer's consideration of the proposals and peer their own research and development of the third generation sand maker.

The crusher equipment is one of the mine’s main production equipment, which covers metallurgy, nonferrous metals, building materials, chemical and other industries. Crusher is characterized by large crushing ratio, high output, low energy consumption, uniform particle size, which is widely available. In recent years, many domestic and foreign manufacturers improve and perfect the crusher equipment from the product structure, and have launched a number of efficient, reliable, and energy-saving new product. By comparison, domestic crusher is relatively backward due to the impact of the automation level of development. Over the last decade, some products abroad are equipped with appropriate instrumentation and automatic control devices, which has played a certain role in equipment protection, stability operations, production increase. China in recent years began to carried out on some new crusher automation research, and configure the detection and control instrument: concern, however, mines in China own crushers to the majority of the old equipment in the sixties and seventies, and has been playing an important role in production. Automated transformation of these old equipment achieves automatic control and has broad prospects in the mining machinery industry. Because almost the whole operation and control of domestic crushers are entirely by manual. Impact crusher manufacturer year-round produce various types of impact crusher, welcome new and old customers to buy.

Hongxing Takes the Road of Low Consumption

Recently, the National Energy Administration issued a note about weeding out backward production, which pointed out that our country will continue to week out backward production in coal, reduce the number of small coal, expand and ensure the large-scale coal enterprises occupies dominant position in the development of coal industry. The reformation ensures coal production during eliminating, therefore, the use of modern coal mining equipment is admitted of no delay.
Energy saving and environment protection is familiar to general public. However, it is not only a performance of life attitude, but aslo a kind of determination of fashionable concept.

Solving Methods of Usual Malfunction of Hammer Crusher

Today we will introduce the performance and structure of hammer crusher. Firstly comes the crusher briefly, thus, we can better understand the theme. Crushers mainly can be divided into jaw crusher, impact crusher, hammer crusher, roll crusher, combination crusher etc. . Here basically, we’ll make the hammer crusher introduction, and other types involved will be introduced in the following-up articles. Attention, please.
1. The bearing runs hot.
Reasons: The lubricating grease is insufficient; there are two much lubricating grease; the lubricating grease goes bad; the bearing is damaged.
Elimination ways: Add proper amount of lubricating grease; the lubrication grease inside the bearing should be half of its volume; clean the bearing; change new lubricating grease; change the bearing.
2. The granularity discharged is too big.
Reasons: The abrasion of the hammer is serious; the grate bar breaks.
Elimination ways: Change new hammer; change the grate bar.
3. The output decreases.
Reasons: The gap of the grate bar is blocked; the materials are not fed in an even manner.
Elimination ways: Stop the machine and clean the tamper inside the gap of the grate bar; adjust the material feeding mechanism.
4. There is knock on the elastic coupling.
Reasons: The pin roll is loose; the elastic ring is abraded.
Elimination ways: Stop the machine and tighten the pin roll nut; change new elastic ring.
5. There is knock inside the machine. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like stone crusher, Henan Hongxing is always doing the best in products and service.circular vibrating screen: http://www.china-hxjq.com/p21.html
Reasons: some materials that cannot be crushed go inside the machine; the fasten part of the lining board is loose and the hammer knock on the lining board; the hammer of other spare part breaks.
Elimination ways: Stop the machine and clean the crushing chamber; examine the tightness of the lining board and the gap between the hammer and the grate bar; change the broken spare parts.
6. The hammer crusher vibrates.
Reasons: The static balance of the rotor does not reach the requirement when changing the hammer or due to the abrasion of the cone head; the hammer breaks and the rotor loses its balance, the pin roll twists and breaks; the triangle plate or the round plate breaks; the foundation bolt is loose.
The main working part of this series of stone breaker is rotors with hammer. The rotors consist of main shaft, disk, pin shaft and hammers. The motor drives the rotors to rotate quickly in the crushing cavity. Raw materials enter the stone crusher through the feed opening and are stricken, impacted, cut and ground by the high-speed hammer to small size. There is a screening plate under the rotor, so that materials with size smaller than the screen mesh will be screened out and others are left to be further hammered and ground until reach the standard size. The size of the final product can be adjusted by changing the screening plate. The gap between the rotors and the screening plate can also be adjusted according to different requirement.
