Discussion of Increasingly Crushing Technology
China’s economic development continue to rise ,the domestic also pay more and more attention to the construction of infrastructure, in high speed railway, highway, water conservancy Bridges, urban and rural areas reconstruction project development quick, which also promotes the rapid development of the sand making machine industry, and occupies a very important position in the mining industry developing . Sand making equipment in cement plant, glass, refractory materials, metallurgical and other industries in the development of get reasonable application, according to the infrastructure construction, machinery industry, gravel industry to promote the cycle of development situation, our country’s sand machinery technology also constantly increased, at present our country mechanism sand equipment to achieve a high standard, can meet the demand of contemporary construction standard and demand.
With the development of mining machinery industry, the demands for crusher industry gradually increase. Crusher industry in China is quickly popular under the strong pull from home and abroad. After the technological updating of crusher equipment, its application scope is increasingly extensive. When being used in ore beneficiation industry, crusher equipment is also widely used in cement industry and coal gangue, showing its significant role.
A lot of waste produced in the coal industry ,such as coal gangue, it will have bad influence on the environment if piled up with large quantity on land. Moreover, it also contains a certain amount of combustibles, and spontaneous combustion will be caused under the proper conditions, which will increase the emissions of sulfur dioxide, nitrogen oxides, carbon oxides and soot and other harmful gases to pollute the atmosphere environment, affecting the health of residents in the mining area.

Screen Equipment is Applied in Concrete Aggregate
The high frequency ore screen separates materials according to above two points. In the grinding circuit, the high frequency ore screen controls the grinding equipment to do the classification. In addition, the screening material can meet the fineness requirement, which can reduce the energy consumption, improve the mill production, and increase the benefits. What’s more, installing the high frequency ore screen in the grinding circuit can screen out the coarse concentrate and send them back to the grinding mill to do regrinding, and select the screening material to improve the grade of concentrate.
Cement concrete comes into being since an earlier time, and it plays an important positive role for construction and building industry. However, with time goes, there are generating more and more concrete waste, which caused serious environmental problems. For example, we say it 2 billion m3 of concrete storage in China at present, which needs 0.8 billion tons cement and natural sand consumption is at least 3.6 billion tons. Statistics shows that we product 1 ton cement will use 0.95~0.98 ton clime, and 1 ton aggregates will discharge about 1 ton CO2. At the same time, it will let out a large amount of harzadous gas and dust. In aggregates proportion, natural sand takes much account. While as endless mining for decades, some natural resource can't meet large demand. What' more, natural limestone with industrial value just is able to keep supplying for 30 or 40 years. Over-exploitation has lead to earth losing and environment worsen. It has a bad effect to natural resources sustainable development. According to incomplete statistics, China generates annual construction waste 0.1 billion tons at present speed. If these construction wastes could be used in a proper way, it makes sense greatly.

Recycled concrete aggregate refers to that we make use of old concrete waste to produce artificial sand. The production process includes selection, crushing and screening, and artificial sand has a certain physical performance and certain particle size. In the process, vibrating screen will remove foreign materials, and then the waste past through crushing by jaw crusher. Finally, the particle size, roughness, density and water taking property are decided by customers' demands. Therefore, the vibrating screen is also made object to users' demands. It may be no easy to determine number of screens since the different grain size. As there are different measuring standard from country to country, the measure unit 'mesh' sometimes is difficult to come into agreement.
The mining industry is one of the biggest users of vibrating screen technology. Taking ore and minerals from the ground results in many impurities, so these organizations load goods into a screen until dirt and non-valuable rocks are shaken from material such as coal, iron and ore. Screens also are utilized in manufacturing, especially when metal items, such as ionised bolts and screws that need to be submerged in a bath, need to be dried. Here, full containers of liquid and metal can be poured through the screen and separated with the vibrations to ensure that they dry completely. Disparate industries such as archaeology, metallurgy and construction also utilize vibrating screen technology to get their jobs done.
Crushing Machines Efficiently Solves Steel Slag
With the continued strengthening of the engineering construction, the broken machinery industry showed a good momentum of development under the situation where the machinery industry as a whole is in the rising state. With the help of the great support in the high-end equipment and other emerging crusher machinery, the crusher machinery, as a focus area, will continue to show the rapid growth situation. According to the analysis, the main direction of future growth of the broken machinery (impact crushing machine, jaw breaker) is the product upgrade to occupy the market share as well as the new growth point created by the innovation and R & D of the new product.
According to statistics of 300 companies from mining machinery branch in China, mining machinery industry sales in the 1-3 quarter of this year has rose by 16.03% compared with the same period last year. But compared with last year growth rate and the year before growth rate 30%, the growth rate of 1-3 quarter slowdown a lot. Mining machinery companies should depend on their own actual situation, make certain adjustments to the product series, take a certain amount of energy-saving measures, make some progress of large, environmental protection, and energy saving equipment technology. They will also invest funds to accelerate the upgrading of products. In an effort to do a good job in product quality, at the same time, they also increased after sales service requirements, to earn a good reputation to favor the consent of customers all over the world.

In this case, when coincided with periods of high attention of international environmental topics, such as climate change and energy, environmental protection, low carbon economy become international hot discuss issues on the current. One industry source said: 'Energy-saving, environment-friendly products are the medicine of the future risks.' It is understood that the company independent researched and developed crawler-type mobile crushing plant, PFW deep cavity of inversed impact crusher, Hongxing CS cone crusher, LM vertical grinding mill, MTW European trapezium grinding mill machine. And now these products have already been booked out 40 units, whose market prospect is very good. While, whether mining machinery enterprises can be freed from the crisis as soon as possible is still a mystery. It launched a heated debate as for what measures should take next of mining machinery. Scrap steel processing industry development trends abroad is scrap crushing and sorting process which be taken as a leader. And this process uses environmental, mechanical and electrical integration technology to research and develop new types of scrap iron and steel comprehensive treatment methods. That will become a new industry and new economic growth points.
Stone crushing production lines developed by our business are efficiently utilized in limestone, basalt, granite and pebble; the completed product or service reaches the normal of GB14685-2001, which happens to be the perfect aggregate for highway, railway, drinking water conservancy and concrete mixing station.
Other Industries Drives Development of Crushers
Now, influenced by many new types of crushing equipment, the sales of the industrial impact crusher suffer significant influence. The introduction of vertical shaft impact crusher completely replaces the original sand making methods since it highly-efficiently uses the crushing principle of stone impacting stone and iron impacting iron, and significantly improves the production efficiency. The fineness range of the sand produced is ensured so that it becomes the most competitive sand making machine. For this reason, the impact crusher does not have advantages in the application of sand making, and it can only be used in second crushing at most.
At present, it appears a phenomenon of surplus capacity, slowdown growth and fierce competition in the market that results in a slight decline of the machinery industrial sales. Plus few propagandistic activities in the first half year in the enterprises, the machinery industry is confronting an off season. As a most significant part of the marketing, the exhibition has become an optimal opportunity for the enterprises to grasp to raise their popularity. It is revealed by the senior people that most exhibitions are going to be presented at the end of the year, a tide of exhibition will be started and thus crushing equipments are about to get on the stage.
Under a high-speed economic developing circumstance, the number of the machinery exhibition is soaring, so is the number of the exhibitors, the exhibition close to the second half year is about to get started gradually. The exhibition has not only become an effective propaganda tool, but also turns into a commercial war battlefield without smoke. On the one hand, enterprises obtain market message via prompt propaganda and communication with consumers and rivals directly. From the above things, they get to know about their proper deficiency and then to promote the products’ quality as well as accelerate the R&D level etc. On the other hand, through this best opportunity, the contact among new buyers all around the world is able to be fulfilled. In addition, they vie for customers and industrial talents to enlarge their own market share.

Recently, 2012 China Mining Conference on Science and Technology has been held in Jinan, Shandong. Ministry of Land and Resources, numerous mining enterprises at home and abroad, colleges and universities and institutes which account for about more than 900 representatives attended the meeting. This is both the national top mining technology summit forum and an exhibit platform for the mining equipments, but an important stage for the crushing enterprises to start their brand. Except for discussing and studying issues like the development of the domestic and overseas mining resources, supply pattern, the adoption of beneficiation technology and device and the problem of saving energy and environmental protection, various sizes of cone crusher, jaw crusher, mobile crushing station and impact crusher etc. have all been presented on the show, which have attracted a lot of spectators.
Consequently, the function of the impact crusher is gradually positioned as equipment for producing building materials and second crushing. However, the impact crusher also suffers the impact of fine jaw crusher and cone crusher. The fine jaw crusher does not have great impact on this machine, but the impact of cone crusher can never neglected. Cone crusher was only used mining crusher, but now it also has wide application in sand and stone crushing. The hydraulic cone crusher is stable in operation and high in production capacity, and it has hydraulic protection and cabin cleaning device, so that it is really a powerful opponent of impact crusher.

Six Steps to Extend Use Time of Vibrating Screen
Vibrating Screen should be run unloaded, we shouldnt feed it until the Vibrating Screen runs smoothly. It cannot be stop until there is no material on the surface of Vibrating Screen.Henan Hxjq machinery co., ltd is a famous manufacture of crushing and screening equipment in china, which is specialize in producing medium-sized and large scale Crusher, Sand Making Machine, Circular Vibrating Screen, Mill, Mobile Crushing Station, etc.
Taking the large scale vibrating screen as the investigative object, researchers utilizes advanced means of vibration testing and dynamics analysis theory, and applies the dynamic design method combining theory modeling with experiment modeling to the dynamic design process of large scale of vibrating machines. Using analysis technology of finite element, the mode parameters and the mode shape of the vibrating screen’s prototype are obtained primarily. Then according to these parameters, design structures are modified elementarily to be used as the design basis of the physics experiment model and the main reference about how to dispose the experiment measuring point.
The correct use and reasonable maintenance of vibrating screen will help to extend the service life of the vibrating screen. Therefore, in addition to correct operation that is in strict accordance with the instructions, the following details also should be paid attention.
1. the operator and the users should learn more about the basic structure and working principle of the vibrating screen, conduct frequent inspections and regular checks, gain experience and collect operating datas and record them.
2. before dismantlin the transportation fixed plate, it is not allowed to open the vibration motor. If the transported fixed plate are not dismantled before the startingup of the machine, it may result in damage to the equipment and vibration motor, even the personal injury.
3. every time the operators start the vibrating screen, they should check the screen to make sure that the screen is pressed and smooth and the beam ring screws are properly tightened. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like flotation separator, Henan Hongxing is always doing the best in products and service.bucket mixer: http://www.hxjqchina.com/product-list_39.html
4. in addition, the operator should carry out the necessary checks, focus on the lubrication of each lubrication point and whether each connection piece is loose and the moving parts are out of nimbleness and ensure the necessary gap between all moving parts and the fixe parts. And after the vibrating screen operates for eight hours, the operator should re-tighten all the fasteners of the equipment.
5. when the vibrating screen is started, it should be in operation without load. After the vibrating screen is in smooth operation, the operator can gradually begin to feeding. Before stopping the machine, the operator should stop feeding. The machine can not be stopped until the materials in the machine are discharged out completely.
6. if there are unusual circumstances when the vibrating screen is in running, there is the need to repair or conduct routine maintenance.
Testing technology of vibration is used to found the experimental model with multiple testing points to obtain the mode parameters and the mode shape of the structure. Based on sufficient analysis of testing data, vibrating displacement field and any other dynamic characteristics are obtained .So the stress field is obtained indirectly. Modifying the model of theoretic analysis and the structural dynamics can be on the basis of these dynamic parameters In this way, the shortage of the traditional static design method can be settled well. In this investigated subject, on the basis of the vibrating screen’s working principle, the kinematics of the materiel on the screen surface and the dynamics of the vibrating screen are analyzed in detail. Consequently technical and structural parameters of the prototype of the vibrating screen can be confirmed. Based on the destroying mechanism of the vibrating screen, the principle of choosing materials for the structural pieces of the vibrating screen and which kind of metal materials is apt to the structure of the vibrating screen are determined.
Experts Generally Expound Beneficiation Process
Iron ore beneficiation process due to the influence of the ore itself properties and production processing size requirements, secondary fine grinding equipment not cone crusher belong to, iron ore cone machine can provide more small product size, but also in quality of product suitable for a complete set of production line to cooperate.
Before the ore beneficiation process, the beginning stage of the test work is the most difficult. The research on the composition characteristics of the ore materials can help experimenters faster and more safely choose the beneficiation method and process. At the start of the study in the laboratory stage, it is best to adopt the effective methods in industrial production. When the sorting indicators are not satisfying, it is worth the potential of new technology to develop applications.
The first step for processing the ore is the crushing process, grinding process and the related sieving and grading operations. For most of the ore, the purpose for crushing and grinding is to achieve the dissociation of the mineral particles monomer. If the ore needs to be finely ground, any conventional method or process can be used to crush the samples into the feeding size of the laboratory grinding machine. Conversely, if the mineral ore gathers sufficient amount of particles with coarse particle size, the gravity concentration is very necessary. The crushing and grinding processes should adapt to the sorting process. In addition, the over crushing phenomenon should be avoided.
If the useful mineral particles are too coarse and there is great density difference compared with the gangue, you should firstly consider the gravity concentration. The most commonly used gravity concentration equipment is the heavy media beneficiation machine, jigger and the shaker. Only some sand deposits may use the long chute centrifugal concentrator, the cross-flow belt chute and other fine gravity concentration equipments. The entire process is based on the gravity concentration. In addition, in order to reduce the influence of the particle size and choose different devices according to the different granularity, the grading operation is very necessary before the gravity concentration. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like mobile crushing station, Henan Hongxing is always doing the best in products and service.iron ore concentration plant: http://www.crusher-machine.com/n137.html
Flotation can be seen as a universal principle. Almost all industrial minerals can be recovered by flotation. The separation efficiency for the symbiotic mineral is also not comparable. For the ores which are difficult to depend on the gravity concentration, the flotation test should be arranged. The scope of application of magnetic separation is very easy to make a clear judgment according to the magnetism of the minerals and the magnetic tape granularity. For example, the wet weak magnetic field magnetic separation method is mainly used for the recovery of magnetite and the pyrrhotite.
To sum up, the technology indicators and the level of economic indicators of the dressing plant are depending on the crushing process and grinding process. So each beneficiation workers must take seriously the grinding process and grinding equipment to minimize the cost of crushing and grinding.
