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.

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.

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.
