Low-carbon technology

Posted: March 30, 2016 in nonmetallic ore

‘Two sessions’ has ended more than two months, the ‘One proposal’ concern, we attracted everyone’s attention, as early as we know it ‘low carbon’ At the meeting, leaders became a hot topic Marble Stone Processing Plant. ‘Recommendations on promoting economic and social development of China’s low-carbon’ by the central government, has been highly recognized National Development and Reform Commission, the instantaneous carbon entered a new era.In recent years, the frequent occurrence of natural disasters, unstable climate, warning people of China is already one of the most serious impacts of climate change affected countries in the world, climate change has become one of the biggest factors in China’s economic development. Jiu San Society Central Committee put forward proposals outset that ‘the development of low-carbon economy to reduce carbon dioxide emissions will be China’s future long-term and arduous task.’ In recent years we have always stressed, ‘green’, ‘green’, in essence, is to speak carbon.

Low-carbon, not so much a new topic, as it is a topic of our concern for a long time; low-carbon, not so much a problem facing our country, rather, this is a global problem; low-carbon, not so much it is a specific technical problem, rather, it is a way of relating to the development of ‘grand narrative’ problem. Politicians from all countries to the public, such as on global warming, the melting of icebergs, Germany unstable temperatures, the seasons are not distinct, earthquakes, greenhouse gas emissions, rising sea levels, etc., are familiar. This is not only in respect of both a ‘people’s livelihood’, and relates to ‘national planning’ problem.Government Work Report ‘two sessions’ proposed that strive to conserve energy and reduce emissions. During its consideration of the NPC members to discuss the government work report that the reason said to be ‘tough fight’ and ‘enduring support,’ explained energy conservation, low-carbon economy great difficulty, tasks prosperity, must unremittingly Attapulgite Powder Vertical Mill.

But ‘the development of a low-carbon economy must create a new cycle of economic evaluation index system, the only way to change local government blind pursuit of GDP growth and the incremental costs of environmental neglect to pay for.’ Throughout the development of low-carbon economy is there are many deficiencies, the most important part is, with the development of infrastructure, construction waste continue to rise each year in construction waste above the high cost, but it did not make good use of resources, for us such a it is the shortage of human resources in developing countries is undoubtedly a more serious loss.According to reports of about three hundred million tons of construction waste generated each year, a huge amount of construction waste take up a lot of land, heavily polluted environment.

crusher tooth Detailed stress analysis of specific

crushing teeth mesh static method is an effective method of stress analysis fractionation crusher teeth at maximum load may be subject to various forms of analysis. In breaking tooth stress analysis, used physical parameters.

crushing teeth physical parameters elastic modulus / (Nmm-2) Poisson’s ratio mass density / (kgm-3) yield strength /(MPam-2)2130000.286787012152 broken tooth load modeling at different stages in the process of crushing, crushing teeth the surface of each play a different role. In the material biting stage, mainly the first surface to the top edge of broken teeth and broken teeth adjacent to the top surface of the contact material, this time local contact materials and broken teeth top surface in contact with the top surface of the front edge of the broken tooth Manufacturers Of Sand Crushers. After the material bite, broken teeth adjacent top, side, front and back surfaces of the blade is formed by the space, which has a chance to surface material under pressure generated by the reaction, this time with the whole surface of the contact material, or only with these local contact surfaces. Thus, when respectively top, front, back and side load simulation, stress distribution study different facets loading stress distribution, the study suffered broken teeth in all directions at maximum load. Class 8 simulation loading.

finite element analysis results broken tooth stress distribution is top loading, from which can be seen, the maximum stress appears in front of the center of the tooth root, the maximum stress value of 325MPa, below the material allowable stress values. Addendum is broken blade loading stress distribution, the maximum stress appears on the broken edge and a maximum of 113MPa. Visible at the same intensity load, when the use of broken blades were broken, can reduce the overall maximum stress broken teeth. Compare and top edge of the crushing stress that: two broken under stress loading mode at the edge close China Stone Crusher Manufacturers, the two graphs high stress areas distribution patterns are similar. Visible is the top surface of the applied crushing teeth superimposed loads, resulting in higher crushing front tooth root stress.

top loading stress distribution side is loaded by the visible, the maximum stress in the load surface of the tooth root, especially near the broken front tooth root angle, the stress concentration is more obvious, the maximum stress value of 642MPa , lower than the allowable stress values. Stress distribution on the back is loaded, the maximum stress value of 355MPa, appears in the middle of the front teeth broken at the root portion. From the point of view of the shape of broken teeth, top and back surfaces when loading, both of which can have an effect on the front of the tooth root torque, thus forming a front tooth and the root portion of the top surface of the broken blade high loading stress distribution area. While the side load on the side of Akane generation torque Mini Stone Crusher Price, the formation of high stress areas at the side of the tooth root. Since the side surface is inclined forward at an angle, the torque applied to the front side surface of the tooth root portion is larger than the torque acting on the rear of the formation of the stress distribution.

According to industry estimates, China’s overall mining machinery and the international advanced level compared to the 15 to 20 years behind. In the 1990s and reached the contemporary international level products, its technical origin mostly in the mid-1980s with the introduction of foreign advanced technology and lower foreign technical cooperation, the continuous digestion, absorption and improve products and services. Domestic market mining machine products in the market share of less than 80% in import products are mostly big Closed Circuit Cone Crusher Manufacturer, fine, sharp and complete sets of strong products, such as Shearer, efficient separation equipment and large-scale crushing and grinding equipment and the whole section joint boring machine and other products.Mining machinery will slow down the pace of developmentAccording to authoritative estimates that China’s economic development in the mid-industrialization, biasing, with respect to speed in terms of economic development, there may be 5 to 10 years or so will finish the road to industrialization. In the process of industrialization in the field of mining machinery, including both infrastructure, there must be a big development, this is a historical opportunity for mining machinery industry. But technology based mining machine industry is not thick, since the reform and opening up, has been in the field of mining machinery market for technology as the main way to improve the level of product technology, will face foreign competitors, especially foreign competitors in the domestic investment to do plant grim situation Carbon Black Raymond Mill. Some experts predict that the pace of development of mining machinery will slow down, so now begin to consider the needs of the post-industrial era mining machinery domestic and foreign markets and not too early.Throughout the development process of countries in the world mechanical design, generally a stand-alone product design – a stand-alone product design process – process design evolution process of complete sets of equipment. Since the division of labor under the system of the past, the general mining machinery manufactured only stand-alone product and manufacturing process design, equipment design done by professional design institutes, stand-alone product technology requirements and to assist manufacturers also made by professional design institute carry out. This has resulted in disjointed equipment manufacturers and equipment sector, to coordinate their contact is through so-called intermediate users (professional institute).Today, medium-sized mining machine manufacturers design department has a stand-alone product design and process equipment design features, thus avoiding the manufacture and use of touch, but also in the internal development of new products will be formed to promote Dry Mortar Production Line technology to research new technology to promote a virtuous cycle of product development, easier to adapt to today’s large-scale mining machinery, as well as the development trend of continuous automation and intelligent.

Caution rotary kiln

Posted: December 28, 2015 in nonmetallic ore

rotary kiln main drive since the DC motor starting torque, speed performance Jaw Crusher Machine In Zimbabwe, a low investment costs, in the domestic cement kiln commonly used direct current drive. Main drive configuration and control principle 1 unit rotary kiln consists of DC motors and DC drives. DC motor to use more special motor Z4 series rotary kiln, now widely used variable voltage control mode, that is, by changing the armature voltage to change the motor speed, thus changing the kiln speed. DC converter control system analog and digital control system.

2 rotary kilns principle of selection has the following characteristics, namely: a rotary kiln at the start, because of their own and thermal reasons, the required starting torque is large, corresponding high starting current, but not high current during normal operation. Rotary kiln when to stop, there is the phenomenon back to the kiln. In an instant stop the kiln, kiln shell reversed due to inertia, kiln speed reducer side is transmitted from the motor, the armature is fast, and instantly make the motor run power state, if the exciting current constant, high anti-electric potential, in exchange surface to form burn marks, even commutator will hit the pits, affecting the service life of the commutato Jaw Crusher In Turkey.

For these reasons, direct drive rotary kiln, the choice of DC converter, and a control program for components and DC drive DC motor means are required. 2.1 Motor selection based on the characteristics of the cement kiln, each DC motor manufacturers generally have dedicated kiln model, and, usually due to a host of kiln rated speed is not high, if the motor comes with fan cooling effect is not good, usually retrofit forced cooling fan to enhance cooling. DC converter rectifier elements 2.2 Selection of basic DC converter using thyristors, SCR itself due to poor flow capacity, the selection should be considered a sufficient margin.
