subject: Mineral Processing Equipment Crusher Market Development [print this page] Mineral processing equipment crusher market development_Ivylm522 while the fracture of the Ming and Qing to the Republic, the purple mud ore mining and processing of soil and methods are primitive stale: stale, also known as "trapped mud, the mud piled up in the dark and damp, warm, closed chamber for a period (days to months), so that mud from the series of physical and chemical changes in a humid environment ball mill manufacturer and not to take the air, this could make the mud with improved performance, such as wetting and uniform moisture, the organization is more dense, enhanced plasticity, Dry Strength and mechanical strength of products increased, thereby reducing cracking mill manufacturers in sand equipment the molding process and when the green body dried by weathered clay has the following characteristics: clay texture thinner, improve plasticity, uniform moisture in the raw materials, some of the alkali metals and alkaline earth metal salts dissolved, fire raise the degree of vacuum degree should acquire the appropriate, generally from 700 to 740 mm Hg Impact Sand wheel grinding is the use the grind round and Nianpan of the relative motion on the Nianpan material repeatedly RCC, also play a mixed mud the role of material addition, the fight mud is very particular about the different mud juxtaposition, adding an appropriate amount of oxides, will produce a variety of color changes, the formation of many new kinds of mud, the mud of such corporation, cinnabar mud vegetables tomato mud, beans Bi mud, dark green mud, days of blue mud, green hollow block machine mud, the loquat yellow, Kwai Wong Nai, red eel mud, gold Osmanthus mud, Dahongpao mud, red mud, Zhuni, black iron ore and so on.
With the "15" during the construction the amount of increase, the sand and gravel industry will face even greater opportunities and challenges to the Association this year focus on artificial sand for a long period of time in the "10th Five-Year Plan" period, will in the construction market a large number of applications, which has a favorable external environment factors, First, ecological awareness, environmental awareness and resource awareness has been accepted and taken seriously, gradually reduce the depletion of some places even in the natural sand resources, the availability of alternative products ;Characters: 615 The increasing requirements of the construction quality of concrete aggregate requirements have also increased, in particular, is the aggregate of Ball mills the concrete above the C60 level to meet the requirements, building sand must be processed to meet the standards; the stone crusher technical content of the crushing and screening machinery used in the production also improved, to meet the various requirements of concrete aggregate for the production of high quality and provides the technology to ensure the development of artificial sand, the time is ripe, I believe artificial sand will be more and more, faster and faster to get the application, play a leading role of the era for a period not too far from our country can take advantage of its large amount of tailings and river pebbles sand, can protect the environment, reduce pollution, but also to ensure the quality of concrete aggregate in the country to promote the production and application of artificial sand
in the country China is beneficial to promote stone crusher the development of mechanisms of artificial sand, the need to strengthen all aspects of work: In implementing the new gravel standard, new gravel GB have been included in the artificial sand, which is the promotion of artificial sand and the legal basis of the use of artificial sand; Second, do the experimental data collection, analysis, research, and make reliable data; to actively introduce the development of advanced artificial sand machinery and equipment in the concrete and building mortars, using gravel as the aggregate of the buildings rotary kiln to account for 80% the proportion of China's more than 700 million tons of cement annually, the data indicate that and present, China's annual output of sand and gravel production reached 1.5 billion tons in a wide variety of building materials, the largest amount of material is gravel, so our construction sand and gravel needs a huge sand and gravel industry the status quo: China's natural sand resources due to years of exploitation and countries to strengthen environmental protection, rivers and endanger the Flood Control Water and Maritime ban on logging, mining the scope and number of trends, to adapt to the variety of needs of nation-building project of the new era of the new century, in addition to strengthening resource management, urgent need for new resources to replace natural sand.
