High pollution and high energy consumption is our first impression on the cement industry. With our country’s increasingly value to the environment, in the next few years, the cement companies will not only be faced with the demand to reduce costs and improve the enterprise efficiency; but also will attach importance to the energy saving work. In recent years, through the integration and reform of the government to the cement industry, the energy consumption and material consumption of some cement companies has been greatly reduced, but compared with the international advanced level, the gap is still existing.
The cement industry keeps flourishing this year with the production exceeding 2 billion tons last year. In the year of 2011, investing programs focus in the industry of transportation, major projects, city construction, etc. In the beginning of “the twelfth five-year”, all the local governments, in order to achieve continual development in economy, have new plans for investment which will definitely promote the demands for cement products.
Presently, the cement industry is featured with inappropriate layout, lagging technology and equipments renovation, which will inevitably result in low production and fierce market competition. Raw materials for cements mainly include lime and clay. According to the kind of fuel and cement, other materials will be added to complement the shortage of certain ingredients. The industrial wastes can also be used as the raw mixed materials in cement production. In the process, most raw materials should be crushed. Limestone, as the major material for cement production has large size and high hardness after being mined. The common crushing equipments for limestone include hammer crusher, jaw crusher, impact crusher and cone crusher. To a service-oriented brand integrity, as the professional manufacturer of complete sets of mining machinery, like magnetic drum separator, Henan Hongxing is always doing the best in products and service.gyratory cone crusher: http://www.hxjqchina.com/n106.html
To make the process more economical and convenient, it is crucial to select appropriate crushing and grinding equipments. Before grinded, materials are suggested to be crushed for fine and uniform size in order to release the pressure on grinding equipments and increase the production. In the year of 2011, the hyperbaric grinder and hyperbaric trapezoid grinder, specifically for large-scale cement production, was designed and produced by Henan Jianshe Luqiao Machinery Co,. Ltd.. In the production line of cement, the grinding process takes up 60 percent of the total amount, among which the grinding of green stock, coal and cement respectively cover about 30%, 3% and 40%. Therefore, it is quite necessary to select crushing and grinding equipments and technical process, improve the technology and make proper operation to ensure the products quality and decrease the power consumption.
。In the “twelfth five-year”, the cement industry structure adjustment focuses on merging and reorganization. Those top 10 company will contribute 40 percent of the total domestic production and their profiting capacity will also be enhanced. In the year of 2012, ideas of energy-saving and emission reduction will continued to be promoted in cement industry and industrial chain will be further extended. Investment in the sandstone aggregate production will not only reduce the capital and protect the environment but also improve the overall competitiveness of cement industry.
