The output value of the mining machinery can be an average annual increase of one billion Yuan, and it is increasing in the domestic market share.In a long period of time, due to the domestic producers have not yet mastered the technical to design and manufacture mining machinery and equipment with large-scale and high-end, the share of foreign equipment market in the domestic market is relatively high. However, with more and more emphasis on technology research and investment in the past few years, the quality of China’s mining machinery products (cone crusher and vibrating screen) changed significantly. The emergence of a large number of large-scale, state-of-the-art products with independent intellectual property rights greatly narrowed the technology gap with advanced countries. With the accumulated experience and support of national policy, we can be competitive in international trade with the advanced countries, by virtue of price, service and quality.Due to the above reasons, mining machinery products in China’s trade surplus encouraging situation. Dependence of imported equipment for mining machinery market in China is getting smaller and smaller. In further development of the process, the overall trend of the mining machinery industry exports will further expand, while imports will be gradually reduced, the import and export trade deficit narrowing trend will become increasingly evident. However, the domestic mining machinery shall continuously research new technologies. If mining industry wants to narrow the gap of imports and exports, it is necessary to carry out technological innovation, improve mineral utilization and mineral processing, change the case of high pollution and high consumption.Performance Improvement of Jaw Crusher PlantPosted: 18 Jun 2013 12:18 AM PDTThe first stage of size reduction of hard and large lumps of run-of-mine (ROM) ore is to crush and reduce their size. Softer ores, like placer deposits of tin, gold, mineral sands etc. do not require such treatment. Large scale crushing operations are generally performed by mechanically operated equipment like jaw crusher equipment, gyratory crusher and roll crushers.LD series jaw crushing plants (crawled mobile jaw crushing station) are the best solution of demolition recycling which heavily emphasizemobility and efficiency. The compact design ensures LD series crushing plants have the best transportability andmore crushing capacity. From the rapid pace of economic development, we can see that the low carbon development is not only related to the “people"s livelihood”, but also the “national planning”. With the rapid development of blast furnace, jaw crusher equipment has also become an indispensable device in its development. The blast furnace can be processed into a variety of materials through various processes, and the following materials can be utilized effectively in different industries after processing by jaw crusher and grinding mill. Meanwhile, the technology also can make mention titanium residue to be reused, and fundamentally eliminate the residue pollution on the environment. The blast furnace is an industrial solid waste discharged by blast furnace process, also known as blast furnace, which can be divided into the steelmaking pig iron, foundry pig iron, and ferromanganese and so on. As the metallurgical industry emissions up solid waste, if the blast furnace can’t be used efficiently and rationally, it will take up the national land resources and cause waste pollution. Hongxing mining crusher will grasp the opportunity to keep up with its development so as to better development of its own enterprise. In order to accelerate the upgrading of mature products, we will make full use of scientific and technological achievements; focus on improving product reliability, suitability, ongoing technical, structural and process innovation; accelerate independent knowledge innovation; make new structure, new technology, high-tech, intelligent patent apply to mature products; as well as improve the technical performance and added value of the products of mining machinery and equipment, to boost the rapid development of China mining industry.Analysis of Working Stability of Ball Mill BearingPosted: 18 Jun 2013 12:16 AM PDTLarge-scale development of ball mill has become the fashionable trend for ball mill, and the whole technological innovation in ball mill has been imminent. The change of the bearing will be a ladder for the progress of ball mill. Due to the large-scale trend of ball mill, the working stability of bearings, key component, will directly determine the normal run of ball mill. Developing from traditional small ball mill to the current large ball mill with cylinder diameter of 7 meters, the main bearing includes ordinary plain bearing, roller bearing, hydrodynamic bearing, static and dynamic pressure bearing and hydrostatic bearing. Hydrostatic bearing is widely applied in ball mill machine for its high reliability, long life, small energy consumption and large carrying capacity. Whether in stationary state or rotating state, ball mill achieves full liquid lubrication by a thicker oil film which is formed under the effect of outside high-pressure oil between the bearing and hollow shaft. There is a small difference between hollow shaft speed and hydrostatic bearing lubrication as well as oil film pressure; when ball mill is working, bearing and hollow shaft are always in pure liquid friction and lubrication state, so it is difficult to polish bearing bush. And the carrying capacity of the hydrostatic bearing is related to the oil pressure: increasing the oil pressure could enhance carrying capacity of the oil film. Due to the hydrostatic bearing works in the pure liquid lubrication state, the friction surfaces don’t contact each other directly, thus it has small wear, long life and, in theory, can get infinite life.Ore-dressing equipments mainly include cement mill,ball mill,rotary dryer,flotation machine,etc. Now, people put forward stricter requirements of ball mill, technological innovation has been the key to win the market share. Hongxing machine keeps innovative on the road to create better equipment for customers.The Processing Application of Hydraulic Cone CrusherPosted: 18 Jun 2013 12:15 AM PDTThe traditional cone crusher is of spring type, and the spring is regarded as safety device. The earliest hydraulic cone crusher is not really hydraulic. The hydraulic cylinder is just used as safety device instead of spring. The real hydraulic cone crusher is different in inner structure. First, the move state of main shaft is different. The main shaft of old type does cranking motion. However the main shaft of hydraulic type is fixed, it can progress the move frequency of movable cone and improve crushing efficiency. In addition, the discharge opening can be adjusted automatically. The gear ring on the upper side of the machine turns driven by hydraulic system, which leads to the moveable cone close to or move away from fixed cone. Then the discharge opening is changed.

Artificial sand is also named manufactured sand, which is widely used as the highway pavement material, sand and gravel aggregate for high speed passenger railway line, hydropower station, port, and airport pavement. With the vertical impact crusher, DSMAC artificial sand making line has unique advantages of high aggregate quality and the content of thin and flaky grains less than 5%. Highway pavement is asphalt pavement, and in the construction management of asphalt pavement, as long as the raw materials and the number is adequate, road construction have the chance more than 70% to build well, therefore, asphalt pavement with good quality needs a guarantee of stable quality coarse and fine aggregate. Natural sand has light round particle, which is good for enhancing the workability of the asphalt concrete, but its poor adhesion with asphalt will reduce water stability of asphalt concrete. The mechanisms sand is able to overcome the defects of natural sand. Compared with natural sand, mechanisms sand has the following advantages: regular in shape; less flakiness particles; less dust content, and the mechanisms sand can increase the friction between the particles; has obviously high temperature resistance to rutting; can enhance the adsorption capacity of the stone and asphalt; increase thickness of asphalt film; provide good stability to the pavement. Under external disturbances in high temperature, the internal mineral aggregate particle arrangement changes, at the same time, a wealth of edges and corners strengthen the role of pellets embedded squeeze; the friction resistance of mechanisms sand enhances the asphalt mixture resistance in high temperature, deformation capacity, water stability and slip resistance; surface roughness, angularity; Therefore, sand making machine or sand maker is beneficial to the construction of the highway for speeding up its pace and ensuring its quality. For asphalt pavement construction, highway asphalt pavement with smaller traffic can be prepared with S-15 fine aggregate. In addition, the right mineral aggregate of 0.075-0.15mm and 0.15-0.3mm must be retained in production of sand mechanism, and mechanisms sand must be produced by dry type.The Outstanding Meaning of New Sand MakerPosted: 18 Jun 2013 12:12 AM PDTSand maker is widely used in all kinds of mineral, cement, cohort, bauxite chmotte, carborundum grain, glass raw material, machine made construction sand, stone stock and all kinds of llurgy slag, especially carborundum, sintered bauxite, magnesite, and so on material with features of very hard and anticorrosion.
