Most of the ceramic particle reinforced steel matrix wear resistant composite materials are prepared the surface composite material. Recently, our company and Zhengzhou University Joint successful Researched the low alloy steel / Al2O3-ZrO2 the honeycomb ceramic composite materials research and applications, won the second prize of the year 2012 Henan Industry and Information Technology Achievement Award, cellular ceramic composite causes a high degree of concern of wear-resistant materials industry again. According to the identification results of Science and Technology Department of Henan Province, they give the scientific and technological achievements state-of-the-art technology of the project, process, low alloy steel / ZrO2Al2O3 honeycomb ceramic composite technology and its application in low-impact load liner innovation Habitat leading domestic level.expert opinion, which will play a huge role in promoting the development of wear-resistant materials industry in China. Especially the resistant composite materials has experienced double-double liquid metal material in China, after several stages of high-chromium steel materials, high-chromium steel cast-mechanical combination of materials in recent years, marked by high manganese steel composite hammerhead (or cast iron) cast-carbide industrial composite production and application. Let us take the third-generation big gold tooth carbide hammerhead cast we produced as example, in the course of their work, hammer crusher crusher wear parts directly in contact with the material. In order to improve its abrasion resistance, traditional hammerhead multi the work surface coated with a layer of tungsten, titanium carbide pick stone, abrasion resistance is not high. Our company s latest achievements jointly developed with the Xi an Jiaotong University, the Joint Institute of wear-resistant materials and third-generation big gold teeth crusher hammer is used in high-manganese steel substrate cast-intensive extremely tough hardness second only to diamond tungsten titanium alloy, can withstand harsh abrasive wear, Compared to the original ordinary high-manganese steel hammer, its service life increased 30% to 100%.
Fine iron ore in China is scarce countries, almost all the required needs of the fine ore from India, Australia and through imports. After the natural ore crushing, grinding, dressing, etc. may then be concentrate, processed into a concentrate called slag. Ore mined first by the initial jaw crusher broken by the crusher to a reasonable degree of fineness by the after elevator, even into the mill to the mine machine, crushed ore from the grinding mill. The advantages of Hammer crusher: high crushing ratio (general for 10 to 25, Flotation separator, and other machines are the stone crushing equipment, individual can be up to 50), this is its biggest characteristics. Second, it s simple structure, compact size, Cone crusher and other machines are the main ore dressing equipment on the market. the body s light weight, easy operation and maintenance.
In addition, its product size small and even, to less crushing. Great capacity of production, low energy consumption per unit of output. The disadvantages of the Hammer crusher: Hammer crusher work parts (such as the hammer, article deck) easy to damage, Ore beneficiation and other machines are the sand making machine, need to replace frequently, therefore, need to consume more metal and maintenance time. And then the materials are rebounded from the impact liner to the area where the hammers effect for being re-crushed. All the materials from large to small will be crushed at the impact chamber repeatedly. As a professional technology as the center of the enterprise, DuoNian driven model to the company has been committed to the mineral processing equipment mine broken drying equipment, conveyor areas of high-end development and progress.
Coal mill is used to efficiently blend varieties of coal with fuel oil to increase bulk density. Hongxing has been concerned with coal pulverized fuel for kiln and boiler firing for many years. Our coal mill pulverizer can handle all kind of different coal grades from hard coal, woody dates and dates to anthracite coal and petroleum coke, we can design and complete set of coal grinding plant from dry to grinding. Calcite is one of the most common minerals to produce calcium carbonate. The quill shaft adopts cast steel part and the liner is detachable. The gearwheel adopts casting hobbing process and turning the drum is equipped with wear-resistant liner, which has good wear-resistance. The machine is with stable and reliable working condition. Moreover, according to different materials and discharging methods, there are dry ball mill and wet ball mill for choice. There are two ways of grinding: the dry and the wet way way.
