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.
