Ring roller refiner is a relatively novel grinding equipment developed for the majority of users according to the development direction of China's grinding industry and the needs of the market. A new type of abrasive device integrating rolling, grinding and impacting, which can smoothly produce ultra-fine powder, with a particle size range of 80 3000 mesh, is a truly high-efficiency and energy-saving ultra-fine grinding equipment, especially suitable for the advanced treatment of non-metallic ores.
The annular roller grinding production line is an open design, which can effectively reduce the grinding heat of the fuselage, the powder output effect is better, and the whole set of equipment runs more smoothly. There are no rolling bearings and screws in the grinding chamber of the three-ring mill, so there is no problem of easy damage to bearings and other sealing elements, and there is no easy loosening of screws and damage to machinery.
The grinding roller and grinding ring are special wear-resistant steel, which prolongs its service life, and the main engine base is cast as a whole, which not only ensures the strength of the structure, but also has a good shock absorption effect.
This machine is an advanced processing and crushing device for fine powder, equipped with a forced swirl classifier, which has a large crushing ratio and a high energy utilization rate. It can process D97<10 micron fine powder at one time, of which about 40% of the fine powder with a particle size of less than 3 microns has a high specific surface area; It has the characteristics of high efficiency and low energy consumption, in addition, it adopts a full pulse dust removal mode, and each filter bag is separately dusted through compressed air, which avoids the blockage caused by the dust accumulation on the filter bag for a long time, so that the dust removal efficiency reaches 999% or more. The grinding wheel and grinding ring of the whole machine are special wear-resistant steel, which has a long service life and good shock absorption effect, which is a booster to promote the development of dry desulfurization technology in the steel industry.
