Detailed Product Description: | Recycling of slag also handle relatively backward state, compared with other developed countries, China's steel slag recycling rate is only about 10%, after the national "Twelfth Five-Year Plan" put forward the development strategy, and gradually improve the comprehensive utilization of steel slag was put on the agenda, some companies began to use steel slag mill ball mill slag processing, benefits of doing so is to bring all steel slag effective use, and without any waste, to solve the existing occupancy due to slag processing issue a lot of farmland and land, but also for society brought great social and economic benefits. At present, China's steel production capacity ranks first in the world, a large production of self-evident, however, as in the steelmaking process will emit large amounts of slag, and slag is an industrial solid waste, if it can not be effective and reasonable use, would be a huge waste of energy, China will freshman year 84 million tons of steel slag, steel slag can be used in many areas because of the potential hydraulic, high yield and low cost to become the first choice for the production of cement mixed materials, also can be used for mixing asphalt pavement aggregate material layer. Fine grinding mill particle size range of material handling equipment narrower than the small grinding, fine grinding mill feed size is generally not more than 0.3mm, even a small part to 0.1mm, grind particle size up to 0.074mm, the grinding ratio of only 4.1 Even when grinding mill equipment to 0.038mm, grinding ratio is only 7.9, while coarse grain size usually give mine up 10 ~ 20mm, part processing plant even up to 25mm above ground to particle size when compared to 0.3mm grinding grinding ratio is much larger than 33.3 ~ 66.7 mill when finely ground, due to the narrow size range finely processed for grinding media size choice put a higher demand, while the ratio of media types and requires less. With the impact of the original ore hardness grinding granularity grid tapering gradually weakened mill manufacturers, and the impact of the product fineness gradually increased Xinjiang grid ball mill, due to the uneven nature of similar ore ore particle size and mechanical properties of the more coarse the more micro-cracks mechanical strength worse, the more easy to wear plaid ball, and the mechanical strength of the particle size the more details the better, the more difficult ground, with 3 ~ 0mm quartz and calcite (Mohs hardness of 7 and 3, respectively) were ground under the same conditions broken, so that they are ground to a 0.04mm account for 90%, the hard quartz needs 80min, 50min and soft as long as calcite lattice tube mill, shown to affect the hardness of the fine grinding efficiency persists, addition, and with two of the same material a thickness level under the same conditions the same time the grinding results newborn less than 19um particle yield is produced after coarse ground level, less fine level produced, the more difficult to prove a particle size more fine grinding. You can see by the relevant conclusions, when for hard and soft calcite quartz finely ground, the more products worn thin, thin gap freshman level yield smaller, more fine granularity proof grinding, ore hardness waning influence while the impact of product fineness gradually increased, the reasons for this phenomenon, partly because the particle size after thinning, macroscopic and microscopic cracks particles decreases, the particle is relatively homogeneous, and defect reduction, so that even a soft mineral The intensity increased. Grid ball mill, grid ball mill, Dahua machinery provided by Gongyi City Dahua Machinery Limited. Gongyi City Dahua Machinery Co., Ltd. (www.dhqmj.com/) strong, credible, in Zhengzhou, Henan's industry-specific equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Dahua machinery and you hand into the brilliant, for a better future! |
