Development of Ultrafine powder and selection of grinding machine
- In cement and HMA, ultrafine powder filler will on the one hand improve adhesion of concrete interface and on the other hand will make the mechanism of slurry sheology better.According to provisions of powder production,vertical mill can absolutely be used to powder processing.Vertical mill can be used to dry fly ash and process water quenched blast furnace slag.The finished product meets the requirements of cement concrete and so is expected to make up for shortage of cement.
- Traditional powder processing market generally chooses ball grinder mill and traditional raymond mill more often. Given the ultra-fine particle demand trends in the current powder application,the ball grinder mill and traditional raymond grinder mill whose finished product is a little coarse, is gradually exit out of market and instead of ball grinder mill and traditional raymond mill ,it’s various kinds of modern latest scientific ultra-fine vertical mill.
- In the test machine experiments,the finished size has already attained to granularity of thousands mesh while using vertical mill to grind calcium.In the plastic products,people usually add a certain percentage of calcium carbonate powder .In the last 90s,the percentage can up to 40-50% while in the current is 60-70%. We can see the large demand to calcium carbonate powder.Apart from 6% annual growth rate of the rubber’s demand to calcium carbonate powder,paper manufacture has become calcium carbonate powder’s second largest consumption. Apart from calcium carbonate powder,graphite、talc、gypsum、mica、kaolin powder processed by vertical mill have very good sales in foreign market with a relatively high price.With the growing development of technology, we believe the ultra-fine powder market will be much wider.Large number of low-cost raw materials have already sucessfully entered into the latest science and technology field with a image of new high-end products after being processed by vertical mill. Here you can see the development and application of ultra-fine powder is being the concern of international and domestic powder market.
- The vertical mill produced by Shibang has condensed of years of technological advances and research experiences.This grinding machine can not only implement the convenient regulation of thickness to finess powder, but also be provided with some practical advantages both in production efficiency and space.From the point of whole processing and application of powder industry, we can see new vertical mill will defenitely replace the confused grinder mill in the current market and become the selected unified product in powder processing field.
- Throughout ultra-fine powder processing market,the high pressure suspension grinder mill ,MTM medium speed trapezium grinder mill,SCM ultra-fine grinder mill and the latest MTW european trapezium grinder mill produced by Shibang have represented the forefront of current industrial grinding machine . We can choose the newly developed vertical mill to process non-metallic minerals and a wider range of ores,such as calcite, chalk, calcium carbonate, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectories, diatomite, barite, gypsum, alunite, graphite, fluorite, phosphate rock, potassium ore ,pumice, ect.
