for the mining industry, our semi-autogenous grinding mill uses a minimal ball charge in the range of percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. autogenous grinding mills involve no grinding media as the ore itself acts as the grinding media.for more than years, netzsch has been one of the worlds leading suppliers of mixing and dispersing technology with its grinding & dispersing business unit. the special-purpose machine manufacturer produces several hundred dissolvers a year. these guarantee a high standard of quality and reliability in the production process. read more
high pressure grinding rolls is a mature technology that is proven to reduce capital and operating costs in full scale plants when compared to other comminution technologies. read more sgs comminution experts have developed a simple testing methodology to avoid some of the difficulties associated with using hpgr.sgss comminution experts use the sag mill comminution test to characterize ore samples, an important first step to grinding circuit design, optimization and production forecasting. read more the smc test is an abbreviated, less expensive version of the JK drop-weight test.
the process of high-pressure grinding and the properties of its product are very different from those of conventional crushers or grinding mills, and the industry has learned to use this to its advantage in new applications. today, the iron-ore industry uses hpgrs to prepare pellet feed for finishing grinding after wet-ball milling and filtering.jan 06, 2014 It has been shown, for example, that the replacement of a sag mill with a hpgr in a conventional sag-ball circuit may reduce grinding energy consumption by 1520%. taking into account additional savings, such as media and liner wear, it was found that a grinding cost saving of 2535% was potentially achievable with the use of hpgrs in such
