Aggregate washing Machines are mainly used in building site, gravel plant, concrete dam building site of hydropower station, etc. Its new seal-structure and reliable driving device can make sure the cleaning effective and a kind of high efficiency sand washing equipment matched with the Sand Making Machine., and with features of high degree cleaning-up, reasonable structure, large capacity, low power consumption, small loss of the sands during the washing process, especially for that the drive parts of the Aggregate washing Machine is separated from water and sands. So that it has lower failure rate than the usual washing Machine.Aggregate washing Machine is a kind of wheeled washing equipment, and can clean and separate the dust and powder from the sand.

Sulfur dioxide gas, for example, is captured and turned into sulfuric acid ― which is then used in the extraction process. To do this, the copper ore is crushed then it must be roasted to convert sulfides to oxides, which are smelted to produce matte. For economic and environmental reasons, many of the byproducts of extraction are reclaimed.As in all mining applications, the ore must usually be beneficiated. Finally, it undergoes various refining processes, the final one being electrolysis.

In the conditions of declining industrial high-quality reserves of phosphorus-containing ores, issues of a more comprehensive and in-depth study of the mineral and material composition, as well as improvement of existing technologies for processing this type of raw material, become urgent. The study of the influence of the mineral raw materials composition on the features of the beneficiation schemes construction is given in the works of many authors (Aleksandrova et al. 2012; Gerasimova et al. 2017). 2006; Mitrofanova et al. 2018; Litvintsev et al. 2012; Evdokimova et al.

, SSABET (Figure 6d), that does not sum each particle surface but directly integrates the total surface area of the powder available to gas sorption.A first set of data compared the SSA obtained from the laser granulometer (an integration of the surface of all detected particles, assuming spherical shapes) after different intensities of mechanical de-agglomeration: SSAagglo (no de-agglomeration step, Figure 6a), SSAD-LG (ultrasonic de-agglomeration using the integrated granulometer system, Figure 6b), SSAD-EP (ultrasonic de-agglomeration using an external probe, Figure 6c).e. We also performed another type of SSA measurement, i.
