process of asphalt production

Ball mills are used primary for single stage fine grinding, regrinding, and as the second stage in two stage grinding circuits. According to the need of customers, ball mill can be either wet or dry designs. Ball mills have been designed in standard sizes of the final products between 0.074 mm and 0.4 mm in diameter.

By absorbing the advanced technology from the world, we researched and designed PF series impact crusher. It can be used to deal with materials whose size below 500mm and whose compression strength less than 360Mpa. Thus, it is widely used in many industries, like chemical, metallurgy, road and bridge construction and sand making and so on.

Besides the ordinary crushing & grinding machines, mining equipments also include many very professional machines, such as floation machine, leaching tank and thickener, etc.

Based on more than 30 years’ manufacture experience, millions of equipment units’ installation experience and abundant invested in research and development, SKY mining has released the K series portable crushing and screening plants, which contain 72 models that fit various crushing work in metal mines, building aggregates and solid waste treatment fields.
