More DetailsFlotation machine (also called flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc.
More DetailsStirring tank is suitable for mixing before flotation, for various metal and ores to adequately mix pharmaceutical and pulp, and it can also be used for mixing other non-metallic minerals.
More DetailsThis series screen is always used in processing minerals such as ferrous metals including hematite magnet and nonferrous metals including lead, zinc, gold and silver, etc.
More DetailsSpiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.

More DetailsMilling Formulas. Speed (RPM) = (SFM x 3.82) / D. Feed (IPM) = RPM x FPT x Z. SFM (Surface Feet per Minute) = (RPM x D) / 3.82. IPT (Inches per Tooth) = (IPM / RPM) / Z. MRR (Cubic Inches per Minute) = IPM * WOC * DOC. AFPT (@ less than 1/2 dia. WOC) = IPM x sqroot of (D / WOC) HP (Horsepower Consumption) = MRR x mf. mf - steel = 1.
