Floatation Separation Floatation is a main method to separate the ores by the different natures of wetting by water The hydrophobic mineral will be gathered on the bubbles and floats on the surface However the hydrophilic minerals will stay in the water Applies for the following oresGet Price List
Great energy conservation, wide adjustment range, low noise and little dust
Good appearance, excellent sealing, no dust pollution or leakage,few easy-wearing parts
1.5 times or even 2 times larger crushing cavity than that of other crushers, large feeding mouth
Stable performance, little noise pollution , low acicular content, no crackings inside, little wear and long service life
With features of reliable structure, high working efficiency and easy adjustment
VSI sand maker, also called VSI crusher, is the major machine for sand making plant.
Ball mill is the key machine to grind the crushed materials. Ball mill machine is widely used to process cement, silicate product, building material, refractory material, fertilizer, ceramics and glass, etc.
