Industrial flotation machines can be divided into four classes: (1) mechanical, (2) pneumatic, (3) froth separation, and (4) column. The mechanical machine is clearly the most common type of flotation machine in industrial use today, followed by the rapid growth of the column machine.
SF model is a flotation equipment that can both self-absorb slurry and self-aspirating. Working principle. When the impeller of the SF flotation machine rotates, the pulp is thrown around under the action of centrifugal force, so that a negative pressure area is formed in the upper and lower impeller cavities.
Siping Haorong Silver Co., Ltd. is a major producer of silver in China with a capacity of 520 t/d.
