In order to ensure the flotation time, it is necessary to increase the number of slots of the flotation machine or increase the section size of the trough.

If the groove depth of the flotation machine is too small, the path of bubble mineralization is shortened, and the foam layer is prone to tumbling.

From the perspective of increasing the amount of charge and reducing the amount of electrical energy, it is desirable to use a smaller groove depth.

The flotation tank of the flotation machine has two types of indirect and inflow type, indirect flotation tank, and there is an intermediate chamber between the tank and the tank. The slurry is controlled by the gate from one tank to the next, and is sucked by the impeller. The slurry tube is inhaled, so the slurry flow rate is limited.

The direct flow flotation tank, the trough is collided, there is no intermediate chamber, the ore can flow through the largest cross section of the flotation trough, and the passing capacity is large, so the direct current type can improve the production capacity of the flotation machine, and It is easy to realize automatic control of the flotation machine, but the liquid level of the DC flotation machine is not easy to adjust.

At present, most flotation machines have an intermediate chamber with several slots, so that they have the advantages of both direct current and indirect.

The tank of the flotation machine is generally square, and usually has a circular or other shape. The flotation tank can be scraped on both sides according to the side of the foam.

The bottom of the flotation cell of the flotation machine is usually equipped with a plurality of vertical flow plates. The function of the steady flow plate is to reduce the speed of the slurry coming out of the impeller and change its direction of movement, so that many small eddies are formed at the bottom of the groove, so that the ore particles remain in suspension and increase the chance of contact between the ore particles and the bubbles.

The shape of the flow plate may be radial, curved or otherwise. In the flotation cell, not all spaces have bubbles, but only those volumes containing bubbles are mineralized, so this volume is called the effective volume. The effective volume of the flotation machine is related to the agitation mechanism and the flow stabilization device.
