How does the slime affect the flotation?

April 04, 2023

If the floating mineral slurry contains more slime, flotation would bring a range of adverse effects. The main influences are as follows: 1 It is easy to be mixed with foam products, which makes the concentrate grade drop. 2 easy to cover the coarse grain surface, affecting the flotation of coarse particles. 3 adsorption of a large number of agents, increase drug consumption. 4 The pulp is sticky and the aeration conditions are deteriorated.

The technical measures to solve this problem are as follows: 1 Use a thinner slurry to reduce the viscosity of the slurry and reduce the inclusion of the slime in the foam product. 2 Add dispersant to disperse the slime and eliminate the harmful effects of the cover on other mineral surfaces. 3 sections are added in batches to reduce the consumption of chemicals by the slime. 4 The flotation material is preliminarily delimed and then floated. A commonly used desliming method is a cyclone degrading.

Slewing Controller

Slewing Controller is a kind of Tower Crane slewing control device, combined speed and voltage regulation and eddy current speed controling. The slewing control block control the speed of eddy current torque motor, to make the tower crane slewing mechanism start, working and stop smoothly. This kind of Slewing Controller is used to regulate and control the speed of three-phase torque motor of AC 50Hz, voltage 380V.

HRCV slewing controller is a hoisting slewing controller developed by our company according to service condition of customer.
The main technical feature as follows:
(1) This product combined the controller and thyristor module,the connection of the users is simple and easy.Prevent the damage of the controller and thyristor module caused by mis-wiring of the customer.
(2) Realize the best optimization of AC voltage control curve and DC voltage control curve.
(3) With the function of inching during operation, realize the accuracy.
(4) The electronic components adopt the imported industrial grade chip, on the control panel directly with power supply and direction indicator light.
(5) Adopt the coating treatment on the printed circuit board,enhance the dust prevention and anti-condensation capacity of the circuit board.
