Hydrocyclone To introduce the manual operation of hydrocyclone in the concentrator, due to the inability to understand the changes of key process data and real-time adjustment, as well as frequent changes in ore properties, the failure rate quotient of hydrocyclone is caused, and the index fluctuates greatly, thus affecting the working effect.

It mainly shows the following aspects:

(1) as the power selection of ore feeding pump is usually based on heavy load, the high power is far greater than the working power. The liquid level or ultra-low condition often occurs in the feed pump pool, resulting in the intermittent ore feeding flow of hydrocyclone, and the quality of the final product is unqualified, especially when the ore feeding flow is lower than the critical value, the ore feeding flow directly flows into the ball mill from the grit chamber to promote the ball mill to pass through Load affects the stable operation of grinding and classification system.

(2) feed pump motor, lack of adjustment method, will cause unnecessary loss of electric energy.

There is no reliable protection measures for the feed pump.

(4) the liquid level of the pump pool will overflow out of the pump pool.

In the process of beneficiation, the main function of hydrocyclone is to expand the size by stages. The fine bottle will enter the next standard, and the requirement of hydrocyclone control system of concentrator is that the particles with qualified particle size can be reground to the previous process to ensure the stability of pump pool liquid level and feed concentration.

Because of the various problems of manual operation and the strict production target of hydrocyclone, the concentrator seeks an optimized and stable control mode to control the hydrocyclone.

With the development of science and technology innovation, hydrocyclone manufacturers are constantly innovating. One of the unique improvements is to add a siphon device on the top of the overflow box of the cyclone. What can this small siphon device do?

Siphon is caused by the attraction and potential difference between liquid molecules. It uses the pressure difference of water column to raise the water level and then flow to the bottom. Because the water surface of the nozzle bears different atmospheric pressure, the water will flow from the side with high pressure to the side with low pressure until the atmospheric pressure on both sides is equal, and the water surface in the container becomes the same height, and the water will stop flowing. Using siphon phenomenon, the water in the container can be quickly pumped out.

By adjusting the siphon device, it can help the hydrocyclone to reduce energy consumption. The pressure required by the fluid at the outlet is smaller than that required in the ordinary hydrocyclone, and the required inlet pressure is correspondingly smaller, so the total energy consumption is reduced; It can also help hydrocyclone to improve underflow concentration, and obtain higher underflow concentration and lower overflow concentration. Underflow concentration can exceed 65, and overflow almost discharges water; It can also ensure that the overflow of hydrocyclone does not run thick, adjust the siphon, let a small amount of air into the cyclone, change the upward suction of the hydrocyclone, and drive the fish tail device to shrink and close. Select the appropriate underflow and overflow concentration, and there will be no coarse phenomenon. This is the siphon device in the hydrocyclone, small device has great effect.
