Application of tail water purification system in sand washing production line

In the sand washing production line, the ore dressing operation is very important. With the increase in environmental protection in recent years and the tight supply situation of domestic mineral resources, we have to use the tailings that were once overlooked. The tailings are ignored because the residue cannot be further sorted. However, with the development in recent years, we have found that tailings are not completely useless waste, and often contain other ingredients that can be used for other purposes. The processing technology and development and utilization can effectively “turn waste into treasure”, which not only eases the resources and environmental pressure but also realizes the comprehensive utilization of tailings!

The tailings zero discharge system is a specialized treatment system specially developed for the tailings dry discharge and tailings slurry zero discharge in the mine beneficiation industry. Compared with the traditional tailings treatment method, what are the advantages and characteristics of the tailings zero discharge treatment system in the sand washing production line? I will tell you below.



Most of the domestic tailings still use wet emissions, and the tailings pond stores tailings. This traditional process has certain harm to the environment and safety. In the traditional tailings treatment, tailings dams are used together with thickeners for tailings treatment. There are many problems in such treatment technology. The main problems are as follows: the construction of tailings ponds has a large area and the safety risks are large. It has the problems of long tailings transportation distance, high investment cost, and high operating cost. The tailings sludge cannot be effectively dehydrated, the water recycling rate of the tailings pond is low, and the power consumption is large, which will cause high cost of returning water.

Sandblasting nozzle classification and use

Using high-pressure air as a power source to drive abrasive particles to hit objects within a certain range will produce a great impact. The function of the sandblasting nozzle is to spray abrasive particles on the object evenly and efficiently. Sandblasting nozzles can be divided into: straight hole sandblasting nozzle, Venturi sandblasting nozzle , double Venturi sandblasting nozzle, angle sandblasting nozzle Straight hole nozzle: There are only contraction section and straight section inside, the structure is simple and easy to manufacture. This kind of nozzle cannot overcome the vortex phenomenon existing at the inlet end, and the pressure loss is large; the abrasive velocity at the outlet is less than 100m/s under the pressure of 0.7MPa.

Working principle and parameters of industrial slurry pump

In order for the industrial slurry pump to fully play its role, we need to understand the working principle of the industrial slurry pump: https://www.lzzgmachine.com/products/supporting-equipment/slurry-pump.html Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy to leave the outer edge of the impeller at a high speed and enter the volute pump shell. In the volute pump case, the Fluid is slowed down due to the gradual expansion of the flow channel, and part of the kinetic energy is converted into static pressure energy. At last, it flows into the discharge pipe and is sent to the place where it is needed. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller. Above the liquid level of the storage tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. LZZG slurry pump pe...

The difference between quartz and mica

Mica and quartz are common minerals that play an important role in mineralogy. Although they are both silicate minerals, there are clear differences between them. First, mica and quartz are very different in appearance. One of its distinguishing features is that mica exhibits a layered structure that can be easily peeled off into thin flakes. Quartz, on the other hand, is a uniform crystal with no layered structure. Additionally, mica is usually dark in color, such as black, brown, or green, while quartz is usually clear or white. Secondly, mica and quartz also differ in their physical and chemical properties. The hardness of mica is usually between 2.5 and 4, which is relatively easy to be scratched; while the hardness of quartz is very high, 7, which is a very hard mineral. In addition, mica has good refractive properties and electrical properties, while quartz is an excellent piezoelectric material.
