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.

Slove method of the clogging of trommel screen sieve

The drum screen is a simple screening device. The trommel screen is easy to close and collect dust, the maintenance is small, the maintenance is simple, and the service life is long. It is a device frequently used in refractory materials, coal, river sand classification, and sandstone classification. The advantage of the trommel screen is that the structure is not complicated so that the device can be quickly operated, and when the trommel has problems, people can easily solve it. But what should I do when the screen of the trommel screen is blocked? The following screen will introduce several ways to solve the phenomenon of blocking the net. The trommel screen sometimes adopts a mechanism added to the fixed frame, and then the mechanism rotates to drive the belt mounted on the belt to continuously smear the surface of the sieve hole, thereby sucking out the raw material particles blocked in the sieve hole. One of the disadvantages in practice is that it produces a lot ...

Several types of flocculation tanks

The concentrator is a continuous working concentration and clarification equipment. It is mainly used for dehydration of fine and tailings pulp in wet beneficiation operations. It is also widely used in the concentration of solid slurry in coal, steel, chemical, building materials, water sources and sewage treatment. And purification. The ordinary concentrator works reliably, has low operating costs, and can store and buffer the feedstock. However, it is based on the gravity sedimentation of the particles. The sedimentation velocity is proportional to the square of the particle diameter, which is used to treat the microparticles and has low efficiency. The high-efficiency concentrating machine mainly uses the reasonable use of flocculant and the cloth feeding method at the bottom to increase the sedimentation speed, which is one of the most important progress in the concentration technology. Different type of flocculation tanks Thickener tanks , Deep Cone Thickener, Sludge Thi...

How to desilting municipal drains and canals?

The river channel sludge filter press is a special equipment, which is used to deal with river channel dredging sludge, lake sludge and sludge brought ashore by cutter suction boats. The equipment adopts the principle of automatic water removal and extrusion dehydration. First, the sludge is introduced into the equipment through a slurry pump, and after pressing and squeezing, the output is clear water and mud cake. This treatment method does not require manual unloading, and the moisture in the mud cake is effectively removed, which can be directly packaged and transported, and the clean water produced can be directly discharged. Automatic processing: The equipment adopts an automatic control system to realize automatic water removal and extrusion dehydration without manual operation, which greatly saves labor costs and time.
