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.

Maintenance and storage method of vibrating screen motor and common troubleshooting

The service life of the vibration motor determines the operating life of the entire screen. Therefore, in the normal production, we must always pay attention to whether the working state of the vibrating screen equipment is normal, whether the vibrating motor is in good working condition, timely check and solve some small abnormalities and faults, and do a good job of cleaning and maintenance, because this can greatly increase the vibration screening. Machine and vibration motor life. dewatering screens supplier Maintenance storage precautions during vibrating screen motor operation The equipment can not be completely dust-free, but also has a harsh environment and dusty conditions. The vibration motor is airless and heat-cooled. It relies on natural cooling, so it must be specially maintained. The following is the maintenance content. 1. It is necessary to pay attention to whether the vibration is abnormal during the use process; 2. Always check if the bolts used in the m...

300t per hr chalcopyrite washing equipment

Chalcopyrite is a copper-iron sulfide mineral. It often contains trace amounts of gold and silver. Crystals are relatively rare and are tetrahedral-shaped, mostly irregular granular and dense massive aggregates, as well as kidney-shaped and grape-shaped aggregates. Copper yellow, often dark yellow or mottled. The streaks are black with a greenish tint. Chalcopyrite is a relatively common copper mineral, which can be formed in different environments, but it is mainly the product of hydrothermal action and contact metasomatism, and it can often form deposits of a certain scale. The origin is all over the world. In industry, it is the main raw material for copper smelting. In the field of gemology, it is rarely used alone, occasionally as a substitute for pyrite. In addition, it often participates in the composition of some colored stones, inkstones and jade. The high-efficiency spiral chalcopyrite washing machine is mainly used in the washing, grading, impurity removal, and the washing o...
