The role of tailings dehydrator in dry tailings discharge
2021-10-08
At present, the problem of comprehensive utilization of tailings in my country is that the utilization rate of tailings is low, and many areas still lack the proper awareness of dry discharge treatment of tailings. Poor awareness of tailings pollution prevention, and insufficient technical input for dry tailings treatment.
Advantages of dry tailings discharge
1. The use of dry tailings to fill the mined-out area technology solves the problems of environmental pollution, potential safety hazards and large amounts of land occupied by traditional tailings discharge tailings.
2. After the tailings are concentrated and dehydrated, they are discharged in a dry manner, which not only saves the construction costs and conventional maintenance costs of the traditional tailings pond, but also makes full use of the self-flowing backwater, and it can also greatly save the area and eliminate the tailings pond. Safety hazards. In addition, in the mine production process, the hidden safety hazards in the goaf can be eliminated, safety investment can be saved, landform restoration can be reclaimed, environmental governance funds can be saved, geological protection is conducive to environmental protection, and waste replacement can be realized.
3. The equipment, technology, and process used in the dry tailings discharge process are innovative, which opens up a new way for the comprehensive management of tailings stacking and goaves.
4. Low investment and great benefit. According to calculations, after adopting the technology of dry tailings to fill the mined-out area, it saves investment in fixed assets, saves funds for safety management, funds for ecological environment management, energy conservation, and emission reduction, and maintenance costs for tailings ponds.
Advantages of tailings dehydrator
1. Tailings dewatering screen, also known as tailings dewatering machine, has a good effect on iron tailings treatment. Generally, iron tailings slurry with a concentration of 18%-30% can reach the solid content on the screen after being processed by the dewatering screen. More than 85%, even some coarse-sand iron tailings can reach more than 90%, which can reach dry piles, and some of the water under the sieve can be recycled after precipitation.
2. LZZG tailings dehydrator is a vibrating screen specially developed for dry discharge of metal tailings in combination with the characteristics of metal tailings. It is suitable for the dehydration and dry discharge equipment of materials with small particle sizes, such as fine sand, tailings, and tailings. Mainly used for dehydration of iron ore, copper ore, gold ore, and aluminum ore tailings. It is a new type of high-efficiency tailings recovery equipment designed after full demonstration and investigation in response to many problems existing in a large number of dry tailings screens in my country. It has a simple structure, low cost, high efficiency, low energy consumption, low noise, and convenient maintenance. Features. Compared with the ordinary linear vibrating screen, the tailings dewatering screen has the advantages of large processing capacity, good dewatering effect, low moisture content of the finished material after dewatering, wide application industries, and high-cost performance.
Features of tailings dehydrator
1. It adopts the principle of self-synchronization, the motor drives the vibrator through a tire coupling, with simple structure and low working noise. High working frequency, high vibration intensity, low moisture content of the product on the screen, high unit processing capacity, and high solid recovery rate when used for tailings dewatering. To adapt to the differences in the properties of different tailings, the amplitude of this screen is adjustable by adjusting the angle between the main and auxiliary eccentric blocks to meet the dehydration effect of tailings of different properties. The screen surface of the pre-dewatering sieve plate is installed at 45 degrees from the horizontal, and the dewatering sieve plate is installed at a negative inclination angle to increase the dehydration area and promote the dehydration of the material as soon as possible to form a filter layer.
2. To facilitate the maintenance and replacement of the screen surface, the screen surface adopts a rail seat type installation. The use of polyurethane elastic screen surface, high open rate, and elasticity are conducive to dehydration. The side pressure plate of the screen surface is made of polyurethane material, which has a long life, and the screen surface is fixed and reliable, and can effectively protect the side plate of the screen frame from being washed by materials. The side plate and the beam are connected by torsion shear-type high-strength bolts, and there is no welding seam, which avoids the problem of side plate cracking caused by welding stress. The vibrator is an eccentric unit-body structure, which is easy to disassemble and maintain. The bearing adopts special bearings for vibration equipment to avoid premature damage due to heating.
