tailings processing equipment/tailing recycling equipment

Yantai Zhongding has introduced the most advanced tailings processing system at home and abroad, which has been applied and promoted with excellent results in domestic. It has solved the major problems of domestic tailings processing . Compared with other dewatering process, power saves about 2kw.h/t, investment saves by 30-40% and the cost saves about 2 to 4 yuan every ton .

◆ process characteristics

■ The discharge methods of tailings changes from dam-type emissions to the the bulldozers field emissions, the tailings and the capacity of water are canceled. It has avoided dam failure, overtopping, collapse accidents and improved safety.
■ The economy is high, investment costs is reduced, the land acquisition cost is saved, the construction cycle is shorten and maintenance and operation cost is low.
■ It has achieved zero discharge of wastewater, saving vast amounts of water for the community and a lot of money for the enterprise.
■ The solutions of processing technology of tailings dry heap, not only can cofferdam farmland and plant trees, but also backfill the pit and subsidence area, and finally make double harvest of resource development and environmental protection
■ It's simple to manage, easy to operate, and has wide range of applications, which is suitable for concentration dry row of a variety of particle size and high concentration tailings .

◆applications examples

■ High concentration cyclone----- the core of tailings processing system

The combination of high concentration cyclone, thickeners and dewatering screen can complete the concentration and dehydration process efficiently. After concentration and dehydration, the improvement of underflow concentration can create good conditions for dewatering screen operations. It can greatly improve the capacity of dewatering screen and the lower overflow concentration can reduce the load of the thickener effectively. The Zhongding cyclone adopts the unique structural design, which is widely used in various types of concentrator. In the iron ore, even though the ore concentration is about 8%, the underflow concentration is still able to maintain more than 70%, and yield is more than 75%. High concentration cyclone has long life, good effect of concentration, high separation efficiency, easy operation and maintenance, and good wear resistance.

■ Dewatering Screen ------ important guarantee of the tailings processing system

The dewatering Screen adopts polyurethane sieve, and it"s abrasion is three times higher than the other sieve. The effect of dehydration is good, safe and reliable.Also it's weight is light, easy to disassemble , install and maintain, and the life of wearing parts is long.

■efficient thickener

Huge processing capability, good effect of concentration , small footprint, less investment, low power consumption, low running costs, easy management and maintenance.

■ device that flocculant is automatically added

This equipment allows flocculant and water to use high-speed jet to mix, the flocculant liquid produced has no block, and is all colloidal. It will not destroy the flocculant polymer chain, the adding of flocculant can make linearity adjustment from zero.

Zhongding can provide train services of the tailings dry ranked test, process design, equipment manufacturing, installation and commissioning, training of workers, and standard production .
