Tailings Dry Discharge Industrial Decanter Centrifuge Machine Eco Friendly

1. What is tailings?

Tailings are the waste after the production and beneficiation of the mine. The tailings pond is used to dispose of the tailings in the mining area. It is necessary to build a tailings pond suitable for the production scale of the mine within the mining area. The investment is huge. Now the general mining plant uses the pump body to directly extract the tailings slurry to the tailings pond for storage, but because the tailings directly carry excessive heavy metals and other pollutants and residual beneficiation agents, it is easy to pollute the environment, It will also be accompanied by considerable potential safety hazards, so the state advocates the use of dry tailings storage method in consideration of the requirements of environmental protection and safety.

2. What is the dry stacking method of tailings?

Tailings dry storage method refers to the high concentration paste tailings produced after the tailings are processed by the dewatering equipment, and the tailings can be dewatered to the non-pumpable humidity. After dewatering, tailings are transported and stockpiled by dry method, and then bulldozed and compacted by bulldozer, which can form unsaturated and dense tailings pile without tailings pond.

3. What is tailings dry discharge?

Tailings dry discharge is to make the water content in tailings reach about 15% by technical means, so as to make tailings meet the requirements of dry stacking. In the mines near the water source, if the tailings dry drainage technology is adopted, the waste water can be completely prevented from entering the water source, and the dry tailings can also be used to produce building raw materials, which can create more economic benefits for enterprises, and has great social benefits, which is of great promotion value.

The horizontal spiral sedimentation centrifuge is mainly used in the field of tailings dewatering. In order to meet the customer's requirements for concentrate dewatering and tailings treatment of mining companies, Juneng Machinery has carried out technical transformation on the existing horizontal spiral sedimentation centrifuge components, so that its separation factor can reach the concentrate dewatering technology! It fully meets the requirements of mining companies for dewatering and dry discharge of tailings.

4. Working principle of special separator for tailings dewatering

After being thickened in the sedimentation tank, the ore washing sludge is transported to the mixing pipe through the screw pump in the feeding system and mixed with the flocculant prepared by the flocculant dosing system. After being flocculated, the small particles are agglomerated into large particles, and then transported to the concentration and dehydration system for dehydration. The dewatered sludge is transported to the transport vehicle by the sludge transportation system for landfill or reclamation, and the purified ore washing water is returned to the ore washing section for reuse. Reduce water waste.

This workflow is completely run by the PLC automatic control system.
