Product Brief
Intelligent Tailings Filling Package Equipment
Intelligent tailings filling package equipment is an internationally advanced device for unclassified tailings thickening and dewatering and vertical bin-type tailings thickening that is independently developed by China ENFI. It is applicable to underground filling, filling control of open-pit and mined-out area and tailings thickening & discharge.The low-cost and high-quality thickening and dewatering of unclassified and classified tailings has been realized in the mine filling process.
Specification & Series：The device features 2 specification/series of Φ8.6m and Φ10m diameter, which can meet the demand of most medium and large-scale mines with cut-and-fill stoping method. The device can also be customized based on customer needs to meet personalized demand.
- Processing Capacity：Tailings thickening storage device can process the tailings slurry at a flow rate of 200 to 700m³/h, with the flow rate of discharged underflow as 60 to 160m³/h.
- Application Fields：The device is applicable to metal and non-metal mines with cut-and-fill stoping method. It is applied to the mine fill and tailings disposal, applicable to the disposal of unclassified and classified tailings、In-pit fill、Tailings thickening and discharge、Open-pit backfill.

Advantages & Features
- Wide adaptability and strong surge capacity. It is applicable to both unclassified and classified tailings as well as thickening and storage of crude and fine tailings. It also features a large surge capacity in tailings storage, which can solve the matching problem of beneficiation production and filling operation in mining.
- Good thickening effect and closed-circuit recycling of overflow water Compared with the preparation effect of traditional vertical tailings bin, the discharge density of tailings bin increases by 3%-18%, characterized by a sound continuity of tailings discharge and stable flowrate. Cemented filling slurry reaches a paste state with a low bleeding rate and high strength of fill mass. Simultaneous operation of overflow dewatering at the top of equipment bin and slurrying at the bin bottom enhances the filling capacity and realizes the purpose of closed-circuit recycling of mineral processing water.
- There is no rake frame, which is energy-saving and environment-friendly;
- All mechanical parts of package equipment can be made by steel structural members characterized by fast construction and convenient installation.
Working Principle
Intelligent filling automatic control technology is adopted. And intelligent algorithm is made based on the short-flow process to optimize and adjust key parameters including various level, flow and metering, etc. By self-adaptable intelligent process analysis and APP mobile terminal, the undisturbed switching between manual and automatic control is realized so as to accomplish “one-key filling” and ensure efficient and stable operation of filling production with remarkable benefits. Automatic filling control system performs a comprehensive analysis of various parameters in the filling process to produce production statement and statistical analysis diagram of production data, which simplifies process flow, enhances filling quality, lowers filling cost and investment, reduces manning and facilities management and maintenance.
