Description

Chengchao Iron was launched in September, ***8. In November, ***9, the project was completed and put into production with its designed annual capacity being 1.5 million tons of iron ore, which has now been expanded to 3 million tons. Our main product*-the iron powder*-has been awarded as National Metallurgical Quality Product, meeting the international advanced standard.
Basic Plans:
 
Chengchao Iron Ore adopts the full tailings filling process, in which we choose the full tailings and cement/cement substitutes as filling materials and set up two tailings warehouses and a cement silo. The full tailings use natural dewatering, overflow and drain value to drain water. When filling, it uses compressed air to produce mud and pipeline to avoid sand. The filling equipment makes use of two continuous stirring with biaxial mixer and efficient activation mixer. It drills the hole for filling and is conveyed by underground gravitational flow.
   
The whole system is quipped with the control system of TV monitor (Windows XP operating system, PLC dynamic system, special Wincc configuration software), which can timely determine the filling slurry concentration and flow rate. The system adopts high-precision flowmeter and spiral scale, concentration meter to provide a global dynamic calculation and management, ensuring the dynamic high-precision mixture of filling materials.
