Can Tailings Be Used As Building Materials?
Tailings are the remaining waste after mineral processing or mineral extraction, which will cause certain harm to the environment. After being processed into fine powder by tailings mill, the tailings can be used as building materials and applied in construction, road construction and other projects.
Tailings powder production process
The tailings powder process generally use the dry milling process. The tailings generally have finer particles and can be ground into powder with a fineness of 22-180μm by a tailings mill without being crushed.
Phase 1: Feeding
The tailings are conveyed by the elevator to the storage hopper, and the storage hopper discharges the material and then feeds the tailings mill evenly by the feeder.
Phase 2: Grinding
As the tailings enter the mill, the qualified products after grinding are screened out by the screening system to screen out the fine powder of the tailings particle size, and then enter the collector through the pipeline. Qualified powder falls into the HLM vertical mill for re-grinding.
Phase 3: Collection
The tailings powder enters the pulse dust collector through the ventilation duct connected to the pulverizer, and the tailings powder enters the powder collector for packaging. The air after pulse dust collection and purification flows into the blower through the residual air duct above the dust collector. The air path is circulating. Except for the positive pressure from the blower to the grinding chamber, the air flow in the rest of the pipeline flows under negative pressure, and the indoor sanitary conditions better.
