Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, the outfit of production tailing micro-powder of the present utility model comprises efficient flash drying machine, powder concentrator, vibrations energy-saving grinding mill, activated stirrer, and described powder concentrator comprises powder concentrator charging aperture, fine powder outlet, meal outlet and air outlet of powder concentrator; The discharging opening of described efficient flash drying machine is connected with powder concentrator charging aperture, and the fine powder outlet of described powder concentrator is connected with the charging aperture of activated stirrer; The meal outlet of described powder concentrator is connected with the charging aperture of vibrations energy-saving grinding mill, and the discharging opening of described vibrations energy-saving grinding mill is connected with powder concentrator charging aperture.
The raw material producing tailing micro-powder is generally industrial tailings wet feed, before entering powder concentrator, must ensure that the degree of drying of mine tailing reaches requirement, therefore first enter efficient flash drying machine to dry, mine tailing after oven dry is directly sent in powder concentrator and is carried out sorting, meet the requirements of tailing micro-powder and be admitted to activated stirrer by the outlet of the fine powder of powder concentrator, finished product can be formed after adding activator and be transported in warehouse for finished product and store.Activator can by the SiO in tailing micro-powder
2, Al
2o
3be converted into activated state Deng material by inert condition, be beneficial to tailing micro-powder and play its effectiveness better when the admixture as cement, concrete etc.
The underproof mine tailing coarse granule sub-elected in powder concentrator enters grinding processing in vibrations energy-saving grinding mill by the outlet of its meal, and the mine tailing after grinding processing sends sorting in powder concentrator again back to.The mode of this first sorting grinding again can reduce vibrations energy-saving grinding mill grinding amount, thus reduces its power consumption or improve mill output.Between above-mentioned each equipment, the conveying of tailing micro-powder preferably adopts air flume.Air flume is pneumatic transport equipment, and its structure is simple, transfer efficiency is high, is more suitable for the conveying of powder relative to common feeder equipment.
