Slag recovery and treatment equipment is conducive to environmental protection. Slag is a part left over from the process of ore mining, which will affect the natural ecological environment without reasonable use. In order to deal with slag with zero pollution reasonably, dry discharge of slag is generally adopted? What are the slag recovery and treatment equipment?
There are many types of slag treatment equipment. The ore is grinded into very fine pulp. The ore powder less than 0.075mm generally accounts for 50% – 70%, and some are even finer. The pulp concentration is generally about 15% – 40%. To deal with the fineness in this range of slag,we choose the vertical roller mill.
〖Grinding filed〗：It aims at all kinds of non-metallic mineral materials with Mohs hardness less than 7 and humidity less than 6%. The grinding mill is widely used in electric power, metallurgy, cement, chemical industry, rubber, paint, ink, food, medicine and other production fields.
〖Performance characteristic〗:It integrates drying, grinding, grading and conveying. It has the characteristics of high grinding efficiency, low power consumption, large feed particle size, easy to adjust product fineness, simple equipment process, small floor area, low noise, small dust, simple operation and maintenance, low operation cost, less consumption of wear-resistant materials, etc.
The vertical roller mill as slag recovery and treatment equipment has the following advantages:
1. The particle size of the finished product is 22-180 μ m. With a production capacity of 5-200T / h, it is the mainstream equipment in the grinding industry;
2. The quality of the product is stable, the particle shape of the finished product is uniform, the particle size distribution is narrow and the fluidity is good;
3. Green environmental protection, energy saving and consumption reduction are products strongly advocated by the state;
4. High reliability, no need to seal the fan, further reduce the oxygen content in the mill, excellent explosion suppression performance;
5. Compared with ball mill, energy consumption is 40% – 50% lower; The production capacity of single machine is large, and low valley power can be used;
6. Convenient maintenance, low operating cost, no-load start-up, free of the trouble of starting up, low wear, special material for grinding roller and plate lining, long service life.
7. The maximum moisture content of the feed can reach 15%, and there is no need to equip another dryer;
8. The machine integrates crushing, drying, grinding, grading and conveying, with simple technological process, less system equipment and low comprehensive investment cost;
9. The machine adopts PLC automatic control system, and can realize remote control, simple operation and high degree of automation.
