Mine is back to Cold Blast Whole system of screening. Cold back to mine the ore concentrate into specialized chutes, feeder by the disk will be returned to the ore unloading machine belt. More complex, equipment, and caused by high investment. But the finished sinter powder content of less powerful of the blast furnace, cold back to mine to participate in ingredients, can be stable sintering operation.
Working principle: gas in the cylinder spins, the role of ash in the centrifugal force, the particle size in accordance with sub-orbital motion, the inertia of ash after the loss of movement along the conical part of the lower cyclone exports slid.
High-temperature sintering flue gas requirements of the tail shell collector plate with insulation and heat-resistant concrete, for the dew-point temperature of flue gas temperature is higher than 20 ℃ or so, that is about 85 ℃.
Rocking back and forth 10 times to use each piece costs calculated for each screening-level quality of the composition of average particle size.
When the ingredients or feed than after the adjustments can not be adjusted by the kind of reaction, often in the sample second or third months to see the results after adjustment. |
