The issue of reusing the undersized material resulting from dolomite screening
Thread Content
For a magnesium metal enterprise, the dolomite is generally purchased in a particle size that meets the production requirements; upon arrival at the plant, it undergoes simple screening. The material passing through the sieve goes directly into the feed bin and then into the rotary kiln, while some of the material that does not pass through the sieve remains behind. My question is: how should this portion of the screened material be disposed of? Can it be reused, or must it be discarded? If it is to be used again, what methods should be adopted? Thank you! Thank you all for your answers; the issue is resolved. Following the principle of the happiness distance is a good approach! This post was last edited by hhxxbb on 2009-3-13 18:58]
It should be reused; magnesium can be extracted from dolomite, and the particle size can be increased using the pelletization method
It is very difficult to burn dolomite particles with significantly different sizes in the same furnace, as this can lead to uneven heating of the dolomite, failing to meet the requirements of production. So it can be reused; most of the material that passes through the sieve is done so because its particle size does not meet the requirements. It can be collected in sufficient quantities and burned all at once ； At this point, the parameters controlling the kiln also need to be adjusted accordingly. But most manufacturers use it for other purposes, such as in infrastructure projects like road construction.
It can also be used as a raw material in steelmaking! ~
