Analysis of the movement of magnesite in a rotary kiln

Conclusions

A radioisotope-assisted investigation of the rate of travel of magnesite in a rotary kiln yielded the boundaries of the technological zones of the kiln and the passage time of the material through these zones in the calcination process. The friability and hence the travel rate in the individual kiln sections vary considerably with the physico-chemical properties and grain size distribution of the magnesite.

Experimental data yielded the correction factor of friability which takes into account the changes in the physical state and friability of the magnesite in the course of calcining and can be used for a sufficiently precise determination of the travel rate and stay time of the magnesite in given kiln sections and the stay time of the material in the kiln as a whole from the equation v=KπDinn tanϕ.
