The sintering of magnesite over the length of rotary kilns

Means of rational utilization of caustic magnesite dust

“…According to the data of [2], in firing of magnesite dust formation occurs over the whole length of the kiln and the cooler and is especially intense in the heating and carbonization zones, which make up more than 70% of the kiln length, and therefore the dust removed in the dust-collecting units is a mixture of raw, caustic, and dead-fired magnesite (periclase) and also intermediate materials between these basic varieties, Their ratio depends upon the form and quality of the material being fired and the type and dimensions of the kilns and dust-collecting units.…”
