Properties of sintered magnesite powders

Means of rational utilization of caustic magnesite dust

“…On the basis of this it may be assumed that with repeated circulation in the kiln-dust collecting unit system the magnesite dust in the final analysis is recovered, fired, added to the composition of the fired magnesite powder, and utilized, Detailed data on the properties of sintered magnesite powders from natural raw magnesite and mixtures of it with caustic dust and also of caustic unbriquetted and briquetted dust without and with additions is presented in [4]. This data is supplemented by similar information in [5,6], in which the significant contamination of the dust from the Cottrell filters with sulfur and other harmful impurities and as the result the low suitability of this dust for firing into powder is confirmed.…”
