Popis: Savinsk magnesite (lump and briquetted from the concentrate) can be thoroughly fired in rotary kilns of different sizes at a flame temperature of 1700–1750°C. The porosity of the powder is proportional to the size of the charge of raw material. During the firing of lump magnesite of all grades and briquette from ground concentrate it is possible to obtain powder with a porosity of 5–7%. When magnesite is being fired in a rotary kiln with a preparatory grid and when the raw materials charged amount to 1.5–2.0 times greater than when firing is done without the grid, a moderate-porosity powder is obtained. Thus, the fitting of a preparatory grid may increase the output of the furnace, and improve the quality of the product. During the firing of Savinsk lump and briquetted magnesite in rotary kilns in semiindustrial and industrial conditions, there is no bear formation, ringing, or crust formation on the lining of the furnace.
