    Abstract

    Some problems of production technology of expanded clay aggregate in a rotary kiln are considered with the use of the method of dusting the particles of burning material with refractory, or highmelting, powders. A list of the main units of modernization for the rotary kiln is given. Dependence upon the consumption of dusting materials is shown, and the conditions of its usage in rotary kilns are investigated. Comparative technical indexes of operation during the industrial tests in modernized rotary kilns with the use of devices under discussion are offered. Industrial tests are given for four kinds of argillaceous raw materials.

    The use of the device to regulate the feeding of secondary air, which helps to reduce a fuel consumption at the expense of a decrease of heat loss by waste gases, is considered. The main technical and economic effects of using the devices under discussion in modernized rotary kilns are included.
