Abstract

The rotary kiln for heating and roasting kaoline by using resistance furnace includes kiln body, support wheels, feeding end, discharging end, feeding mechanism and driving mechanism formed from motor, reduction box, small gears and large gears. The described feeding end and discharging end are movably connected with two ends of roasting rotary kiln, its feeding mechanism is connected with feeding end, and it is characterized the resistance furnace is placed in the lower portion of kiln body, it also includes smoke-exhaust pipe, smoke dust recovering column and smoke-discharging system formedfrom chimney, one end of smoke exhaust pipe is fixedly connected with feeding end, and its another end is connected with smoke-dust recovering column, and between said recovering column and chimney aflue gate is connected.

Description

technical field [0001] The invention relates to a rotary kiln for calcining kaolin, in particular to a rotary kiln for calcining kaolin heated by a resistance furnace. Background technique [0002] For a long time, the major problem that has restricted the production of high-quality ultra-fine calcined kaolin in my country (that is, particle size ≤ 2 μm, content ≥ 90%, whiteness ≥ 90%) is that the existing kaolin calcination equipment and technology are not up to standard, and it is difficult to meet the production of high-quality ultra-fine Process requirements for calcined kaolin. Although the country has also invested a large amount of manpower and material resources for this purpose, and has carried out research and development for many years, it has not obtained satisfactory results. In order to produce high-quality ultrafine calcined kaolin, it is necessary to import calcined kaolin rotary kiln equipment and calcination technology from abroad. Alt...
