This paper introduces the methods of industrialized production of lime and main equipment of new type of shaft kiln and preheater with vertical preheater and cooler lime rotary kiln firing technology and equipment. From the thermal properties and its effect on the dynamics of burnt lime Angle are analyzed; From the perspective of technology, this paper analyzes the various lime calcining technology characteristics of the technology and equipment. By review analysis the domestic main lime calcining technology and equipment of the operation of the practice, to evaluate the various lime calcining technology and equipment to provide the reference and predicted with the new type of rotary kiln burning lime into the continuous development of technology and equipment, lime production line capacity is large, new lime rotary kiln firing technology will get rapid development.
