Description

technical field

[0001] The invention belongs to a calciner for inorganic non-metallic materials, in particular to a dynamic calciner for powder or granular inorganic non-metallic materials. Background technique

[0002] Dynamic calcining powder furnace refers to thermal equipment that heats powder materials in a moving state (turning, stirring or suspension state) by means of pneumatic, electric or mechanical force. This is a type of thermal equipment that has long been recognized as an effective treatment of inorganic powder materials. At present, such equipment has been widely used in cement, power generation, chemical, refractory and other industries. Typical dynamic calcination equipment includes rotary kiln, fluidized calcination furnace, vertical multi-stage agitation calcination furnace, etc. Dynamic calcination equipment solves the problem of material temperature uniformity, and at the same time, it also shows excellent performance that static calcination equipment ...
