Abstract

A microcrystal material used for a cement kiln is disclosed, belonging to the technical field of inorganic nonmetal material processing. Raw materials include silicon carbide, silicon nitride, a material named as Chinese characters 'Ao sha' by the inventor, quartz, microcrystal powder and glass microbeads. The microcrystal material can change properties of a liner material of a cement kiln systemto avoid adhesion and reaction between the liner material and materials and to avoid firm crust, thus reducing faults of the cement kiln, increasing the service factor of the cement kiln, effectivelyenhancing cement kiln safety and saving the production cost.

Description

technical field [0001] The invention relates to an inorganic non-metallic material, in particular to a microcrystalline material, and belongs to the field of inorganic non-metallic material processing. Background technique [0002] Skinning in the cement kiln system is an unavoidable problem in the cement production industry when the new dry precalcining kiln process is adopted. Harmful ingredients such as alkali, chlorine, and sulfur in the raw materials in the cement clinker production process will be decomposed in the calcination area of ​​the kiln and become steam, which will be brought to the low-temperature area of ​​the preheater by the flue gas to condense on the surface of the material particles and return to the calcination system. This process is called cyclic enrichment of harmful components. Harmful components in the kiln tail preheater of the cement kiln will combine with the material after condensation and precipitation to form a crust containing a low-temper...
