In cement industry professional production equipment, according to different customers' requirements, the rotary kiln is divided into different types and the production quality and production process have the corresponding changes. Different models of rotary kiln equipment can produce different quality of materials, and so, on the choice of rotary kiln, adjust measures to local conditions, according to different needs to choose the appropriate rotary kiln equipment. Henan Zhengzhou Mining Machinery Co., Ltd. as the rotary kiln production manufacturer explains the characteristics of different types of rotary kiln equipment for everybody.

(1)  Straight type: straight cylinder, cylinder kiln head and preheater kiln body diameter is consistent. The production and installation of this type of kiln is convenient, and the kiln is consistent with the material filling coefficient, and velocity is uniform.

(2)  The kiln outlet expansion type: This space of the combustion is in expansion.This type of kiln can increase the heating capacity of kiln and improve the production.

(3)  Inlet expansion type: this kiln can increase the preheating capacity and reduce the speed of the wind preheater and exhaust temperatures, which saves energy consumption. In the same heat transfer zone of the kiln conditions, when the kiln inlet is enlarged, the length of the kiln can be shortened.

In a word, rotary kiln has a large capacity, high degree of mechanization with simple maintenance; high activity calcined white and low combustion.  So we can choose the method of silicon thermal magnesium smelting kiln to calcine dolomite.
