calcination industrial furnaces Lime and dolomite
The process of converting limestone and dolomite into a product, i.e. calcination, is chemically an endothermic reaction, and according to the characteristics of the raw materials, it takes place at a temperature higher than 900 degrees Celsius.

With the advancement of knowledge and industrial developments, major and structural changes have occurred in lime kilns.
Optimum design and correct use of experimental and laboratory data are the keys to the success of lime and dolomite calcination projects, and the choice of technology and type of kiln depends on various parameters, some of which are as follows:
- The quality and characteristics of raw materials in terms of chemistry, physics and mechanics
- Type and specifications of the desired product
- production capacity
- The type and characteristics of the fuel
- Optimum conditions for product size and crushing of raw materials
In general, existing industrial lime kilns can be placed in different types of categories. In the classification based on the flow of materials relative to combustion gases, the furnace can be Parallel Flow or Counter Flow.In another type of classification, furnaces are divided into positive pressure and negative pressure types.From another point of view and in the industry, lime and dolomite kilns are divided based on the cross-sectional shape of the materials or their mechanical performance:
Furnace and its type of technology are proposed in Betsaco's engineering departments after examining all project conditions and requirements and in order to achieve a cost balance with raw material and product specifications, the most suitable proposals are presented to the investors and based on the basic design, from the collection Domestic and foreign partners provide complete equipment and parts for all types of furnaces.
