Equipment for limestone processing

Lime is made of limestone, dolomite, chalk, shells and other high calcium carbonate content of raw materials,by 900 ~ 1100 ℃ calcined. Lime is the earliest application of human cement material.
The original lime production process is the limestone and fuel (wood) layered laying, firing a week that is. Modern is the usage of mechanized, semi-mechanized shaft kiln and rotary kiln, boiling furnace and other equipment for production. Calcination time is correspondingly shortened, production of lime with rotary kiln only 2 to 4 hours, than the use of shaft kiln production can improve the production efficiency of more than 5 times in recent years, there have been cross-flow, double slope and oil ring kiln and kiln with preheater short rotary kiln and other energy-saving effect of significant technology and equipment, fuel is also expanded to coal, coke, heavy oil or liquefied gas.
The lime calcination process is the most important process in the lime production process, and the lime rotary kiln is the core equipment in the lime calcination process for calcining limestone or other raw materials such as dolomite into lime. ZK production of lime rotary kiln with high output, good product quality, mechanization, the advantages of high degree of automation for the majority of lime plant selection.
ZK mine machinery production of lime firing equipment - lime rotary kiln has a unique advantage:
(1) Advanced structure, and can be combined with low pressure loss of the vertical preheater effectively improve the preheating effect, the preheated limestone into the kiln decomposition rate of up to 20-25%, and can be directly used 10-15mm fine limestone;
(2) The use of three-dimensional design and simulation, optimization of the main components of structural design, the whole set of equipment more cost-effective;
(3) The use of excellent performance materials and processing technology to ensure smooth operation, the use of reliable;
(4) Rotary kiln at both ends of the use of a reliable combination of scales sealed, greatly reducing the air leakage;
(5) Easy maintenance operation, and greatly reduce the amount of maintenance.
