Lime Production Line
Active lime is mainly made of limestone, dolomite, chalk and other minerals with high calcium carbonate content, which are calcined at 1000-1100 °C.
Capacity: 200~1500TPD
Fuel: Coal gas, natural gas, and pulverized coal
Main Equipment: Rotary kiln / vertical lime kiln
AGICO CEMENT supplies different lime processing plant solutions for clients according to capacity, budget, kiln type and other elements.
The selection of the alime manufacturing process is determined by many factors: investment cost, lime activity requirements, fuel selection, raw material particle size, system capacity requirements, and environmental protection requirements. We will determine the production process according to the specific situation and requirements of customers.
From now on, we can provide six solutions for the lime calcination plant:

SOLUTION1: Lime Production Line With Rotary Kiln
Active lime is widely used in steel, alumina, metal magnesium, calcium carbide and power plant desulfurization paper industry. Active lime is an important auxiliary raw material for steelmaking. The use of active lime has a series of characteristics such as improving molten steel quality, increasing production, reducing steelmaking consumption and cost, and stabilizing operation. Practice has proved that all enterprises that use active lime to make steel have achieved significant economic benefits.
Investment Cost: The lime calcination plant with a lime rotary kiln as the main equipment has the widest applications, and require large investment and the wide occupied area.
Advantages Of Rotary Lime Kiln Production Line
Environmental Protection: the flue gas discharged from the vertical preheater at the kiln end has low temperature and low dust content, which makes the configuration of subsequent flue gas treatment simple and meets environmental protection requirements.
Lime Activity: the rotary kiln is open calcination, the structure of the kiln body is simple, the airflow is smooth, the sulfur-containing flue gas can be discharged in time, and the sulfur content in the fuel is not easy to adhere, so the finished product has low sulfur content and meets the requirements of steelmaking.
Energy-saving: the vertical preheater at the end of the kiln can make full use of the high-temperature flue gas generated by the calcination in the rotary kiln, which can not only greatly increase the output of the rotary kiln, but also fully reduce the heat consumption per unit product.
SOLUTION2: Lime Production Line With Vertical Kiln
The vertical lime kiln is suitable for small-capacity active lime production lines, low-cost, safe and environmentally friendly. The vertical lime kiln uses the principle that the material’s own weight descends and the hot gas rises for heat exchange to burn lime. We supply twin shaft lime kiln, double beam lime kiln, annular lime kiln and other vertical lime kilns
Advantages Of Vertical Lime Kiln Production Line
Advanced Technique: Compared with the rotary kiln, the limes production process of the shaft kiln is simple, the equipment moving parts are few, and the power consumption is low.
High Quality: The lime production line is set with jaw crusher , which can avoid the occurrence of raw burning and over burning due to excessive particle size difference, which not only stabilizes product quality, but also saves energy.
Energy Efficient: Compared with other limestone firing processes, it is more energy efficient. Apply for various types of area.
