Product Introduction
The functions of the two kiln chambers for calcination and heat storage are interchangeable and operate alternately. That means, when one kiln chamber is calcining, the other kiln chamber accumulates heat and exchanges once every 12 to 15 minutes. The double-chamber shaft kiln can produce high-quality lime products due to its reasonable thermal characteristics of calcined lime.
Since the combustion adopts the principle of regenerative technology, its energy consumption index is the lowest among all kiln types. The parallel flow regenerative active double-chamber shaft kiln has a high level of automation, which can ensure the long-term safe, stable and efficient operation of the lime kiln and reduce operating labor costs.
Product Advantages
01.
High production efficiency: It can achieve continuous feeding and discharge, so the production capacity is higher than that of a single-chamber lime kiln;
02.
High energy utilization: Twin shaft lime kiln is usually designed to be more energy-saving. Through effective heat exchange systems, it can make full use of heat and reduce energy waste;
03.
Good flexibility: Twin shaft lime kiln is suitable for a variety of raw materials and process requirements, which increases its flexibility in different industrial applications. Can adapt to raw materials of different particle sizes, humidity and chemical composition;
04.
Uniform heat supply: 2×33 burners are evenly distributed inside the kiln chamber. Each burner provides heat to the same range of the kiln chamber space, so that the heat supply on the kiln chamber section is uniform, which is beneficial to the uniform and stable roasting of the product;
05.
Environmental protection: Compared with traditional lime kilns, double-chamber lime kilns are generally more environmentally friendly. It can effectively control exhaust emissions and reduce negative impacts on the environment.
Application Scope
Suitable for metallurgy, building materials, chemical, environmental protection and other related industry.
