Vertical lime kiln, just like its name, the shape is erect. It is used for calcination limestone. Due to has low energy consumption, less cover area, less investment, wide applicability fuel, and more advantages, the vertical lime kiln is also widely used in metallurgy, construction materials, calcium carbide, Nanometer calcium carbonate, aerated concrete, sugaring, etc.
Applicable fuels are solid fuels such as coke and anthracite etc..
Application: such as metallurgy, building materials, calcium carbide, nano-calcium carbonate, aerated concrete, and sugar making.
This kiln is flexible in operation and can be adjusted within 60-100%, all can achieve the stable operation.
Applicable fuels are solid fuels such as coke and anthracite etc..
Low heat consumption, reasonable usage of heat energy.
The vertical kiln adopts micro-negative pressure operation (the top of the kiln), so that the air flow in the kiln is evenly distributed which is conductive to the limestone calcination.
