Vertical Shaft Kiln Machinery for Sintering Limestone
Lime vertical 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.he vertical kiln was manufactured by ZK group with modern new technology, which is an environment protection, save energy, higher machanization and automaticity, quite modern lime kiln. Because it adopts the modern technology, make full use the cheap energy, especially pollution of gas for environment harmful( such as conventer gas, blast furnace gas, calcium carbide furnace tail gas) as the energy, turn waste into wealth. Thus will protect the environment, and produce the high quality lime with lowest cost. To use this new technology enterprise, economic benefits have increased significantly.
Application
It was widely used in metallurgy, construction materials, calcium carbide, Nanometer calcium carbonate, aerated concrete, sugaring, etc.

Working Principle
The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly around its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, the materials gradually move down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or 'firing pipe') which acts like a large burner. The fuel may be gas, oil or pulverized coal.
