Making Plant Powder Production Line Advanced Portland Cement Industry Machine Active VSK Kiln
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.
Limestone and clay are the main ingredients employed in the
manufacture of Portland Cement. These materials are suitably
reduced in size and then ground to fine powder. This powder is
pneumatically homogenized and fed into a kiln to burn the at around
1450 Deg C. The product from Vertical kiln is known as Clinker.
There are two type of kilns employed for producing clinker; Rotary
kln and Vertical kiln. While rotary kiln is employed for large
scale production of clinker, the vertical kiln is used for small
scale production of clinker.
Good quality limestone with other additives ensures quality production of clinker. Clinker produced in Vertical kiln the has been found to be of excellent quality for producing Portland Cement, Pozzolona Portland Cement and Portland Slag Cement by grinding along with a small quantity of gypsum and other admistures.
Vertical Kiln consists of a round, vertical pipe lined with refractory bricks. A feed arrangemnt at top feeds nodulized raw meal into the kiln at a uniform rate. Burned clinker is extracted at the bottom through a slowly rotating conical grate, which also distributes combustion air into the kiln.
The output (clinker) passes through a gate which do not allow false air entry into the kiln.
The temperature of the clinker discharged varies between 80 to 90 Deg C and conveyed to a storage yard.
