Refractory bricks used in rotary lime kilns must meet these challenges as well as help conserve energy. Minimizing heat losses through the kiln shell can help lime producers achieve production efficiencies that are essential in todays competitive markets. Heat loss through the kiln shell is of growing concern to lime kiln operators.
Rotary lime kilns typically have four refractory zones with varying types of refractory. Long process kilns require abrasion resistant, high strength alumina brick for the charging zone. The charging zone is where the abrasion of the stone can be particularly severe.

Rotary kilns consist of a rotating cylinder inclined at an angle of 3 to 4 degrees to the horizontal. Limestone, chalk or Dolomite is fed into the upper back end, and fuel plus combustion air is fired into the lower front end.The product is then discharged from the kiln into a cooler, where it is used to pre-heat the combustion air.
Star Trace Bauxite Rotary Kiln can be used in a wide range of fields, such as dolomite, kaolin, bauxite, refractories, cement, limestone, vanadium minerals, activated carbon, coke, mineral powder, alumina, magnesium oxide, zinc oxide, special cement, etc. Bauxite Rotary Kiln is the main equipment for dry and wet production of
Vertical preheater Vertical preheater is one of the main active lime equipment, the main effect of vertical preheater is the limestone material sent to the preheater, and use high temperature exhaust gas from the kiln calcining out emissions1150 degrees Celsius, the material in the preheater evenly heated to about 900 degrees Celsius.In the preheating process of 30CaCO3 is under preheater ...

In contrast to vertical kilns that operate fully charged, the rotary has 90 of its volume filled with flame and hot gases new surfaces of the stone are exposed as the kiln slowly rotates. As the area of solids exposed is small, this type of kiln has a lower efficiency than a vertical kiln. A rotary kiln utilized by W. S. Frey Company,
