It has the plasticity, viscosity, scattering, sintering tendency,
flame rtardancy, fre resistance, adsorptivity, weather ability
and chemical stability.
 Use:
To calcine and whitening of kaolin, and also can be used
to calcine the inorganic nonmetal materials.
Feature:
 The
performance is good. The temperature distributing is even
and stable during calcining, and heat using rate is high.
It is easy to control. The quality of products is uniform.
The
investment is little, the construction of calciner is simple
and compacted. The construction period is short and the life
of calciner is long, the floor area is small. It is easy to
maintain.
The
consumption of energy, power and fuel is little (0.12-0.2
tons of coke can produce 1 tons of product).
