Lightweight Expanded Clay Aggregate Production Line - Chinaprice: contact company for price
Using Illite structure clay as main raw material, mixed with
a small amount of sulfur iron slag, calcium carbonate powder
and heavy oil as additive and expansion agent, after
proportioning, mixing, homogenizing, adding water then
kneading and stirring in three biaxial mixer to make wet
clay mud pie which contains about 30% water, with the belt
conveyor is fed into the rotary kiln, in the kiln drying,
granulating, baking into lightweight expanded clay.
After wet clay mud pie entering into the kiln, it moves
forward with the rotation of rotary kiln, first contact with
the hot flue gas from weak to strong heat smoke, resulting
in strong heat exchange, evaporation drying and clay broken
into particles, by rotation makes the clay into balls .
Rotary drying kiln in special structure greatly increases
the heat transfer area of each section, level of winnowing
material, leads to comprehensive high heat exchange
efficiency, so which is extremely beneficial for the clay on
the evaporation of wet heat and mass transfer and drying
process . When the clay particles from the forepart drying
kiln pass into the posterior calcining kiln, dry granulation
has been completed.<
Calcining kiln is hollow kiln with firebrick lining for
winnowing device, which can effectively increase the
material lifting height, so that the cycle number of
materials in contact with hot smoke stream is increased and
achieve rapid warming, obtain enhanced heat exchange effect,
thereby accelerating the high temperature solid phase
reaction and rapid expansion of sintering process.
Ceramic sintering process temperature range as follows:
1. temperature of flue gas in feeding end of kiln is 150 ~
2. flue gas temperature in coupling region of drying kiln
and calcining kiln is 800-850 0C
3. Ceramic calcination temperature ( rapid expansion
temperature ) is 1120-1150 0C
