Lightweight Expanded Clay Aggregate Production Line - China

price: contact company for price

Lightweight Expanded Clay production process are summarized


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 ~

170 0C

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
