Advanced Design Fly Ash Leca Production Line Plant Supplier
Introduction of LECA Production Line
Light Expanded Clay Aggregate Production Line: When the raw material is clay or slurry, the production flow chart
shall be consist of raw material process, mixing, granulating,
insert type rotary kiln burning process, cooling process, screening
and bag packing; When the raw material is shale, the production
flow chart shall be consist of crushing, screening, single rotary
kiln burning process, cooling process, screening and bag packing.
The fuel could be coal, nature gas, biomass fuel and etc.
Production Process of the Leca Plant:
1. Raw Material Process
The main raw material is clay or slurry. Building clay (or slurry)
storage shell and flyash storage yard, we get the material by
loader and do the proper mixing ration. And then the material will
be fed into silo.When the clay size is too big, it should be
crushed by roller crusher to get small size.
2. Mixing and Granulating
Set up an apron feeder under the hopper. Feed the material into a
double shaft mixer. Then the material fall into a double roller
granulator to become 5-10mm sphere shape material. And then they
are fed to an insert type rotary kiln by belt conveyor.
3. Preheating and burning.
When the sphere shaper material enter into the preheating kiln by
chute. The moisture will be dried and then the material will be fed
into the burning kiln to become the Light Expanded Clay Aggregate
(LECA) with bulk density of 500kg/m3.
4. Cooling
Light Expanded Clay Aggregate (LECA) outlet from the kiln will be
fed into the cooler. Cooler shall adopt the single drum cooler,
vertical cooler, grate cooler and etc.
5. Fuel Combustion
Coal, natural gas and biomass fuel are good choices as fuel.
6. Kiln Inlet Dust Collect
Gas from kiln inlet will be processed by air cooler machine and
then sent to the bag filter for dedusting. And then it will be sent
to the air.
7. Final Product Screening and Packing.
The Light Expanded Clay Aggregate (LECA) outlet from rotary cooler
and then fed into a vibration screen (or rotary screen). They will
be screened into the size of 5mm, 15mm and 25mm. The different size
will be packed in different bags, which will loaded for sales.

Main Equipment - LECA Rotary kiln
LECA (Light Expanded Clay Aggregate) as a new environmental protection material is widely used in the
construction field. It can be made of wallboard, brick and other
new wallboard material. It also can be used for insulation, floor,
lightweight concrete, water treatment and etc. Rotary kiln is the
key equipment in the LECA production. The performance will affect
the final LECA quality and production cost directly.
OUR ADVANTAGE of LECA Rotary kiln
1. Rotary kiln drive adopts frequency conversion speed adjustment.
High efficient and low power consumption.
2. Low unit product fuel energy consumption.
3. Minus pressure operation and low powder dust pollution;
4. Simple process flow chart. Complete drying, granulating, burning
simultaneously.
5. Compact layout, light system equipment weight and low
investment.
