5,000-300,000 Cubic Meters Per Year LECA Production Line
Introductions:
Since 2005, we, ZK Corp had been involved in the ceramsite industry
and commit to the research and development of the equipment for
industrial solid waste disposal and for energy saving research, so
that solid waste can be treated with harmlessness, reduction and
resource reusing. Our LECA equipment have been widely used in
Chinese LECA manufactures and won the good reputation from
customers. We have begun the exported business since 2010 and
create the good economic benefit. We adopt the energy saved
technology and get the good efficiency.
Application of LECA
We also called eramisite as ceramic sand, which is a kind of
ceramic particle product with high fracturing intensity, and
lightweight aggregate. Ceramisite has excellent properties, such as
low density, lightweight, fire prevention, earthquake prevention,
high cylinder pressure,high porosity, tall softening coefficient,
good frost resistance etc. So ceramisite is widely used in building
materials, gardening, refractory insulation materials, Chemical,
oil, and other departments.
Main Type of LECA Ceramic
1. Coal ash / Fly ash ceramisite
2. Clay ceramisite
3. Shale ceramisite
4. Sludge ceramsite
5. Petroleum proppant
Production Process of the Leca Plant:
1. Raw Material Process. The main raw material is clay or slurry.
2. Mixing and Granulating. The material fall into a double roller
granulator to become 5-10mm sphere shape material.
3. Preheating and burning. The sphere shaper material enter into
the preheating kiln by chute.
4. Cooling. 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 processed by air cooler machine and
then sent to the bag filter for dedusting.
7. Final Product Screening and Packing. The Light Expanded Clay
Aggregate will be screened into the size of 5mm, 15mm and 25mm.
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.
