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 ADVANTAGES
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.
1. Energy-saving environment friendly:
Advanced production process and large capacity for single
production line with low heat loss. The advanced bag type dust
collector, which is equipped in LECA equipment, keeps exhaust gas
below 30mg/Nm3. The energ ysaving vertical preheater is equipped in
LECA production line with advanced process, and reasonable design
and high level technology.
2. High degree of automation: LECA production line is fitted with
temperature and pressure monitoring instrumentation, operating
parameters of the computer display, and is capable of using
advanced computer control to achieve automatic operation of the
entire system.
3. Lost investment: Based on the features of Light Expanded Clay
Aggregate (LECA), double-cylinder insert type rotary kiln controls
the preheating and calcination process.
