Introduction
Henan Zhengzhou Mining Machinery Co.,Ltd has started the Light Expanded Clay Aggregate (LECA) equipment
manufacturing since company foundation. We always trance the new
technology developing on the LECA equipment manufacturing and have
cooperate with the college and R&D institute to improve the
equipment performance and function. 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.

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.
