LECA takes clay or mild clay as raw material, by the processing of pelletizing, burning to be expanded in rotary kiln. LECA possess the character of lightweight, high strength, low water absorption, thermal insulation, frost resisting,anti-corrosion, etc. LECA is widely used in the field of roof slope, heat insulation concrete, waste water treatment, landscaping and soilless culture, etc.
LECA manufacturing technique
The brief description of the process of LECA manufacturing technique: raw material mixing-pelletizing- screening- rotary kiln burning -stack- finished LECA(packing).
