Product Description
Kaolin, commonly known as 'china clay,' is a hydrated aluminum silicate crystalline mineral formed over millions of years through hydrothermal decomposition of granite rocks. Characterized by fine particle size, plate-like shape, and chemical inertness, hydrous kaolin serves as a key raw material for LECA production.
Hengyang Industry manufactures calcined kaolin through high-temperature kiln processing at approximately 1200°C, transforming it into an amorphous pozzolanic white mineral additive ideal for cement-based products and lightweight expanded clay aggregates.
Lightweight Expanded Clay Aggregate (LECA) Overview
LECA (Lightweight Expanded Clay Aggregate) represents an advanced semi-hydroponic growing medium that outperforms traditional soil-based gardening methods. This ceramic pellet aggregate is manufactured by sintering clay in rotary kilns at 1200°C temperatures.
Raw Materials & Applications
Various raw materials including clay, shale, slate, coal powder, and industrial tailings can be processed into lightweight expanded clay aggregates with diverse applications across multiple industries.
LECA Technical Specifications and Applications
| Grading (mm) | Density (kg/m³) | Applications |
|---|---|---|
| 0-4 | ≤710 | Lightweight concrete, bricks, prefabricated slabs, tiles, water purification, agriculture |
| 4-10 | ≤480 | Lightweight concrete, tiles, prefabricated slabs, aquaculture, noise barriers |
| 10-20 | ≤380 | Lightweight concrete, sewage systems, gardening, drainage systems |
| 0-25 | ≤430 | Floor decoration, light padding, road construction, aquaculture |
LECA Production Process and Equipment
The complete LECA manufacturing process involves seven sequential stages, each requiring specialized industrial equipment:
