Lightweight Expanded Clay Aggregate Production Line LECA Plant

Kaolin, or ‘china clay’ as it is commonly called, is a hydrated aluminum silicate crystalline mineral formed over many millions of years by the hydrothermal decomposition of granite rocks. Hydrous kaolin is characterized by its fine particle size, plate-like or lamellar particle shape, and chemical inertness. Hengyang Industry is a manufactured by the calcination of kaolin to form an amorphous pozzolanic white mineral additive for use in cement-based products. Calcined Kaolin is an anhydrous aluminum silicate produced by heating ultrafine natural kaolin to high temperatures in a kiln. The calcination process increases whiteness and hardness, improves electrical properties, and alters the size and shape of the kaolin particles.

The term LECA, an acronym for “lightweight expanded clay aggregate,” is also a nickname for the popular semi hydroponic technique for growing house plants.

LECA is one of the best forms of soil-free growing. It functions on the principles of semi hydroponics, and more or less, puts soil-based home gardening techniques to shame.

What is light expanded clay aggregate (LECA Plant)?

light expanded clay aggregate or expanded clay aggregate (LECA or ECA), also called ceramic pellet, is one of the most popular lightweight aggregate made by sintering clay in a rotary kiln to about 1200°C.

Raw materials & applications: there are various types of lightweight expanded clay aggregate, and the main materials are the clay, shale, slate, coal powder, tailings, etc.

LECA is mainly applied in construction, interior decoration, agriculture, horticulture, gardening, playground, hydroponics, etc.

Light expanded clay aggregate (LECA Plant) Production Process and Main Machinery:

The production of the LECA generally requires seven steps: crushing, mixing, grinding, pelletizing, sintering, cooling and sieving.
