Light Weight Steel Q235 300TPH LECA Production Line

Expanded clay (LECA) is a lightweight aggregate manufactured from naturally occurring clay. It is non-toxic, disease free, chemically inert and has a neutral pH. It is used for a variety of applications including; a construction aggregate in lightweight concrete castings, floors and panels and as a loose lightweight fill. It is also used extensively in Green Roof systems as an additive to hydroponic systems as an eco friendly Horticultural Media.

Leca is initial letters for: Light Expanded Clay Aggregate.

Leca consists of small, lightweight, bloated particles of burnt clay. The thousands of small, air-filled cavities give Leca its strength and thermal insulation properties.

The base material is plastic clay which is extensively pretreated and then heated and expanded in a rotary kiln. Finally, the product is burned at 1100 °C-1250°C to form the finished Leca product.

Materials used for produce LECA:

Clay

Fly ash

Shale stone

Sewage sludge

Hengyang Industry specialized in produce, install and export LECA plant over 40 years, and build various leca plant in oversea countries. Production process is a little different upon various materials.

Rotary Kiln Dimensions:

Capacity: 0.5-300t/h

Calcination Temp: 400°C--1650°C

Diameter: 800mm-6000mm

Length: 12000mm—130 000mm

Power: According to the dryer and its capacity.

Material: Q235, G20, 310S, 253MA, 309S, Q245, etc.

This machine is much more important in leca production, all materials chemical reaction during higher temp calcination.
