LECA expanded clay aggregate  production line equipment

Brief introduction of Ceramsite: 

1.  Ceramsite is also called ceramic sand, is a kind of ceramic particle product with high fracturing intensity, belonging to lightweight aggregate family.
2.  Ceramsite has excellent properties, such as low density, high cylinder pressure,internal porosity, good frost resistance, shape and composition more homogeneous, and has a certain strength and robustness, which has light weight, shock resistance and good isolation features (Such as: heat insulation, sound insulation, moisture isolation) etc.  
3.  So ceramsite widely used in building materials, gardening, refractory insulation materials, Chemical, oil, and other departments. Ceramsite will be used more widely with the development of technology.

4.  The raw material for production ceramsite sand without special requirement, have many types, almost can be seen every where, such as: aluminum barium soil, clay, slate, sandstone and mudstone, shale, coal gangue, flyash, sludge can be given even industrial solid wastes as ceramsite proppant materials.

5.  Fuel. According to local fuel supply, using bituminous coal, crude oil or natural gas etc.

6.  Main Ceramsite Type:
1) Coal ash ceramsite
2) Clay ceramsite
3) Shale ceramsite
4)  Bauxite ceramsite(oil ceramsite) 

Producing Process Flow of Clay Ceramsite Production Line:

Crushing and Mixing ---- Granulating and Screening ---- Calcine and Cooling ---- Final Product Sieving
1) Crushing and Mixing:
First, Roll Crusher crush the raw material; then uniformly mix material by Double shaft Mixer.

2) Granulating and Screening:
Granulating by Double roller granulator.
Before calcine, reshaping and screening balls. the unqualified balls are screened out, then return back to the granulator for secondary granulating.
3) Calcine and Cooling:
Calcining the semi-product (wet ceramsite balls) by Rotary Kiln.
For the calcined balls' temperature is too high, need to cool by cooler. Then get the final product.
4) Final Product Sieving:
Sieving the final product according to its granularity.
