Application of LECA Ceramic Particle
We also called eramisite as ceramic sand, which is a kind of ceramic particle product with high fracturing intensity, and lightweight aggregate. Ceramisite has excellent properties, such as low density, lightweight, fire prevention, earthquake prevention, high cylinder pressure,high porosity, tall softening coefficient, good frost resistance etc. So ceramisite is widely used in building materials, gardening, refractory insulation materials, Chemical, oil, and other departments.
Main Type of LECA Ceramic
1. Coal ash / Fly ash ceramisite
2. Clay ceramisite
3. Shale ceramisite
4. Sludge ceramsite
5. Petroleum proppant
How to Produce the LECA Ceramisite
The whole process is start from crushing, drying, mixing, grinding, granulating, drying, screening, calcining, cooling, packing
1. Crushing is to use the jaw crusher, roller crusher, impact crusher, fine crusher to crush the big size materials to the suitable size for grinding.
2. Sometimes we need a dryer to reduce the moisture in the raw material, which we can use rotary dryer or 3 drum dryer
3. Grinding the dried material out from the dryer, which we can use raymond mill or ball mill
4. Mixing the powder by suitable proportion, which we can use double shaft mixer
5. Use the granulator to make granules or balls, which we can use disc granulator, drum granulator, roller granulator.
6. If the granules are wet, it is better to dry by rotary dryer
7. Before calcine, the unqualified granules are screened out by the rotary drum screen,then
return back to the crusher to crush again for granulator:
8. Rotary kiln for calcine
9. Cooling granules by a rotary cooler
10. Packing the final products according to the client's needs.
