Sludge Ceramsite Production Line Manufacturer Sludge LECA Ceramsite Production Line
Sludge LECA Ceramsite Production Line Product Description:
We are leading manufacturer of complete equipment for Light Expanded Clay Aggregate Production Line with capacity 15,000 to 300,000 m³/a. We can provide the whole service of design, equipment/spare parts supply, investment consultation, installation and operation training for LECA Plant.
When the raw material is clay or slurry, the production flow chart shall be consist of raw material process, mixing, granulating, insert type rotary kiln burning process, cooling process, screening and bag packing. When the raw material is shale, the production flow chart shall be consist of crushing, screening, single rotarykiln burning process, cooling process, screening and bag packing. The fuel could be coal, nature gas, biomass fuel and etc.
Production Process of the Sludge LECA Production Line:
1. Raw Material Process
The main raw material is clay or slurry. Building clay (or slurry) storage shell and flyash storage yard, we get the material by loader and do the proper mixing ration. And then the material will be fed into silo.When the clay size is too big, it should be crushed by roller crusher to get small size.
2. Mixing and Granulating
Set up an apron feeder under the hopper. Feed the material into a double shaft mixer. Then the material fall into a double roller granulator to become 5-10mm sphere shape material. And then they are fed to an insert type rotary kiln by belt conveyor.
3. Preheating and burning.
When the sphere shaper material enter into the preheating kiln by chute. The moisture will be dried and then the material will be fed into the burning kiln to become the Light Expanded Clay Aggregate (LECA) with bulk density of 500kg/m3.
4. Cooling
Light Expanded Clay Aggregate (LECA) outlet from the kiln will be fed into the cooler. Cooler shall adopt the single drum cooler, vertical cooler, grate cooler and etc.
5. Fuel Combustion
Coal, natural gas and biomass fuel are good choices as fuel.
6. Kiln Inlet Dust Collect
Gas from kiln inlet will be processed by air cooler machine and then sent to the bag filter for dedusting. And then it will be sent to the air.
7. Final Product Screening and Packing
The Light Expanded Clay Aggregate (LECA) outlet from rotary cooler and then fed into a vibration screen (or rotary screen). They will be screened into the size of 5mm, 15mm and 25mm. The different size will be packed in different bags, which will loaded for sales.
