LECA Production Line and Main Equipment
Processing Capacity: 1.9-76 tons/hour
The production of LECA generally requires 7 steps: crushing, mixing, grinding, granulating, sintering, cooling, and sieving.
The main equipment of the LECA production line includes a jaw crusher, mixer, ball mill, granulator, rotary dryer, drum screen, rotary kiln, and cooler.
1. Raw Material Process
The main raw material is clay or slurry. Building clay (or slurry) storage shells and flash storage yard, we get the material by loader and do the proper mixing ratio. And then the material will be fed into the silo. When the clay size is too big, it should be crushed by a roller crusher to get a 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 falls into a double roller granulator to become a 5-10mm sphere shape material. And then they are fed to an insert-type rotary kiln by a belt conveyor.
3. Preheating and burning
When the sphere shaper material enters 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 a 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 the kiln inlet will be processed by an 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 the 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 sizes will be packed in different bags, which will be loaded for sale.
Baichy is a leading manufacturer of complete sets of lightweight expanded clay aggregate production lines with a capacity of 15,000 to 300,000 cubic meters per year. We can provide full service of design, equipment/spare parts supply, investment consultation, installation, and operation training for the LECA factory.
When the raw material is clay or mud, the production flow chart should be composed of the raw material process, mixing, granulation, plug-in rotary kiln firing process, cooling process, screening, and bagging. When the raw material is shale, the production process consists of crushing, screening, single rotary kiln firing process, cooling process, screening, and bagging. The fuel can be coal, natural gas, biomass fuel, etc.
1. Energy-Saving Environment Friendly
Advanced production process and large capacity for a single production line with low heat loss. The advanced bag-type dust collector, which is equipped with LECA equipment, keeps exhaust gas below 30mg/Nm3.
2. High Degree of Automation
Leca production line is fitted with temperature and pressure monitoring instrumentation, and operating parameters of the computer display, and is capable of using advanced computer control to achieve automatic operation of the entire system.
3. Lost Investment
Based on the features of Light Expanded Clay Aggregate (LECA), a double-cylinder insert-type rotary kiln controls the preheating and calcination process. The energy-saving vertical preheater is equipped in the LECA production line with advanced processes, reasonable design, and high-level technology.
