Production technology
This production line affords production of high quality activated carbon.
Activated carbon production technology
-Fruit stone shells are fed to the crusher to be crumbled to the required size .
-then the resultant mass is conveyed to vibration sieve to remove size-off-grade fragments
-Size-off-grade fragments are sent to the re-crumbling .
-Homogeneous raw materials are conveyed to the magnetic separator, to remove metal shavings, resultant from crushing and crumbling.
-the raw materials are conveyed to the drying machine.The moisture is reduced from 40% to 4-5%. The drying is made using dry hot air
-Dried materials are conveyed to carbomization stoves feeding zone .
-Granules are placed in special pallets as layers (thickness of the layers is determined by technology) and fed into carbonization stoves. Then the primary burning off and carbonization of granules take place.
-Then aften some time period, determined by technology. the pallets with carbonized materials are taken from the stove
-Baked coal granules are conveyed to the crusher to be crumbled to technological size of the activated carbon.
-From the crusher the granule is conveyd to fine separation vibrating screen.
-Size-off-grade coal is sent to secondary crumbling
-From the vibrating screen the coal is fed to packing tables by the activation stove
-Near the activation stove the granules are placed into special pallets and fed to the activation stove.
- In the stove coal granules are activated with the steam..
- When technologically specified time period is over, the elevating machine takes pallets with activated carbon.
-If the manufacturing technology was deranged thus causing activated carbon to clink, the clinker should be sent back to the crusher .
-After secondary crumbling the activated carbon is sent to packing .
-the carbon gets cold and is conveyed to the packing section.
-In the packing section the coal is packed into sealed paper bags with bunching attachment of 5-10 kg
-Then the active carbon is sent to the finished products warehouse.
*Notes
For active carbon production various manufacturing technologies have been developed. The choice of technology depends on requirement to quality of the final product. Medicine active carbon and that used for air cleaning or water purification have different quality requirements. Manufacturing technologies differ in temperature and time activation modes and by supplementary raw materials, fed to the mixer .
