A 2.5 t/h activated carbon pellet production line has departed for an industrial filtration media manufacturer located in the Gujarat region of India, with the shipment confirmed as loaded this week.
Activated carbon pelletizing sits a bit outside the usual biomass-and-feed conversation, but the core pelletizing technology shares similarities — what’s different is the raw material handling. The buyer’s process starts with powdered activated carbon (derived from coconut shell carbon in this case, which is widely available in the region given coconut shell charcoal production is already an established industry there).
The line includes a mixer where the activated carbon powder is blended with a binder — typically a small percentage of coal tar pitch or a similar binding agent, though the exact binder formula is the buyer’s own proprietary mix — followed by an extrusion-type pellet press rather than the ring die compression pelletizers used for biomass or feed. Activated carbon pellets are typically cylindrical extrudates rather than compressed pellets, and the die design reflects that.
After extrusion comes a drying stage (the binder needs to cure/dry without the carbon losing its porous structure — too aggressive drying can actually damage the activated carbon’s adsorption properties, which is the opposite problem from most pelletizing applications where you want fast, thorough drying).
Pellet diameter is 4mm, intended for water filtration cartridge applications — a growing market in India given increasing attention to water treatment infrastructure in both municipal and industrial sectors.
RICHI’s role in this project was primarily equipment supply with process guidance on the mechanical handling stages — the activated carbon activation process itself (the actual carbon production) was already established at the buyer’s facility; this line addresses only the pelletizing/shaping step downstream of that.
Shipping is expected to take approximately 3 weeks via sea freight to Mumbai port, followed by inland transport to the Gujarat facility.
