0086-138 3838 9622The rice husk pellet line RICHI Machinery shipped to the Mekong Delta region back in March has now completed commissioning and is operating at roughly 3 tons per hour during daytime shifts.
Rice husk is one of those materials that looks easy on paper and isn’t. Low bulk density, high silica content (which chews through wear parts faster than wood), and almost zero natural binder. The pellet mill here runs a specialized die with a compression ratio suited for husk — a standard wood-pellet die would wear out in weeks.
Output goes to a regional ceramics factory as boiler fuel, replacing a portion of their coal consumption. Pellet diameter is 8mm, which the buyer specifically requested for their stoker-fed boiler — smaller diameters were tested and caused feed inconsistency.
No dryer was needed for this setup. Rice husk arrives at 9-11% moisture from the mills already, which sits right in the sweet spot.
The buyer’s operations manager mentioned during commissioning that die replacement intervals will be the thing to watch over the next six months — RICHI has already arranged a spare die shipment to be held locally rather than shipped from China each time, cutting downtime risk considerably.
