RICHI Machinery has signed a contract for a 5 t/h RDF (Refuse Derived Fuel) pellet production line destined for a waste management facility in northern Italy, part of a broader push by the region to divert processed municipal solid waste from landfills toward cement kiln co-firing.
RDF pelletizing is messy work, frankly. The feedstock — pre-shredded and sorted municipal waste, mostly paper, plastic film, and textile fractions after metals and glass removal — is inconsistent by nature. No two loads are identical.
The line design accounts for this with a heavy-duty shredder/refiner stage ahead of the pellet press, plus a flat die pellet mill rather than ring die — flat dies handle the abrasive, variable-density RDF feedstock with less wear concentration in our experience, though throughput is somewhat lower per unit of installed power compared to clean biomass.
Pellet diameter target is 10mm, density specification set by the cement plant’s burner requirements rather than any standard pellet quality scheme — RDF pellets for kiln fuel don’t need to meet residential heating standards, just consistent calorific value and a size that flows through the kiln’s feed system without bridging.
No dryer is included in this scope; the buyer’s sorting line already controls moisture to an acceptable range before the material reaches RICHI’s equipment.
Manufacturing is scheduled to begin within two weeks. Given the contract includes a performance guarantee clause around throughput under variable feedstock conditions, RICHI’s team has requested feedstock samples be shipped ahead of fabrication for die calibration testing — a step that adds roughly three weeks to the timeline but reduces commissioning risk substantially.
