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.

A 12 t/h pig manure organic fertilizer pellet production line supplied by RICHI Machinery has reached completion and entered trial operation at a swine farming complex in the state of Mato Grosso.

Brazil’s pig farming sector generates enormous volumes of manure, and regulatory pressure around waste management has been pushing operators toward granulation rather than simple land application — granulated fertilizer is easier to transport, store, and sell to crop farms in other regions.

The process here begins with anaerobic digestion residue (the buyer already had a biogas system in place), which arrives at the granulation line at around 60% moisture. RICHI’s scope was the downstream granulation: drum granulator, rotary dryer, cooler, and a rotary drum screener that separates finished pellets from oversized clumps that get returned to the granulator.

Final pellet size is 2-4mm, formulated with the buyer’s own organic carbon additives blended in at the mixing stage before granulation — RICHI didn’t supply the additive formula, just the equipment that handles the blended input consistently.

One challenge during commissioning: ambient humidity in Mato Grosso during the wet season is high enough that the dryer’s exhaust system needed a minor adjustment to the air-to-material ratio. RICHI’s commissioning engineer made the adjustment on-site over about two days of testing.

The plant is now producing roughly 9-10 t/h consistently during testing, with full 12 t/h rated capacity expected once the buyer finishes calibrating their own upstream digestate feed rate — RICHI’s portion of the equipment is performing at spec.

Installation work is currently in progress for a 2 t/h tofu cat litter production line at a facility outside Kuala Lumpur — RICHI’s technical team arrived on-site last week to begin equipment positioning.

Tofu cat litter manufacturing starts with soybean residue, specifically the byproduct (okara) from tofu/soy milk production facilities in the region. This is a material that’s sticky, high in residual moisture, and needs to go through a specific extrusion process rather than a standard pellet mill setup.

The line configuration: mixing system where the soybean fiber is blended with a small percentage of corn starch as binder, twin-screw extruder for shaping (this replaces the ring die pellet mill you’d see in a feed or biomass line), cutting mechanism, drying tunnel, and a final cooling/packaging conveyor.

One thing the buyer didn’t initially account for: the drying tunnel needs to be longer than what’s typical for feed pellets because tofu litter pellets need to retain a degree of porosity for clumping performance. RICHI’s engineers recommended extending the tunnel section by roughly 1.5 meters during the design review — a change that was approved before fabrication.

Electrical connections and the extruder mounting are the current focus this week. Trial production runs are expected within 10 days, pending final calibration of the extruder’s screw speed against the okara’s moisture content, which fluctuates batch to batch depending on the tofu factory’s process that day.

Manure-to-fertilizer conversion projects have been picking up across Eastern Europe, and the latest signing is a 10 t/h cow dung organic fertilizer pellet production line headed for a dairy operation cluster in Poland.

This isn’t a single-machine sale. The scope covers a horizontal mixer for blending dewatered cow manure with bulking agents (in this case, a mix of straw fines and a small percentage of NPK additive per the buyer’s soil testing results), a rotary drum granulator, a three-layer drum dryer, rotary cooler, and a screening/coating line for the finished organic fertilizer pellets.

Moisture management is the whole game with cow dung. Raw manure can sit at 70-80% water content depending on the dairy’s bedding and separation system. The buyer’s solids separator gets it down to roughly 55% before it enters RICHI’s line — still wet enough that the dryer has to do real work.

Pellet size target is 3-5mm for direct field application via standard fertilizer spreaders. The buyer’s agronomist specified an N-P-K blend ratio that varies seasonally, so the mixer’s dosing system needed to be flexible rather than fixed-ratio — something RICHI’s design team adjusted during the proposal stage after a few rounds of back-and-forth.

Equipment fabrication begins this month, with shipment targeted for early next quarter. Site visits for foundation inspection have been scheduled remotely via video walkthrough given the distance.

The 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.

A 4.5 t/h sawdust pellet production line has been ordered by a wood processing operator in Finland, with the contract finalized this week through RICHI Machinery’s European sales office.

The raw material here is mostly pine and spruce sawdust pulled directly from a nearby sawmill — moisture content runs 35-45% straight off the saw, which is why the line includes a drum dryer ahead of the ring die pellet mill. Skip that step and you’re looking at clogged dies within hours. We’ve seen it happen.

Pellet specification target is 6mm diameter, ash content under 0.7%, for the residential heating market. Finnish winters don’t forgive low-quality fuel pellets — too much fines and the auto-feed stoves jam.

Equipment scope includes a chain conveyor feeding system, drum dryer, hammer mill for secondary size reduction, the ring die pellet mill itself, counter-flow pellet cooler, and a vibrating screen for fines removal. Cooling matters more than people think for sawdust pellets specifically — pull them off the press too hot and they’ll crack during bagging.

Delivery is scheduled for late Q3. RICHI‘s engineering team has already sent the foundation drawings so the buyer’s contractor can begin site prep before the equipment arrives — saves weeks on the back end.
