Dual-roller shredder machine
Stage 01 · Size Reduction

Dual-Roller Shredders

The first cut. Twin counter-rotating rollers pull in loose straw, round bales or agri-waste and reduce it to a manageable, uniform size before it ever reaches the hammer mill.

Feed TypeLoose straw, round bales, stalks
ThroughputUp to 12 TPH
DriveDual motor, independent rollers
BuildHardened-steel cutting teeth
Round-bale shredder machine
Stage 01 · Bulk Intake

Round-Bale Shredder

Purpose-built for farms that store residue in round bales. Feeds whole bales directly into the shredding chamber without manual breaking-down, cutting labour at the intake stage.

Feed TypeWhole round bales, up to 4 ft dia.
ThroughputUp to 12 TPH
LoadingHydraulic bale lifter compatible
BuildReinforced feed hopper
Pulse jet dust collection system
Stage 02 · Air Quality

Pulse Jet Dust Collection

Filters fine dust generated during shredding and grinding before it reaches the shop floor or open air — keeping the plant compliant and the working environment breathable.

Filter TypePulse-jet bag filter
Air VolumeSized to plant capacity
CleaningAutomatic reverse-pulse cycle
ComplianceMeets emission norms
Hammer mill machine
Stage 03 · Fine Grinding

Hammer Mills

Swinging hammers reduce shredded biomass into a fine, consistent powder — the exact particle size a ring-die press needs to form a dense, durable pellet.

Size132-315 kW
ThroughputUp to 8 TPH
ScreenInterchangeable mesh sizes
Wear PartsReplaceable hammers & liners
Ring-die pellet mill machine
Stage 04 · Compression

Ring-Die Pellet Mill

The heart of the plant. Rollers press the fine powder through a hardened ring die under heat and pressure, binding it into dense, uniform pellets without added binders.

Pellet Mill Size560, 780, 850 mm dia.
CapacityUp to 4.5 TPH per line
DieHardened alloy, Stainless Steel replaceable
MotorHeavy-duty, continuous rated
Rotary dryer machine
Pre-Process · Moisture Control

Rotary Dryer

Brings high-moisture feedstock down to the 10–12% level a pellet mill needs, using a rotating drum and controlled heat for even, consistent drying.

Moisture InUp to 40%
Moisture Out10–12%
Heat SourceBiomass-fired or thermal
BuildRotating drum, insulated shell
Flash dryer machine
Alternate · Rapid Drying

Flash Dryer

For finer, faster-drying material. Hot air suspends and dries particles in seconds as they travel through the duct — a compact alternative to a rotary drum where space is tight.

Drying TimeSeconds, not minutes
Best ForFine, low-density material
FootprintCompact, vertical layout
PairingWorks with cyclone separator
Automatic feeder machine
Line Support · Feed Control

Automatic Feeder

Meters material into the hammer mill or pellet mill at a steady, controlled rate — preventing jams and keeping motor load consistent across long shifts.

ControlVariable-speed metering
HopperReinforced, high-capacity
IntegrationSyncs with mill load sensors
BuildWear-resistant liner
Twin screw feeder machine
Line Support · Precision Feed

Twin Screw Feeder

Two intermeshing screws deliver a precise, even flow of fine material into the pellet mill — critical for consistent pellet density on high-throughput lines.

ScrewsTwin, intermeshing
PrecisionConsistent volumetric feed
BuildHardened flighting
DriveVariable-frequency motor
Belt conveyor
Line Support · Material Transfer

Belt Conveyors

Moves material between every stage of the line — from intake to shredder, shredder to mill, mill to bagging — sized to your plant’s exact layout.

Belt TypeHeavy-duty rubber/PVC
InclineFlat & inclined options
LengthCustom per layout
DriveGeared motor with tensioner
