Auxiliary Recycling Equipment
Automatic Knife Grinder
A precision blade sharpening machine for crusher, shredder, and chipper knives that helps keep cutting performance stable and maintenance cycles predictable.
Why This Knife Grinder Fits Recycling Workshops
The RT-1600 is designed for accurate resharpening, steady head travel, and workshop-friendly maintenance so blade quality stays consistent across repeated sharpening cycles.
0 to 90 Degree Chuck Adjustment
Its electromagnetic chuck holds blades securely while supporting different sharpening angles for varied blade geometries.
Stable Travel and Feed Control
Frequency-controlled head travel and precise feed adjustment support smooth grinding passes and repeatable results.
Up to 1600 Millimeter Blade Capacity
The standard model handles long industrial knives used on granulators, shredders, shears, and related cutting equipment.
Workshop-Oriented Durability
Rigid construction, low-vibration operation, and accessible wheel maintenance help extend service life in daily production use.
Machine Overview
Designed for Crusher and Shredder Blade Maintenance
Instead of replacing blades early, recyclers can restore edge quality in-house and reduce the downtime caused by worn knives, poor cutting, and inconsistent material size reduction.
Fits Preventive Maintenance Workflows
With adjustable head speed, controlled feed depth, and accurate positioning, the machine supports repeatable sharpening as part of planned maintenance rather than emergency repair.

Frequently Asked Questions
The RT-1600 can grind blades up to 1600 mm in length and 180 mm in width.
Yes. It is suitable for chipper knives, granulator blades, shear blades, and other comparable straight industrial knives.
Yes. Installation guidance, operator training, and commissioning support can be arranged according to project scope.
The standard warranty period is 12 months for covered parts and workmanship, with ongoing technical support available.
It depends on material and runtime, not a fixed calendar. Resharpen when cut size drifts, throughput drops, or the blade stops producing a clean cut. Abrasive or contaminated feed such as mineral-filled plastic, metal, or tire dulls edges faster than clean plastic, so high-wear lines regrind more often. Scheduling a regrind before the edge fully rounds over removes less material and extends total blade life.
Regrind as long as the blade still has usable steel above its minimum dimension and the body has no cracks or chips too deep to grind out. The RT-1600 restores the edge to 0.03 mm precision, so most knives can be sharpened many times before reaching their wear limit. Switch to replacement granulator blades only when the knife hits its minimum size, develops structural cracks, or loses its hardened layer.
