Réglages pour protéger les lames de recyclage dans les broyeurs de plastiques abrasifs

In abrasive plastic streams—glass-filled regrind, mineral-filled compounds, or bales that carry sand and grit—blade wear is rarely “just a materials problem.” In a single-shaft shredder, setup choices decide whether knives stay in steady cutting or spend their life heating, rubbing, and reverse-cycling. You control more levers than most plants document: feed rate uniformity, the speed/torque […]

Les lames de broyeur concaves améliorent le débit et réduisent les kWh par tonne

Concave shredder blades change the first contact between material and rotor in a single-shaft shredder. Instead of presenting a mostly flat edge that relies heavily on pusher force and friction to initiate a cut, a concave edge tends to create a more “hooking” engagement that encourages bite and controlled self-feeding. In the field, energy-per-ton and throughput gains […]

Réglage pas à pas du jeu des lames de broyeur entre rotor et stator

Shredder blade clearance (the gap between the rotor knives and the fixed bed/stator knife) is one of those settings that quietly controls everything you care about on a single-shaft shredder: cut quality and output size, throughput, energy draw, and how long your knives survive before they chip, roll, or start “polishing” instead of cutting. Set […]

Lames de rechange pour broyeur conçues pour une taille de sortie stable

Stable output size isn’t a “nice to have.” It’s what protects three things you feel every shift: throughput, energy, and downstream quality. When particle size drifts, screens load unevenly, amps climb, and the next step (wash line, air classification, granulation, pelletizing, or sorting) starts fighting variation instead of running steady. Replacement Shredder Blades change more […]

Ébrèchement des lames de broyeur mono-rotor : Guide de dépannage pour prévenir l'usure prématurée

Les arrêts imprévus dus à l'écaillage des lames sont rarement imputables à la malchance. Sur la plupart des broyeurs mono-arbre, l'écaillage des lames est un problème récurrent causé par un petit nombre de facteurs maîtrisables : contamination de l'alimentation, jeu incorrect, mauvais serrage/couple de serrage, défaut d'alignement ou choix d'un matériau/traitement thermique de lame inadapté. Ce guide est destiné aux équipes de maintenance, de procédés et d'approvisionnement exploitant des broyeurs mono-arbre […]

Granulation de joncs vs. anneau d'eau : choisir selon le matériau et le TCO

Choosing between strand pelletising and water ring pelletising isn’t just a preference for “wet” or “dry” cutting. It changes what controls pellet quality, what fails first during a disruption, and where your real cost-per-tonne sits (wear parts, drying, changeovers, and scrap). In UK compounding and recycling—especially when you’re running high-fill, glass fibre, mineral-loaded, or high-recycled-content […]

Bonnes pratiques de remise en état des rotors de granulateurs pour lignes de joncs

Nombre de dents du couteau rotatif en fonction de la vitesse de ligne et de la longueur des granulés

Rotary cutter tooth count (how many knives/teeth are on the rotor) is one of the fastest levers you have for stabilising pellet length on a strand pelletiser — and it’s the cleanest way to stay within a realistic cutter RPM ceiling. Get it wrong and you’ll see it immediately: long/short variation, tails, more fines, and […]

Liste de contrôle de sécurité pour le changement du couteau rotatif des granulateurs

This checklist is for strand pelletisers (pull‑strand / strand-cut systems) — not underwater pelletising. If you’re looking for a strand pelletiser changeover sequence your team can run the same way every time, start here. Scope & responsibility (read first): This checklist is written for strand pelletisers and focuses on the rotary cutter / knife changeover. It does not replace your OEM manual, site risk assessment, […]

Donnez une seconde vie à vos machines anciennes avec des couteaux rotatifs personnalisés

Last updated: 2026-03-30 Safety & compliance note (UK): This article provides general best-practice guidance for rotary cutter replacements. It does not replace your site risk assessment, OEM documentation, or competent engineering judgement. Always verify guarding clearances, runout limits, and safe systems of work under PUWER before returning equipment to service. Disclosure: This article references MAXTOR METAL products […]
