Compact Plastic Granulator · Sprue & Runner Crusher for In-House
Regrind
Petite machine concasseur pour recyclage des déchets plastiques
A compact plastic crusher and in-house regrind machine built for
runners, sprues, reject parts, trim, and small rigid plastic scrap generated at injection molding,
blow molding, and extrusion lines. Delivers screen-controlled regrind output (reference: 50–150
kg/h)
with enclosed, low-noise operation and flexible voltage configuration — a practical, low-investment
path to closed-loop scrap recovery on the shop floor.
Pourquoi ce petit broyeur fonctionne pour le regrind interne en plastique
This machine is aimed at plants that need fast scrap recovery,
controlled particle size, and a footprint that fits beside molding or extrusion equipment instead of
inside a full central crushing room.
Compact Footprint for Shop-Floor Installation
The crusher is sized for in-plant use, making it easier to place beside injection molding, blow
molding, or extrusion machines where scrap is generated continuously.
Contrôle du bruit en enceinte fermée
The enclosed body helps reduce operating noise and keeps material splash better contained around
the cutting chamber.
Taille de regrind contrôlée par écran
Interchangeable screens let the plant match particle size to blending, conveying, feeding, or
direct in-house reuse requirements.
Kit de couteaux SKD-11 pour usage industriel régulier
The reference configuration uses SKD-11 knives, helping the machine maintain stable cutting
performance on rigid sprues, runners, and reject parts over longer operating cycles.
Configuration de puissance et d'écran flexible
Voltage, frequency, phase, and screen size can be adjusted to fit different plant standards,
resin types, and reuse targets instead of forcing a one-spec machine into every workshop.
Supporte la récupération en boucle fermée des déchets
By reducing scrap immediately into reusable regrind, the machine helps plants cut disposal cost
and return more plastic to internal production.
Matériaux typiques et utilisations des usines
This compact crusher is best matched to in-house recovery of rigid
plastic scrap that does not require the volume reduction or throughput of a larger central crushing
system.
Injection Runners and Sprues
A common fit for molding runners, sprues, startup scrap, and
short-shot parts that need immediate recycling beside the press.
Rigid Reject Parts
Suitable for small molded housings, covers, thick-wall rejects,
and similar rigid plastic components.
Extrusion Trim and Edge Waste
Useful for profile offcuts, sheet trim, and startup scrap when
the line needs quick size reduction and re-feed.
Blow Molding Trims
A practical option for smaller bottle and hollow-part trimming
waste where a large wet bottle crusher would be excessive.
Cell-Level Recycling Stations
Works well in decentralized recycling cells where each workshop
or line wants its own compact scrap-reduction machine.
Internal Regrind Loops
Helps operators recover regrind for blending, conveying, or
transfer to a larger downstream recycling route.
How the Small Crusher Machine Works
The workflow is simple: feed, crush, screen, and collect. The value
comes from stable regrind size and easy integration into daily plant scrap handling.
Alimenter les déchets
Runners, reject parts, or trim enter the hopper directly
from the molding or extrusion process.
Couper avec le rotor et les lames fixes
The rotor works against the fixed knife set to reduce the
incoming plastic into smaller particles suitable for screening.
Contrôler la sortie avec le criblage
Only particles that meet the target aperture pass through,
giving the plant more consistent regrind size.
Collecter le regrind pour réutilisation
Finished regrind can be collected for blending, conveying,
storage, or transfer to the next recycling stage.
Petit broyeur par rapport à un broyeur plus grand
The correct machine depends on whether the project is an in-house
scrap loop, a sheet and tray crushing job, or a combined shred-and-granulate workflow.
| Facteur de décision | Petite machine de concassage | Broyeur horizontal pour plateaux en plastique et feuilles de PVC | Broyeur-granulateur intégré |
|---|---|---|---|
| Meilleure adaptation | In-plant recovery of small rigid scrap and molded rejects |
Longues lattes, feuilles et larges déchets rigides | Matériaux volumineux nécessitant un broyage avant granulation |
| Empreinte | Compact et adapté au atelier | Machine plus grande pour des formes de matériaux plus larges | Système combiné plus grand et plus complexe |
| Forme matérielle | Sprues, runners, pièces rejetées, trims | Déchets rigides plats, larges et continus | Gros morceaux, pièces volumineuses et matières premières difficiles |
| Contrôle de sortie | Screen-controlled regrind for internal reuse |
Écaillés contrôlés par le criblage à partir de grandes pièces de déchets | Granulation après une phase de broyage primaire |
| Gamme de débit | ~50–150 kg/h reference (resin & screen dependent) |
Plus grand débit pour un large déchiquetage continu de feuilles | Réduction volumique avant l'étape de granulation |
| Matériau du couteau | Acier à outils SKD-11 pour une durée de vie accrue des lames | D2 ou SKD-11 selon le modèle | Acier allié de grande résistance pour les charges de déchiquetage primaire |
| Niveau de bruit | Carrosserie fermée pour réduire le bruit d'exploitation | Bruit plus élevé avec un design de chambre ouverte plus large | Le plus élevé — système à deux étapes avec bruit de déchiquetage |
| Quand choisir | When a plant needs a simple, compact scrap grinder beside production |
Quand la largeur et la géométrie du matériau dépassent la commodité du concasseur de petite taille | Quand le matière première est trop volumineuse ou difficile à introduire directement dans un petit concasseur |

Questions frequentes
These are the practical questions buyers usually ask before choosing a
compact scrap crusher for in-house plastic recycling.
It is mainly designed for rigid plastic scrap such as runners, sprues, molded rejects, trim,
and small rigid components. Final suitability depends on resin type and part thickness.
Output size is controlled by the screen aperture. You should specify the target regrind size
and how the material will be reused or conveyed downstream.
Please confirm voltage, frequency, phase, available floor space, hopper access, discharge
collection method, and any plant noise-control requirements.
Choose this machine when the job is local in-plant scrap recovery with moderate feed size. If
the material is wider, bulkier, or more difficult to feed, a larger horizontal crusher or
shredder-granulator is usually the better route.
The installation should leave room for routine knife inspection, screen changes, and safe
cleaning around the cutting chamber and discharge area.
The reference throughput is roughly 50–150 kg/h for typical rigid plastic scrap such as
runners, sprues, and small reject parts. The actual rate depends on resin type, part
thickness, screen aperture, and feed consistency. Please share your material details so we
can give a more accurate estimate.
Yes. The compact footprint and direct hopper feeding make it well suited for placement beside
a molding press as a dedicated sprue and runner crusher. The enclosed body also helps manage
noise in a production environment.
Knife service life depends on resin type, feed hardness, and operating hours. SKD-11 knives
offer extended durability for routine industrial duty. Many plants inspect knives
periodically
and rotate or replace them based on edge condition rather than a fixed interval. We can
advise on a maintenance schedule based on your specific material and throughput.
