Sistema Integrado de Reduccion

Maquina Integrada Trituradora y Granuladora para Residuos Plasticos Voluminosos

Una maquina integrada trituradora-granuladora combina la trituracion primaria a baja velocidad y la granulacion final a alta velocidad en un solo chasis compacto. Procesa residuos plasticos voluminosos, gruesos e irregulares — purgas, laminas gruesas, bidones, tubos, coladas de inyeccion — que no pueden alimentarse directamente en una granuladora independiente.

Integrated Shredder and Crusher Machine

Un Proceso Integrado de Tres Etapas

A standalone granulator requires pre-sized input. Feed it a purge lump, thick drum, or long pipe and it jams, overheats, or produces oversized rejects. The integrated shredder-crusher solves this by splitting the job into two coordinated stages inside one frame.

1

Reduccion en Dos Etapas

Los residuos voluminosos son reducidos primero por la trituradora de baja velocidad para evitar formacion de puentes, atascos y picos de carga.

2

Control Inteligente de Carga

El PLC equilibra las condiciones de alimentacion entre trituradora y granuladora para una salida continua y operacion segura.

3

Calibrado Final por Criba

El material pre-triturado cae directamente en la granuladora donde cribas intercambiables definen el tamano final — tipicamente 10, 20 o 30 mm.

4

Descarga Directa al Proceso Siguiente

El material calibrado sale por la criba y alimenta directamente la siguiente etapa — transportador, silo o extrusora.

Ventajas Clave del Diseno Integrado

The integrated design is chosen when floor space is limited, installation budgets are tight, or operators cannot manage two independent machines. Here is what the combo delivers that separate units do not.

Diseno Compacto

Combina dos procesos esenciales en un solo chasis. Ideal para plantas de reciclaje donde el espacio es limitado.

Flujo de Trabajo Simplificado

Elimina la transferencia entre trituradora y granuladora — sin transportador intermedio, sin tolva adicional, menos puntos de mantenimiento.

Automatizacion Inteligente

El PLC gestiona respuesta a sobrecargas, reversa automatica y coordinacion entre ambas etapas sin intervencion del operador.

Problems the Integrated Machine Solves

Most of these issues come from trying to feed bulky plastic directly into a standalone granulator, or from running a shredder and crusher as two disconnected machines with separate controls.

Problem

Granulators jam, overheat, or produce oversized rejects when fed purge lumps, thick drums, or long pipes.

Rumtoo Solution

The integrated low-speed shredder pre-reduces bulky input to 40–80 mm pieces the crusher can handle cleanly — no bridging, no motor stalling, no melting of soft plastics from high-speed friction.

Problem

A separate shredder + conveyor + crusher setup takes too much floor space and installation budget.

Rumtoo Solution

The integrated design eliminates the transfer conveyor and combines both stages in roughly 3–4 m² — over 65% less floor space than the separate setup, with fewer electrical connections and a single foundation.

Problem

Two separate machines with independent PLCs respond to overloads independently, causing feed surges and inconsistent output.

Rumtoo Solution

The single integrated PLC monitors both motor currents simultaneously. If the crusher approaches overload, it slows the shredder — producing steadier output and fewer manual interventions than two disconnected controllers.

Problem

High noise levels from the crusher make the workshop environment uncomfortable and require hearing protection.

Rumtoo Solution

The shredder stage operates at low speed (60–100 RPM) with minimal noise. The crusher is enclosed within the integrated frame, reducing overall noise compared to a standalone open-frame granulator processing the same material.

Equipment and Material Reference

The shredder breaks down bulky input into manageable pieces; the crusher below refines them to a controlled final particle size through a sizing screen.

Waste BOPP film before shredding

Feedstock View: bulky waste BOPP film before processing

The integrated shredder-crusher is designed for feedstock that cannot be fed directly into a standalone crusher — thick sheets, large containers, purge lumps, film bales, and other bulky rigid or semi-rigid plastic waste that needs primary size reduction before final granulation.

  • Handles irregularly shaped and oversized plastic waste
  • Low-speed shredder prevents jamming on thick and bulky feedstock
  • No manual pre-cutting required before feeding

Output View: shredded material ready for downstream processing

After passing through both the shredder and crusher stages, the output is a uniformly sized regrind controlled by the crusher screen. This consistent particle size feeds directly into washing lines, pelletizers, or extruders without additional sizing steps.

  • Crusher screen controls final particle size (10–30 mm typical)
  • Consistent regrind size improves downstream washing and extrusion stability
  • Ready for direct feeding to pelletizing, washing, or reprocessing

Wide Range of Applications

Designed for tough, bulky plastic materials that standard granulators cannot process efficiently on their own.

  • Purge Lumps

    Large compact masses from extrusion or compounding lines that are too dense and irregularly shaped for a standalone crusher.

  • Thick Sheets & Plates

    Thermoformed sheet scrap, offcuts, and heavy plate-like materials with wall thickness above 5–10 mm.

  • Drums & Barrels

    Rigid HDPE or PP containers that need primary breakdown before final granulation to controlled particle size.

  • Pipes & Profiles

    Long or hollow rigid PVC, PE, or PP sections that require staged size reduction to avoid crusher jamming.

  • Injection Runners & Sprues

    Heavy sprues and runner systems from injection molding operations that are too bulky for direct granulation.

  • Automotive & Large Molded Parts

    Bumpers, trims, housings, tanks, jerry cans, and other large blow-molded or injection-molded plastic scrap.

Output varies based on material density, wall thickness, and selected screen size. Contact Rumtoo with your material data for a confirmed capacity estimate.

Checklist Before RFQ

These inputs help Rumtoo recommend the right model and screen configuration for your application.

Feedstock Type and Dimensions

Describe the material — purge lumps, drums, pipes, sheets, runners, etc. Include approximate maximum dimensions and wall thickness.

Target Particle Size

State the final regrind size your downstream process requires — typically 10 mm, 20 mm, or 30 mm for pelletizing or washing lines.

Throughput Requirement

Provide the target kg/h and daily operating hours so the motor power and feed system are sized with adequate margin.

Downstream Process

Specify what comes after the shredder-crusher — washing line, pelletizer, extruder, or storage — so the discharge and regrind size are matched.
