Product catalog summary
Overview: This document provides detailed technical specifications and features of WEIMA's single-shaft shredders, including models WL 600, WL 4-8, WLK 4, and WLK 800. These shredders are designed for precise cutting with high throughput, utilizing a profiled V rotor.
Key Features:
  • V Rotor: Made of solid material, it offers aggressive material feed with up to two rows of knives, ensuring high throughput with low power requirements. Knives are reversible to reduce maintenance costs.
  • Intuitive Operation: Equipped with Siemens PLC control and touch display for easy adjustments and overload protection.
  • Hopper Design: The free-cutting hopper design prevents material bridging, even with bulky parts, and can be extended with lids and gas pressure springs.
  • F Rotor: Ideal for flexible materials, offering controlled feed behavior and precise cutting geometry.
  • Load-Controlled Ram: The hydraulic ram feeds material to the rotor, with options for manual or automatic control.
  • Interchangeable Screen: Allows for customization of shredded material size, with easy screen changes.
  • Durable Rotor Bearings: Offset design prevents dust ingress and facilitates maintenance.
  • Vibration Absorption: Rubber feet reduce vibrations, allowing flexible installation.
  • Material Discharge Options: Includes air suction, discharge screw, or conveyor belt, with expertise in conveyor technology.
  • WEIMA WAP Gearboxes: In-house manufactured for robustness, with features like a hydrodynamic start-up clutch for smoother operation.
  • Protected Hydraulics: Integrated into the machine frame for protection and compact installation.
Technical Highlights:
  • Rotor Specifications: Diameter of 260 mm, lengths ranging from 600 to 1,000 mm, and speeds of 80-125 rpm.
  • Drive Power: Ranges from 11 to 37 kW depending on the model.
  • Knife Configuration: Maximum number of knives varies by model, with sizes available in 40 mm.
  • Machine Dimensions: Vary by model, with weights ranging from 1,100 to 2,800 kg.
Machine Configuration Options:
  • Standard and optional features include control cabinets, material feed options, drive configurations, cutting geometry, and maintenance features.

WL 8 | Single-shaft shredder-2

TECHNICAL HIGHLIGHTS Intuitive operation thanks to Siemens PLC control with touch display To ensure that the electronics are optimally matched to the machine, we design, build and wire our control cabinets ourselves. We only use high-quality components - for example from Siemens or Rittal. Intuitive touch interfaces guarantee quick adjustments. Functions such as setting the ram cycle or stop ensure a high throughput. The built-in overload protection also prevents defects in the machine. Precise cut with high throughput with profiled V rotor The V rotor, specially developed by WEIMA, can be used...

WL 8 | Single-shaft shredder-3

DURABLE ROTOR BEARINGS thanks to offset design A rotor bearing must be robustly designed due to the extreme stresses it is subjected to while it’s in operation. To prevent dust or foreign matter from getting inside it, we have set it apart from the machine frame. This also makes it very maintenance-friendly and easy to access. Safe material feed with load-controlled ram The ram, which moves horizontally back and forth via hydraulics, feeds the material to the rotor. With WEIMA, it can be controlled or cycled automatically depending on the load. If required, of course, it can also be controlled...

WL 8 | Single-shaft shredder-4

TECHNICAL HIGHLIGHTS Optimally protected hydraulics installed in the machine frame Integrating the sensitive components of a hydraulic system into the machine frame has many advantages. Not only is it protected from dust, dirt and other external influences such as the weather, but it also makes the machine even more compact in its installation. A separate service opening provides easy access for maintenance. CLEAN DISCHARGE OF MATERIAL by suction, screw or conveyor belt Depending on your needs and frame design (elevated machine with conveyor belt cutout or side spout), you have the option of...
