Plastic Shredding Equipment

Overview

Plastic shredding equipment performs the first stage of size reduction in a recycling or processing line: oversized plastic – pipe, purgings, film, blocks and bulky scrap – is cut into smaller, more manageable pieces that can then feed downstream granulation, washing, pelletizing or reprocessing.

Shredding is distinct from washing and from pelletizing; it is a pre-processing size-reduction step, not a machine that contains those stages. Whether a shredder is needed, and which type to choose, depends on the material and the process that follows.

Choose the Size-Reduction Stage

The suitable machine depends on the feedstock, maximum piece size, required particle size and downstream process rather than a single capacity label.

• Single-shaft shredder: primary size reduction for bulky plastic feedstock such as purgings, pipe and large solid plastic pieces. Large solid blocks are normally directed to a single-shaft configuration.
• Double-shaft shredder: two counter-rotating shafts for project-specific configurations handling waste plastics, rubber tires, wood, metals, cables or electronic waste. The material discharges directly below the shredding chamber; this machine does not use a screen.
• Plastic crusher: finer size reduction for suitable smaller, hollow or production scrap where knife and screen selection is tied to the material and target size.
• UR-600 integrated shredder-crusher: combines primary shredding and secondary crushing in one system for suitable rigid plastic feedstock, removing the need for a separate interstage belt conveyor.

Materials and Configuration Boundaries

Knife material, hardness and wear resistance are selected for the actual feedstock. Double-shaft configurations can be prepared for waste plastics, rubber tires, wood, metals, cables and electronic waste, but one configuration should not be assumed to cover every material. Concrete, batteries, engines and complete vehicle bodies are not presented as confirmed applications.

How We Select and Configure Size-Reduction Equipment

Useful details to share include:

• Material and material form
• Maximum piece dimensions
• Metal, mineral or other contamination
• Target particle size
• Required throughput and operating hours
• Downstream process
• Feeding and discharge method
• Factory layout
• Electrical standard
• Automation requirement

Why Choose URIDGE

URIDGE configures size-reduction equipment around the customer's material and process requirements. Material testing can be used where feedstock behaviour or the required cutting configuration needs to be confirmed before production.
