Size Reduction

What is size reduction?

The first step of recycling is reducing plastic waste of various shapes and sizes to a consistent size that the washing, separation and extrusion stages can handle. İnan Tech’s size-reduction group covers shredders for pre-breaking, crushers (granulators) for homogeneous flake and pulverizers for fine powder — all built to complement one another under a single engineering approach.

Which machine is right for you?

The choice depends on the type, size and thickness of the material and the target output. A shredder suits the pre-breaking of large, thick parts; a crusher produces clean, homogeneous flake; and a pulverizer serves powder and filler applications. In most plants these machines work together as a sequential line.

How does size reduction work?

Size reduction works by progressively shrinking material through mechanical cutting and tearing forces. Because baled, hollow or thick parts cannot be processed to the desired fineness in a single machine, the stages complement one another: a coarse pre-break first, then homogeneous flake, and where needed a fine powder. At each stage the blade geometry, rotor speed and screen aperture are selected to deliver a consistent particle size suited to the next step.

A typical line follows this sequence:

1. Pre-breaking: a shredder breaks bulky, baled material into coarse pieces at low speed and high torque, feeding the next machine without choking it.
2. Homogeneous flake: a crusher (granulator) reduces the pre-broken material to even-sized flake set by the screen aperture.
3. Fine powder: a pulverizer grinds flake or granule to micron-level powder for powder and filler applications.

This stage sits right at the start of the recycling line; by producing a consistent feed, it lays the groundwork for the washing, separation, drying and extrusion steps to run smoothly.

Choosing the right size-reduction machine

The right machine is determined by weighing your material and your target output together. No single criterion is enough on its own; the following points are usually considered side by side:

• Material type and form: film, rigid parts, bales, pipe or profile each behave differently.
• Part size and thickness: bulky, thick input often calls for a pre-breaking stage.
• Contamination level: soil, sand and foreign matter influence the blade and screen selection.
• Target output: whether you want homogeneous flake or micron-level powder directly determines the machine type.
• Blade and screen configuration: blade geometry and screen aperture shape the output size and cutting character.
• Noise and dust management plus sequential line layout: positioning the machines together so they feed one another affects efficiency.
