Overview of Plastic Crusher Machine

Corresponding Content:
- Equipment Nature: A professional industrial device designed for crushing various plastic materials into small particles (2-10mm) through high-speed impact and shear forces; a key pre-processing equipment in plastic recycling and reprocessing lines, distinguishing from shredders by smaller and more uniform output particle size.
- Applicable Materials: PP/PE/LDPE/HDPE plastic films, sheets, injection molding scraps, blow molding waste, plastic bottle flakes, agricultural film fragments, ABS/PS engineering plastic scraps, etc.
- Core Processes: Material feeding → high-speed impact crushing → screening classification → qualified particle discharge; integrates crushing and screening functions to ensure particle size uniformity.
- Core Value: Reduces plastic materials to small particles suitable for subsequent pelletizing, mixing or direct reuse; improves melting efficiency of downstream pelletizing equipment by 40%; realizes resource recycling of plastic scraps, reducing raw material waste.
- Applicable Enterprises: Plastic product manufacturers (injection molding, blow molding, film blowing), plastic recycling plants, pelletizing production lines, small and medium-sized waste plastic treatment workshops.

Frequently Asked Questions

What is the difference between a plastic crusher and a plastic shredder?

Crushers produce smaller and more uniform particles (2-10mm) for direct subsequent processing; shredders produce larger fragments (5-20cm) mainly for volume reduction, requiring further crushing for pelletizing.

Can it crush plastic materials with printing ink or impurities?

Yes; the shear and impact forces can break down ink layers and separate loose impurities; it is recommended to match with a cleaning module for high-impurity materials to improve particle purity.

How often do the blades need to be replaced?

Under normal working conditions, blades need to be sharpened every 2-4 months; service life is 8-12 months depending on the processed material and impurity content.

Is it compatible with existing pelletizing lines?

Yes; the discharge port can be customized to match different types of pelletizing equipment; supports seamless connection and continuous production.

What are the delivery time and payment terms?

Standard models: 10-20 working days; customized models: 20-30 working days; flexible payment terms (T/T, L/C) are supported; small-batch trial orders are acceptable.
