Modern recycling facilities rely on specialized bottle crushers to efficiently process PET and HDPE containers. These machines transform bulky plastic bottles into compact flakes, preparing material for washing and pelletizing in the recycling stream.
Types of Bottle Crushers
1. Vertical Shaft Crushers
-
Single rotor design
-
Throughput: 200-800 kg/hour
-
Output size: 10-25mm flakes
2. Horizontal Shaft Crushers
-
Dual rotor configuration
-
Throughput: 500-2000 kg/hour
-
Specialized for whole bottle processing
3. Wet Crushers
-
Integrated water spray
-
Reduces dust and static
-
Common in washing lines

These bottle crushers are game changers for recycling efficiency! The 10:1 volume reduction is insane.
Wish my local recycling center had one of these industrial models 🤔 Would make sorting so much easier
The spec sheet looks promising, but how loud are these machines in operation? Noise pollution is a real concern.
As someone who works in waste management, I can confirm the horizontal shaft crushers work best for our HDPE containers 👌
Do these crushers work for plastic bottles that still have some liquid in them? Asking for a friend who runs a bar.
0.3-0.8 kWh/kg seems reasonable, but what’s the price range for these machines? The compact model caught my eye.
The environmental impact section is eye-opening! More cities should invest in this tech to reduce landfill waste.
Fun fact: I’ve seen these in action at a recycling plant – the speed they process bottles is mind-blowing!
Anyone know if the vertical crushers struggle with milk jug caps? We’re having contamination issues at our facility.
Great breakdown of different crusher types! We’re currently researching which model to get for our municipal recycling program.
