What is the average shredding speed of the Polystruder GR PRO plastic shredder?

The shredding speed of the Polystruder GR PRO plastic shredder depends on multiple factors, including the material type, thickness, size, motor speed, and more. However, when shredding objects that are 30mm in size, made of PLA with a 1.6mm wall thickness and 20% infill, the Polystruder GR PRO plastic shredder has a shredding capacity of approximately 3kg per hour.

Are the shredding blades user replaceable?

Yes, the blades of the Polystruder GR PRO plastic shreddercan be replaced by the user.

What is the maximum size of plastic parts that the Polystruder GR PRO plastic shredder can shred?

The Polystruder GR PRO plastic shredder can shred plastic parts up to a length of 100mm.

Are there any limitations on the types of plastic that the Polystruder GR PRO plastic shredder can accept?

There are virtually no limitations on the types of plastic that the Polystruder GR PRO plastic shredder can accept. However, it's important to note that certain plastics with harsh additives, such as carbon fiber, wood, steel, and similar materials, can significantly reduce the lifespan of the shredding blades.

How much power does the Polystruder GR PRO plastic shredder consume?

The Polystruder GR PRO plastic shredder features a highly efficient brushless DC motor with a maximum power draw capacity of 300W. However, on average, it consumes only 150W per hour.

How does ShredAI work?

ShredAI is an in-house developed custom shredding algorithm exclusively for Polystruder GR PRO plastic shredder that operates by continuously monitoring real-time data such as motor power consumption, blade direction changes, and temperature. Based on this information, ShredAI makes decisions to automatically adjust the motor speed, optimizing the shredding speed for optimal performance.

Is it possible to shred other materials other than plastic?

We designed the Polystruder GR PRO plastic shredder to efficiently shred plastic waste. We do not recommend to shred any other material besides plastic. Using it to shred other material besides plastic will void the device warrantly.

What is the average dimensions of shredded plastic parts?

Average shredded plastic pieces varies between 3mm to 5mm. There could be some instances where some thin parts that as big as 30mm can fall in between blade spacers inside the collector bin. However we recommend shredding at least 3 times to achieve the more granular material size.

What is the average noise level of the Polystruder GR PRO plastic shredder machine during normal operation?

We conducted several tests during the shredding process and found that the average noise level is 62 dBA, with a maximum of around 75 dBA. The test was conducted using a black PETG plastic object. Please note that the noise level is generated by the crushing sound during the shredding process and may vary greatly between different material types.
