Shredder

Glass shredder

Powerful pre-shredding for glass and more

PTG shredders were initially developed for pre-shredding car and bulletproof glass panes that need to be separated from foreign materials such as foils and frames.

They tear foil-reinforced panes into small pieces so that a secondary crusher such as our PTKS impact crusher can then cleanly separate foil and glass. Standard glass panes without foil and many other products can also be pre-shredded.

up to 3 mfeed size

up to 80 mmbulletproof glass thickness

below 250 mmpiece size for bulletproof glass

Efficient glass recycling

Low wear costs

Glass, and especially glass with tear-resistant PVB film, is difficult to recycle. That is why keeping wear costs in operation as low as possible was a priority during development.

Minimal wear costs

Thanks to the slow rotation of the shafts, wear costs stay minimal even in glass.

Quiet pre-shredding

The slow rotation ensures quiet pre-shredding ahead of subsequent production.

Even feeding

Both pre-shredders deliver an even and continuous feed material.

Also as a feed unit

With hopper superstructures of different sizes, they can also be used as a feed unit.

2 or 4 shredder shafts – the choice is yours

Different sizes for different tasks

PTG 2 – 2-shaft shredder

For materials that are easier to shred, the 2-shaft shredder is usually sufficient.

PTG 4 – 4-shaft shredder

Car glass panes and multi-reinforced bulletproof glass panes up to 80 mm thick can be fed in one piece.

Bulletproof glass, window glass and frames

Even the most demanding tasks

Shredding bulletproof glass plates up to 80 mm thick is probably the most demanding task for the PTG shredder.

Plates up to 3 m long with up to eight foil layers
Shredded into pieces below 250 mm
Window glass and attached frames are cleanly separated thanks to four powerful geared motors
Various shredder shafts and teeth for a wide range of options

Pre-shredder meets hammer mill

Powerful partners

Combination of hammer mill and PTG pre-shredder

The PTG pre-shredder can be combined with many machines. The PTRG with hammer rotor is the most suitable.

With just two machines, foil and glass can be cleanly separated, or foreign materials such as window frames can be removed from the glass after pre-shredding. By adjusting the gaps and rotational speeds of both machines, the combination processes a wide range of products, also outside glass recycling.
