I got a crush on you ...

The most important feature of a prebreaker grinder is its power :
If you want to grind big chunks of EPS, which fall off your contour cutter, no matter if it is 10 or 35kg/m3, you don´t want to get stuck with this small "grandmother´s coffee grinder type" or a dust-producing-hammer-mill, no :

You need the REAL grinder, comminuting up to 20m3/h of EPS scrap pieces to granules, featuring a quick change screen system.

You need the VBM 1350, based on the design of the good old WIESER grinders.

Although a screen with 12mm holes will not make very much dust, the smaller screen sizes will, so a de-duster is highly recommended.

New slow-rotating prebreaker/grinders are more expensive, but make almost NO dust.

Recycling System

DeDuster

Dust extraction system for EPS regrind,
preferably situated after the fine-grinder, before the regrind silo.
Some dust will occur when using screens with small holes,
therefore it is advisable to configure the recycling plant including a dedusting system.

For proper mixture of EPS regrind and virgin material you will need a MIXING and BLENDING station such as the STARMIX system :

2 Silos with 5 m3 volume each are filled with material (virgin and regrind), rotary airlocks ensure proper mixing according to the percentage ( 0 - 50%) as selected on the control panel. Capacity of up to 150m3/h is just enough to fill the cavities of standard moulds.
