Thanks for the inputs. But I am not looking to reduce the volume of Styropor. I want some system by which I can grind it and use it as packing material and as light weight aggregate.
Styropor is BASF's brand name for expandable polystyrene, the white beaded insulation and molded packaging foam. Grinding into flakes or small particles is usually done by molders of Styropor as a way to use their scrap and reintroduce it into the molding process. The throughput and initial cost of these units make them too expensive for individual users unless you can purchase a used one.
Lately, the highest and best use of the Styropor waste stream has been densification or melting because you can get better truck utilization and premium pricing over the loose particles.
Having said all of that, you can usually purchase a used agricultural hammer mill and drive it with either electric or gasoline powered motor. The key is to use a screen that yields the size of particle you need. Watch your fingers!!

I would think a chain flail system would do what you need. Are you looking to buy or build? If buy, try looking in GlobalSpec If build, feel free to contact me.

1. Take a squirrel cage fan (the size of a home A.C. Blower) and modify it by cutting an axial slot large enough to pass pieces of the foam into it.
2. Form a chute to fit and weld it to the fan. (Be sure to make the chute long enough so no one can get their hands into it!)
3. Fashion a pusher device which will fit into the chute to allow the pieces to contact the squirrel cage. Be sure to put a positive stop to prevent it from contacting the fan. (Safety First!)
4. Make a bag out of something like cotton fabric for collecting the particles and connect it to the outflow flange.
