The ring mixer is only used in the production of multicolor slabs.
Its purpose is to blend and homogenize the various mixtures coming from the different mixers.
A very robust gearbox drives:
- The big basin that contains the blend
- The 2 x 4 cylindrical bars (coated in a special material)
- The 2 specially-designed scrapers
The resulting mixture is sent to the next stage through the central, cylindrical, sliding piece operated by means of a hydraulic piston.
The two scrapers are designed so as to leave no blind zones, leaving the ring mixer completely empty.
