During cutting insulating boards from blocks reusable cutting waste is generated which in general becomes recycled. Via the mixing and dosing unit recycled and virgin material is mixed and re-converted to blocks.
A double rotary star valve unit with combined outlet is located below a 10 m³ storage-silo for recycled and a 10 m³ storage-silo for virgin material. The percentage of regrind to the virgin material is step-less adjustable from 5 % to 50% by different rotation speed of the rotary star valves. Electronic speed control of the driving motors guarantees a constant mixing-ratio. By switching off the dosing unit for regrind only virgin material is supplied to the block-mould.
The filling levels of the storage silos get monitored and controlled by level sensors.
