Drum contents are mixed with process water containing hydration stabilizer and discharged into the aggregate classifier through an intake trough or grated drive-over hopper.
Stage #2 - Aggregate
Aggregates are removed using the Knelson Concrete Classifier (KCC) while slurry containing cement, fly ash and sand, finer than #200 mesh, flows into the Recovery Tank.
Stage #3 - Recovery & Storage
While in storage, slurry is kept at a controlled specific gravity, degree of hydration and temperature.
Stage #4 - Batch Preparation
Slurry is prepared for use as mixing water by automatically adjusting the specific gravity in flow to provide production consistency.
Stage #5 - Batch Delivery
Slurry is pumped to a batch tank at the batch plant and held in storage before being weighed or metered into the fresh production.
Stage #6 - Quality Control
The ready-mix batch computer controls the final discharge of slurry from the Concrete Recovery System into the fresh concrete as mixing water. Mix designs can be modified by the producer to compensate for fine solids in the mixing water or in many cases, the batch plant computer will automatically compensate for these fines.
