1. SYSTEM DESCRIPTION

The residual concrete is unloaded from truckmixers, concrete pumps into the DISCHARGE HOPPER which is located on the rear of the machinery. At the same time the washing nozzles begin to work and push the concrete into the seperation tank.

Once in  the seperation tank, the concrete settles on the bottom while the first flighting raises it again so that is seperated in its main components: Particulate of cement and Balast. Thanks to the difference of density between two materials, the balast ttends to fall down on the bottom, while the particulate of cement stays in suspension for the sufficient time to be carried as far as the outlet of the tank, where a decentation barrier lets the cementatious water leaking out the tank below a movement from the bottom toward the top; thus any possible residue of thin aggregate, such as sand, is collected by the second flighting which turns in the opposite sense to the first and push the balast toward the extraction cups. These ones take the material conveyed by the flightings and put it on a belt conveyor, located under the balast outlet on the side of the tank. During their extraction, the aggregates are carefully washed by some cleaning nozzles that spray high-preesure water against the cups; thus all balast is ready to be reused while cups are kept always clean.

Contemporary to the balast extraction, the particulate of cement goes into the water holding tank. The water storage silo can contain 30 m³ of cementatious water and is equipped with an agitator whose function is to keep the particulate of cement always in suspension, avoiding its solidification on the bottom of the silo.
