Abstract
A device enabling the timely removal and subsequent recycling of residues remaining in a pouring chute through which the load of a cement from a mixing drum of a mobile delivery vehicle was discharged. A strainer on a movable arm attached to the vehicle is placed under the chute to receive an effluent which results from spraying the inside of the nozzle with water. Solid particulates are retained by the strainer and a slurry which emerges from the strainer is pumped into the mixing drum, allowing the separated materials to be recycled when the vehicle returns to its base.
