摘要: This invention describes apparatus and method for recycling undelivered cement left as residue in trucks. Undelivered at the end of working day is deposited on a shaker screen under action high pressure water jets which trap large aggregate force onto first belt collection. Sand, fall through second traps sand that delivery to collection area. The remaining cement, slurry collected trough pumped settling tank having an auger periodically mixes prevent hardening. A skimmer located uppermost portion collects clear used clean previously mentioned. combination with fresh provide charge waiting lost now recycled reused rather than being wasted.
