Abstract:
1. A portable concrete plant for preparing ready mix concrete, the portable concrete plant comprising: a frame having at least one set of wheels attached thereto for supporting the frame above a ground surface and permitting the frame to be moved along the ground surface; a cement storage region attached to the frame, wherein the cement storage region stores cement, and wherein the cement storage region has a cement entry port and a cement exit port; a sand storage region attached to the frame, wherein the sand storage region stores sand, and wherein the sand storage region has a sand entry port and a sand exit port; a rock storage region attached to the frame, wherein the rock storage region stores rock, and wherein the rock storage region has a rock entry port and a rock exit port; a water storage region attached to the frame, wherein the water storage region stores water, and wherein the water storage region has a water entry port and a water exit port; a slurry mixer attached to the frame, wherein slurry mixer has a slurry mixer entry port and a slurry mixer exit port, wherein the cement exit port and the water exit port are operably connected to the slurry mixer entry port, wherein the slurry mixer prepares a slurry from cement and water; and wherein the slurry mixer exit port is proximate a system exit port; a conveyor system attached to the frame, wherein the conveyor system receives rock from rock exit port and sand from the sand exit port and transports the rock and sand to the system exit port; and further comprising a mixing apparatus mounted on the frame proximate the system exit port for mixing the rock, sand and slurry wherein the mixing apparatus imparts a swirling motion to the rock, sand and slurry as the rock, sand and slurry pass through the mixing apparatus.
