Abstract
A method of operating a concrete batching plant includes loading aggregates into an aggregate storage bin divided into compartments from the ground level by wheel loader, discharging the material from storage bin through batching gates fitted into a weighing hopper, hydraulically lifting the aggregates after being weighed in the weighing hopper, conveying cement through a screw conveyor into a cement weigher and discharging the same into a mixer, mixing and compacting the aggregates for a pre-determined time, discharging the mixed and compacted concrete into a concrete carrying hopper, transporting the concrete carrying hopper to a desired height, and loading the concrete into mobile transit mixer or concrete pump, based on the site requirement.
Claims9
A concrete batching plant with reduced cycle time, comprising:
- an aggregate storage bin divided into compartments for receiving aggregates comprising sand and stones of different sizes;
- a weighing hopper configured to receive the aggregates from the storage bin;
- a base structure for discharging a required amount of the aggregates into the weighing hopper mounted on a load cell placed below the storage bin by gravity through batching gates, wherein the aggregate storage bin is configured to be set at a height close to ground level;
- a wheel loader configured to load the aggregates directly into the storage bin;
- a lifting arrangement configured to hydraulically lift the weighing hopper with an inclination of a predetermined angle;
- a gate placed below the weighing hopper and configured to discharge the aggregates into a mixer;
- horizontal cement silos for supplying cement to the mixer;
- a screw conveyor with an inclination configured to provide a dose of the cement to the mixer;
- a cement weigher configured to weigh the cement;
- a water weigher for weighing water before supplying water to the mixer;
- and
- a concrete carrying hopper travelling on a rail hydraulically for discharging contents of the concrete carrying hopper into a transit vehicle.
A concrete batching plant, comprising:
- an aggregate storage bin including a plurality of compartments configured to receive a material comprising sand and stones of different sizes at ground level from a wheel loader;
- a plurality of batching gates filled at a bottom of the storage bin, and configured to discharge the material from the storage bin;
- a weighing hopper configured to receive the material from the storage bin and weigh the material;
- a first lifting arrangement configured to hydraulically lift the weighing hopper from a height of between about 2 meters and about 3 meters, to a height of between about 3 meters and about 3.5 meters above ground level;
- a screw conveyer configured to convey cement;
- a cement weigher configured to receive the cement via the screw conveyer;
- a mixer configured to receive the cement from the cement weigher;
- a water supplying apparatus configured to discharge water into the mixer via at least one of gravity, a pump, and a pressure nozzle, wherein the mixer is configured to mix and compact the material, the water and chemicals for a predetermined time to create a mixed and compacted concrete;
- a concrete carrying hopper configured to receive the mixed and compacted concrete from the mixer;
- a second lifting arrangement configured to lift the concrete carrying hopper with the mixed and compacted concrete to a desired height, wherein the second lifting arrangement includes at least one of a hydraulic lift, a rail, a rack-and-pinion, and a rope;
- and
- at least one of a mobile transit mixer and a concrete pump configured to receive the mixed and compacted concrete from the concrete carrying hopper.
