Luton has rich experience in designing and manufacturing the concrete batching plant. The concrete mixing station adopts advanced process, each component and equipment has unique advantages. How does a concrete batching plant work? What are the advantages of working process of Luton concrete mixing plant?
Working Process & Principle of Concrete Batching Plant
1. The aggregates will be fed into bins by wheel loader or belt conveyor.
2. When batching the materials, the doors are opened by the cylinders and each aggregate discharges into their own weighing hopper for accurate accumulated weighing or individual weighing. Microcomputer automatically alarms when overweight.
3. After aggregates batching finished, they will be transported onto inclined feeding belt conveyor by flat belt conveyor
Features of Luton belt conveyor
- Our inclined feeding belt conveyor adopts semi-closed design, waterproof and dust proof.
- Maintenance walkway is designed at two sides of the inclined belt conveyor, easy for belt maintenance and with emergency stop pull switch, make sure easy maintenance and safety.
- Central has a tension device, ensure adequate tension to prevent belt slippage. The top has automatic cleaning device, scraper and belt cleaning, ensure belt as clean as new.
4. Material transported from the feeding inclined belt conveyor to the transition hopper in the upper part of the host mixer for temporary storage.
- Aggregate waiting hopper is a transition hopper that plays the role of a temporary aggregate storing, it shortens the cycle working time in a mixing station.
5. The dust removal device makes aggregate, cement, coal ash generated collected and prevent pollution. Power stored in silo which is composed of silo body, top roof dust collector, level indicator, inlet-tubes, manual butterfly valves, broken arch devices and other components.
6. Cement powder is transported by screw conveyor into the weighing hopper for metering.
Luton power metering hopper employs precise weighing sensors to ensure accurate powder weighing.
7. Water and admixtures transported through the pipeline to the respective weighing hopper for weighing, after weighing, the butterfly valve below the admixture weighing hopper then open, the admixture discharged into the water weighing hopper for mixing and dilution, then discharged to the host mixer via a booster pump.
Luton JS twin-shaft compulsory mixer
- LUTON Group developed the JS series twin-shaft compulsory mixer with high mixing efficiency, good uniformity, good sealing performance, safety, and high reliability etc.
- The mixer is mainly made up of mixing system, feeding systems, discharge systems, water supply systems, electrical systems and other components. Mixing barrel is welded together, mixing cylinder liner inlaid with five kinds, with countersunk head screws are firmly coupled with the barrel. Ensure the liner interchangeability.
- Spindle seal with new LUTON patented sealing technology, multiple seals, imported original seal, ensure the sealing reliability.
- Mixing blades adopt new generation of double helix with continuous stirring, replacing the traditional shovel blade mixing blades, mixing time can be shortened more than 50% percent, and stirring evenness increases more than 15 percent.
- Mixing blades are with double-helix shape, the spiral arrangement of the mixing blades curved to form a double helix and two opposite rotation axis, at the same time that the material vigorous radial and axial propulsion movement intensifies, making the material in the mixing bucket as a boiling status and mixed in a short time.
Luton concrete batching plant uses top automatic lubrication pump, centralized lubrication for all parts to ensure that the shaft seal durability.
The spray device is designed in right above of the two spindles and parallels with them, making the host water spray mixing process more uniform. Pressure pump high-pressure water jet, can quickly cleans residues adhered to the two spindles, keep the spindle always as clean as new.
Power supply is with safety lock design for the sake of life respect. In use of advanced digital control system for centralized control of every part of the operation of the equipment, software designed perfectly, check the statistical production date at all times.
Internal equipped with desk, cabinet, displays, monitors, air conditioners, printers and other equipment, can monitor real-time job status in mixing station.
The last commands issued from the control system, the completed stirred material injected to concrete mixer truck by discharging hopper.
