There are 5 main systems in a typical concrete batching plant: mixing, material weighting, material delivery, material storage, and control unit. Some plants also have a selection of additional features to control dust pollution and improve energy efficiency. Let’s explore some of the key systems and concrete batching plant components in more depth.
• Concrete Mixer
The mixing system is separated into two operations, the forced mixer and the self-falling mixer. The forced mixer is used for the manufacturing of concrete from cement powder. Meanwhile, the self-falling mixer is used to stop ready-mixed concrete from solidifying during transit and is rarely used in stationary concrete mixing stations.
• Material Weighing System
The accuracy of the material weighing system is vital for the production of high-quality concrete. The system is used to accurately measure cement powder, aggregates, and binding liquid, to ensure the correct ratios for the desired concrete mix formula.
• Material Delivery System
This system is comprised of multiple modules depending on the configuration of the plant. To transport the powdered ingredients, a screw conveyor system is used. Large concrete mixing plants have pneumatic conveying systems. For aggregate delivery, belt transporting systems and hopper delivery systems are available. Plants with hopper aggregate delivery systems have a smaller footprint and are thus more often seen in mobile concrete batch plants. In contract, belt aggregate transportation systems have the advantage of higher efficiency, long transportable distances, and lower fault rates. The benefits of concrete batch plants with auger delivery systems is that the systems have a simple structure, increased operational safety, and lower costs. Water and liquid additives are typically transported using pumps.
• Material storage system
Silos are used for storing all the different raw materials in a concrete batching plant. There are separate silos for aggregates and powder. The cement powder silo must be completely enclosed to prevent dust pollution and it’s normally constructed from steel.
• Control Units
The central control system is used to monitor and control all functions within an entire concrete mixing plant configuration. Most expensive models have remote control options and are completed computerized. Control units for mini concrete batch plants tend to consist of basic manual controls.
Above we have talked about some of the main concrete batching plant components in a typical configuration.
Concrete Batching Plants For Sale
Those looking to get started in the world of concrete manufacturing need to take time to explore the different concrete batching plants for sale in the marketplace. Not all plant designs are equal and some are much more efficient than others. Furthermore, there can be a huge difference in price between different mixing plants depending on the size and features of the setup.
In terms of technical parameters, some key ones to take note of during procurement are mixer capacity, mobility, degrees of automation, mixer type, dimensions, weighing systems (electronic or manual), control system, storage mechanisms, feeding mechanisms, discharging rate, power, energy consumption, etc. The price is also a key factor that will influence any buying decision.
