Working Principle of Concrete Mixer Batching Plant

The working principle of a concrete mixing plant is to meter, transport and mix raw materials such as cement, sand, stone, water and admixtures according to the preset ratio, and finally produce concrete that meets the engineering requirements. The whole process is usually managed by an automated control system to ensure production efficiency and concrete quality.

Raw material storage and supply

Aggregates (sand, stone): delivered to aggregate silos by loaders and transported to batching systems via belt conveyors or hopper elevators. Powders (cement, fly ash, etc.): stored in cement silos and transported to metering systems via screw conveyors. Water and admixtures: stored in water tanks and admixture tanks respectively, and transported to metering devices via pipelines.

Raw material metering

Aggregate metering: Aggregates such as sand and stone are weighed by electronic metering systems. Powder metering: Powders such as cement and fly ash are weighed by screw weighing systems. Water and admixture metering: flow meters or weighing systems are used to accurately control the amount of addition.

Conveying and feeding

After the metering is completed, the aggregate enters the mixer directly through the belt conveyor or hopper. Cement and other powders are fed into the mixer through a screw conveyor. The measured water and admixtures are transported to the mixer through a pipeline.

Concrete mixing

Start the mixer and mix all the raw materials evenly to ensure that the concrete meets the set quality standards. The general mixing time is 30-90 seconds, which may vary for different models of mixers.

Mischer Der Mischer ist das Herzstück der Betonmischanlage. Er ist für das gleichmäßige Mischen der verschiedenen Rohstoffe verantwortlich. Zu den gängigen Mischertypen gehören Doppelwellenmischer, Einwellenmischer und Zwangsmischer. Die Wahl des Mischers hängt von den Produktionsanforderungen, der Art des Betons und der Größe der Anlage ab.

System zur Lagerung von Zuschlagstoffen Es dient der Lagerung von Zuschlagstoffen wie Sand und Stein, in der Regel in separaten Lagern, wobei jedes Lager über ein unabhängiges Beschickungssystem verfügt, das die Zuschlagstoffe automatisch zum Mischer befördern kann.

Zementlager und Fördersystem Der Zement wird vom Zementlager zum Mischer über eine spezielle Förderschnecke oder ein pneumatisches Fördersystem befördert.

Betonmischer-Dosieranlage

Die Betonmischanlage ist eine spezielle Ausrüstung für die Herstellung von Beton, die im Bauwesen, im Straßenbau, bei großen Infrastrukturprojekten und in anderen Bereichen weit verbreitet ist. Sie mischt Rohstoffe wie Zement, Sand, Kies, Wasser und Zusatzmittel in einem bestimmten Verhältnis zu einheitlichem Beton und liefert ihn zur Verwendung auf die Baustelle. Die Betonmischanlage ist eine der wichtigsten Infrastrukturen bei modernen Bauprojekten und gewährleistet die Qualität und stabile Versorgung mit Beton.Hauptbestandteile der Betonmischanlage Dosiersystem Das Dosiersystem ist ein wichtiger Bestandteil der Betonmischanlage, mit dem die Rohstoffe (wie Zement, Sand, Steine, Wasser und Zusatzmittel usw.) entsprechend dem vorgegebenen Verhältnis automatisch abgewogen und zugeführt werden. Die Genauigkeit des Dosiersystems wirkt sich direkt auf die Qualität des Betons aus.

Main components

(1) Aggregate supply system
Aggregate silo: used to store aggregates such as sand and stone. Generally, there are multiple silos to meet the needs of different proportions.
Conveying system: Aggregates are transported to batching machines using belt conveyors or hopper elevators.
Batching machines: Accurately measure various aggregates to ensure stable concrete quality.
(2) Powder supply system
Cement silo: stores cement or fly ash. Usually, it adopts a closed structure to prevent dust pollution.
Screw conveyor: used to transport powder from the silo to the mixer to ensure production continuity.
(3) Water and admixture supply system
Water tank: stores water required for mixing. Some large sites use underground water tanks.
Admixture system: includes storage tanks, metering pumps, conveying pipelines, etc., used to accurately add admixtures to improve concrete performance.

(4) Measuring system
Aggregate metering: sand and stone aggregates are accurately measured through an electronic weighing system.Powder metering: cement, fly ash and other powders are accurately measured using a spiral scale.Water and admixture metering: flow meters or weighing metering devices are used to ensure the accuracy of concrete mix ratio.
(5) Mixing system
Main mixer: core equipment, generally a twin-shaft forced mixer is used to ensure uniform mixing of concrete.
Discharging system: after mixing, the concrete is discharged through a pneumatic discharge door or hydraulic system and transported to a concrete tanker.
(6) Control system
Automation control: including PLC system and computer console, which can accurately control each link and improve production efficiency.
Data storage and management: the production data of each batch of concrete can be recorded to facilitate quality traceability.
Remote monitoring: some advanced systems support remote control, which is convenient for management personnel to check the production status at any time.
