Do you know dry batch concrete plant?

A dry batch concrete mixing plant is a special type of concrete production equipment. Its main feature is that it is not equipped with a central mixer. Instead, it weighs dry raw materials such as sand, sement, and fly ash in proportion and directly unloads them into a concrete transport mixer truck. Water is added and mixing is completed during transportation. It is a sement qarışdırma zavodu that produces concrete by dry mixing.

Compared with traditional wet batch concrete mixing plants, dry batch concrete mixing plants have many advantages such as energy saving and environmental protection, high production efficiency, and a wide range of applications. They are irreplaceable, efficient, and environmentally friendly concrete production solutions in modern construction projects.

How does a dry concrete batch plant work?

The workflow of a dry concrete batch plant is relatively simple. It mainly weighs the raw materials (such as sand, daş, sement, külün uçmaq, və s.) in proportion and unloads them directly into the concrete transport mixer truck. Sonra, water is added and mixed during transportation to finally form concrete. Var 6 steps in the whole process.

1. Raw material storage and supply

Xammal anbarı: Aqreqatlar (qum, daş) are usually stored in open-air aggregate yards. Aggregate yards are divided into sections according to the types of aggregates (such as coarse sand, fine sand, crushed stone, və s.).
Powders (sement, külün uçmaq, mineral powder, və s.) are stored in powder silos. Powder silos are closed steel structure containers used to prevent powders from moisture and contamination. Admixtures are usually stored in special liquid tanks.

Raw material supply:
Aqreqatlar: Aggregates are transported from the yard to the aggregate batching machine by a loader or belt conveyor. Powders are transported from the powder silo to the measuring hopper by a pneumatic conveying system. The admixture is delivered to the metering device through the pumping system.

2. Raw material metering

The aggregate batching machine weighs different types of aggregates according to the set mix ratio. After weighing, the aggregate is transported to the aggregate collection hopper through a belt conveyor. Powders such as cement and fly ash are transported to the powder metering hopper for weighing through a screw conveyor. After weighing, the powder falls into the aggregate collection hopper. The admixture is accurately measured by a flow meter or a weighing device. After the metering is completed, the admixture is temporarily stored in the metering hopper and waits for subsequent addition to the mixer truck.

3. Raw material mixing and loading

After the aggregate, powder and admixture are initially mixed in the aggregate collection hopper, they are directly unloaded into the concrete transport mixer truck parked below through the discharge port.

4. Transportation and mixing

After the concrete transport mixer truck receives the raw materials, it adds an appropriate amount of water to the tank of the mixer truck according to the requirements of the mix ratio. Sonra, the tank of the mixer truck starts to rotate and mix. The mixer truck continuously stirs during transportation to ensure the uniformity of the concrete.

The mixer truck transports the concrete to the construction site. Since the concrete produced by the dry concrete mixing plant is mixed during transportation, the transportation distance can be relatively long and is not strictly limited by the distance from the mixing plant to the construction site.

5. On-site unloading and use

After the mixer truck arrives at the construction site, the operator will adjust the speed and mixing time of the mixer truck according to the construction requirements to ensure that the concrete reaches the best state. The mixer truck then unloads the concrete into the concrete pump truck, concrete chute or other construction equipment.

The construction personnel pour the concrete into the formwork according to the construction requirements and carry out the construction of the concrete structure.

6. Cleaning and maintenance

After each production, the aggregate batching machine, powder conveying equipment, metering device, və s. need to be cleaned to prevent residues from affecting the next production. In particular, the powder pipeline and metering hopper need to be cleaned regularly to prevent the powder from agglomerating.

Regularly check the operating status of the equipment, including belt conveyors, screw conveyors, weighing devices, mixer trucks, və s., to ensure the normal operation of the equipment. For vulnerable parts (such as conveyor belts, spiral blades, weighing sensors, və s.), they need to be replaced in time to extend the service life of the equipment.
