Powerful batching equipment for modern buildings

Concrete mixing station is a kind of equipment for producing concrete, an indispensable mixing production line in modern construction projects. The main working purpose of concrete mixing station is to mix various raw materials (cement, sand, stone, water, etc.) in a certain proportion to make the required concrete. This article will explore the working principle of concrete mixing station in depth, so that you can clearly understand how concrete mixing station works.

Working principle of concrete batching plant

The working principle of concrete batching station mainly depends on its internal batching system, mixing system, conveying system, storage system and control system.

The batching system is responsible for accurately weighing various raw materials (such as cement, fly ash, sand, etc.) according to the set proportion, and then feeding them into the mixing system.

The mixing system uses high-speed rotating mixing blades to fully mix the raw materials with water to achieve a uniform effect. The material conveying system is responsible for aggregate conveying (belt conveyor or bucket elevator), cement conveying (screw conveyor or pneumatic conveying system) and water conveying (water pump and pipeline).

The storage system includes cement silo, aggregate silo, additive silo, etc., which are used to store various raw materials. Finally, the evenly mixed concrete is transported to the concrete transport truck through the conveying system and transported to the construction site.

During the mixing process, the mixing time and mixing speed of the mixer need to be set according to different mixing ratios and mixture quality to ensure that the mixture reaches the required uniformity..

How does a concrete batching plant work accurately?

The workflow of a concrete mixing plant is generally divided into 5 steps: batching, mixing, discharging, transportation and cleaning.

1. Batching

First, in the feeding stage, the prepared cement, aggregate, sand and admixtures (such as fly ash, etc.) are added to the hopper in a certain proportion, and then they are sent to the weighing machine for weighing and metering using the conveying equipment. The weighing and conveying of each material are precisely controlled by the control panel to ensure the quality and consistency of the concrete.

2. Mixing

Next, in the mixing stage, the accurately weighed raw materials are gradually added to the mixer, and the raw materials are mixed with water. The mixer is usually composed of a mixing drum, a lifting device and a transmission device, etc., and the high-speed rotating mixing blades are fully mixed to make the concrete reach a uniform state. In the mixing drum, there are multiple mixing blades, each of which can fully mix, stir and turn the raw materials during the rotation of the mixing drum. The mixing time is set by the control system to ensure the stable quality of each batch of concrete.

3. Discharging

Then, in the discharging stage, the mixed concrete is discharged from the mixing drum and transported to the concrete transport truck through a conveying system (such as a conveyor belt, a screw conveyor or a concrete pump). The concrete mixing station uses an automatic unloading mixer, which can dump the concrete into the discharge hopper through a lifting device, and then dump it into a concrete mixer truck or a storage tank as needed.

4. Transportation

The concrete transport truck transports the concrete to the construction site and unloads the concrete from the concrete pump truck through a hydraulic unloading system for construction use.

5. Cleaning

Finally, in the cleaning stage, the residual concrete in the mixer and conveying equipment is cleaned and maintained to ensure the normal operation of the equipment and extend its service life.

In short, the concrete mixing station achieves a fully mixed effect by mixing, stirring and turning the raw materials in a certain proportion, thereby producing concrete that meets the requirements. Its working principle mainly relies on the stirring and mixing functions of the mixer and the assistance of the conveying equipment, so that the concrete raw materials can be evenly mixed and stirred to form concrete of uniform consistency within a certain period of time, thus meeting the needs of engineering construction.
