Wet Mix Concrete Batching Plant

As an important equipment for concrete production, wet mix concrete batching plant has a wide range of applications in many fields. The following is a detailed description of wet concrete mixing plant, including output, structure, working principle, product features and application scope.

I. Output
The output of wet mix concrete batching plant is affected by many factors, including equipment type, mixing process, concrete ratio and so on. Generally speaking, the productivity of the wet mixing process is relatively slightly lower than the dry mixing process, because it needs to add water in the mixer and mix the water with the concrete raw materials. According to industry data, the hourly output of the wet mix concrete plant is about 25-240 cubic meters, but the specific output needs to be determined according to the equipment model and the actual situation. For example, some large wet mix concrete plants such as HZS120 can reach a capacity of about 120 square meters per hour under ideal conditions, but this limit may not be reached under the wet process.

II. Structure
Wet mix concrete batching plant is mainly composed of the following parts:
- Mixing host: usually adopts double horizontal shaft forced mixer, which is characterized by high mixing efficiency and good mixing uniformity. There are mixing blades and mixing cylinders in the mixing machine, which are used to mix cement, aggregate, water and other materials.
- Material weighing system: it is responsible for weighing various materials accurately according to the set ratio. The system includes electronic scales, sensors, controllers, etc. to ensure stable quality of concrete.
- Material conveying system: including aggregate conveying, cement conveying, water conveying and other parts. Aggregate conveying often adopts belt conveyor or bucket elevator; cement conveying may adopt screw conveyor or pneumatic conveying system; water conveying is realized through water pump and pipeline.
- Material storage system: including cement silo, aggregate silo, additive silo, etc., for storing various raw materials. These silos are usually made of steel or reinforced concrete structure with sufficient strength and sealing performance.
- Control system: as the brain of the mixing plant, it is responsible for the operation control of the whole mixing plant. The control system usually adopts PLC programmable controller or touch screen control system to realize automation and intelligent control.

III. Working Principle
The working principle of wet mix concrete batching plant is as follows:
- Material preparation: store cement, aggregate (such as sand, stone, etc.), additives and other materials in the corresponding silo, and ensure that the quality of various materials meet the specification requirements.
- Weighing and batching: According to the set ratio, the control system directs the material weighing system to weigh all kinds of materials accurately. After weighing, all kinds of materials are sent into the mixing machine through the conveying system.
- Stirring and mixing: Add appropriate amount of water into the mixing machine and start the mixing machine for mixing and stirring. During the mixing process, the mixing blades keep turning and stirring the materials to make them fully mixed. Parameters such as rotation speed and time of the mixing host can be set according to different concrete types and project requirements.
- Discharging: after mixing is completed, the concrete will be fed into the concrete tanker or other transportation means through the discharge port and transported to the construction site.

IV. Product Characteristics
Wet mix concrete batching plant has the following features:
- Good mixing uniformity: As water is added in the mixing process, it makes the friction and collision between materials more adequate, which is conducive to improving the uniformity of concrete.
- Higher production efficiency: although the production efficiency of wet mixing process is slightly lower than that of dry mixing process, it can still meet the production demand in many occasions.
- High degree of automation: the adoption of advanced control system and automation equipment realizes the automatic operation and intelligent management of the mixing plant.
- Good environmental protection performance: by equipping with environmental protection facilities such as dust collector and sound insulation equipment, it effectively reduces noise, dust and wastewater discharge.

V. Application Scope
Wet mix concrete batching plant is widely used in industry, agriculture, transportation, national defense, water conservancy, municipal and other construction projects. Especially in the projects that require higher concrete quality and larger production volume, wet mix concrete plant can give fuller play to its advantages. In addition, wet mix concrete batching plant is also suitable for occasions with high requirements on concrete quality, such as high-rise buildings, bridge projects and so on.

To summarize, wet mix concrete batching plant occupies an important position in the field of concrete production with its unique advantages. With the continuous progress of technology and environmental protection requirements, the wet mixing plant will develop in the direction of more efficient, environmentally friendly and intelligent.
