What Is a Dry Batch Concrete Plant

Oct 18, 2022

The dry batch concrete plant consists of aggregate batching machine, cement supply system, water supply system, cement weighing system, water weighing system, control system, etc. It is mainly used in sparsely populated areas to avoid segregation of wet concrete due to long-distance and long-term non-stop movement in the mixer truck, resulting in poor concrete quality.

It does not have concrete mixer. After the powder is weighed and batched, it is directly discharged into the mixing station in the concrete mixer truck. Therefore, it has these parts: aggregate feeding system, powder feeding system, control system, batching machine, etc., but there is no concrete mixer and liquid material conveying system.

After completing the batching and weighing, the aggregate and cement are put into the mixing tank of the concrete mixer, and the preparation is completed under the mixing action of the mixing tank, and the water and additives are provided by the mixer. So we call such a station a dry mixing station.

The wet batch concrete plant some or all of the above materials (including water) into a concrete mixer in the middle. After mixing, the concrete is discharged into a mixer truck or mixer to deliver the concrete to the construction site. It should be noted that during transportation, the mixer or mixer truck should be rotated at an appropriate speed to prevent the concrete from setting. It has the following parts:

1. JS twin shaft concrete mixer

We adopt the twin shaft concrete mixer in mixing plants at home and abroad, which can mix fluidity, semi-dry-hardness and dry-hardness and other concretes. It has the advantages of high production efficiency, energy saving and environmental protection.

2. PLD batching machine

The material weighing system is a key component that affects the quality of concrete and the cost of concrete production. It is mainly divided into three parts: aggregate weighing, powder weighing and liquid weighing.

3. Screw conveyor

The main equipment of the material conveying system is the screw conveyor.

4. Cement silo

The main equipment of the material storage system is the cement silo.

5. Control system

The main equipment of the control system is the operating room and the operating system. Generally, the control system of the small mixing station available on the construction site is simpler, while the system of the large mixing station is relatively complex.
