In the concrete industry, ready-mixed concrete mixing plants have become the core equipment for urban construction, infrastructure projects, and large-scale industrial engineering. Different types of RMC plants are suitable for various production scenarios, with the two most common types being the Dry Mix RMC Plant and the Wet Mix RMC Plant.
If you plan to invest in a ready mixed concrete mixing plant and don’t know which type of RMC plant to choose, should you choose a dry mix concrete mixing plant or a wet mix concrete mixing plant? Which concrete mixing station is more suitable for your project? What are the advantages and disadvantages of the two types of concrete mixing plants? Is the investment return cost-effective? Can specialized solutions be provided?
If you currently have these issues, please read this article, and we will answer them for you. If you need guidance or assistance, please don’t hesitate to contact us, and we will respond to your message as soon as possible.
1. Dry Mix RMC Plant
What is a dry mix concrete mixing station?
The dry mix RMC plant mainly measures cement, aggregates, fly ash, additives, and other raw materials according to the formula accurately, and directly loads them into the mixing and transportation truck. The actual mixing process of concrete is completed by concrete mixer trucks during transportation, rather than in the concrete mixing plant.
Therefore, there is no need for a mixer, but for a mixer truck to mix on the transportation road. Dry mix RMC plants have the following advantages:
- Firstly, the investment cost is low, as there is no need for a large mixing host, resulting in lower overall equipment costs of approximately $25000- $80000.
- Secondly, it has a simple structure, small footprint, short installation cycle, and is suitable for temporary projects or contractors with limited budgets.
- Thirdly, it has strong flexibility and can be quickly demolished, making it suitable for small construction sites or highly mobile engineering projects.
However, dry mix concrete mixing plants also have some shortcomings, such as the mixing process being carried out in the mixer truck, which is greatly affected by driving conditions and travel time, and may affect the quality of concrete mixing due to bumps. Dry mix RMC plants are only suitable for engineering projects with short distances and are not suitable for long-distance transportation. Long-distance transportation can cause concrete segregation or slump loss, making it difficult to meet the strength requirements of concrete above C40.
2. Wet Mix RMC Plant
What is a wet mix concrete mixing station?
The wet mixing RMC plant is equipped with a mixing host inside the station, and all raw materials (including water) have been completely mixed before entering the transport vehicle. The transport vehicle is only responsible for transporting the mixed concrete to the construction site.
Therefore, wet mix concrete mixing plants require mixers, which have the following advantages:
- Firstly, the concrete quality is high and stable, and the mixing machine completes the mixing under controlled conditions with uniform quality, suitable for high-strength and large volume concrete.
- Secondly, it is suitable for large-scale projects such as subways, highways, airports, ports, etc., with high production capacity.
- Thirdly, the transportation radius is larger, as the concrete has already been formed and the quality does not depend on road bumps, making it suitable for a transportation radius of 5-15 kilometers.
- Fourthly, it is more in line with modern construction requirements, with a complete environmental protection configuration, and can be equipped with dust removal and recycling systems.
However, wet mix RMC plants also have some shortcomings, such as the need to configure mixing machines and more complex control systems, with an investment of approximately $80000- $300000. Site construction, installation, and debugging require more time and a professional team. The operation of the mixing host increases power consumption and maintenance costs.
3. Dry Mix vs. Wet Mix RMC Plant
| Feature | Dry Mix Batching Plant | Wet Mix Concrete Batch Plant |
|---|---|---|
| Quality of concrete | The standard deviation of tensile strength in dry-mix concrete plants is usually large, and there may be some differences between different loads. This is caused by differences in mixing time, truck shovel and drum conditions, traffic conditions, and many other external factors. However, the AGICO dry mix batching plant has already minimized these differences as much as possible. We have combined the characteristics of dry-mix batching plants and wet-mix concrete plant equipment to improve multifunctionality and applicability. AGICO dry mix batching plant can also produce concrete with a high mixing degree now. | On the contrary, all loads in the wet mix concrete batch plants are mixed at the same station and under similar conditions, making it easier to obtain concrete with a high degree of mixing. |
| Advantage | High efficiency, easy operation, and stable performance | High productivity, high quality, reliable performance, low investment, and long service life |
| Appearance | Simpler appearance and less equipment | Have more equipment relatively |
| Operating and maintenance cost | Lower operating and maintenance costs | Need more operating and maintenance costs relatively |
| Power consumption | Lower power consumption | Higher power consumption relatively |
| Construction performance | Can be carefully screened during the process to achieve the desired fineness, and it is easy to achieve the correct grade. | Lower than that of wet-mix batch plants. |
| Storage time | Can be stored for as long as possible because it will not solidify | The maximum storage time of wet concrete mixture shall not exceed 24 hours; Therefore, it must be used as soon as possible. |
| Mixing batches | Can be used for small-scale mixing | Cannot produce concrete in small batches |
| Mixer | Needs to be used in conjunction with the mixer | Contains a central mixer and the twin-shaft mixer can fully mix in a shorter time |
Overall, the Dry Mix RMC Plant is suitable for small and medium-sized contractors, temporary projects, and quick installation needs. Wet Mix RMC Plant is suitable for large-scale infrastructure projects and commercial concrete suppliers.
