There are various kinds of Ready Mix Concrete plants used to mix concrete aggregators, these plants are made or designed for specific locations or conditions. Moreover, these RMC plants are also designed by following several high quality and safety standards and they are modified to accommodate certain situations of RMC mixing. Ready Mixed On-site Concretes are those mixing which are produced directly on the construction site, as its name implies. The production of RMC requires using proper formulas to determine the amount of material and steps to obtain the desired consistency and efficiency. Concretes are manufactured as per set procedures and established standards in batching plants. These materials are made of different elements to deliver the best results to construction sites.
In this reading, various kinds of RMC plants, their categories, and RMC mixing options will be discussed. Here, we are going to describe the different types of Ready Mix Concrete Plants and Their Concrete Mixing plans:
1. Dry Batch RMC Plants
These kinds of RMC plants produce uniform or similar kinds of the concrete mix through the mixing plan and action of the truck mixer. The mixing actions of Dry Batch mix concrete are basically followed by a twofold mechanism. It should be considered that the complex movement of well-mixed plastic concrete in the drum would be done effectively.
In the beginning, you should neglect the blade action and focus on the rotation of the drum for both concrete internal friction and friction against the drum inside the surface, it will make the concrete appear to move up the right-hand wall to the drum. There are approximately two factors that affect the height that the concrete can climb gravity surpasses it and makes it fall.
Concrete falling point increases with the increment in linear velocity, it happens when drum surface velocity would be based on its angular velocity and inside the diameter of the drum. Through this, concrete workability declines which lead to rising concrete falling points. In this batch plant spinner works at the speed of 22-27 rpm (Normal speed can be considered as 10-14 rpm), so the concrete spins with the full speed with the drum surface which creates problems for concrete by avoiding the falling point
2. Wet Batch RMC Plants
There are various types of wet batch systems and tools which are plant-based mixers. In other words, wet batch RMC plants and systems use different kinds of components such as cement, aggregates, and water to mix the wet paste of concrete in the system. Respectively, the output of wet batch RMC plants is greater than dry batch plants, that is the reason it is frequently used as large plants. However, the wet batch of concrete plants become necessary in the case mortar production is a requirement.
There are different types of mixer sizes that could be between the range of 0.8 m2 to 6 m2, the huge mixer drum can appropriately mix 6 m2 plastic concrete in around forty-five seconds. Furthermore, there are several factors like required output, predominantly mixed supplies, plant geometry, space, the material used for mixture, life span, expenses, and more whichever is used can directly affect the production of Ready Mix Concrete.
There are different kinds of wet batch mixers available in the market, these options are –
- Rotating Drum Mixer
- Fixed Trough Mixer
- Reversing Drum Mixer
3. Half-Wet Batch Ready Mix Concrete Plants
Half wet systems include premixing of sand, cement, different aggregators and water etc. in order to make slurry, after that, the slurry and aggregates are added to the truck. Half wet system not only decreases the wear and tear on central mixer units but also substantially decreases the delay time of RMC batching.
4. Combination Batch RMC Plants
Both dry batch and wet batch systems are also combined in this type of batching plant. These kinds of concrete are mixed in dry leg bur small mixers with approx. 0.8 – 2 m3 is employed in order to present concrete to the customers.
Ready Mix Concrete is normally recommended for the large projects that require a high volume of production and mixture. Ready Mix Concrete tends to be better for many projects, also, it helps in controlling further cost when concrete is produced in a plant environment.
