Types of Ready Mix Concrete Plants
There are many different types of ready mix concrete plants and their mixing action
Dry Batch Ready Mix Concrete Plants
This type of ready mix concrete plant produces uniform concrete mix through the mixing action of the truck mixer. The mixing action is basically a twofold mechanism. Consider the complex movement of already well mixed plastic concrete in the drum. At the beginning, neglect the blade action, then rotation of the drum and both concrete internal friction of the concrete and its friction against drum inside surface make the concrete appears to move up the right-hand wall of the drum as shown in Figure-2.
Wet Batch Ready Mix Concrete Plants
There are various types of wet batch systems and the wet batch system is plant based mixer. This means that different component of concrete mixture such as cement, aggregate, and water is mixed in the system. Comparatively, the output of wet batch concrete plant is greater than dry batch concrete plant that is why it is frequently seen as large plants. Moreover, the wet batch concrete plant is necessary in the case mortar production is required. There are different mixers sizes that range from 0.8 m2 to 6 m2 and the largest mixer drum can adequately mix about 6 m2 plastic concrete in around forty five seconds. Furthermore, there are several factors for example, required to output, predominant type of mixes supplied, plant geometry, available space, initial and entire life expenses, upon which specific mixer is decided to be chosen.
Half-Wet Batch Ready Mix Concrete Plants
Half wet system includes premixing of sand, cement, and water to make slurry, after that, the slurry and aggregate are added to the truck. Not only does the half-wet system decrease wear and tear on central mixer units but also substantially decline the time of batching.
Combination Batch Ready Mix Concrete Plants
Both dry batch and wet batch system is combined in this type of batching plant, and most of concrete is mixed in dry leg bur small mixers with 0.8-2 m3 is employed to deliver concrete to the customer.
