A concrete mixing plant, also known as a batching plant, could accommodate huge amounts of sand, gravel, water, and rocks to make big batches of fresh concrete. There are two kinds of mixing plants: the ready-mix batch plants and the central-mix batch plants.
What is a Ready-Mix Batch Plant?
A ready-mix batch plant combines all ingredients required in making concrete, minus water. Operators add water to the mixture after transferring it to mixing trucks. These trucks have a drum which turns while transporting the concrete, combining all ingredients together while going to the construction site.
You've got three different mixing options when you use ready-mix concrete. You can elect to set the mixer at slow speed while on the road, and increase the speed at least five minutes ahead of use. You can also mix the concrete at the mixing yard and put the drum rotation on slow speed during transportation. Lastly, you may mix all ingredients and turn the drum at medium speed during delivery. The concrete will be completely mixed and ready for use once you get to the job site.
What is a Central-Mix Batch Plant?
Central-mix batch plants are a sort of concrete plant that combines and mixes all ingredients before transferring concrete to mixing trucks. They'll use fixed plant-mounted mixers where you place the ingredients of concrete, including water. Central-mix plants then churn everything into concrete, after which you could transfer it to trucks. The truck mixer merely needs to agitate it a bit during transport to help keep the concrete fresh.
Which one should you use for your project?
Your choice depends on your preference and distance from the job site. Ready-mix batch plants, or 'dry batch,' are great if your plant is farther from the construction. Adding the water later allows you to have a fresh batch of concrete. Central-mix batch plants or 'wet batch,' however, are great if you're able to set it up as close to the construction site as possible. These mixing plants produce more high-quality cement as they produce a more consistent mixture. Central-mix plants also make more concrete mixtures faster than trucks because a mixer truck's drum has limited space. Finally, your mixing trucks will have longer life if you use central-mix batch plants. You will not put an excessive amount of strain on the drums by raising the speed. Your trucks will tolerate wear and tear more than if you use them alongside ready-mix batch plants.
The type of concrete mixing plant you choose would be determined by your project's time line, the quality of cement you need, and your budget. Make sure you think about these carefully when selecting a batching plant.
