The modern world can barely exist without concrete. It is the structure that makes up a huge portion of every construction made today. So what makes concrete so sturdy and dependable that no structure of importance (or of lesser interest) is without it?
Essentially, concrete is a mixture of two components: aggregates and paste. The former is the main component that determines the strength, durability, and flexibility of the concrete, whereas the former binds it all together into a solid mass. Modern aggregates include various types of components, such as gravel and stone. Cement serves as the primary paste material.
Concrete batching is the process of mixing the aggregate and paste together. It involves a machine called a concrete batching plant, which could be mobile, or may consist of a series of machines complete with conveyor technology for large-scale production. There are two main types of batch plants, ready mix and central mix.
For large-scale plants, operation typically runs in four parts: aggregate feeding, power feeding, conveyance and storage. A conveyor belt delivers the aggregate into the weighing hopper, and when the materials’ weights meet the standard amount, the hopper opens up and delivers the aggregate to a mixer, where it will be mixed for a set period of time.
