The engineering concrete batching plant is generally built next to the construction site. It is mainly used on a certain project. The general configuration is relatively simple, which can meet the concrete required for the production of the project. The purchaser is mainly used to produce concrete for them.
What Is Volume Batching of Concrete? Batching of concrete means measuring different ingredients of concrete (i.e. cement, sand, coarse aggregate and water) before mixing it. When this measurement is done on the basis of volume, we call it Volume Batching.
Dec 24, 2011 · Weight batching is the professional one, which is always recommended. Basically, you measure each quantity by mass (using a large weigh equipment) and batch the components in a controlled environment. You see this type of batching in large concrete batching plants which have large equipments. That is weight batching.
