A concrete plant, also known as a batch plant or batching plant, is a device that combines various ingredients to form concrete. Some of these inputs include sand, water, aggregate (rocks, gravel, etc.), fly ash, potash, and cement. There are two ...
From there, gravity does the rest. Volumetric mixers use augers to move concrete. These are similar to the blades in the batch mixer but smaller. Inside the mixer, an operator feeds data into the mixer and several augers feed aggregate and cement together. Water is added to the mix and larger augers blend the components.
