What is a Batching Plant? (The Ultimate Guide)

A batching plant is a piece of equipment used to mix concrete. It is typically made up of a hopper, a mixer, and a conveyor belt. The hopper is used to store the raw materials for concrete, such as sand, gravel, cement, and water. The mixer is used to combine the raw materials and mix them together until they form a homogeneous mixture.
