Abstract: The present disclosure is directed to a mobile batching plant having a primary frame carrying the cement storage, batching and weighing system and a plurality of rigidly connectable and detachable secondary modular frames connected in tandem each secondary modular frame carrying a combination batch and storage hopper having dispensing gates with an endless aggregate conveyor beneath the hopper gates. One sand and from one to three aggregate modules can be carried without affecting plant width. A fifth wheel for connection to a tractor is carried by the primary frame and a transport wheel assembly is connected to the last modular frame to render the entire plant transportable over the highway. The hoppers carried by the modular secondary frames are loadable by a small front end loader without the need of ramps because of their low profile.
