The mobile batch plant, also known as a portable concrete plant is a very productive, reliable and cost effective piece of equipment to produce batches of concrete. It allows the user to batch concrete at most any location then move to another location and batch concrete. It was invented in 1956 by Vince Hagan and was patented in 1966 as a convenient alternative to stationary batch plants that cannot be moved easily (U.S. patent #3,251,484). Portable plants are the best choice for temporary site projects or even stationary locations where the equipment height is a factor or the required production rate is lower.
