A high-rate portable self-contained combination screening/dosing/mixing plant is mounted on a single tractor trailer for highway travel in most states without requiring travel escort vehicles. The plant has a nominal capacity of about 100 tons of soil or dirt per hour, and includes an apparatus train for preliminary separation of large objects, hopper storage, uniform feed rate, shredding-pulverization, particle size screening, additive dosing, mixing and conveyance to an elevated position for transfer to a dump truck, bin or pile.
