Amerind was the first company to manufacture bulk AN/FO trucks. AN/FO trucks are the simplest trucks of all the different kinds of bulk trucks. AN/FO trucks mix ammonium nitrate and fuel oil (AN/FO). The original trucks were fabricated with a hammer mill system to crush the AN since only agricultural grade Ammonium Nitrate was available. Hammer mills can still be an option if an HD AN/FO is required. Amerind AN/FO trucks come in a variety of sizes and configurations. Capacities vary from 4 tons to 24 tons. Discharge systems can be made with an overhead auger, side auger, or pneumatic discharge. With over 50 years of bulk truck manufacturing, let the staff of expert engineers design a bulk truck to meet your needs.
