J&H began operation as an equipment manufacturer in 1975, manufacturing process screens, material handling and conveying systems for the chemical fertilizer industry. Our unique “Optimizer” tensioning system for the screens set J&H apart from the other screen manufacturers. The conveying equipment development included many sizes and types, from very small bucket elevators and belt conveyors to very large machines used in ship loading and high capacity mineral processing. The focus of the industry was processing machinery that was simple and rugged enough to endure the harsh environment of the production process from mine to ship.
