The new model 700-THX-50-ARI rotary batch mixer (photo) blends abrasive materials, such as concrete, premix, mortar mix, glass, fiberglass, refractories, tungsten powder and ceramics, in 1–3 min with minimized abrasive wear or product degradation. The mixer features abrasion-resistant steel contact surfaces, internal mixing flights with easy-to-replace wear plates and radial seals for dust-tight operation. It has a usable batch capacity of 50 ft3 or 4,000 lbs, and achieves uniformity, regardless of disparities in the bulk densities, particle sizes or flow characteristics of batch ingredients, according to the manufacturer. Its horizontal rotating vessel contains proprietary mixing flights that tumble, turn, cut and fold material gently, preventing degradation and imparting minimal energy to the batch. A stationary inlet and outlet at opposite ends of the vessel allow hard piping to upstream and downstream conveyors, process or packaging equipment or storage vessels. — Munson Machinery Co., Utica, N.Y.
