The Munson rotary batch mixer with integral lump breaker provides inline de-agglomeration of compacted bulk materials before blending batches gently with total uniformity in one to three minutes. Material entering the system is de-lumped by dual rotors with three-point, single-piece, stainless-steel breaking heads that rotate with minimum clearance inside a curved, perforated bed screen. The synchronized shafts rotate at 120 RPM to prevent heating and degrading of the product. On-size material passes through bed screen apertures, which range from 1/16 in. to 2½ in. (25 mm to 64 mm) in diameter, immediately prior to entering the stationary inlet of the mixer. As the mixer’s horizontal drum rotates, proprietary mixing flights tumble, turn, cut, and fold the material, imparting minimal energy to the batch. The company says total uniformity is achieved in less than three minutes regardless of the disparities in the bulk densities, particle size, or flow characteristics of batch ingredients. The internal flights lift and direct the entire batch into the stationary discharge spout for evacuation with no residual “heel” of material requiring manual removal. That helps to eliminate waste and improve product quality while facilitating rapid, thorough cleaning.
