Sanitary Lump Breaker Includes Side-Removal Screens

Synchronized shafts rotate at approximately 100 rpm to avoid heating the product.

A new sanitary lump breaker from Munson Machinery features side-removal bedscreens for rapid, thorough wash down. The all-stainless, low-profile model RDC1515-SS reduces agglomerates and friable materials being discharged from process equipment, storage vessels and shipping containers.

Material entering the 15-inch (381 mm) square inlet is reduced in size by dual rotors with three-point, single-piece, stainless-steel breaking heads rotating with minimum clearance inside a curved, perforated bedscreen. On-size material exits through apertures in twin bedscreens ranging from 1/32 to 2-1/2 inches (25 to 64 mm) in diameter.

The new unit with side-removal bedscreens can remain in place. This design can allow for thorough sanitizing in less time than conventional units, which generally are unbolted from upstream and downstream equipment to access bottom-mounted bedscreens, Munson Machinery notes. Powered by a 3-hp (2.24 kw) motor with gear reducer and serpentine timing drive, the synchronized shafts rotate at approximately 100 rpm to avoid heating the product.

At 11-inches (279 mm) high, the unit is designed to fit in restricted spaces between bulk storage, handling, processing and packaging equipment. With optional feed hoppers and support structures, it can also operate independently. The unit is recommended for deagglomeration of free- or non-free-flowing bulk materials such as salt, sugar, spices and resins, and size reduction of easy-to-break materials such as friable food products and other compacted powders.
