UTICA, NY A new model 15X15-SS low-profile Rotary Lump Breaker from Munson Machinery reduces agglomerates and friable materials being discharged from process equipment, storage vessels and shipping containers.
Material entering the 15 in. (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 the bedscreen ranging from 1/32 to 2½ in. (25 to 64 mm) in diameter.
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. Both the rotor assembly and the bedscreen can be removed rapidly for cleaning or replacement.
At 11 in. (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 de-agglomerating 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.
According to the manufacturer, it is built to withstand heavy usage and is simple to maintain; bearings can be lubricated through external fittings and are isolated from the product processing area with multiple labyrinth air purge seals.
Constructed of #304 stainless steel, finished to sanitary standards and designed for thorough washdown, the unit is suitable for food, dairy and pharmaceutical applications as well as industrial applications where cross-contamination between batches is a concern. It is also offered in #316 stainless steel, carbon steel and abrasion-resistant steel (AR-235).
Also offered are higher capacity models with up to four rotors, up to 40 HP (30 kw) and inlets to 48 in. (1219 mm) square.
