Original Press Release:

Stand-Alone Lump Breaker

Utica, NY - Munson Machinery has introduced a new De-Clumper™ Lump Breaker model RDC-1530-SS with support base and infeed hopper designed for stand-alone operation.

Unlike units permanently installed between upstream and downstream equipment, the self-standing configuration can be fed from a variety of upstreamsources including handheld containers, and can straddle downstream equipment, drums, boxes or mobile bins for processing, storage or packaging.

The unit de-lumps bulk materials that have agglomerated or solidified during storage or shipment, returning products to their original particle sizes and flowability.

Material entering the 15 x 30 in. (381 x 762 mm) infeed throat via the hopper 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 2½ in. (25 to 64 mm) in diameter.

Powered by a 5 HP (3.7 kW) motor with self-lubricating chain and sprocket drive, the synchronized shafts rotate at approximately 120 RPM to avoid heating the product. The bedscreen can be removed rapidly for cleaning or replacement.

According to the manufacturer, the rugged design withstands heavy use and is easy to maintain; bearings can be lubricated through external fittings and are isolated from the product processing area with UHMW air purge block seals.

Constructed of #304 or #316 stainless steel, the unit is available with casters for in-plant mobility, and can be finished to food, pharmaceutical or industrial standards. It is also offered in abrasion-resistant stainless steel to withstand demanding industrial applications.

Also offered are high capacity models with up to four rotors, up to 40 HP (30 kW) and inlets to 48 in. (1219 mm) square.

Other size reduction machinery offered by the company includes SCC™ Screen Classifying Cutters, CIM™ Pin Mills, Accu-Size™ Attrition Mills, Rotary Knife Cutters, HammerHead™ Hammer Mills and Titan™ Shredders. Blending equipment includes Ribbon, Paddle and Plow Blenders, Rotary Batch Mixers, Vee-Cone Blenders, Fluidized Bed Mixers, Rotary Continuous Mixers and Variable Intensity Blenders.
