July 8, 2019 – Munson Machinery has introduced a new standalone lump breaker that can be used for papermaking ingredients that have solidified in storage. 

The De-Clumper Lump Breaker model RDC-1530-SS contains a support base and in-feed hopper designed for standalone operation.

The self-standing configuration can be fed from a variety of upstream sources 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. In pulp and paper, this could be colour pigments, or ingredients such as starch, kaolin clay, talc, dispersants or resins. 

Material entering the 380 mm by 760 mm in-feed 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 25 to 64 mm in diameter.

Powered by a 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 castors 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 30 kW and inlets to 1220 mm square.
