November 30, 2018 – Munson Machinery has released a new model of its rotary lump breaker to break chunks of agglomerated abrasive or friable materials that have compacted during storage or shipment, conditioning them for downstream processing or conveying.

The RDC-2424-MS “De-Clumper” rotary lump breaker reduces the size of material entering the 610 mm square inlet using dual rotors with three-point, single-piece, AR-235 abrasion-resistant steel breaking heads rotating with minimum clearance above a curved, perforated bedscreen.

On-size material exits through 25 mm-diameter apertures in the bedscreen. Other bedscreens are available with apertures ranging from 25 to 64 mm in diameter.

The unit is recommended for breaking lumps in product flows of bulk materials such as cement powders, sodium or calcium carbonates, fertilizers, and bulk chemicals of all types.

Powered by a 5.6 kW motor with gear reducer and a rugged chain and sprocket drive, the synchronized shafts rotate at approximately 120 RPM, offering high throughput rates with minimal heat generation. A side-mounted bedscreen can be rapidly removed for cleaning, replacement or maintenance.

The compact, low-profile design allows inline placement in restricted spaces between upstream and downstream processing, packaging or bulk storage equipment. With an optional feed hopper and support structure, it can also operate as a stand-alone unit.

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 air purged shaft seals.

Suitable for industrial and chemical applications, it is also offered in 304/316 stainless steel, finished to sanitary standards for food, dairy, pharmaceutical or industrial applications.

The company also manufactures higher-capacity models with square or rectangular inlet openings up to 1220 mm, and up to four rotors driven by motors up to 30 kW.
