Munson Machinery releases new abrasion-resistant lump breaker

Material entering the 24 in. (610 mm) square inlet is reduced in size by 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 1 in. dia. (25.4 mm) apertures in the bedscreen. Other bedscreens are available with apertures ranging from 1/32 - 2.5 in. (25 - 64 mm) dia.

Powered by a 7.5 HP (5.6 kW) motor with gear reducer and a rugged chain and sprocket drive, the synchronised 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.

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.

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.

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 48 in. (1219 mm), and up to four rotors driven by motors up to 40 HP (30 kW).
