Munson Machinery launches new sanitary lump breaker

World Cement,

Munson Machinery has released a new DeClumperTM lump breaker model RDC-3030-SS. The lump breaker reduced agglomerates and compacted materials to their original particle sizes.

The machine is 279 mm high and fits in restricted spaces between bulk storage, handling, processing, and packaging equipment. With operational feed hoppers and support bases, it can also operate independently. Material that enters the 762 mm2 inlet is reduced in size by four rotors with three-point, single-piece breaking heads, rotating with a minimum clearance inside twin, curved, perforated bedscreens. Material that is on-size exists through apertures in the bedscreens, ranging from 25 mm dia. to 64 mm2.

The unit is equipped with interlocked side-removal bedscreens that can be removed without tools for cleaning, changing, or inspection. This is unlike units that must be unbolted from upstream and downstream equipment to access bedscreens.

Dual, independent 7.5 kW motors with a gear reducer and chain and sprocket drives provide capacity and redundancy, rotating the synchronised shafts at approximately 120 RPM to avoid heating the product.

The unit is recommended for deagglomeration of free- or non-free-flowing bulk chemicals, fertilizers, flakes, cement powders, carbon black pellets, or hygroscopic products, as well as the size reduction of large chunks of friable products and compacted powders.

According to the company, it is constructed to withstand heavy usage and is simple to maintain. Bearings can be lubricated through external fittings, are isolated from the product processing area with air purge block seals, and can be fitted with optional air purge packing seals with split housings.

The unit is constructed with #304 stainless steel, finished to sanitary standards, and is available in #316 stainless steel, carbon steel, and abrasion-resistant steel (A-235). Other models are also available with between one and four rotors, single or dual motors, and inlets/outlets from 305 mm2 to 1200 mm2, or rectangular configurations.
