The Model LB550 lump breaker (photo) can reduce agglomerates as large as 10 in. (250 mm) into particles with an average size as small as 0.08 in. (2 mm) with minimal heat generation or fines at rates from 2.4 to 28 ton/h. Its large 21 in. × 16.4 in. inlet allows the direct discharge of compacted materials from 50-lb sacks or bulk bags without the need for an intermediate controlled-feed mechanism. Side and end doors, which can be either bolted or hinged and interlocked, provide easy inspection and access to interior components. The unit can de-lump dried or hygroscopic materials that have agglomerated due to dampness or compaction, and is said to operate quietly due to slow shaft rotation. Typical applications include intermediate sizing of product for improved drying and granulation prior to tableting, regrinding of out-of-specification material for reclaim and pre-grinding prior to a secondary fine-milling process or to speed up dissolution in liquid reactors. — Kason Corp., Millburn, N.J.
