Lump Breaker
Our lump breaker is designed to reduce large clumps of agglomerated material into a smaller, more uniform, particle size to improve downstream processing and/or conveying characteristics. It should not be considered a true size reduction machine that will grind materials to a specific size.
Progressive Products, Inc recommends testing should be done on all material to confirm size selection. It is also recommended that level sensors be used downstream of the lump breaker to prevent over-filling of the feeding device being used.
