Quickly Reduce Agglomerations with our Durable, Compact Lump Breaker Line of Equipment

Lump Breaker in Bag Dump Station

Designed to provide a simple, efficient means of reducing agglomerated materials, our LumpMaster® line of equipment is both durable and economical.

As your complete source for all bulk material handling needs, we have engineered the LumpMaster® specifically to reduce natural agglomerations which can occur during storage or shipping or to reduce deliberately compacted materials. The equipment includes counter-rotating dual shafts, outboard bearings and a direct coupled drive. Our equipment is designed to reduce lumps to approximately ¾” to allow material to be effectively handled by downstream conveyors.

The LumpMaster® Operation

The LumpMaster® operates by material entering through the opening in the top. Pieces of material too large to pass through the rotating shaft pins and the stationary combing bars are crushed as the shaft weldments rotate. The material continues to be crushed until it is small enough to pass through.

Lump Breaker Installation

Lump breakers are a necessary component of most material handling systems and best used in an inline operation at the discharge point of raw material. To best accommodate this important material handling dynamic, we have engineered our complete LumpMaster® line to compactly fit under automatic unloading equipment, manual bag emptying stations, or at the discharge point of storage silos or containers.
