Lump Breakers


Lump breakers are designed to reduce softer and abrasive products such as filter cakes, foodstuffs, chemicals, fertilizers, and fly ash into sizes that can be further processed downstream. They can be placed in-line to reduce materials into manageable sizes for conveyors and/or other process equipment or as a stand-alone unit with customized support structures and appropriate safety measures included. All models are available in mild steel, stainless steel, or other alloys with various power transmission options to suit most industrial applications.

Depending on process requirements and capacity, five standard lump breaker machine models are available. Additional options include twin or single-shaft designs, portable bases, and inlet feed hoppers that can be adapted to suit individual process needs.

Complimentary services include factory and field pilot testing for equipment selection and performance optimization.
