MillNest Delumper

Delumper

Gentle. Targeted. Flow-restoring.

The MillNest Delumper MLUM gently breaks caked, agglomerated and lumped powder materials back into free-flowing particles — without over-grinding or damaging the underlying powder that caused agglomeration during storage, drying or transport.

The MLUM Delumper uses a controlled lump-breaking rotor to disaggregate caked, lumped and agglomerated powder without applying the high energy of a full-size mill. The rotor action breaks apart weak agglomerate bonds while leaving the underlying powder particle at its original specification.

MLUM is typically positioned before blending, dosing or packing — restoring free-flowing character after storage caking, post-drying agglomeration or transport compaction. The low-overgrinding configuration ensures the powder specification is not altered in the process.

Gentle lump breaking — designed specifically for de-agglomeration, not milling
Maintains underlying product particle integrity throughout
Reduces downstream blockage in conveyors, feeders and dosing systems
Particularly useful after drying, prolonged storage or bulk transport
Low-overgrinding configuration — powder specification unchanged
Available in food-grade SS 304/316 for food and pharma applications

MLUM is positioned upstream of blending, dosing or packing wherever caked or lumped powder is causing blockages, inconsistent feed rates or quality failures.
