Lump Crushers

Lump crushers break down lumps, crusts and agglomerates that can form during the storage, discharge or handling of powders and bulk solids. By reducing oversized material before conveying, dosing or further processing, they help maintain consistent material flow and reliable downstream operation.

Hosokawa offers different lump-crushing solutions depending on the material properties, required particle size and process conditions. Their compact design allows them to be integrated directly into powder and bulk solids processing lines.

Lumps and agglomerates can form through compaction, settling, moisture or prolonged storage and may interfere with subsequent conveying, dosing or processing. Lump crushers provide a simple and effective way to restore the material to a manageable particle size without requiring a dedicated milling process.

The appropriate configuration depends on factors such as the size and strength of the lumps, the required product size, throughput and material characteristics.

Product range

• Coarse lump crushers – For breaking down larger lumps, crusts and agglomerates.
• Fine lump crushers – For controlled reduction to smaller particle sizes.
• Fine lump crushers with sieve – For applications requiring a defined maximum particle size.
• Combined coarse and fine lump crushers – For one- or two-stage reduction of larger lumps and agglomerates.
