Accommodate larger pieces
A 120 × 90 mm jaw opening and stepless 0–30 mm gap setting support coarse and pre-crushing tasks.
RETSCH / LARGER FEED. FRONT ACCESS.
BB 250.
More feed flexibility. Easier access.
Accept feed below 120 × 90 mm with a front-access crushing chamber, a 10 L collector and continuous-operation options. Published throughput is up to 300 kg/h, with final fineness below 2 mm under suitable conditions.
Explore the equipment and access details.

THE MODEL IN FOCUS
Larger feed with front access.
Simplify chamber access
The front door gives direct access to the crushing chamber. A wear-indicating scale helps monitor the breaking jaws.
Plan the next process step
Use the 10 L collector for batch work or discuss an outlet arrangement for continuous operation. A BB 250 / DM 200 cyclone combination is available for staged sample preparation.
*Feed size, final fineness and throughput depend on the material, jaw selection, gap setting and configuration. Published capacities are not simultaneous performance guarantees.
PUBLISHED MODEL DATA
The technical
picture.
BB 250 uses pressure for coarse and pre-crushing of medium-hard, hard, brittle and tough materials.
Feed size, final fineness and throughput depend on the material, jaw selection, gap setting and configuration. Published capacities are not simultaneous performance guarantees. Confirm current electrical and configuration requirements before ordering.

JAW MATERIALS & CONFIGURATION
The details shape
the result.
Match wear materials and the complete crushing route to the sample and the analysis.
Breaking jaws & wear plates
Published tool-material options for BB 250: manganese steel, stainless steel, tungsten carbide, steel for heavy-metal free grinding, stainless steel 316L, NiHard4. Confirm the exact combination and wear contribution for your material; a named heavy-metal-free grade does not eliminate every possible source of sample contamination.
Batch collection & process-line versions
Use the 10 L collector for batch preparation or discuss an optional process-line version for continuous operation. Feeding, collection, protection and electrical requirements depend on the installation.
Hoppers, collection & continuous discharge
Discuss the hopper arrangement, collection funnel with outlet and larger collection vessels. The standard 10 L collector supports batch preparation. Review dust handling, access and installation around a continuous workflow.
OPTIONAL CYCLONE COLLECTION
Recover the sample.
Manage the dust.
Discuss cyclone-assisted collection to help reduce sample loss and dust exposure during crushing. Retrofit options are listed for BB 50, BB 250, BB 400 and BB 500; confirm the setup for BB 250.
A BB 250 / DM 200 combination can connect crushing and disc milling through a cyclone system for continuous sample preparation.
Discuss cyclone compatibilityPRESSURE. MOVEMENT. CONTROL.
Start with the feed.
Control the gap.
Material enters through the hopper into a wedge-shaped chamber. One jaw is fixed while the other moves, applying pressure to reduce the sample. Particles pass to the collector when small enough to move through the discharge gap.
Watch the jaw-crushing principleRETSCH animation illustrates the principle using the BB 100.
Match the feed.
Check maximum dimensions, hardness, brittleness and the material’s breaking behavior.
Set the reduction.
Choose a model, jaw material and gap suited to the required result.
Validate the output.
Assess the size distribution, recovery, wear and throughput with representative material.
TYPICAL MATERIALS
