RETSCH / POWER & FINAL FINENESS

BB 500.
Powerful reduction. A finer endpoint.

A floor-standing jaw crusher that combines feed below 110 mm with a published final fineness of 90% below 0.5 mm. Throughput can reach 500 kg/h, depending on the material and settings.

RETSCH BB 500 Jaw Crusher for crushing hard, brittle samples

Explore the equipment and access details.

FEED SIZE*< 110 mm

FINAL FINENESS*90% < 0.5 mm

THROUGHPUT*500 kg/h

THE MODEL IN FOCUS

Finer output in one working run.

Emphasize final fineness

A steep crushing chamber and high-frequency jaw movement support a published result of 90% below 0.5 mm in one working run.

Use both sides of the jaws

The breaking jaws can be rotated 180° to use both sides. Discuss manganese steel and NiHard 4 around wear and sample requirements.

Connect to the workflow

A 15 L collector supports batch work. Dust extraction and optional process-line configurations help connect crushing to the surrounding process.

*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 500 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 500: manganese steel, NiHard 4. 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 15 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.

Jaw rotation & maintenance planning

The BB 500 jaws can be rotated 180° to use both sides. Review wear patterns, inspection and service requirements with the team and the operating instructions.

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 500.

Discuss cyclone compatibility

PRESSURE. 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 principle

RETSCH 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.
