AT A GLANCE
Find the right balance.
The finest output, largest feed and highest throughput belong to different models.

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 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.
THE MATERIAL MATTERS
Choose the jaws.
Protect the analysis.
Jaw and wear-plate materials affect abrasion, service life and the substances introduced into a sample. Compare the actual materials offered for each model with your analytical requirements.
- Starting feed geometry and target size distribution
- Batch quantity or required continuous throughput
- Wear, contamination limits and cleaning requirements
- Collection, dust handling and downstream equipment
SELECT A MODEL. PROVE THE RESULT.
Your feed.
Your next decision.
Share the starting size, target result, material and required capacity. Discuss feasibility testing, jaw materials and a configuration suited to the workflow.
