Retsch Jaw Crusher BB 100
The Jaw Crusher BB 100 is the smallest floor model of the series. It accepts feed sizes up to 50 mm. The gap width can be set stepless from 0-20 mm. Depending on the sample material, particle sizes down to 4 mm can be obtained, resulting in a crushing ratio of 12.5.
The RETSCH jaw crusher series is available in 8 different sizes. Throughput and final fineness depend on the crusher type, selected gap width and breaking properties of the sample material.
Robust design, simple handling and cleaning are the features of the RETSCH jaw crusher models. Small amounts of sample are processed batchwise; for larger amounts the crushers can be operated continuously.
SUPERIORITY IN DETAIL
Robust design, simple handling and cleaning are the features of the BB 100 jaw crusher. For small sample amounts of up to 2 L the BB 100 can be used batch-wise; for larger amounts it can be operated continuously.
The crushed sample is collected in a removable collector. For larger amounts or continuous crushing operations, the sample collector can be replaced by customer-specific solutions (e.g. a belt conveyor).
A Belleville spring washer integrated in the spindle adjustment provides additional overload protection. The eccentric spindle which moves the crushing arm is driven by a robust brake motor via V-belts. The largest belt pulley also acts as the flywheel to ensure uniform and smooth operation of the jaw crusher.
WEAR COMPENSATION BY ZERO-POINT ADJUSTMENT
Depending on the material and the throughput, sooner or later the breaking jaws will start to show signs of wear. This means that the set breaking jaw distance or the crushing gap will increase with time. To still be able to obtain reproducible crushing results this wear must be compensated.
RETSCH jaw crushers can be continuously adjusted, allowing for compensation of breaking jaw wear. This is done by slowly altering the gap width setting with the motor running until the breaking jaws are heard to come into contact. The new zero point thus obtained is saved by readjusting the scale.
USER CONVENIENCE COMBINED WITH MAXIMUM SAFETY
Safety is a top priority with RETSCH jaw crushers. The feed hopper with splash-back protection cannot be accessed by hand. A safety switch and the brake motor ensure an immediate stop if the unit is opened or switched on incorrectly.
For easy cleaning of the crushing chamber, the hinged hopper can be removed in a few simple steps. The jaw crushers run very smoothly and quietly and are virtually maintenance-free.
