The Jaw Crusher BB 300 is specifically designed for accepting large feed sizes up to 130 mm. The gap width can be set stepless from 1-40 mm. Depending on the sample material, particle sizes down to 5 mm can be obtained, resulting in a crushing ratio of 26. A throughput of up to 600 kg/h is possible with the BB 300.
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.
Versatile unit with a focus on feed size
Robust design, simple handling and cleaning are the features of the BB 300 jaw crusher. For sample amounts of up to 35 L the BB 300 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. The BB 300 jaw crusher features maintenance- & lubricant-free sliding bearings.
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.
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.
Breaking jaws and wearing plates are available in five different materials to be selected depending on the sample and the analysis to be carried out:
Apart from the standard model, the BB 300 jaw crusher is also available in special version adapted to particular application requirements.
Heavy-metal free crushing
All jaw crushers are available in a heavy-metal-free version.The BB 300 can also b e supplied in a special version suitable for crushing semiconductor materials. This includes plastic lining of feed hopper and receptacle as well as breaking jaws and wear plates of tungsten carbide.
Thus, the sample does not come into contact with metal materials at any point and no abrasion of the grinding tools impairs the purity of the sample material.
Process-line version
The BB 300 jaw crusher is also available in versions which are suitable for continuous size reduction in online operation, e. g. for quality control during the production process.
These are supplied without feed hopper and motor protection switch. The voltage of the three-phase AC motor will be selected in accordance with the customer's requirements.
RETSCH’s powerful jaw crushers are ideally suited for preliminary crushing of construction materials, ores, granite, oxide ceramics, quartz, slag, silicon, coal, tungsten alloys, cement clinker, etc.

조 크러셔 BB 300은 견고하며 강력한 강제 투입식 분쇄기입니다. 투입 시료는 no-rebound 투입구를 통해 분쇄실로 들어갑니다. 분쇄는 고정 분쇄 arm과 편심 구동축에 의해 움직이는 arm 사이의 쐐기형 구역에서 발생됩니다. 타원 운동이 중력에 의해 낙하하는 시료를 분쇄합니다.
이후 배출 간격보다 작아진 시료가 수집 용기로 낙하합니다. 스케일을 활용한 연속 간격 조절은 설정 간격에 따라 최적화된 분쇄를 보장합니다.
