The Jaw Crusher BB 250 is specifically designed for accepting large feed sizes up to 120 x 90 mm. The gap width can be set stepless from 0-30 mm. Depending on the sample material, particle sizes down to 2 mm can be obtained, resulting in a crushing ratio of 45. A throughput of up to 300 kg/h is possible with the BB 250.
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.

Model with most ergonomic handling
For sample amounts up to 10 l, the Jaw Crusher BB 250 is used batchwise; for larger volumes it can be operated continuously. Thanks to the modular concept of the housing and frame, this jaw crusher is suitable for a wide range of applications.
A front door gives direct access to the crushing chamber at a perfect height for ergonomic and easy cleaning. The feed hopper with splash-back protection can be removed quickly and easily. The Jaw Crusher BB 250 has a connection for dust extraction and is protected against mechanical overload. A scale indicates the wear of the breaking jaws, informing the user when it is time for an exchange.
The crushing chamber is available in 6 different materials to ensure neutral-to-analysis sample preparation. The technical and safety features make this jaw crusher ideally suited for sample preparation in laboratories and for small scale production.
Front door allows for easy cleaning
Connection for dust extraction
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:
Three hopper types are available for the BB 250 jaw crusher.
The standard hopper can be optionally equipped with a special infeed hopper. This additional hopper can be placed on a table for loading up to 10 l of sample material. By attaching it to the standard hopper with a connection rod, the sample is fed into the BB 250 with the help of a manual pusher.
A special hopper is available for quick and easy feeding of drill cores or large amounts of bulk material. The cover can be closed to serve as splash back protection.
In addition to the standard receptacle which accepts sample amounts up to 10 l, two options are available.
For continuous operation the collection funnel with outlet is the ideal choice.
The large volume receptacle accepts up to 26 liter of sample and comes with a flexible connection flange and a carrier on wheels. This version is the best choice for dust-free operation.
With the Jaw Crusher and Sample Divider Combination Unit ABP, the sample is first crushed in a BB 250 and then automatically divided into 8 equal part samples.
This automated procedure helps to avoid manual mistakes and ensures a high degree of reproducibility.
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.

Jaw Crusher BB 250은 견고하고 강력한 강제 투입 분쇄기 입니다. 투입 시료는 역 분사 방지 투입구를 통과해 분쇄실로 들어가게 됩니다.
분쇄는는 고정된 분쇄 암과 편심 구동축에 의해 움직이는 분쇄암 사이 쐐기 모양의 영역에서 발생합니다. 타원 운동은 중력에 의해 떨어지는 시료를 분쇄합니다.
시료는 즉시 작아지고 분쇄 간극으로 배출되어 탈착 가능한 용기에 수집됩니다. 눈금을 통한 연속 간격 설정은 설정 간격에 대한 최적의 입도 축소를 보증합니다.
