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.

Connection for dust extraction
Fălcile și placuțele de uzură sunt disponibile în 5 materiale diferite și pot fi selectate în funcție de caracteristicile probei și de analizele efectuate ulterior măcinării:
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.
Concasoarele puternice RETSCH sunt ideale pentru măcinarea primară a materialelor de construcții, a minereurilor, granitului, ceramicii de oxid, cuarțului, zgurii, siliciului, cărbunelui, aliajelor de tungsten, clincherului de ciment, etc.

Concasorul cu fălci BB 250 este un concasor robust și puternic, cu alimentare forțată. Materialul alimentat trece prin buncărul de alimentare fără recul și intră în camera de zdrobire.
Reducerea dimensiunilor are loc în zona trapezoidală intre falca fixa de cea acționata printr-un excentric. Mișcarea eliptică zdrobește proba care apoi cade sub forța gravitației.
Îndată ce proba este mai mică decât dimensiunea spațiului de evacuare, cade într-un vas colector detașabil. Dimensiune spatiului de evacuare poate fi ajustata continuu, ceea ce conduce la o reducere optima a probei.
