The Jaw Crusher BB 400 is specifically designed for accepting large feed sizes up to 220 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 50. A throughput of up to 400 kg/h is possible with the BB 400.
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.

- Selection of hoppers for specific applications
Çeneli kırıcı BB 400 Superiority in detail
For sample amounts up to 10 l, the BB 400 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 BB 400 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 5 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.

Breaking jaws
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:
- Manganez çelik
- Paslanmaz çelik
- Tungsten karbür
- Ağır metal içermeyen öğütme için çelik
- Paslanmaz çelik 316L
- NiHard4 Çelik
Hazne Türleri
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.
Collecting vessels
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.

Çeneli kırıcı BB 400 Fonksiyon prensibi
Çeneli Kırıcı BB 400, sağlam ve güçlü bir zorunlu beslemeli kırıcıdır. Besleme malzemesi geri tepmesiz huniden geçer ve kırma odasına girer.
Sabit kırma kolu ile eksantrik bir tahrik mili tarafından hareket ettirilen kırma kolu arasındaki kama şeklindeki alanda boyut küçültme gerçekleşir. Eliptik hareket, yerçekimi altında kırma aralığına doğru hareket ettirilen numuneyi ezer.
Numune, boşaltma boşluğu genişliğinden daha küçük olur olmaz, çeneli kırıcı içindeki çıkarılabilir bir toplayıcıya düşer. Ölçekli sürekli boşluk genişliği ayarı, ayarlanan boşluk genişliğine göre optimum boyut küçültme sağlar.

Green Cement - Innovation in the Construction Industry
Green Cement represents a significant innovation in the construction industry, aimed at reducing environmental impact and promoting sustainable development. Traditional cement production is a major contributor to global CO emissions, accounting for approximately 7-8% of the total. With this material these emissions can be minimized by incorporating supplementary cementitious materials (SCMs) such as fly ash, slag and seashell by using alternative fuels and raw materials. Our solutions enable the production of a more sustainable product with high performance characteristics and exceptional physical properties.
