언어:

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. 

조 크러셔 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.

호퍼 유형

Three hopper types are available for the BB 400 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 400 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.

조 크러셔 BB 400 은 견고하고 강력한 강제 투입식 분쇄기입니다. 투입 시료는 역 분사 방지 투입구를 지나 분쇄실로 들어갑니다.

분쇄는 고정 분쇄 암과 편심 구동축 샤프트에 움직이는 암 사이 쐐기 모양의 영역에서 발생합니다. 암의 타원형 운동이 중력에 의해 분쇄 간격으로 이동하는 시료를 분쇄합니다.

이 후 시료가 배출 간격보다 작아지면 수집 용기로 떨어집니다. 눈금을 사용한 연속적 간격 설정으로 선택된 간격에 따라 최적의 분쇄를 보장합니다.
