Taal:

The BB 50 is the smallest model of the RETSCH jaw crusher series and has been specially designed for sample preparation in the laboratory. The compact machine fits on any laboratory bench and offers safe and convenient handling.

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.

Kaakbreker BB 50 Superiority in detail

The BB 50 is designed for efficient and convenient size reduction. The variable speed can be set between 550 and 950 min-1 to adapt the crushing process to sample requirements. The possibility to reverse the rotating direction is helpful if too much sample material has been fed to the crusher causing it to block. The simple push of a button restarts the process. Due to permanently lubricated bearings and its solid design, the BB 50 jaw crusher is virtually maintenance-free.

Kaakbreker BB 50 Zero Point Adjustment

An advantage of the jaw crusher BB 50 is the so-called zero point adjustment. Sooner or later, the breaking jaws will show signs of wear which will affect the reproducibility of the size reduction process. This effect can be compensated by adjusting the zero point. A sign in the display indicates if the jaws need to be replaced altogether, thus helping to avoid damages to the crusher.

Kaakbreker BB 50 Easy operation & cleaning

Working with the BB 50 jaw crusher is easy and safe. The large, clearly structured operating panel allows for digital display of parameters such as gap width and speed. The sample material is conveniently fed to the crusher via the large hopper equipped with splash-back protection.

For easy cleaning the fold-back hopper and crusher arm can be removed without using tools. The user can also exchange the breaking jaws if the crusher needs to be converted for different applications.

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:

  • mangaanstaal
  • roestvrij staal
  • wolfraamcarbide
  • zirkoniumoxide
  • staal voor het malen zonder zware metalen

The optional lid for the collecting receptacle of the jaw crusher ensures that the fine residues from previous samples fall on the lid and not into the receptacle which helps to avoid cross contaminations.

Kaakbreker BB 50 Principe

De kaakbreker BB 50 is een robuuste, performante breker. Het produkt valt door de toevoertrechter, die tegen terugspringend produkt beveiligd is, in de trechtervormige maalkamer.

Daar wordt het materiaal gebroken tussen de ellipsvormig bewegende en de vaststaande arm en naar beneden toe bewogen.

Zodra de deeltjes een fijnheid hebben bereikt die kleiner is dan de onderste opening, vallen ze in een uitneembare opvanglade. De traploos instelbare spleetinstelling kan worden afgelezen op een digitale display en garandeert daarbij een optimale, aan het te malen produkt aangepaste instelling.
