Jaw Crusher BB 50

Selection help
The BB 50 is available with different breaking jaw and wearing plate materials which allows for contamination-free crushing without undesired material abrasion.

Please note:

The material of the crushing tools should be harder than the sample to be crushed.

For further information on materials, please see the document "Material Composition of Equipment and Accessories" at the end of the order data list.

  • Manganese steel (density 7.8 g/cm3; hardness 35 HRC):
    Used for crushing medium-hard to hard and brittle sample materials. As manganese steel is compacted under pressure, the material becomes harder over time. 

  • Stainless steel (density 7.8 g/cm3; hardness 550 HV):
    Used for crushing medium-hard to hard, brittle, non-corrosive sample materials. 

  • Tungsten carbide (density 14.8 g/cm3; hardness 1200 HV):
    Used for crushing very hard, brittle sample materials (with a Mohs-hardness up to 7-8). By using tungsten carbide, contamination of the sample with iron is prevented.

  • Zirconium oxide (density 5.9 g/cm3; hardness 1200 HV, high abrasion resistance):
    This ceramic material is suitable for crushing medium-hard to hard or fibrous sample materials. It is mainly used for heavy-metal-free grinding processes, but also when discoloration of the sample by abrasion must be avoided. Please bear in mind that zirconium oxide is a brittle material which may break under too much stress.
     
  • Steel 1.1750/1.0344 (density 7.8 g/cm3; hardness 52-60 HRC):
    Mainly used for crushing medium-hard to hard and brittle sample materials. For heavy-metal-free sample homogenization.
