Челюстна трошачка BB 200

The BB 200 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.
  
  
• 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.
