Jaw Crushers BB 100 / BB 200 / BB 300
The powerful RETSCH Jaw Crushers are designed for the rapid, gentle coarse and primary crushing of hard, brittle and tough materials. The breaking jaws are available in a variety of materials which include heavy-metal-free steel. Their efficiency and safety makes these pulverizers ideal for sample preparation in laboratories and industrial plants.

Four basic models are available: from the compact bench-top model BB 50 to the biggest floor model, BB 300 which allows for feed sizes up to 130 mm. RETSCH jaw crushers combine increased operating convenience with maximum working safety.

Main areas of application

Cement clinker, coal, construction materials, granite, metal alloys, quartz, ores, oxide ceramics, silicon, slag, tungsten alloys

  • Powerful size reduction with high throughput
  • high final fineness (down to d90 < 2 mm)
  • Wear compensation due to zero point adjustment
  • batch-wise and continuous operation
  • Wide selection of breaking jaw materials
  • Safe and simple handling and cleaning

Jaw Crusher BB 51
The BB 51 jaw crusher is particularly useful in reducing small sample volumes with large feed sizes down to < 0.5 mm in one easy step. Samples such as stone, minerals, ores, glass, synthetic resins and many other hard or brittle substances are ground without contamination, using grinding tools of manganese steel, stain- less steel, wear-resistant tungsten carbide, zirconium oxide or heavy metal-free steel. The grind size is controlled through digital gap width setting. The BB 50 features a zero-point-adjustment to compensate for wear and assure reproducible samples at all times. With its small footprint and dust-tight housing, this unique jaw crusher easily fits on any laboratory bench.

Main areas of application

Motic Advanced 3.2
Giving wider and deeper insights of the sample, the Motic advanced software 3.2 is a combination of Motic Image analysis 2.0 and many more features like 3-dimensional imaging, Multi Focus ,Image assembly, segmentation. Use this software package to analyze fluorescence images and segment images by RGB or Gray Scale.
Motic Multi-focus
allows you to get around the difficulty by combining images taken at different focal depths into a single focused image.
Motic Assembly
allows you to stitch together a single large image from several images.
Pharma Pro
Improving science and making the planet a healthier place demands a blend of accurate & reliable results to make a difference. Accurately measure the size and shape of your particles with the Pharma pro software plugged to Motic polarizing microscope. This helps generate reports with specific particle details like; area, aspect ratio, length, perimeter, roundness, shape, sphere volume, width and also determines number of particles falling in the same range.
