Experiments in mechanical processes I (complex practical course)

1. crushing of dispersed bulk materials in the jaw crusher with subsequent sieve analysis

• Investigation of the crushing behaviour of different materials in the jaw crusher
• Application of sample division, comminution and sieve classification

2nd bond attempt

• Energetic consideration of the shredding process
• Determination of grindability according to BOND by determining the labour index

3. particle size analysis using a laser granulometer

• Particle size analyses of various materials with the laser granulometer in wet and dry areas
• Comparison of the analysis methods sieving/laser granulometer

4. investigations into the separation behaviour in an air classifier

• Dependence of the separation quality on the settling speed and the load
