Fragmentation energy calculation model of coal …
Impact crushing tests The impact crushing test of coal was conducted in laboratory to get the crushed coal particles. The impact load was achieved by a drop weight system as shown in Figure 2. The drop weight with 73.35 kg was released from a height of 2.5 m, which can accelerate the drop weight maximum to 7 m/s.
