Types of Crushers Explained: Everything You Need to Know
Impact crushers are the secondary crushers or the tertiary crushers that use high speed impact forces to break the materials. They are a set of rotors with hammers or blow bars mounted on them that crush the material as it enters the crushing chamber. This phenomenon results in the material to be cracked and fragmented into smaller pieces.
Moisture in Coal
Moisture absorbs heat, so high moisture content in coal reduces the relative efficiency of heating when a coal is combusted. This is why low-rank, high-moisture coals have lower calorific values (Btu/lb) than high-rank, low-moisture coals. Moisture adds weight to coal, and also contributes to spontaneous combustion in low …
Tribo-electrostatic separation of high ash coking coal …
The effect of moisture on tribo-electrostatic separation of reject coking coal is shown in Fig. 5 (a–d) at applied voltages of 10, 15, 20, and 25 kV respectively. The figures demonstrate the influence of humidity in the range of 10 to 50% of RH on ash and yield of the particles collected in different bins.
