Sammanfattning
This thesis experimentally and theoretically investigated the integration of waste
heat for drying of rock particles during milling, as well as the potential drying effect
of heated airflows inside of Comminution Reimagined’s ARBS mill. Pre-study tests
indicate that a cost effective side effect, drying of the crushed particles, occurs when
heat is added to the air system that extracts fine crushed rock particles. The drying
of crushed particles is key in order to improve crushing performance and fines extraction.
Previous research has left several knowledge gaps, mainly in terms of how
the drying effect can be controlled and predicted, i.e. the drying parameters.
Experimental data was used together with a broad literature study to gain an understanding
of the drying effect and parameters as. A conceptual design was created
to illustrate a potential integration of the drying system for the current design of the
rock crushing mill. Our findings indicate that integrating waste heat into the rock
crushing mill can be done in an efficient way where the negative effects of moist rock
particles inside of the ARBS mill can be minimised, but requires further research
before implementation.
