Recovery of the thermal energy is not simple since the temperature range of the 7 grinding mills studied ranges from 18oC to 38oC This is a difficult energy source to recover because of the low temperatures involved For these reasons a logical extension of this project would be to carry out a literature survey on technologies for lowgrade.
