2020-3-12 PROBLEMS WITH CONVENTION GRINDING. 6.1 Loss of etheric oil. The applied energy gets dissipated in the form of heat (>99%) and hence the temperature in the grinding zone rises to more than 90oC resulting in loss of etheric oils whose boiling point vary from 50oC to 320oC. This results in the inferior quality of the ground product.
