Using the Bond work index to measure operating

Introduction Comminution efficiency as measured by relating circuit performance to the consumption of energy and the time and money required can be determined by the following comparisons Theoretical efficiency The theoretical efficiency is the actual energy consumed in a comminution machine compared to the theoretical energy


of grindability has enjoyed a wide acceptance it will be used in the description of the grindability influence In the statement of the model in the form of Eq 4 the comminution coefficient is a multi functioned variable To include the grindability influence in the model it is necessary to extract the desired functionality and redefine

Hardening and tempering of knife steel — Materials

To reduce the brittleness the material is tempered usually by heating it to 175 350°C 347 662°F for 2 hours which results in a hardness of 53 63 HRC and a good balance between sharpness retention grindability and toughness Tempering should be carried out within a reasonable time after hardening preferably within an hour or so
