Factors Determining Lumber Recovery in Sawmilling

diameter 16-foot-long log is 0.240 inch for a mill cutting dimension lumber (fig. 4a). If the kerf on this log is reduced to 0.180 inch, the pattern shift results in a 2 by 6 rather than a 2 by 4, with an increase in lumber yield from 64 to 69-1/3 board feet–an 8.3 …


Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Optimization of mill performance by using

The performance of tumbling mills is sensitive to the volumetric mill filling which influences grinding media wear rates, throughput, power draw, and product grind size from the circuit. Each of these performance parameters peaks at different filling values. In order to contin-uously optimize mill operation, it is vital to


Size Reduction and Energy Requirement - ScienceDirect

A Bond ball mill work index is then performed on the mill product for the design of SAG-ball mill circuits. This is important because it was found that there was a 1–1.5 kWh/t higher ball mill work index if the –3.35 mm ball mill test feed size is obtained by SAG mill grinding compared with crushing.
