impact evaluations – that is, evaluations that provide information about the intended and unintended long-term effects produced by programmes or policies. Impact evaluations need to go beyond assessing the size of the effects (i.e., the average impact) to identify for whom and in what ways a programme or policy has been successful.

Mills usually produce a patent, first clear, and second clear flour, or a combination of these. Determine the percent contribution each flour makes to the total flour output.

Sawmills usually plane dimensional lumber to specific sizes and smoothness standards. For instance, a rough-cut 2×4 coming from a head rig is exactly that nominal size — 2 inches thick by 4 inches wide. But, a 2×4 exiting a sawmill's downstream planer actually measures 1-1/2 inches by 3-1/2 inches finished size.

Hammermill tip speed adjustment alters particle size without downtime. Particle size range for a hammermill screen size can be adjusted through manipulation of the hammer tip speed, which is made possible by the use of motor variable frequency drives. The hammermill is a cost-effective method of reducing particle sizes of grains for feeding.
