"small" from "medium" and "large" mills. Sawmills of the United States range from 3,000 to 300,000 board feet in 8-hour produc-tion capacity. For purposes of this bulletin, producing up to 20,000 board feet per 8-shift have been classified as small. This dividing line is low for certain west coast mills ; elsewhere in theUnited States, ma-

The speed of sound is typically measured in meters per second or feet per second. Speed increases as the density of the medium increases and its elasticity decreases. For example: In air, the speed of sound is approximately 344 meters per second (1,130 feet per second) at standard temperature and pressure.

The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are de-scaled after exiting the furnace, and then proceed through a five stand roughing mill, a six stand intermediate mill, and an eight stand finishing mill. Dimensional control is maintained by optical laser gauges and manual micrometer checks.

Figure 6: Torque-vs.-speed diagram of the IM (5) There are only limited control possibilities for grid-connected induction motors. The slip-ring rotor allows the connection of external resistors to the rotor circuit. The dependence of torque-speed characteristics on rotor resistance is shown in Figure 7.

Hammer mills are used in particular if the application demands a precise particle reduction for hard-to-mill active ingredients and other substances. In addition, hammer mills are used to remill fragmented tablets. Tablets that have already been produced undergo inspection and may fail to meet the customer's requirements for various reasons.
