With both materials, exposure to changing temperatures, rain, snow, sleet and other weather conditions gradually wears on the surface of the construction, producing flakes in the process. Both brick and concrete spalling take place in just about any type of climate, although the rate of flaking is accelerated in areas where weather conditions are particularly harsh for most of the calendar year.

Ball valves are shutoff valves that use a ball to stop or start the flow of fluid downstream of the valve. The ball, shown in Figure 7-1 , performs the same function as the disc in other valves. As the valve handle is turned to open the valve, the ball rotates to a point where part or the entire hole that is machined through the ball is in line with the valve body inlet and outlet.

Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
