Ball clay is extracted from the ground by surface working (open pit method), underground mining having ceased in 1999. Extraction involves excavators and dump trucks to selectively remove individual grades of clay to storage and blending facilities. The ratio of waste to clay is variable, but overall is in the order of 1 to 1.5.

Defense is where Gillispie shines. His teams play an aggressive, in-your-face style that puts pressure on ball-handlers and forces turnovers. TSU ranked 11th nationally in defensive TO rate last year, which helped make up for their poor defensive rebounding and allowance of one of the highest 3PA rates in the country.

• Clay – wash 50g of sample sand with alkaline water (NaOH) to remove clay, dry the sand and weighed to find the clay content • Permiability – measure of escape gases – done by standard ramming of sand and passing air through it at known pressure. Pressure loss between orifice and sand gives permiability (12-9)

Flow Control Valves. Cla-Val Flow Control/Rate of Flow Control Valves prevent excessive flow by limiting flow to a preselected maximum rate, regardless of changing line pressure. The pilot control responds to the differential pressure produced across an orifice plate installed downstream of the valve. Accurate control is achieved as very small ...
