Universal Continuing Decision Process For: Case Study *
| At the Hope Valley (England) Cement Works, in the mill house where limestone clinker is milled into cement, at normal temperatures of 2200°F, the elevators transport finished cement at rates of 200 tons/hour. Entrained in the cement are small numbers of nibs milling medium (17mm manganese balls), These are removed at the head of the elevator, where the cement enters a centrifugal separator, via a nib trap, where the nibs are extracted from the flow of cement. The collected nibs are conveyed through an air slide incorporating an AKO pinch valve. |
