furnace slag can be added at the grinding stage. The mill control can be opti-mized based on predicted quality parameters, which in turn reduce energy consumption and improve the cost-effectiveness and availability of the plant and the quality of the product. The Rohrdorf plant has four ball mills with a total grinding capacity of around 270 t/h.
Jun 02, 2008 · There are two generally accepted reasons why manufacturers measure roundness of components. The first is to sort nonconforming parts based on a customer-supplied blueprint before shipment to the customer; the second is to control the process tool with immediate feedback. Controlling the process tool ...

Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can

Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached ...

Critical process parameters (CPP) in pharmaceutical manufacturing are key variables affecting the production process. CPPs are attributes that are monitored to detect deviations in standardized production operations and product output quality or changes in Critical Quality Attributes.Those attributes with a higher impact on CQAs should be prioritized and held in a stricter state of control.
