mill performance. This had been hidden previously by the regular changing of liners over a number of mills in the older plants that had many mills in parallel. In fact this is generally still the case in the multi-stream plants, where mill liner design and selection is only tackled on a cost consumables basis.

Small wind turbine power generation systems have the potential to meet the electricity demand of the residential sector in developing countries. However, due to their exposure to low Reynolds number (Re) flow conditions and associated problems, specific airfoils are required for the design of their blades. In this research, XFOIL was used to develop and test three high performance …

To properly conduct a micro-siting of an orthopter-type vertical axis wind turbine (O-VAWT) in the built environment, this study investigated the effects of horizontal shear flow on the power performance characteristics of an O-VAWT by performing wind tunnel experiments and computational fluid dynamics (CFD) simulations. A uniform flow and two types of shear flow …

The main factors affecting the working performance of the hammer mill are divided into three categories: the crushed material, the crusher itself and the supporting equipment. 1.Influence of crushed material. Different kinds of raw materials, the seed structure and physical properties will be a certain difference, the difficulty of crushing ...

This work chose the ball mill and vertical roller mill, two common grinding instruments, to grind the blast furnace slag from the same source and same batch. The particle morphology, particle size distribution (PSD) characteristics and powder characteristics of the two types of processed slag were compared and studied.
