turbines include vertical axis or horizontal axis wind turbines. The turbines are classified upon how the shaft of the generator is mounted. The horizontal axis wind turbine HAWT was invented before the vertical axis wind turbine (VAWT), which led to its popularity and wide use. Figure 1.2 shows a diagram of these two types of systems.

The end milling is the operation of producing a flat surface which may be vertical, horizontal or at an angle in reference to the table surface. The cutter used is an end mill. The end milling cutters are also used for the production of slots, grooves or keyways. A vertical milling machine is more suitable for end milling operation.

The tower mill is a robust, proven technology invented in the 1950s and supported by hundreds of installations in mineral concentrators worldwide. The major design feature of the tower mill is a central agitator screw, the only moving machine component in contact with the slurry and steel media, which allows size reduction by attrition.

Difficulties in the starting of vertical turbines have also hampered development, believed until recently to be incapable of self-starting [2]. However, the VAWT requires no additional mechanism to face the wind and heavy generator equipment can be mounted on the ground, thus reducing tower loads. Therefore, the VAWT is not completely

Milling Machine Definition: The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter.The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the operations can be performed on it with high accuracy.

Vertical windmill generators work straightforwardly. It spins on a vertical axis to capture the wind. However, it has different starting speeds and rotations per minute rating. It varies from one model to another and depending on the power output that one can generate. These vertical wind turbines are with different colors, sizes, and shapes, too.

Tower - The mast supporting the windmill. Trailing edge - The blade edge furthest from the leading edge. The trailing edge is sharpened, so as to release the passing air without turbulence. Wedges - Tapered pieces of wood used to build up the blade thickness and increase its angle to the wind near the root.

Tower mill – Strong and tall windmill whose body is created from masonry, with adjustable top cap that could be rotated so that it rotating fan can take best advantage from current wind condition (although some were made with fixed tops). Because of the strength of the structure, blades of tower mills were able to be much wider and taller.

the tower. Of course wind turbines must be designed as a system, and so rotor design affects drivetrain design which affects control system design, etc. and so no component of a wind turbine can be considered in isolation. In general small wind turbines should be designed to IEC61400-2, Design Requirements for Small Wind Turbines [ 2 ].

between vertical mills and ball mills arises from differences in the frequency and energy intensity of ball collisions. The higher efficiency of the vertical mills is due to the higher frequency of lower energy impacts and, by the same token, lower frequency of higher energy impacts when compared to conventional ball mills (Mazzinghy et al., 2013).
