Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
Sometimes, single side grinding is preferable over surface grinding, because it has the ability to produce flat surfaces. However, the manufacturing cost is still high because of the high tool wear and long machining time. Additionally, most of these grinding processes are followed by a lapping process.
Crushing plants are of great interest in reducing a particle size of rocks and ores as milling operations need to consider sustainable development. Since the crushing plants operate …
The desired particle size of determines the number of stages of crushing (primary, secondary and tertiary) and the type of machine to be used. The quantity of material entering the crusher determines the size of the machine selected. The type of crushing or grinding method also impacts the way in which the rock is broken during crushing or ...
