Knowing the difference between parametric and nonparametric test will help you chose the best test for your research. A statistical test, in which specific assumptions are made about the population parameter is known as parametric test. A statistical test used in the case of nonmetric independent variables, is called nonparametric test.
Apr 24 2015 Ball mill consist of a hollow cylindrical shell rotating about its axis Axis of the shell horizontal or at small angle to the horizontal It is partially filled with balls made up of SteelStainless steel or rubber Inner surface of the shell is lined with abrasion resistant materials such as ManganeseSteel or rubber Length of the mill is approximately equal to its diameter Balls occupy about 3050 of the
Ball mill One can increase the weight of the charge by increasing the number of balls or by using a ball material of high density. the ball mill should be operated at a speed that is optimum speed equal to 50 to 75 percent of the critical speed the operating speed must be less than the critical speed.
2012312 chine tool can be produced on a computer numerical control machine tool, with its many advantages. The machine tool movements used in producing a product are of two basic types pointtopoint straightline movements and continuous path contouring movements.
