Longitudinal studies and crosssectional studies are two different types of research design. In a crosssectional study you collect data from a population at a specific point in time; in a longitudinal study you repeatedly collect data from the same sample over an extended period of time. Longitudinal study.

Attrition mills effectively mill metals in inert atmospheres, such as in solidstate or mechanical alloying processes, but are not cost effective. Product output is relatively low with attrition mills, compared to large tumbler and vibratory ball mills. Consequently, tumbler ball mills usually are used for production runs of over 135 to 180 kg ...

Revolved Cross Section. A revolved view is a cross section of an existing view that is revolved 90 degrees around a cutting plane projection. You can use a cross section created in the 3D model as the cutting plane, or you can create one on the fly while placing the view. The revolved view differs from a crosssection view in that it includes a ...

When sketching an object or part that requires a sectional view, they are drawn by eye at an angle of approximately 45 degrees, and are spaced about 1/8" apart. Since they are used to set off a section, they must be drawn with care. It is best to use the symbol for the material being shown as a section on a sketch.

A crosssection view of a compression seal. In geometry and science, a cross section is the nonempty intersection of a solid body in threedimensional space with a plane, or the analog in higherdimensional spaces. Cutting an object into slices creates many parallel crosssections. The boundary of a crosssection in threedimensional space that is parallel to two of the axes, that is ...

A concept which has found some application for ball mills is the "angular spiral lining". The circular crosssection of a conventional mill is changed to a square crosssection with rounded corners by the addition of rubberlined, flanged frames, which are offset to spiral in a direction opposite to the mill rotation.

The crosssectional area is a geometric property of structural elements such as beams, columns, slabs, etc. and it is used to calculate the axial stresses in Crosssections. In general it can be said that the greater the dimensions of a crosssection under a given load, the greater the Crosssectional area and the smaller the axial stress.

Ball Mills. The ore from the crushing section is delivered to the fine ore bin placed at the head of the grinding section, from which it is fed, together with water, to one or more grinding units consisting of a ball mill or rod mill in circuit with a classifier. One such unit with a conical ball mill is shown in Fig. 9.
