The technique called section views is a very important aspect of design and documentation. It is used to improve the visualization and clarity of new designs, clarify multiview drawings, reveal interior features of parts, and facilitate the dimensioning of drawings. For mechanical drawings section views are used to reveal interior features of an object when hidden lines cannot properly ...

Type of other Mill (Tube Mills) BALL TUBE MILL The Ball Tube Mill is basically horizontal cylindrical tube rotating at low speed on its axis, whose length is slightly more to its diameter. The inside of the Cylinder shell is fitted with heavy cast liners and is filled with cast or forged balls for grinding, to approximately 1/3 of the diameter.

Cross Section. C ross section means the representation of the intersection of an object by a plane along its axis. A crosssection is a shape that is yielded from a solid (eg. cone, cylinder, sphere) when cut by a plane. For example, a cylindershaped object is cut by a plane parallel to its base; then the resultant crosssection will be a circle.

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.

Rolling schematic view Rolling visualization. In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of is classified according to the temperature of the metal rolled.
