Understanding Rolling Process in Long Product Rolling Mill. A wire rod rolling mill, for example, gradually reduces the crosssectional area of a starting billet (, 150 mm square, 1012 meters long) down to a finished rod (as small as mm in diameter, km long) at high finishing speeds (up to 120 m/sec).
The index head and footstock attach to the worktable of the milling machine by Tslot bolts. An index plate containing graduations is used to control the rotation of the index head spindle. The plate is fixed to the index head, and an index crank, connected to the index head spindle by a worm gear and shaft.

Function Principle. In a drum mill the sample (usually precrushed material) is placed inside the drum with the grinding media (grinding balls or rods) and subjected to external forces. The Ball Mill and Rod Mill Modules are used for fine grinding of solid matter by impact and friction, in wet or dry condition.
Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles.  But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball .
Connecting Rod. A connecting rod is an engine component that transfers motion from the piston to the crankshaft and functions as a lever arm. Connecting rods are commonly made from cast aluminum alloy and are designed to withstand dynamic stresses from combustion and piston movement.
Linear ball mill grinding uses a linear model of balance and substitution for the real distribution for the time of grain processing inside the mill, which is a combination of ideal extrusion and ideal mixing. Applications. Milling and grinding media are designed and manufactured to .
Finer grinding usually takes place in rotating vessels, such as ball and rod mills. Very fine grinding, to sizes less than 10 µm, requires high energy and attrition mills are often used. These have much lower throughputs than the primary crushers and an example of an attrition mill is illustrated in Figure
Milling. The tempered grain is ground in a series of rollermills to remove the bran and to cut the endosperm. Between each rollermill cycle, the ground grain is sifted and separated into various sizes. Middlesize material is sent to a purifier, or shaking sifter, .
The basic function of the lead screw is to move the turret by a precised increment for every rotation of thescrew. As a result of this it allows the machine to generate threads in a work piece and helps in generating precise length and diameter dimensions, and also to maintain a .
