ROLLER MILL Principle: The material is crushed (compressed) by the application of stress. The stress is applied by rotator wheels, rollers. 9Fig: Roller mill. Feed Hopper Rollers 10. Working: The rollers are allowed to rotate. The material is feed into hopper through gap between two rollers by applying high pressure material is cursed.

Forplane stress,the stresses z, xz, and yz are assumed to be zero. The stress-strain relationship is: 2 10 10 1 000.51 xx yy xy xy E 2 10 [] 1 0 1 000.51 E D is called the stress-strain matrix (or the constitutive matrix), E is the modulus of elasticity, and is Poisson's ratio. xx yy xy xy D

The roughing mill consists of six flat-vertical short stress mills arranged alternately. The nominal diameter of the roll is 550 mm, and the length of the roll body is 760 mm. The range of application is 610 mm to 520 mm. There is a crank flying shear at the exit of rough rolling mill. The maximum cross-section is 4000mm.

The following is the working principle drawing of symmetrical 3 roll bending machine. Driven roller Ⅱ, Ⅲ is driven by motor and reducer, which rotates in the same direction at the same speed (or in the opposite direction). Because of the friction between the roller and the plate, the plate is driven forward and the roller is rotated.
