mechanical engineering: Types of rolling mills
3: Four high rolling mill: It has a roll stand with four parallel rolls one above the other. The top and the bottom rolls rotate in opposite direction as do the two middle rolls. The two middle are smaller in size than the top and bottom rolls which are called backup rolls for providing the necessary rigidity to the smaller rolls. A four high ...

11.25 Clay Processing
crushers, smooth roll crushers, toothed roll crushers, and hammer mills are used for secondary crushing, which further reduces particle size to 3 mm (0.1 in.) or less. For some applications, tertiary size reduction is necessary and is accomplished by means of ball, rod, or pebble mills, which are often combined with air separators.

Rolling Mills: 6 Different Types of Rolling Mills [Images ...
In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in equipment, rolling is done in the ...

Planetary Rolling Mills: The Planetary Mill is a medium output mill for rolling of steel strip. Its output is less than continuous mills of many stands but more than the reversing two-high or the three-high mill. This mill can be used to roll all metals but it is especially useful for those which have low ductility.
