Fig 4 Roll configurations in rolling mills. Twohigh mill roll configuration This is the most commonly used rolling mill configuration. In this configuration, there are two horizontally mounted rolls. The rolling mill motor drives either both rolls (top and bottom) or only one roll (normally the bottom roll) with the top roll rotating due to the friction between the roll and the work piece.

Cluster mill or Sendzimir mill stand In this rolling mill stand, each of the work rolls is supported by two backing rolls. Cluster mill and Sendzimir mill are used for rolling thin strips of high strength materials and foils [ mm thick]. The work roll in these mills can be as small as 6 mm diameter made of tungsten carbide.

The distance between the mill rolls can be varied and this gap is known as nip. The speed difference between the rolls is called friction ratio and it allows the shearing action. The back roll moves faster than the front roll; a common friction ratio is 1: Two roll mill mixing is also known as open mill mixing. Internal mixer

2. Rolling Cluster Mill: ( Types of Rolling Mills ) A rolling mill with four levels is known as a cluster rolling mill. Each of the two working rolls within this rolling mill is backed by two or bigger backup rollers that can roll rigid materials. Rolls with a minor diameter but a very long length may be required to get the effect sought.

In order to incorporate particles and DCP into the EPDM rubber compound, a Bunbury internal mixer and tworoll mill were employed. The processing temperature used in Bunbury internal mixer was 130. °C with the rotor velocity of about 20 rpm..

The basic function of the three roll mill is a differential speed between the three rolls. The difference between the second and the third rolls is two to four times higher than the difference between the first and the second rolls. The dispersion takes place in the second nip; the first nip regulates the feeding of the second "dispersing" nip.

A hammer mill contains a drum in which many little hammers are attached to the inside. As the material goes through the mill, the hammers collide with the material. The force of this collision breaks the material down until it reaches the desired size and passes through a screen. A roller mill uses a more controlled mechanism.
