Let me help you with a quick back of the envelope calculation. If you are using a 270 Liter Tangential Internal Mixer, you are engaging at least two units of 26″x84″ two-roll mills in the downstream section. Each 26″x84″ two-roll mill, requires around 180 kW (minimum) motor power – totaling to 360 kW (=180 x 2) only for the mills.

This refers to mixing operations using horizontal two roll mills. The operator (usually known as a mill man) places the various ingredients in the nip formed between the rolls and mixes the compound by cutting it off the rolls and re-feeding it into the nip until all the ingredients are added. Mills are used not only for blending of

A dandy roll made for the purpose of imparting a laid finish to paper. It is composed of wires running parallel to the roll's axis and attached to the frame by evenly spaced chain wires that encircle the circumference of the roll. The laid wires are affixed on top of the transverse chain wires, rather than being wove over and under them.

Tram Your Mill Carefully, or Put it Out of Tram Intentionally. We're talking about facemilling and fly cutting here, or area finishing. When it comes to area finishing, there are two schools of thought on tram and surface finish–either get your mill trammed near perfectly or put it out of tram just a little bit.

rolls on two support rollers, and the shell moves circumferentially relative to the tire ID. Any relative misalignment of these interactive components results in mechanical instability. Consider the rolling motion of the tire on a support roller. If the tire axis is parallel to …
conditions following cold rolling using polished rolls, a highly reflective finish, that will reflect clear images, is obtained. This ultra-smooth surface is less likely to harbour airborne contaminants or moisture than any other mill finish, and it is easy to clean. To maximise resistance to corrosion in the as-supplied condition, mill finish ...
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 [0.0025 mm thick]. The work roll in these mills can be as small as 6 mm diameter – made of tungsten carbide.

Laminating two or more layers of different polymers together can produce a product that has barrier properties far superior to those obtained when only one polymer is used. Frequently, one of the polymers used is a gas or moisture barrier layer based on polyvinyl alcohol (PVAL). To produce three layered structures, two or three extruders are ...
A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product. The metal changes its shape gradually during the period in which it is in contact with the two rollers.
The fabric is a primary raw material for making garments and the costliest item among the items required for garment manufacturing (in most of the apparel product categories). As the standard operating procedure, in textile mills fabrics are checked prior packing fabric and in a garment manufacturing unit fabric is inspected prior to bulk cutting.
A typical layout of a mill using the kraft chemical pulping process is shown in figure 2-1. Mechanical, semichemical, and sulfite pulp mills differ in detail, particularly in wood preparation, fiber separation, and bleaching, but many of the downstream refining, bleaching, and papermaking processes are similar.

Stainless steel with a 2B mill finish is a bright, relatively defect-free finish produced by a final cold roll pass using polished rollers. It does not show any grain and has been compared to a "cloudy mirror" in terms of appearance. ... Two other finishes; #7 and #8 are buffed. The surface of #8 is very nearly flawless. The Ra on a #8 ...
Formula (5) is used in making tabulations for mill use. As used in these formulas the specific gravity of the ore is obtained simply by weighing a liter of mill pulp, then drying and weighing the ore. With these two weights formula (2) may be used to obtain K, and then formula (1) to convert to S, the specific gravity.

Two High Reversing Mill: In this type of mill, the rollers are both adjustable. In these mills, rotation of that two rolls is made in two different directions. In this operation, the metal is passed between two rollers that rotate at the same speed but it is in the opposite direction.
4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.
