On high-speed machines, dryer bars are normally used to break up the rimming laminar condensate layer and thus improve heat transfer. For a given diameter dryer, the speeds at which the above stages occur depend on the amount of condensate in the dryer. As the quantity of condensate in a dryer decreases, rimming will take place at a slower speed.
The yield and economy during hot strip rolling depend on developing high capacity components fulfilling further the increasing customers' demands for cost and resource effective production figures. The paper gives an overview of the latest developments for high capacity components and tools of the SMS group for conventional hot strip mills and CSP® plants. The SMS components …

Non-uniform nip pressure: See above. Crushed roll. Sometimes called a "baggy sock roll" and is the result of stacking rolls on end in an excessively high pile which in turn causes the lower rolls to fail in an axial direction. Excessive axial pressure: Stack rolls to a more conservative height. Winding too soft: Wind rolls harder. Dished roll

The grinding motion is a rotating one and is also extremely gentle even on brittle materials." The mill throughput can be adjusted via the rotational speed and includes particles of between 0.5 and 10 millimetres. The customer is just as flexible in the integration of the AFC mill into his system concept.
Due to the high rigidity possible, improved accuracy with movements of 0.1 microns is possible. Due to the oil film, the stick-slip phenomenon that is ever-present in roller contact guideways is also eliminated due to there being no physical contact …

Roller mill. With a roller mill, a product is compressed and reduced between two counter-rotating rotating rollers. A major advantage of this process is that the proportion of fine particles (powders or dust) remains minimal compared to other grinding principles and …
Conditions such as high temperature, contamination, exterior vibration, etc. will lead to an a3 factor less than 1. If the lubrication is superior and the operating speed high enough, a significantly improved lube film can develop between the bearing's internal contact surfaces justifying an a3 factor greater than 1.0.
Vertical Roller Mill The vertical roller mill (VRM) shown in Figure 4 is an air swept, medium-speed, vertical pulverizer with integral classifier. It pulverizes coal by applying hydraulically-loaded grinding pressure through three grin- ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal
