skinpass mill of 2Hi or 4Hi equipped with a bender and the tension leveler of type (A) of Fig. 3 are common. The HSPL of the latter hitherto has been constituted of a pay-off reel, a 4Hi equipped with a bender, and a tension reel; however, a hi-tension hot mill line having a bridle roll and a tension leveler added to that also exists.
Cascade control uses the reduction concept (R-Factor) to calculate the mill cascade speed reference. This parameter, directly related to rolling fundamentals, simplifies the setup and operator control. During production the loop and tension control automatically adjust the R- Factor, ensuring minimum material stress between the stands.
mill stands is formally removed by state transformations. Jiao et al. (2011) developed a decentralized adaptive con-troller for strip thickness, strip tension, and looper dynam-ics based on a nonlinear model. The main loads of the looper are its own weight, the weight of the strip, and the forces due to the tension .
System Tension (Machine) Output / tension is influenced only by operator adjustment. If the operator walks away, the control output does not change Therefore, on unwind/rewind, tension will change as the roll diameter changes Manual Systems. Example: Driving a car and as you go up a hill, you

Dynamic Tensioning System (DTS) The Wolftek Dynamic Tensioning System (DTS) can be installed on any make of planer mill line and will dramatically increase production and efficiencies. The incredibly fast and accurate system knows exactly where the roll is and how much pressure is applied.
4 Due to the interaction of raw materials and kiln gases, rotary kiln systems have inherent SO2 removal efficiencies ranging between 40-99% of the sulfur input to the system. The literature suggests that 50-70% of the remaining SO2 will be removed from exhaust gases when passed through an in-line raw mill system.
looper and tension control system tension looper roll M Fig. 1. Tension and looper control in finishing mills Where, ASR: Automatic Speed Regulator, ACR: Automatic Current Regulator from mass flow unbalance. For example, in the case of low tension, the looper angle increases to get proper tension, resulting in the stable
cement industry the ball mill was really an epoch-making breakthrough as for almost 80 years it was the predominant mill for grinding of raw materials and coal, and still today is the most used mill for cement grinding. Over the last three decades the vertical roller mill has become the preferred mill for grinding of raw .

The tension force could be delivered by a spring, air, liquid, or even weights. Any of these should be insensitive to environmental changes. There would be a problem if your mill manufacture uses a tension system that the energy to produce the force is switched on for only part of the time the tension is needed. Shame on them.

A tube mill is a revolving cylinder of up to five diameters in length used for fine pulverization of ore, rock, and other such materials; the material, mixed with water, is fed into the chamber from one end, and passes out the other end as a slurry. Both types of mill include liners that protect the cylindrical structure of the mill from wear.
