realized by implementing two different windings systems in the stator, one for lower speed and one for higher speeds. For example, if the first winding system has a pole pair number of 2 and the second winding system a pole pair number of 8, a speed spread factor of 4 is achieved. For a grid connected machine ( . . 50 Hz),











This is achieved in the plasticating unit where the material is melted and mixed by an internal batch mixer or a roll-mill. The paste-like mass is then fed between the nips of the first two rolls; the first pair of rolls controls the feeding rate, while subsequent rolls in the calender calibrate the sheet thickness.





Two Roll Mill widely used in rubbers and plastics industry for polymer mixing, such as PVC, color master batch. It consists of roll, bearing, gap adjusting device, heating system, electric control system, safety device, etc.The adhesive package is on a roller with a speed ratio of 1:1.4 (or a speed ratio in accordance with the standard).



Milling machine is another most important machine tool after the Lathe machine tool and drilling machine.. In this machine, a multipoint cutter is rotating against the workpiece and material removed from the workpiece accordingly.. In today's article, you will learn about the definition, parts, types, and operation of a milling machine, also at the end of the article, I will add the ...



•Roll-strip contact length L •Average strip width w –despite the fact that spreading, or an increase in width, may actually occur if edger mills are not used •Average true stress of the strip in the roll gap Y avg •Assumes no friction and thus predicts lower roll force than the actual value •Power per roll (SI units)= pFLN / 60,000 kW



If the cold mill rolls or hot mill coils have too little crown, the mills will roll out the edges and create edge wave (see Figure 9). This is fairly common in mill master coils. Mill work rolls and backup rolls bend and compress under the vertical loads it takes to reduce plate or sheet coil thickness. In theory, if the work roll surfaces were ...

One does not chase two rats and avoid coming up with nothing. (Never try to go in two directions at once.) Also Ẹní bá léku méjì á pòfo. A kì í lọ́mọ lẹ́hin kọ oúnjẹ. One does not have children at one's rear and yet refuse food. (No amount of anger or distress should keep one from looking after one's dependents.)





The action-entertainer has two heroines- Sameera Reddy and Bhavana. Asal's success was predicted by Superstar Rajinikanth at the launch of the movie itself. The top actor, who was the chief guest of the function said, "When I was down after 'Baba' debacle, Ramkumar and Prabhu, sons of Sivaji Ganesan, did 'Chandramukhi' with me.



Rod mills: Horizontal rods are used instead of balls to grind. Granularity of the discharge material is 40-10 mm. The mill speed varies from 12 to 30 rpm. Planetary mill: High energy mill widely used for producing metal, alloy, and composite powders. Fluid energy grinding or Jet milling: The basic principle of fluid energy mill is to induce







For this system, the tube feeds between an upper and lower roll, while on either side two adjustable guides move to produce the desired bend angle. Many use roll bending to produce spirals. If a workpiece has a one-diameter pitch and a large radius, the operator can lift the tube after one revolution to produce a continuous coil.

finishing mills, which will roll the steel in tandem with one another. The workhorse roughing mill has 135" wide rolls for rolling 'broadside' (as the first roughing mill is commonly called) to make a slab wider. A 5,000 hp motor drives 42"-diameter work-rolls through 28:1 gears to reduce the slab's thickness by as much as 2-½".

Shah & Rajesh J. Shah (as administrator of the Estate of Juthalal Virpar Shah) v Vijay Amritlal Shethia.



motors. These are known as mill stands. The layout of a rolling mill varies, from a simple single stand mill to several stands positioned either side by side or in a line. A mechanism, commonly called a roller table, directs the work piece to the rolls, and another roller table for handling the pieces emerging out of the roll.
