2. Roll Deformation of 4-High CVC Mill. ... It can be obtained from the above analysis that the axial force of work roll consists of two parts which generates from rolling force and interroll force, respectively. ... is the nominal radius of work roll , which varies with work roll grinding.
The rolling force, measured at each end of the mill stand, varies between 4500 and 7000 kN, making the total rolling force variation from 9000 to 14 000 kN. The thickness of the steel strip was with traditional ground backup rolls 2.2 mm and with 3D ground rolls 2.0 mm. The results are synchronous time averages Fig. 9.
Flatness measuring the flatness measuring roll On the exit side of the mill the strip is bent over a segmented roll, the flatness measuring roll. This roll measures the force on each segment and in this way the flatness of the strip can be decided. Figure 2 shows a principal sketch of a flatness measuring roll. Figure 2.

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
Principle of grinding The working principle of the High Pressure Roller Mill is two rolls, which are counter rotating at the same circumferential speed. One roll is connected to a hydraulic system which creates a radial force. The feed to the rolls creates a so called bed of material in the roll gap. Within this material bed, the product is ...

In recent days, the Ball mill grinding systems are used with the Roller press and it is developing very fastly. The primary grinding
Forged Rolling Mill Rolls. Over the years, NKMZ has supplied over 1.3 million tonnes of rolls to more than 43 countries and is currently producing 20,000-25,000 tonnes of forged rolling mill rolls per annum. NKMZ rolling mill rolls are made with alloy forged steel with Chromium content of 2%, 3% and 5%. They are used in different types of ...
2 Roll thin oil system. The main motor drives the millstone to rotate through the reduction box, meanwhile, the air flow gets into the mill through air intake. The materials come out of the screw feeder and fall on the center of the millstone, and then they will move from the center to the edge of the millstone under the affect of centrifugal force.
Hydraulic operation achieves maximum roll force for the hardest grinding products. Four-point adjustment and easy to read pressure gauges provide repeatability to improve quality and increase productivity. This mill enhancement provides push-button control of the roll force.
