Rod Mill - an overview | ScienceDirect Topics
Jean-Paul Duroudier, in Size Reduction of Divided Solids, 2016. 3.7.4 Performance. Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture.

Study of Short Stroke Control Model on Hot Rolling Mill
strip is going to enter the rolling mill. The least square method is used to fit the control curve, with the data of the points. After the curve fitting, the polynomial equation is sent to the PLC for the strip head and tail sharp control. The flow chart of the control model is shown as Figure II.
Strip Thickness Control of Cold Rolling Mill with Roll ...
In rolling mill, the accuracy and quality of the strip exit hickness aret very important factors. To realize high accuracy in the strip exit thickness, the Automatic Gauge Control (AGC) system is used. Because of roll eccen-tricity in backup rolls, the exit thickness deviates periodically. In this paper, we design PI controller in outer loop
Steel Plate Mill Process Control | NDC Technologies
Plate mills roll the heavy plate to the proper thickness and then square the ends and divide the plate into the desired length. LaserSpeed® Pro non-contact gauges are used at three locations on a plate mill. First, a gauge is mounted upstream of the shear to measure the overall length of the plate.

1.2 Key building blocks of PLC and SCADA systems 1.2.1 PLC Systems. In the past, processes were controlled manually, which was a very tedious job. During the early years of control, hard-wired relays were used to control the same process. However, relays could not meet all the needs of modern times, and a faster solution was required.
US6077002A - Step milling process - Google Patents
A blank is milled using a rotating mill. A groove having a bottom is first cut across the blank to partially expose a sidewall in the blank. The sidewall is then cut by the mill. By alternately repeating cutting of the groove and sidewall, the groove is milled deeper in the blank to form a pocket along which the sidewall extends. Since the sidewall is formed in steps, improved efficiency and ...
