A special roll stand is used to direct the strip from each coil to the mill. This roll stand indexes to the next lower coil each time a coil is depleted. In most operations, enough coil can be preassembled to satisfy the requirement for one shift, so mill operation is continuous for at least one shift.
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed

Introduction. Since the load on the plate roll bending machine is large, so the requirement for the parts strength is high. In addition, due to the fierce competition in the market, it is urgent to reduce the cost of the plate rolls, so it is imperative to design the machine accurately and reliably.
Years ago tube and pipe producers relied mainly on eddy current testing and ultrasonic testing for detecting short- and long-duration weld faults, respectively. These testing systems are still useful and in many cases required, but the spread of electronic technology has provided many more types of testing equipment for use on tube and pipe mills.

LD, HD, 1212, 1618 & 1824 Models depict a typical horizontal roll-bending machine. Its major parts include the bottom, urethane-covered roll, the top (steel) roll, and the overarm, which can be opened and closed to facilitate the removal of a finished piece part. (See page 17 for models). Model V-1006 depicts a typical vertical roll-bending
The solution: life the upper roller 5 mm, place one 3mm sheet steel mat under the offset position which contact with the bottom roller, jog control the bottom roller to move the pad into the place between the plate and bottom roller. Press upper roller for 3-5mm, to make the left and right migration move toward the alignment direction.
