Accumulating strip before the mill for exampleif the tube mill runs at 100 feet per minute (fpm) (30 meters per minute mpm) and it requires four minutes to complete the end joining operation400 feet (122 meters) of strip will be used by the mill while end joining occursthe accumulator must therefore have a capacity of at least 400 feet (122 meters)a tower can also be used.
Our products sell well all over the world, and have advanced technology in the field of crushing sand grinding powder.
