The writer investigated the influence of the lug angles and the weight per unit length of the rotor, upon the load characteristics of puddling rotors. The results can be summarized as follows:
(1) To diminish the load of the puddling rotor, the cutting angles of the lug should be decreased, the rotations lowered, and the machine weight per unit working length lighter. From the writer's experiment, it can reasonably be said that the lug angles range from 45° to 60°, the weight from 0.7kg to 1.0kg per centimeter, and the rotations of the rotor from 46 to 72per minute.
(2) Greater weight per unit working length and smaller angles of the lug made rotors sink deeper, which in turn increased the working area in cross section. As the result, the puddling resistance increased. In determining appropriate angles of the lug, it should be noted that smaller puddling resistannce and higher breaking and-stirring effect be taken into consideration, as well as the load characteristics.
