The rod mill is named after the grinding body loaded in the cylinder body is a steel rod, and is widely used for first-grade grinding of artificial stone sand and ore dressing plants. The rod mill is driven by a motor to rotate through a speed reducer and peripheral large gears in a speed reducing way or by a low-speed synchronous motor to directly rotate through the peripheral large gears in a speed reducing way. The cylinder is filled with a proper ore grinding medium, namely a steel bar. When the rod mill is used, the steel rod is lifted to a certain height under the action of the rotating centrifugal force of the cylinder body and the friction force between the steel rod and the cylinder wall, and falls down in a throwing or dropping state. Ground slurry continuously enters the cylinder body from the ore feeding port, is crushed by the moving steel bar, and is discharged out of the machine through overflow and continuous ore feeding force so as to carry out the next working procedure.
However, the conventional rod mill cylinder has a ratio of length to diameter of 1.5 to 2.0, and is horizontally supported by providing bases at both ends thereof, but due to the gravity of the cylinder itself, middle bending deformation may occur with long-term use, thereby reducing the service life of the rod mill. Meanwhile, the steel bar can not be lifted under the action of the rotating centrifugal force of the cylinder body and the friction force between the cylinder body and the cylinder wall if the rotating speed of the cylinder body is low or the friction force of the cylinder wall is insufficient.

Furthermore, the diameter of the steel bar is provided with a plurality of specifications. So set up, through the rod iron of multiple specification, ensure that the grit can thoroughly be smashed, the particle diameter after smashing is littleer.
Furthermore, the feeding device is funnel-shaped, and the inner side of the feeding device is elastically hinged with a dust-proof plate. So set up, when the feeding, the dust guard is rotatory by the gravity of material, can not influence the feeding of material. After the feeding is finished, the dust guard elastically resets, and hot steam and dust in the barrel are prevented from being discharged from the feeding device.
Furthermore, an air suction device is arranged outside the discharge end of the discharge device, and an air outlet end of the air suction device is connected with an air filtering device. So set up, utilize getter device in time to clear up the discharged dust in the barrel, discharge after filtration again, avoid the polluted environment.
Compared with the prior art, the beneficial effects of the utility model are that:
the middle part of the cylinder body is provided with the supporting mechanism, so that the middle part of the cylinder body can be supported, and the cylinder body is ensured not to be bent and deformed. Because be equipped with the dwang of rotating the connection between supporting seat and the barrel, utilize the roll effect of dwang, avoid the rotation of barrel to be obstructed.
Utilize the inside lining of raised grain design, usable its protruding position promotes the rod iron when the barrel rotates, ensures that the rod iron can effectively be promoted, guarantees the ore crushing effect.
