The existing ball press mainly comprises a machine body, two rotating rollers and two roller sleeves, wherein the two roller sleeves are sleeved on the rotating rollers, the two rotating rollers are rotatably connected in the machine body through rotating shafts and rotate in opposite directions through gears, and the rotating rollers are driven to rotate through a power device. And the roller sleeve is provided with a plurality of rows of ball sockets, and the ball sockets on the two roller sleeves are matched with each other to form a spherical cavity for extruding materials in the ball sockets into balls.

By adopting the ball press machine, when materials fall into the ball socket and rotate along with the rotating roller, the materials are easy to fall out of the ball socket to form leakage, so that the amount of the materials in the ball socket is reduced, and the phenomenon that the materials cannot be compacted (namely in a loose state) or even cannot be extruded into balls can be caused in the subsequent ball extruding process due to the fact that the materials in the ball socket are less, and the ball forming rate is low. Even if the materials are extruded into balls, the formed cold balls are in a loose state, and if the cold balls directly fall onto a conveyor belt, the cold balls are easy to loose, so that the ball forming rate is further reduced.
