Product Description

Ball press machine is a key suppressing machine in the pellet technology complete equipment developed and designed on the principle of extrusion molding for powder material. Our company received the national patent of invention certificate of large ball press machine with patent No. ZL2007.1.0163951.4. Recently, the first GY2412 ball press machine has been successfully manufactured in our factory with diameter of press roll 2.4 meter and width 1.2 meter. The capacity of the machine can reach 50-100t/h according to different material. Our product is the largest high-pressure ball press machine of highest pressure and largest capacity featuring in advanced product design theory, rational structure, affordable forcing feeding, adjustable pressure, feeding intellectualization, ball production automation with inlaid rolling skin easy to exchange and maintain.

Working principles

At work, the material is fed uniformly into the inlet of large ball press machine in ration by the feeder through the middle silo and then goes into the prepressing feeding unit above the main engine. Keep the level of material inside the prepressing feeding unit stable and use the prepressing spiral to force the material to the middle part of the two rollers. After the precompression and degas, the material is forced into the arc notch between two rollers on which surface is studded with ball socket of the same shape. On the mesh transmission of synchronous gear reducer, two press roll rotate at same speed in the opposite direction, putting the material in the arc notch into the groove and forcing it to be compressed. With the continuous rotation of press roll, material of compressed shape will fall down from the ball socket due to its elastic force and gravity when surpassing the central line. Since then, the process of ball compressing has been completed.
