Many patterns power screw press, screw press but all have a similar structure and principle, only difference being that the main components of the type. The main components of the screw shaft screw press, squeeze cage, feeding device, adjusting for cake and transmission shifting devices. Our screw press model is based on the inner diameter bore virgin named. By pressing the classification process, ZX10 type, ZX18 type, ZX28 type belong pressure press, ZY24 type, ZY28 type belongs to the pre-press. Classification according to production capacity, ZX10 type, ZX18 type, ZY24 type is a small press, ZX28 type, ZY28 type in recent years developed a large press, their production capacity respectively, press 35 to 40 tons / day and pre- pressing 140 to 160 tons / day. According to press structural type classification, ZX18 type and type the same class models ZY24 old oil press prices, ZX28 type and ZY28 type press belongs to the same class models, ZX10 model is a model alone. Here are the main working member screw press and thus understand the difference between the structure and the structure of different types of virgin oil press machine on. If the virgin material virgin material internal friction and particle-particle friction and squeezed between the outer surface of the shaft between the particles and the friction material than virgin pressed cage between the surface, then the virgin material generated with the shaft rotation. When screw press work, pressing material rotates with the shaft movement is not normally allowed. In the old press pressing cage surface resistance and pressed virgin material particle surface is large cage to offset the rotation with the shaft to force weeks, but in the intermediate layer Nanyang Which is good old-fashioned press, virgin material particles depends mainly on internal frictional force, the resistance is small, especially in the feed section, the friction between loose particles virgin material is smaller, then it is easy to produce the phenomenon of virgin materials with the shaft rotation. In addition, the friction of virgin and extra virgin material between the shaft surface is also prone to rotating with the shaft. Thus press, along with the axis of rotation of each radial layer of virgin material situation is inconsistent. In order to prevent the phenomenon of virgin material with the shaft in the screw press means pressing a blade bore and shaft surface finish, and when squeezed juice bar cage surface means it has a "spine sex."
