Description

Technical Field

[0001] The utility model relates to a granulator, in particular to a hydraulic power roller-pressing granulator. Background Art

[0002] Dry roller granulator is widely used in the preparation of granular products from powdered materials. It is widely used in many industries and has the characteristics of being applicable to a wide range of materials. For example, it can be used for the granulation processing of various chemical raw material powders, metal smelting additives, various food additive powders, water treatment agents, petroleum treatment agents, snow melting agents, feed additives, battery materials and mineral materials.

[0003] The working principle of the roller granulator is to use a pair of rollers to extrude the material. Due to the high extrusion pressure, the torque required for the roller to rotate is large. At present, the rollers of the roller granulator are mainly driven by a high-power motor with a dual-output shaft reducer. The high-power motor and the dual-output shaft reducer are costly, bulky, and have high working energy consumption, resulting in the existing roller granulator having the disadvantages of high production cost, high working energy consumption, and large space occupation. In addition, during the start-up and shutdown process of the roller granulator, due to inertia, the motor is prone to overload, which affects the service life of the motor and the dual-output shaft reducer.

In addition, the hydraulic motor with the same transmission torque is smaller in size, making the roller-type granulator more compact and occupying a smaller space. In addition, the hydraulic motor drive has a flexible characteristic, which can play an overload protection role, which is conducive to improving the working stability and service life of the roller-type granulator.
