Pelletizing knife holder
Product description
The pelletizing knife holder is also one of the key components of the underwater pelletizer equipment. Its working characteristics directly affect the quality of the granulated product and the service life of the Granulation die plate and the Pelletizing knife.
The pelletizing knife holder is divided into a fixed pelletizing knife holder (rigid cutter head) and a follow-up type pelletizing knife holder (flexible cutter head) two kinds.
Due to the thermal stress of the template and the deformation caused by the subsidence of the guide rail base of the underwater granulator, it is easy to create a gap between the cutting edge belt and the template granulation belt installed on the fixed cutter head. In the granulation process, it is easy to appear the phenomenon of pad knife, knife wrapping, and even wax filling. The fixed pelletizing knife holder has high requirements for the installation and adjustment of the cutter and the template. In recent years, the new equipment has been gradually converted into a follow-up type pelletizing knife holder.
The follow-up type pelletizing cutter head developed and designed by Shenyang Jinfeng is to ensure that the cutter head is under a certain external force by using special connection material and connection method under the condition that the cutter head drive shaft has sufficient transmission torque and axial force Under the action, with the deviation of the template granulation belt, a certain range of end-face swing compensation is realized. Its biggest feature is to compensate in any direction of 360 ° around the cutter head circle, and its maximum compensation is 1mm. Therefore, it not only meets the requirements of end face swing, enables the cutter and template to achieve a uniform fit, improves the quality of pellets, but also extends the service life of the cutter and template.
