Use and repair of formwork

During the use of the template, when cavitation and groove wear on the surface of the pelletizing belt is found, the template must be unloaded in time and sent to a professional manufacturer for repair.

According to the surface wear situation of the template granulation belt, it can be completely restored by repairing the granulation belt or replacing it with a new one.

During the service life of the template, under normal circumstances, the template can be repaired three times, and the grinding amount of each template is 0.2-0.5mm. After the wear is repaired more than three times, the pelletizing belt needs to be replaced. In special cases, part of the outlet holes needs to be blocked.
