[0002] In the plastics, rubber, chemical and other industries, the preparation and processing of masterbatch is a key process; after the production raw materials are produced by the masterbatch granulator, the masterbatch still has a relatively high temperature and needs to be cooled before packaging.

The spiral vertical vibration loader lifts the masterbatch to a high place by the vibration of the motor, and cools the masterbatch by blowing air through the blower during the lifting process. However, the cooling efficiency is low only by blowing air, and a long stroke is required to lower the temperature of the masterbatch, resulting in a high height of the spiral vertical vibration loader, which increases the production cost and limits its use.
