The crystallizer is a key equipment in the sugar production process, and it plays an important role in the quality of sugar. The crystallizer stirring is a key component in the development of the sugar-making and boiling process from natural circulation to forced circulation. During the sugar-making and boiling process, the syrup in the crystallizer accelerates the circulation under the stirring action, and the water in the syrup evaporates quickly, shortening the boiling time and improving production efficiency. The wear of the bearing sleeve under the crystallizer stirring is the main reason for the vibration of the crystallizer stirring during use. At the same time, the metal chips caused by wear also affect the quality of sugar.
