Ore Grinding cycle
1. Classifier in grinding cycle In the grinding cycle, a classifier, a hydrocyclone or a screen are needed to connect with a mill to form a unit. The function of the grading equipment is similar to the effect of the sieves in the crushing process, such as pre grading and grading, and overflow control classification. 1.1. Spiral classifier The most commonly used classifier is a spiral classifier, which is divided into three kinds: high weir, low weir and sunk type. According to the number of spiral , it can be divided into single spiral and double spiral classifier. Spiral classifier with a sloping semi cylindrical trough 2, tank equipped with one or two spiral 3, it is the role of the sand pulp stirring and transported to the upper end of the chute. The spiral blade is connected with the hollow shaft, and the hollow shaft is supported in the bearings at both ends of the upper and lower sides. The transmission device is installed in the upper trough, the spiral bevel gear ...
