What is Spiral Classifier in Mineral Processing?
The spiral classifier can be divided into three types: high dam type, low dam type and submerged type. 1). High Dam Spiral Classifier. The high dam type spiral classifier means that the overflow dam is higher than the spiral axis of the spiral, but lower than the upper edge of the spiral at the overflow end.
