螺旋分级机按其螺旋轴的数目可分为单螺旋和双螺旋分级机；按其溢流堰的高度以可分为高堰式、沉没式、低堰式。
我厂可根据客户的要求生产标准型、加长型螺旋分级机。螺旋分级机有左、右式之分，订货时须注明。
Spiral classifier is simple, reliable, easy to use, etc. ,which is the most widely used classification equipment .in the concentrator .It is mainly used for pre-classification and grading inspection in the wet grinding circuit. It can also be used to wash off the mud, and dehydration in ore-dressing practice.
Spiral classifier according to the number of screw shaft can be divided into single-and duplex-spiral classifier; according to a high degree of the overflow weir can be divided into high-weir, sank-and low-weir.
Our company is able to according to the requirements of customers and produce standard, extended-spiral classifier.
