Spiral ClassifierFeatures:

1.Available in three standard spiral pitch sizes

2.A variety of spiral lengths and speeds can be selected depending on the application

3.Three standard tank sizes

4.Three pool depth series

5.Motorized hydraulic, manual hydraulic, and screw lifting device options

6.Reliable drive arrangement

7.Large diameter tubular shaft is supported by upper and lower bearings

8.Cast steel flight arms are short with a large cross-section that will resist big loads without bending

9.Pre-formed steel flight sections bolt to the flight arms

Structure and composition:

This kind of Spiral separator is composed of a U trough, spiral, transmission, elevator machine, support bearing, etc. The down flow weir of the high weir type is higher than the lower bearing, but lower than the upper edge of the lower spiral. There is a horizontal long axis with helical blades in the U trough, and a down flow weir designed in the lower place. The transmission is installed in the upper chute; the upper main spiral shaft supports the bearing on the drive frame, while the lower bearing is fixed at the level of the elevator. The elevator is able to make the lower part of the spiral ascend and descend to regulate the distance between the spiral and the bottom of the chute as well as the confirming size of the spiral. Meanwhile, the spiral should be raised up at the time of a stop in order to avoid the desilting burying the spiral that will impinge on starting. The bearings of the main spiral shaft are quite vital parts, due to relatively harsh working conditions; the requirements for the sealing of the bearings are high. At the same time, the operator must strengthen the maintenance.
