Structure

1. gearing 2 spiral 3 cell 4 lifing mechanism

Single spiral classifier is formed by gearing, spiral, cell body and lifting device etc.

1. Gearing: The transmission of spiral is achieved by motor through V-belt.

2. Spiral: It is the main components of this machine, it formed by the main shaft, frame, spiral blades, lining iron frame. The frame, spiral blades, linked iron are formed to connected spiral surface, because the shaft is constantly rotating, so the role of helical face is mixing the slurry , make fine particles flow from the overflow weir, coarse mineral particles conveyor from the screw first to discharge port.

3. Cell: Welded by steel plate and shaped steel, it is the body of screw classier.

4. Lifting mechanism: The movement of machine screw parts is achieved through the cycloid reducer, gear, screw. When classifier stop working, the materials in the water chute will precipitated, in order to avoid damage by precipitation and the transmission will occurs over load when it move again, so must lift the screw spindle from water chute and make it leave the precipitation level, for this design lifting mechanism.

Characteristic

The single spiral classifier is an up-dated one and it has the following characteristics:

(1)Up-dated classifier increases a automatic sand-return device at the sand-return part, lift ore sand that discharged at tank bottom to a proper position at tank wall, to adapt the configuration of ball mill cancelled big spoon head.

(2)When ball mill has cancelled big spoon head, it can usually save electricity 1-1.5 degrees per ton ore, meanwhile, avoid frequent maintenance about big spoon head, and slow down the wear speed of small gear, improve ball mill run speed, save electricity obviously.

(3) When ball mill has cancelled big spoon head, it has no effect on specification and grinding ability of classifier.
