sand spiral classifiers

Sand Classifying Tanks

Sand Classifying Tanks have been a staple in the construction aggregates industry for more than 50 years. Also known as water scalping tanks, Classifying Tanks efficiently handle large amounts of water and offer the ability to create multiple specification products from one feed. Classifying Tanks are divided into sections known as stations.

Figure 13.1 is a sketch of a spiral classifier where the spiral conveyor is installed within the bowl. The spiral operates along the sloping sides of the tank and dredges the thick sludge out of the tank. Figure 13.2 shows the spiral conveyor replaced by a rake, which drags the sand up the incline for discharge. Download : Download full-size …

What is Spiral Classifier in Mineral Processing? | Mining Pedia

Odor-control is achieved by scrubbing the grit of organics and ...

Troubleshooting of 5 common faults of spiral classifier

Bent spiral blades or spokes. Solution: By repairing or replacing new spiral leaves and spokes. 4. Gears are easily damaged. Solution: The damaged gear should be replaced in time and maintained regularly, and the sand washer shaft should reach the specified level. 5. Vibration of lifting rod.

Classification of Materials and Types of Classifiers – …

In these classifiers the required pool area is balanced with the sand raking capacity of the spiral by the design of the tank. Heavy particles have time to settle at the bottom and the spiral conveyor moves the settled particles upwards along the floor of the trough. Spiral classifiers are used for close circuit grinding.

rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated. The settled material is thus slowly moved up …
