Introduction to Spiral Classifier
Our spiral classifier are made to give you the best pool area and overflow velocity requirements. By combining the appropriate submergence from the spiral and among the tank designs either 63 combinations is achievable in Straight, Modified or Full flare tank designs. The correct mixture of pool depth, area and spiral construction is very important to have a controlled turbulence within the slurry flow for accurate size separation.

Mineral processing can be a major division within the science of Extractive Metallurgy. Extractive metallurgy continues to be thought as the science and art of extracting metals from other ores, refining them and preparing them to be used. Within extractive metallurgy, the main divisions inside the order they could most often occur are, Mineral Processing (or Beneficiation), Hydrometallurgy, Pyrometallurgy, and Electrometallurgy. The final procedures in the winning of metals have been in Physical Metallurgy the location where the composition and treating metals are varied to offer desired physical and mechanical properties.
Main Advantages of Spiral Cassifier:
- Adjustable weirs
- Sealed, submerged bearing
- Optional automatic lubrication system
- Rigid tank and substructure
- Wide selection of tank design
- Overflow collection box
- Number of industries serviced
- Single spiral range between 300 mm to two 200 mm
- Duplex spiral models 1 500 mm and two 200 mm
This spiral classifier can filter materials and send coarse materials towards the feeding mouth and discharge fine materials from your pipe. The seat from the machine features channel steel material, as the person is armor plated as well as the spiral axle is constructed of certain for durability. The machines lifting equipment can be utilized manually or electronically.
Spiral and Rake Classifiers
Mechanical classifiers including the spiral and rake classifiers operate in an identical fashion for the reason that both drag sediment and sand across the bottom of your inclined surface to some higher discharge point using one end with the settling chamber. The main difference within the two systems may be the mechanism where the settled material is moved in the inclined surface (see figure 11). Spiral classifiers are usually preferred as material doesn’t slide backwards which occur in rake classifiers if the rakes are lifted between strokes. And also this allows spiral classifiers to use at steeper inclines creating a drier product. The spiral classifier also produces less turbulence inside the settling pool enabling separation of finer material.
Washing:The sand is feeding in to the sediment pool from your feeding box, acting by rotating screw blade, the sand is turning and rolling and grinding one another to get rid of impurity and water-air layer around sand to facilitate de-water. The new eater rising current in the porous plate carry foreign matter to water surface and overflow the weir plate, to complete washing processing
De-watering: The sand with bigger density is sunken right down to tub bottom, the screw blade pushes this sand upwards, when passing through upper tub of a good length above level, the lake is draining into sediment pool from another drainage ditch, the de-watered sand is going in the discharging opening.

Classifying: Material classifying is realized by overflowing the non-needed fines, the controlling way is adjusting height of overflowing weir and adjusting speed of screw.
Spiral Classifier in Mineral Processing
In mineral processing, several unit operations must prepare and classify ores prior to the valuable constituents could be separated or concentrated then forwarded on to be used or further treatment. The joy of mineral processing been specifically given other titles including mineral dressing, ore dressing, mineral extraction, mineral beneficiation, and mineral engineering. These terms in many cases are used interchangeably.
