Spiral Classifier and Spiral Sand Washing Machine
A spiral classifier and a spiral sand washing machine are used to separate solid particles in slurry based on their sedimentation speed. Typically, the spiral classifier works in conjunction with a ball mill to create a closed-circuit system, where coarse particles are returned to the ball mill for further grinding.
Importance of Spiral Classifiers
The classifier significantly impacts the mill's efficiency, making the selection of grading equipment crucial in the beneficiation process. Spiral classifiers are available in single and double spiral designs, based on the number of screw shafts.
Scope of Application
Spiral classifiers are widely used in ore dressing plants and ball mills to form a closed cycle, splitting ore sand. They are also used in gravity concentrators to grade ore sand and fine mud, and for particle size classification in metal beneficiation processes. Additionally, they are employed for desliming and dehydration in ore washing operations. These machines are characterized by their simple structure, reliable operation, and ease of use.
Applications
Ore Dressing Plants: Forming closed cycles with ball mills and splitting ore sand.
Gravity Concentrators: Grading ore and metal, and classifying pulp by particle size.
Desliming and Dewatering: Used in ore washing operations for removing slimes and excess water.
In summary, spiral classifiers are essential for improving mill efficiency and are widely used in various mineral processing applications due to their simplicity, reliability, and ease of operation.

Working Principle of Spiral Classifier
The spiral classifier operates on the principle that solid particles have different settling velocities in a liquid due to variations in their size and specific gravity. Fine ore particles, which settle more slowly, float in the water and flow out, while coarser particles, which settle faster, sink to the bottom of the trough.
Separation Process
Sedimentation: The difference in sedimentation velocity causes fine particles to float and overflow, while coarse particles settle at the bottom.
Movement and Scrubbing: The coarse particles are pushed forward by a spiral impeller, and as sand and gravel move, they are scrubbed by water flow to wash and separate impurities and soil.
Tailings Discharge: The cleaned material falls onto the front end of a tailings dry discharge screen. The vibration device generates an exciting force, causing the material to move linearly and discharge from the port.
Moisture Removal: Moisture from the material falls through the screen mesh into the screen box, entering the back-end storage tank via the overflow device.
Cyclone Separation: The slurry pump then pumps the material into a cyclone separator. Here, centrifugal force concentrates the material, and qualified materials proceed to a dewatering screen.
Dewatering: The drainage device removes excess water, and the remaining wastewater is directed to a water repellent device for final discharge.
Summary
The spiral classifier efficiently separates fine and coarse particles based on their settling velocities in water. Through sedimentation, scrubbing, and vibration, it cleans and sorts the material, ultimately removing moisture and discharging the wastewater. This process ensures effective classification and preparation of materials for further processing.
