Spiral separators operate on gravity only. Product is loaded in the hopper, or direct feed tube on a single spiral. The material flows over an adjustable cone and divides the material evenly onto the inner flights. With increasing speed, the round material will separate and roll off the inner flights onto a larger outer flight and then exits a ...
The spiral classifier, recently, has emerged as the most effective gravity separator since its introduction.

Operates by gravity....These Double separators contains two units of spirals fed ...
Principle of Separation. Spiral separation is based on the specific gravity difference present in a feed mineral suite. When fed a dilute pulp mixture of minerals of different specific gravities, the lighter minerals are more readily suspended by the water and attain relatively high tangential velocities so that they climb toward the outer rim of the spiral …
Spiral separators, or spirals for short, are a versatile method of gravity separation that can deal with a comparatively wide size range. Separation is achieved as a result of centrifugal forces induced by slurry running down the spiral, which forces lighter minerals to the outer bend whilst heavier minerals stay closer to the central axis of the spiral.
During separation, the slurry enters the spiral through a feed box and then flows on to the spiral surface. As the slurry travels down the spiral, mineral grains settle and sort according to size, shape, and specific gravity. …
The spiral concentrator is one of the most common gravity concentration equipment used in the mineral processing to recover heavy mineral from gangue minerals, perhaps their …

Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal, drag or buoyant forces). The resistance to motion, known as drag force, by a medium such as heavy media, water or even air, is one such force.
