1. Crushing stage: jaw crusher, hammer crusher. The 0-150mm material enters the 200*300 jaw crusher through the trough feeder, the crushed material is transported to the hopper through the belt conveyor, and feed to the 600*800 hammer crusher by the electromagnetic vibrating feeder for secondary crushing.
There are a number of design considerations which influence the selection of a suitable pitch and trough shape for a new spiral separator.

The Enclosed Spiral Separator ensures durability due to its 14 to 16-gauge galvanized steel, and you can configure it from 1 to 24 core units. As your operation grows and changes, this product can as well. This separator can effectively separate and eliminate splits, bad seeds, chaff, hulls, weed seeds and debris.
A number of features have been incorporated into the design of spiral separators. These include: Feed boxes, slide splitters, pivotal splitters, water splitters, repulpers and …
Understanding the influence mechanism of the partial cross-sectional geometry of a spiral separator on the flow field characteristics and particle separation performance is conducive to the design of a combined cross-section profile. The impact of the trough slope in the inner and middle troughs on the flow field characteristics and particle ...
Records indicate that spiral separators have been utilised in mineral separation for over 100 years. The Spiral's predecessor, the sluice, has been in use for centuries in different forms and a spiral can be thought of as a sluice wound around a column. The spiral separator is distinguished from the
The gas/liquid spiral separator, a key component in the compressed air system, was used to remove liquid and oil from gas stream by centrifugal and gravitational forces. To optimize the design of the separator, the relationship between the performance and structural parameters of separators is studied. Computational fluid dynamics (CFD) …

A spiral separator consists of an open channel that wraps around the central supporting column. The number of turns (n) varies from 3 to 10. ... Standard wall function is suitable for the used mesh with such small cells near the solid walls. The water phase on spiral separator is assumed to have constant physical properties.

One of the objectives is to obtain the most appropriate turbulence model for the present problem. The present model is validated using the experimental data of Holtham et al. [17–19]. 2. Spiral separator description 2.1. Geometry of spiral separator A spiral separator consists of an open channel that wraps around the central supporting column.
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 …
Finally, concentrate of big density and big particle size gets discharged from the inside edge of spiral chute. The tailing of small density and small particle size gets discharged from the spiral chute. The spiral chute is the common equipment for the classification and separation of fine particled minerals in the beneficiation factory.

In a centrifugal sand separator, the water rushes through the device and the centrifugal forces sling large particles, sand, debris, and sludge outward to the separator wall and downward in a spiral motion. Gravitational force pulls the separated solid particles downward past the spin trap plate into the solids holding chamber.
The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails.

Working Principle. Spiral Separators, which are also called Spiral Concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium. The heavy frictional forces slow their velocity. As a result, faster particles higher up in the flow.
