Spiral Separator. Spiral separators from Multotec separate / concentrate particles either by density or by shape. We supply wet and dry spiral separators, providing an essential classification solution to Africa's mineral beneficiation operations. Our spiral separators provide plant operators in coal, gold, iron ore, mineral sands.

Outotec Spiral Concentrator. Get an effective, low-cost device for the gravity beneficiation of ores. Outotec spiral concentrators are used in most applications, particularly for concentrating low-grade ores. Manufactured from lightweight, corrosion and abrasion-resistant materials, our spirals require minimal maintenance and.
In mineral processing: Gravity separation …forces—for example, centrifugal force on spirals or impact forces on shaking tables. Spirals consist of a vertical spiral channel with an oval cross section. As the pulp flows from the top to the bottom of the channel, heavier particles concentrate on the inner side of the stream, where.
Spirals are gravity concentrators and separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium. It has extremely good performance and effects in processing placer of beach, riverside, seashore and stream. “”.
Richards Bay Minerals constantly strives to add value to their existing process by investigating new technologies and new applications for older technologies and equipment. Two gravity separation units tested at the operations pilot plant facility were the Carpco wash-water spiral (9000 W) and the. Floatex density separator.

This invention provides an adjustable unit for a spiral separator seed processing machine. A set of fingers (one for each corresponding inner flight of the spiral separator) is attached to a unit. A set of these units mount on a rod, one of which is attached to each half of the spiral separator. The fingers act as seed dams.
Spiral Separator. Main Features. Spiral Grader has 4 types, high-dam single spiral, high-dam double spiral, submerged single spiral and submerged double spiral. It is widely used in beneficiation plants for classifying mineral sand with ball mill to form closed cycle, in gravity beneficiation plant for classifying mineral sand.
