The Primary Spirals Separator. Feed from the splitter screen passes down into the gravity feed pump hopper and from there it is pumped to the static distributor above six triplex type primary spirals. As the pulp passes down these spirals; separaration of particles occurs according to specific gravity and the heavier minerals progress to the inner profile while lighter minerals are forced
These Mineral Spiral Separators are well acknowledged among the customers for their easy operation, high durability and cost effectiveness. Mineral Spiral Separator is a device used for separating slurry components by density or for a device for sorting particles by shape.
Gravity separation is an effective method for separating minerals of significantly different densities. It is an industrial method of separating two components from a suspension or any other homogeneous mixture where separating the components with gravity is sufficiently practical.

The enclosed spiral separator can save you money by effectively separating rounds from non-rounds and eliminating contaminants for recycled, reusable materials that saves you thousands. Not only does the spiral recycle your material but it also operates on gravity which saves you expensive energy costs.

Spiral separators; Reflux Classifier; In dense media separation a media is created with a density in between the density of the ore and gangue particles. When subjected to this media particles either float or sink depending on their density relative to the media. In this way the separation takes place purely on density differences and does
In Mineral Processing, the SPIRAL Classifier on the other hand is rotated through the ore. It doesn’t lift out of the slurry but is revolved through it. The direction of rotation causes the slurry to be pulled up the inclined bed of the classifier in much the same manner as the rakes do. As it is revolved in the slurry the spiral is constantly moving the coarse backwards the fine material

Spiral concentrators have been used globally in various types of mineral beneficiation plants. Particles are introduced in a slurry form at the top of a spiral and gravitate in a radial formation around a central axis, separation occurring mainly on size and density. Spiral concentrators
GTEK Spiral Separator Description. Spiral Separatos, which are also called sipral 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.
Spiral Concentrators (Flowing Film) Separation by density occurs as a result of primary flow and circulating secondary flow patterns that are created as the feed slurry travels along an elongated helical trough surface that spirals downward around a central axis.
US 3,235,079 discloses a method and apparatus for controlling spiral separators wherein the pulp density of the feed flow to a bank of spirals is measured by a pulp density meter, and, depending on the measurement from the pulp density meter, a splitter is positioned automatically to split the downstream concentrate stream to divert part of it

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
Jul 22, 2015 A density separator spiral demonstration at electra mining 2014. It's at the stand of Multotec.
Spiral Separators are used in the seed industry for separating good soybeans from splits or weed seed. Spiral Separators are often used in industrial applications such as separating metal abrasives, metal shot, ceramic beads, glass beads and other types of material.
Customers can avail from us Sand Spiral Separator in single, twin, triple or quadruple starts. Designed in 600mm diameter, our Sand Spiral Separator features seven turn units. Tonnage rating per start is 5.0tph depending on mineral type. Sand Spiral Separator is ideal for treatment of
To separate different particles by density difference, there are many approaches to achieve this aim, such as water-only cyclones, hindered-bed separators, spirals, small dense medium cyclones, et al.
Fig. 2 indicates the performance of the spiral separator under the effect of both feed pulp density and feed rate. It is evident that a pulp density in the range of 36 to 40% solids is near the optimum, in fact these data suggest that feed pulp densities >48% are detrimental to the performance. This is due to the higher apparent viscosity effect of
Description: centrifugal separation of sludge and water from mineral oil.The separator is designed for oils with a maximum density of 920 kg/m3 at 15°C. The maximum separation temperature for gas oil and marine diesel oil is +40°C, and for lubricating oil +70°C, since this is the max.
Classify your coal and heavy mineral streams by particle density or size. Developed by the world’s leading metallurgists, Multotec’s spiral separators achieve efficient mineral concentration with minimal energy and maintenance costs. Designed in response to real field challenges, for new or.
This is another variation of gravity separation, using density differences and centrifugal force; Figure 3.13. Originally known as Humphreys spiral (after the inventor) a wide range of devices are now available. A spiral concentrator consists of a helical conduit of semi-circular cross-section.
A history of gravity separation at Richards Bay Minerals result in blockage of the mouth organ splitters and inserts, affecting the even distribution of slurry feed to the separation surfaces. Cleaning the aforementioned splitters and slots was a tedious chore not looked forward to by the operating crews.
Dec 21, 2018 In a Dense Media Separation (DMS)/ Heavy Media Separation( HMS) plant, powdered ferrosilicon (an alloy of iron and silicone) is suspended in water to form a fluid near the density of diamond (3.52 g/cm3), to which the diamond-bearing material is added to begin the separation process of the heavier minerals from the lighter material.
Spirals; Spirals operate using density differences to concentrate material into respective high grade and low grade (waste) products. For spiral applications, the feed material must be less than 1mm and deslimed at 38µm should an excessive amount of fines be present.
