RAKE short for Rapid Automatic Keyword Extraction algorithm, is a domain independent keyword extraction algorithm which tries to determine key phrases in a body of text by analyzing the frequency of word appearance and its co-occurance with other words in the text.
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 ...

Reciprocating rake classifiers. Reciprocating rake classifier are described by characteristics such as component materials, operating temperature range and durability.
An extensive series of tests was carried out on a ball mill-rake classifier circuit in the New Broken Hill Consolidated Ltd. concentrator. The data were used to develop a mathematical model of the operation of a rake classifier and this model has been used in the simulation of the performance of a ball mill-rake classifier...
Rake, spiral, and bowl classifiers use mechanical action to dewater, deslime or separate coarse bulk materials from finer materials or liquids. Drag classifiers consist of a chain-link conveyor or endless belt that is dragged through a solid-liquid mixture. Rake classifiers lift solid-liquid mixtures up onto a plate with a screen or rake.
spiral classifier for mineral processing. Descriptions. We produce high weir type, single and double spiral, and immersed single and double spiral classifiers. Our spiral classifiers are widely used in the distribution of ore in closed circuits with ball mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal ore-dressing, and de-sliming and dehydrating in washing.
The Tuke & Bell Rake Classifier is a multiple-rake reciprocating mechanism, mounted within a cleaning channel, which is a narrow, continuously sloping ramp. The reciprocating action moves the grit, up the ramp towards a discharge point above top water level.
Definition of rake classifier. A type of mechanical classifier utilizing reciprocal rakes on an inclined plane to separate coarse from fine material contained in a water pulp, overflowing the fine material and discharging the coarse material by means of an inclined raking system.
FL's DorrOliver® rake classifier is a rectangular classifier tank with an inclined channel, and equipped with a reciprocating raking mechanism which transports the settled solids towards the upper discharge end. Get Price; used sand screw classifier usa .
Rake Classifier. The Tuke & Bell Rake Classifier is a multiple-rake reciprocating mechanism, mounted within a cleaning channel, which is a narrow, continuously sloping ramp. The reciprocating action moves the grit, up the ramp towards a discharge point above top water level. At this point the grit is free of water, which assists easy and ...

The Dorr Company had been losing money because of faulty classification of gold ore and Dorr's solution was to invent a reciprocating rake classifier to replace inadequate classifying cones. It was accepted virtually immediately and subsequently marketed to other western mills.
Classification: Humanoid The Rake is a creature believed to be a humanoid in appearance, with several references in folklore and horrific urban legends, originally appearing on the internet on Creepypasta. The creature reportedly attacks humans due to unknown reasons and often causes its victims great psychological trauma. Several theories as ...
The undersize was de- watered in a rake classifier, and the rake product was tabled to reject a tailing and recover an enriched silli- manite product, which was dewatered and sent to flota- tion. Analytical description of the unsteady settling of spherical particles in Stokes and Newton regimes. Rake classifiers work in an analogous way as ...
A wide variety of rake classifier options are available to you, There are 7 rake classifier suppliers, mainly located in Asia. The top supplying country is China (Mainland), which supply of rake classifier respectively. Rake classifier products are most popular in …
Sand Classifier SA Sand Classifier SA separates, dewaters & conveys sand and heavy particles from water. Street sand, filter sand and similar materials can be handled.
The grit rake classifier lifts the grit out of the chamber for disposal. Our grit rake classifiers can be manufactured from a range of materials including steel box section or angle iron. The grit rake is welded together, shot blasted and cleaned.
We manufacture ultra-modern Rake Type Lime Classifier that is used grit removal equipment for the sugar mill. This grit removal equipment is capable of separating even the micron size of grit. Our lime station equipment ensures low mud volume and less scaling at the evaporator.
The rake classifier. It is a mechanical classifier utilising rakes. The rakes are actuated by an eccentric motion to dip into the settled material and move it up the incline for a short distance. The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated; the settled material is thus slowly moved up the incline ...
Thickeners and clarifiers use slowly rotating rake arms to separate solid particulate. A liquid feed with suspended solids is fed into a tank with a diameter of 5 to 500 feet. As the particles settle, angled rake arms move the concentrated slurry toward the center of the tank, where it is removed.
A bowl and rake classifier is typically used to separate coarse and fine particles of granular material temporarily suspended in water. The coarse particles settle to the bottom of the vessel and are scraped by a set of blades.
A classifier of the character described, comprising a tank for holding pulp having an inclined bottom and a rake operable for raking action over the bottom, the rake having flat vertical blades perforated to allow pulp to pass therethrough and to keep the pulp in a loose flowing condition, whereby the denser and smaller particles are made to ...
Jul 23, 2017· Document/Text classification is one of the important and typical task in supervised machine learning (ML). Assigning categories to documents, which can be a web page, library book, media articles, gallery etc. has many applications like e.g. …

13.2.2. Rake Classifiers. When rakes are used in place of spirals, the classifiers are called Rake classifiers. These are less common than spiral classifiers. The rakes consist of one or more parallel lines of steel plates that hang from a central shaft or shafts. The plates are hinged onto these shafts and have a reciprocating movement.
Lime Slaker : Lime slaker is divided into two sections, the Mixer or slaking compartment and the cleaning or degritting compartment. The former consists of a cylindrical tank with a motor driven Mixer; the later is typical Classifier consisting of a sloping rectangular rake.
A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and (or) thickening. Concentrated impurities, discharged from the bottom of the tank are known as sludge, while the particles that float to the surface of the liquid are called scum.
