rake arms to a grit collection sump. At the grit collection sump, grit is pumped by dedicated grit slurry pumps to the grit handling equipment for further processing. Efficient detritus tank operation relies on the proper distribution of flow across the tank. Allowances are made for inlet and outlet turbulences as well as short circuiting
Meanwhile, global classifier fits a single model to the entire data; but the local classifier splits the input space and fits a model from the training set. Finally, we have a generative and discriminative classifier. The former classifies each instance to specific class and learn what mechanisms has been there for that class to be labeled to that instance.
Nov 15, 2019· Now, common classifiers in mineral processing plant are mainly mechanical classifier and hydrocyclone. Among them, mechanical classifier can be divided into spiral classifier, rake classifier, tank classifier and other types.

4) Global vs Local: A global classifier fits a single model to the entire data set. But this classifier doesn't fits if the relationship between attribute inputs and class labels are not effective. Local classifiers are divided the input into smaller regions. K-nearest neighbor is an example of local classifiers 5) Generative vs Discriminative: Classifiers that learn a generative model of ...
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 The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated; the settled material is thus slowly moved up the incline ...

The classifier section utilizes Rake Classifier, similar to that which has been successfully used in the metallurgical industry for many years. Virtually all of the plus 65 mesh inert solids are removed in this compartment. The grit is sprayed with water at the top of the screw to recover any remaining soda values before discharge.
The patented REFLUX® Classifier is one of our most advanced fine-particle, gravity-based separators, offering significant advantages in capacity, adaptability and efficiency. Incorporating the new "laminar high-shear-rate" mechanism, along with other advancements, our REFLUX Classifiers are both efficient and compact.
Mechanical classifiers (i.e. spiral and rake classifiers) are used when the particle sizes are considered to be too fine for screening. Hydro-cyclones (Cyclones) are used for de-sliming, de-gritting and thickening to separate at finer sizes than most screening and classification equipment. Separation and Concentration
The rake assembly is attached to the drive by means of a thick walled torque tube and slew ring arrangement. It incorporates a cone to direct solids across the thickener floor to increase the efficiency of the settling area. The rake blades, attached to the tubular, low drag rake arms are designed to the raking capacity required for the treated
Typically the Rake Classifier is used in conjunction with a Crossflow type Grit Detritor and together carries out the complete grit extraction process within a compact area. The system can be located either above or below ground level. The Rake Classifier is available as a design suitable for a civil or steel chamber construction.
