cost and less space required have caused operation with spiral classifiers to becomerestricted. The application range ofspiral classifiers range is 0.070 to 1 mm, depending on the material to be separated. Compared to cyclones, spiral classifiers cover a coarser separation range. Autogenous cyclones also cover a coarser range, replacing

They are also used, in some installations to assist ...

The design provides adequate retention time for optimum slaking efficiency. EIMCO-K.C.P Slaker Classifiers are available depending on the design of the hot lime facilities. The recommended Slaker Classifier combines the slaking action, classifying and grit removal in a single, rugged unit.

Classifier. The Spiral Classifier used for the study was manufactured by Nick and Paul. 2.2 Designing of Test Works Prior to test work design, visit to the oxide plant at Ghana Manganese Company (GMC) were made with the aim of getting acclimatize with the current operations at the plant. The Spiral classifier was operated in batch mode.

A Conveying spiral is mounted within the trough to discharge settled materials above the level of the pool level. Removal of large, abrasive materials by the Classifier helps succeeding equipment perform better and last longer. Design and Construction Features. Low initial cost on operation and maintenance.

Because users' needs vary so greatly, the Classifier is available in a wide range of spiral diameters and pitches, tank shapes and lengths allowing exact compliance with each user's classification requirements. Spiral …

Spiral concentrators (Fig. 5.2.3) are devices to separate different solid components in slurrybased upon a combination of the solid particle density, as well as the particle's hydrodynamic properties (e.g., drag).The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid …

The spiral classifier can be divided into three types: high dam type, low dam type and submerged type. 1). High Dam Spiral Classifier. The high dam type spiral classifier means that the overflow dam is higher than the spiral axis of the spiral, but lower than the upper edge of the spiral at the overflow end.
