Rake Classifier

rake classifier mechanism. The rake classifier (Figure 9.18(a)) uses rakes actuated by an eccentric motion, which causes them to dip into the settled material and to move it up the incline for a short distance.The rakes are then withdrawn, and return to the starting-point, where the cycle is repeated.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 to the …

Spiral Classifiers and Cyclones Comparison of …

SPIRAL CLASSIFIERS Among the so called 'mechanicalclassifiers',spiral classifiers are the most used. There are several types ofmechanical classifiers, such as rake classifiers. Spiral classifiers, however, are the most employed inview oftheir constructive and operational simplicity. Here are their main advantages: they are extremely reliable;

Spiral

This spiral discovered by Bonaventura Cavalieri (1598-1647) creates a curve commonly known as a parabola. Another spiral, the hyperbolic spiral, conforms to the equation r = a/ θ. Another type of curve similar to a spiral is a helix. A helix is like a spiral in that it is a curve made by rotating around a point at an ever-increasing distance.

Screw-Spiral Classifier: Select, Size & Install

Different Types of Yarn and Their Properties

Fancy Yarns: A fancy yarn can be defined as one that differs from the normal construction of a single or doubled yarn by deliberately introduced irregularities in its construction.. The 'novelty' or 'fancy' yarns produce different textures and effects in the fabrics. Fancy yarns can be made from all natural fibers, all man-made fibers and their blends.
