EIMCO K.C.P. Spiral Classifiers are mechanically the devices are powerfully built, and functionally they are versatile and flexible. Todays worldwide acceptance of EIMCO K.C.P. Classifiers for washing and dewatering pulps, and in closed circuit grinding is the result of many years of experience in solving wet classification problems.
The spiral dewaterers are able to handle large flows of effluents, offering a well dewatered mill scale product and a clear overflow . High flows and a low to moderate content of well defined solids like mill scales and slag are have proven to
Spiral jet mills are ubiquitous in the pharmaceutical industry. Breakage and classification in spiral jet mills occur due to complex interactions between the fluid and the solid phases. The study of these interactions requires the use of computational fluid dynamics for the fluid phase coupled with discrete element models for the particle phase.
The Spiral Jet mill has a simple structure with a classifying mechanism that utilizes the spiral airflow generated within the machine. It has the ability to ultra fine grind raw materials with low melting points to sizes of a few μm. The machine can be manufactured to correspond with GMP, CIP/SIP standards, making it a suitable machine for grinding a wide variety of materials for

Spiral Classifiers. The Spiral Classifier is available with spiral diameters up to 120. These classifiers are built in three models with 100%, 125% and 150% spiral submergence with straight side tanks or modified flared or full flared tanks. All sizes and models are available with single , double or triple pitch spirals.
09/07/2020· Spiral classifier is widely used in beneficiation plant to match with ball mill to form a closed circuit circulation path to distribute ore sand. Filter the material powder milled in the mill, and then use the spiral piece to screw the coarse material into the ball mill inlet, and the filtered fine material is discharged from the overflow pipe.
The classification equation requires knowledge of the radial air velocity and the tangential particle velocity. An extensive numerical investigation led to usable equations that take into account not only all of the above parameters but also the chamber mill diameter, the grinding chamber height, the classifier height, the outlet diameter and the number of nozzles.
06/08/2015· This will cause the classifier to stop and is known as being SANDED UP. If the speed of the rakes or spirals are too fast, too much will be pulled, out the top. This will increase the feed to the mill and result in an overload in either the mill or classifier as the circuit tries to process the increased CIRCULATING LOAD.
