In production, many concentrators more or less encounter the problem of obvious decline in the classification efficiency of spiral classifier, and the root cause of this problem lies in the disordered settlement of fine and heavy ore particles and coarse and light ore particles in the classification process, resulting in equal drop phenomenon, resulting in a large …

Message Chat Now. Spiral classifier is one of the common mineral beneficiation equipment, often used for classification, desliming, dewatering and other operations. There are three main factors that affect the classification effect of the spiral classifier: equipment structure, ore properties and operating.

The circulating load ratio is an excellent subject for study of classification system performance because it has long been recognized as such an important factor in ball milling efficiency. Results from the classical work of Davis (1925) are shown in Figure 2. Note that an increase in circulating load ratio from 150 to 500 percent yielded an ...

It is obvious that the floor area of hydrocyclone is significantly smaller than that of the spiral classifier. Usually, the hydrocyclone covers an area of only l/30 to l/50 to the spiral classifier. The equipment floor area requirement also limits the application of the spiral classifier to a certain extent. 3. Classification Efficiency.

to have the efficiency of the spiral classifier, but using cyclones as they simplify the . layout. 1.2. Objectives . This study aims to co mpare the use of cyclon es and spiral classifiers as.

In production, many concentrators more or less encountered spiral classifier classification efficiency significantly reduced problem, The root cause of this problem is that fine and heavy ore particles and coarse and light ore particles in the process of classification settlement disorder, resulting in the phenomenon of equal fall, so that a …

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 diameters (0.3 m to 2.25 m): Important in establishing a correct balance between overflow and raking capacity.

The spiral classifier is one of the common and key equipment in flotation separating process. We should know about its structure and working principles well before use it. 1. After the turning of helicoids, begin to fill the ore pulp and …

Efficiency of the cyclone operation is very low when there are significant variations in the feed rate. Conventional cyclone application range varies from about 0.005 to 0.3 mm, depending on the material to be classified. The so-called 'water only' or 'autogenous' …
