Fine coal dry classifiion and separation | SpringerLink

· Coal is currently cleaned with a minimum of size reduction; fine particle processing, recovery and tailings disposal are major problems; and adequate water resources are not always available. Twothirds of China's coal is loed in arid areas. Hence, dry separation provides an alternative approach. Of the dry coal separation methods available, air densemedium .

Air Classifier

The classifier's focus: its classifiion effect. An air classifier divides material flow into two parts. One of them consists of fine material, the other one of coarser parts. Centrifugal, gravitational and flow forces impact on mass elements which are of di"erent sizes and use natural laws to bring about classifiion.

Classifying

With our „standard" ultrafine classifier, CFS, fine powders can be cleanly classified. High performance classifiion and efficient results are valid for both coarse material and the separation of fines. Available for finenesses from 10 to 250 µm (d97). Machine sizes available for gas volume from approximately 50 to Nm³/h.

Research on Classifiion of FineGrained Rock Images ...

· Rock classifiion is a significant branch of geology which can help understand the formation and evolution of the planet, search for mineral resources, and so on. In traditional methods, rock classifiion is usually done based on the experience of a professional. However, this method has problems such as low efficiency and susceptibility to subjective factors.

classifier for fine coal

Normally, classifiers with rotating classifying blades are used for fine particles of pulverized coal, corresponding approximately to 10% oversize on an aperture width test sieve. However, if coals needing such finenesses are burnt only from time to time, the use of such a classifier is uneconomical with regard to investment costs.
