Classification performance of model coal mill classifiers

01/03/2020 The first generation of the coal mill classifier used static guide vanes to produce a swirling flow to classify the particles by centrifugal force [,,,,, ]. The modern coal mill classifier, however, often has an impeller mounted close to the exit of the mill chamber.

Coal Mill an overview ScienceDirect Topics

In coal milling for power stations, a ‘closed-loop’ process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.

Patented Classifier Cone Extension Mill Modernization

The weight of the accumulated reject coal trips the Flapper Door and releases it for regrind. Air flow studies show that coal released from the Flapper Assembly falls into the air stream and can be carried back through the classifier to be rejected again, thus short circuiting the classifier process. In some cases the Flapper Door sticks open allowing coal to blow back through the door. SAS

B ecause the N.N.Zoubov Engineers SMCE Air Swept classifier is installed independently near the mill itself, it is adapted for any type of vertical coal mill without any need for changes in the mill itself, other than providing for the reintroduction of the clean tailings into the mill. In some cases the static separator installed in the mill can be maintained, completely open.

The advantage of this kind of configuration form is to make full use of the height difference between the ball mill and the classifier, and directly feed the large-grain ore into the classifier, which reduces the wear of the pump caused by the large-grain ore. The disadvantage is that the screening effect of minerals is unstable due to the frequent blockage of the screen hole, the amount of

In addition to raising the coal temperature inside the mill for drying and better grinding, the same air works as the transport medium to move the pulverized coal out of the mill: it travels through the annular space between the fixed trunnion tubes and the rotating hot air tube onwards to the classifier. Coal-laden air passes through double cone static classifiers, with adjustable classifier
