Depending on the required coal fineness, there are two types of classifier that may be selected for a vertical roller mill. The dynamic classifier, which consists of a stationary angled inlet vane assembly surrounding a rotating vane assembly or cage, is capable of producing micrometer fine pulverized coal with a narrow particle size distribution.

#0183;#32; The circulating air is also used to classify the pulverized coal product prior to carrying it to the burners. The classifier, located on the top of a mill returns the oversize material back to the pulverizer but allows the propersized material to pass out of the mill to the burners. classifiers are critical in providing the desired quality of pulverized coal with the

There are two types of classifier: static and dynamic. Both use centrifugal force to carry out the classification function. In the static classifier the coal particles are passed through an angled vane structure. Heavier particles collide with the vanes, lose energy and fall back into the grinder.
Mar 01, 2020#0183;#32;The modern coal mill classifier, however, often has an impeller mounted close to the exit of the mill chamber. The impeller is a cage with a set of blades installed around its outer ring. It introduces a secondary classification by the collision effect in addition to the primary classification by centrifugal force [ [11], [12], [13] ].

#0183;#32;A dynamic classifier is retrofitted to a verticalshaft pulverizer by installing a duplicate upper pulverizer casing that houses the classifiers fixed and rotating vanes, motor, and drive...
In addition there is heated combustion air fed to the mill to transport the pulverised coal, and the secondary air supply as shown in Fig. 4. Grinding. The grinding function reduces coal fed into the mill into a dust with particles of the size required for combustion. There are two main types of mill in common use: the spindle type and the drum
#0183;#32;The classification performance of the air classifier in a vertical coal mill determines the size of pulverized coal particles. Thus, the classification performance will influence the ignition, burning, and burnout of the coal particle, and NO x formation in the furnace as well [,,, ].
These coal particles then pass through a classifier where the large particles get separated due to centrifugal action and are returned back to the grinding table. Different manufacturers use different type of rollers. Bowl mills or Raymond mills use tapered rollers. MPS mill use tire type rollers and are called roller mills.
pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to centrifugal classifiers. Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro duct is, however, separated and returned to the mill for further grinding.
In coal milling for power stations, a closedloop process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the recirculation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of recirculation loops within a mill
