Coal Mill Classifier Repair PROBLEM The Coal Mill Classifier Cone directs the pulverized coal out of the mill and into the furnace. Hot air, from the air side of the air preheater, is pulled through the coal mill by the exhaust fan (refer CH-801) picking up the fine coal dust and feeding it to the furnace. The classifier cone is generally

The classifier cone is generally lined with thick Alumina wear plates to protect the cone from the abrasive coal particles. With time, these plates wear down and must be replaced. Replacement is done both in the field and at the manufacuterer. The replacement wear plates are metal backed with a hole in the center to allow welding to the metal classifier cone.
The SAS Mill Modernization program can include available patented SAS modernization technology, rebuild / installation and then fine tuning of the mill. The first phase of this program should include a complete Mill inspection and accurate coal pipe testing which will establish baseline data. The information gained will include coal pipe balance, coal fineness, air/coal
The first phase of this program should include a complete Mill inspection and accurate coal pipe testing which will establish baseline data. The information gained will include coal pipe balance, coal fineness, air/coal ratios, as well as the condition of the grinding components, mill throat, classifier, springs, and other components.

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.
classifier is mounted above the grinding zone. The feeding device for fresh material is arranged in this area where the fresh feed is also mixed with the grits rejected from the classifier (see Figure 1). The main difference between an MPS mill for solid fuels and other MPS mills lies in its pressure-shock resistance. Mill and classifier housing,
Mar 01, 2020 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 .
