Wei et al. calculated the air classifier efficiency in a ZGM coal mill by the fitting method, and its classification mechanism was revealed [11].
The rotary classifier can meet the requirements of fineness for coal powder when burning the low-Nox, which is good to environment. When the evenness index of coal powder is increased to 1.3—1.4, without changing the fineness of coal powder R90, the R200 falls down.

4 zgm roller vertical mill 41 application for all gradesranging from hard lignite to anthracite zgm vertical mills have a firmly established reputation for economy in the preparatory processing of coal they are used mainly in direct pulverized coal firing systems or steam boilers in power plant.
Classification tests of coal samples were carried out in a static classifier of a vertical spindle mill to investigate the effect of size and density on particle segregation [15,16,17,18,19,20]. Currently, the fuzzy inference approach is increasingly commonly used in modeling various technological processes.
The vertical spiral stirring mill can be used for grinding and leaching at the same time. Suitable for the second stage grinding, sulphide ore fine grinding and tailings utilization, can be economically grinding ore to -400 mesh more than 90%-95% can be fine grinding ore, ore can be grinding to -10 micron or less.

Wei et al. calculated the air classifier efficiency in a ZGM coal mill by the fitting method, and its classification mechanism was revealed [11]. With the help of numerical study, gas–solid properties, like flow path, particle motion, swirl velocity and so on, were demonstrated during classification process within air classifier.
Coal mill classifier EVT Engergie und Verfahrensteckhnik Normally,classifierswith rotatingclassifyingblades are used for fine particles of pulverizedcoal, corresponding approximately to <10% oversize on an 0.09 aperture width test sieve.
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. There is minimal metal-to-metal contact of the grinding elements in the BTM resulting in very little wear and low maintenance.
This study shows the performance of a currently running vertical roller coal mill (VRM) in an existing coal-fired power plant. In a power plant, the coal mill is the critical equipment, whose ...
Abstract：To realize rapid and effective evaluation and control on the performance of an MPS medium speed coal mill, a mathematical model was built up for the grinding, drying, separation and circulation process, where the MPS medium speed mill was divided into following five parts, such as the bowl zone, grinding zone, initial separation area, classifier and the …
Results show that at high milling output, when the rotor speed is increased, the reduction of pulverized coal fineness R 90 would be slowed down; the appropriate rotor speed is about 67.5 r/min, and high rotor speed would result in rapidly increased separation power consumption, but slightly improved pulverized coal fineness. Whereas, at low ...
