4. Conclusions (1) The experiments indicated that Shi–Kojovic model fits the coal breakage process in Hardgrove mill well, with a mean R 2 of 0.967. (2) The form of Shi–Kojovic model can be used to simulate the relationship between t −75 and k(E cs − E min) in the case of identical feed size, with a mean R 2 of 0.952. Under the same k(E cs …

tion. This section further reduces the coal size by attrition and by impact of coal on the moving and stationary parts. There is no metal-to-metal contact of pulverizing elements. Oversized particles do not pass the rejector and remain in the pulverizing section for further size reduction. Properly sized pulverized coal, however, passes

Too high of a ratio (>2.5 hp/hammer) may result in poor hammer life. If the body or pin hole of the hammer are wearing before the hard facing or if there is excessive grooving on the hammer pins, increasing the hammer quantity is a common solution. The most common hammer patterns are in the range of 1.4:1 to 1.9:1 hp/hammer. Hammer …
