type of mill for wood pellets, both in conversions and new plants. Vertical spindle mills have a bowl or table, which the fuel rests on, forming a grinding bed. The fuel in this bed is crushed between the bowl or table and large steel balls or rollers. This type of mill is very popular in power plants that burn bituminous and sub-.
Whether in cement works, steel mills or power plants, whether direct or indirect firing: Our ATEX-certified coal grinding plants have proven themselves internationally in all areas of application. We also develop custom-tailored concepts for closed-down ball mills in the cement industry. By equipping them with additional.
Each mill pulverizer is responsible for about 130 megawatts of power. When the coal quality is good, the unit can run at full capacity on five pulverizers. Therefore, in the event of a failure, the impact on production is minimal assuming a second pulverizer does not fail. The plant maintains two gearboxes as spares because.
