The Loesche coal grinding mill range is divided into two serial types: Small twin mills constructed to individual specifications (LM 12.2 D to LM 20.2 D), with table diameters from 1,200 to 2,000 mm. Larger mills with two, three and four rollers and modular struc-tures (LM 21.2 D to LM 43.4 D), with table diameters from 2,100 to 4,300 mm.
coal to e£t the classifier and enter a mill discharge chamber, connected to multiple coal pipes leading to the boiler. Oversized coal particles spiral down the classifier inner cone and discharge back into the grinding zone for further grinding through multiple-hinged reject doors located at the base of the cone.
RSG Inc, located in Sylacauga, Alabama U.S.A. specializes in fine powder technology. The company manufactures air classifiers, ball mills and stirred media mills for the production of fine, superfine and ultrafine powders for the mineral, mining, cement, lime, metal powder and chemical industries.
