Dec 24, 2016· Grinding. The clinkers as obtained from the rotary kiln are finely ground in ball mills and tube mills. During grinding, a small quantity, about 3 to 4 percent, of gypsum is added. The gypsum controls the initial setting time of cement. If gypsum is not added, the cement …
Dec 01, 2019· 1. Introduction. Clinker milling is the last step in production of Portland cement. Nodular clinkers produced in a rotary kiln in a cement plant are ground together with gypsum into a fine powder of particle size less than 100 μm and with a surface area of 330–380 m 2 /kg for production of ordinary Portland cement ().The fineness of the particles is a critical aspect that governs the ...
The type of mill also can affect the selection of grinding media. Ball Mills use very large media while Attritors employ media ranging in size from 1/8" to 1". Horizontal mills require much smaller media, as small as 0.05 mm to 2 mm. To read detailed specs and submit a quote, click here for our metallic media or here for our non-metallic media.
