KHD Humboldt Wedag Roller Presses offer rollers with appropriate wear protection for almost all applications in the cement and minerals industry. The two-part roller consisting of shaft and tire allows for economical surface replacement, single part rollers are used for high temperature grinding.After the mill was in operation for over 10,000 hours the roller and table wear rates have been measured 2 times, once through each method. Described above, cement vertical grinding roller segment rotation and rewelding of both the table and roller liners. The actual wear rate for both the roller and table liners before hardfacing was 0.30 g T.
When grinding cement, the ball mill has a yield of 300~1000g t, and the grinding system of the roller press has a yield of 0.5g t, so it can meet the requirements of white cement. Low noise. The ball mill noise is above 110 dB, while the roller press is about 80 dB.Grinding rolls for vertical mills in the cement industry The operating parameters of vertical mills are seldom altered once optimum productivity is established. But efficiency improvements – and therefore cost savings – can still be achieved with developments in metallurgy of the grinding element.
