2021-10-27 A cement mill is a grinding machine that used to grind hard, nodular clinker from cement kiln into fine powder that is cement. At present, most cement is ground in ball mills. As the rapid development of construction, more and more cement are required. Grinding systems are either 'open circuit' or 'closed

Abstract. The characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closed-circuit is about 5% higher than that of the open

In this study, separator rejects of a closed circuit cement tube milling were dry ground in a 10-l pilot scale vertical stirred mill. Tests were done as open and closed circuit. The results were evaluated by size distributions, Blaine surface area of the products and the specific energy consumed during the tests.

The use of grinding aids in both open and closed circuit systems will improve the control of the grinding process, increasing the Blaine number (finer product). These advantages usually justify the cost of a grinding aid. But some cement manufacturers refuse to use grinding aids for economic reason.
