The aim of this paper is to investigate the possible displacement of natural gypsum (CaSO 4 ·2H 2 O) in cement with an alternative setting retarder, such as the industrial byproduct derived from flue gas desulfurization process called FGD gypsum. These calciumsulfatebearing materials (CSBM), alone or in mixtures, were ground with clinker both in laboratory and industrial scale to examine ...

Roller mills are mills that use cylindrical rollers, either in opposing pairs or against flat plates, to crush or grind various materials, such as grain, ore, gravel, plastic, and others. Roller grain mills are an alternative to traditional millstone arrangements in gristmills. Roller mills for rock complement other types of mills, such as ball mills and hammermills, in such industries as the ...
The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...
The first industrialscale vertical roller mill for slag cement, an MPS 3750 C, went into operation in Hannover 25 years ago 1 and is still in operation today (Figure 3). The capacity of this mill ranges from 60t/h slag with 4100cm²/g to 70t/h CEM III A or 45t/h CEM III B with slag content between 5080% and fineness of 3600cm²/g and ...

Mortar is of fundamental importance for the building technology. It is used to bind together masonry units and ease the building process. Several building techniques evolved to take advantage of the capacity of mortars to improve cohesiveness and form sound structures. In this paper, I discuss how lime and gypsum mortars were employed from the Antiquity to the Middle Ages. Gypsum mortars ...
A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage [1]) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
