Energy-Efficient Technologies in Cement Grinding

23/10/2015  1. Introduction. Cement is an energy-intensive industry in which the grinding circuits use more than 60 % of the total electrical energy consumed and account for most of the manufacturing cost [].The requirements for the cement industry in the future are to reduce the use of energy in grinding and the emission of CO 2 from the kilns. In recent years, the production

Cement - Extraction and processing Britannica

There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as “ clinker,” together with some 5 percent of gypsum (to control the time of set of the cement).

Cement mill - Wikipedia

Early hydraulic cements, such as those of James Parker, James Frost and Joseph Aspdin were relatively soft and readily ground by the primitive of the day, using flat millstones. The emergence of Portland cementin the 1840s made grinding considerably more difficult, because the clinker produced by the kiln is often as hard as the millstone material. Because of this, cement continued to be ground very coarsely (typically 20% over 100 μm particle diameter) until better grinding became availabl

Grinding (abrasive cutting) - Wikipedia

Cylindrical grinding (also called center-type grinding) is used to grind the cylindrical surfaces and shoulders of the workpiece. The workpiece is mounted on centers and rotated by a device known as a lathe dog or center driver. The abrasive wheel and the workpiece are rotated by separate motors and at different speeds. The table can be adjusted to produce tapers. The wheel head can be ...
