Cement milling and gypsum dehydration. Because the cement gets hot due to the heat generated by grinding, gypsum can be partly dehydrated, forming hemihydrate, or plaster of Paris - 2CaSO 4.H 2 O. On further heating, hemihydrate dehydrates further to a form of calcium sulfate known as soluble anhydrite (~CaSO 4). This is calcium sulfate with a .

Cement Material Temperature Control In Cement Ball Mills, 13 · Ball mills are predominantly used machines for grinding in the cement industry. Although ball mills have been used for more than one hundred years, the design is still being improved in order to reduce the grinding costs.
Tip one: Play sand can be a contractor’s best friend when it comes to concrete grinding and polishing. Play sand is a great thing to keep handy as an abrasion aid when using a concrete grinder. It keeps the diamonds dressed and cooled while acting as a secondary abrasive to assist in the actual grinding process.

Wet Cutting (Water Spraying) - This engineeringcontrolhelps to eliminate silica dust from ever becoming airborne and is the most efficient method of dustcontrolin concrete cutting and grinding. Saws and grinding equipment should be fitted with a wet-cutting port, or alternatively, a portable water tank or cart can be supplied.
Typically, for every 1 F (0.6 C) reduction or increase in the initial concrete temperature, the maximum concrete temperature is changed by approximately 1 F (0.6 C). As an example, to reduce the maximum concrete temperature by approximately 10 F (6 C), the concrete temperature at the time of placement should generally be reduced by 10 F (6 C).
Evaporative Cooling-Temperature Control Evaporative cooling uses the process of evaporation to control the temperature in an environment. A high pressure pump system and nozzles spray atomized water into the air. The atomized water droplets, which are less than 10 micron, convert quickly to a gas as they absorb the heat from the air.
Temperature control Heat generated in the grinding process causes gypsum (CaSO 4 .2H 2 O) to lose water, forming bassanite (CaSO 4 .0.2-0.7H 2 O) or 纬-anhydrite (CaSO 4 .~0.05H 2 O). The latter minerals are rapidly soluble, and about 2% of these in cement is needed to control tricalcium aluminate hydration.
