How to Grind Concrete: Tips for Using a Concrete Grinder

Oct 12, 2021  Using a concrete grinder: Technique matters. When grinding concrete, take your time and allow the machine to do its work. If you move too fast, odds are you’ll end up redoing some areas. The way you move the grinder depends on the type you’re using. Single disc or duel-disc rotary grinder: Swing the machine from side to side.

Low temperature cement grinding - Page 1 of 1

Re: Low temperature cement grinding. Hi Gio, Hope this is same Gio I met Natal SA. Normally when clinker grinding in verucal mills, the mill outlet temperature is around 80-85 deg C only. What I feel is try to optimise the dam ring height of the mill to have proper partical size distribution. This will help to increase the strength.

Cement Milling - Understanding Cement

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 mill - Wikipedia

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 γ-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. If more than this amount forms ...

reduce temperature in cement mill

Approach to High Temperature of Cement Ball Mill. You can make sprinkler measures in the grinding body, generally in fine grinding compartment spray. 1% to 2% of the cement production is atomized water, which can increase the yield of 10% to 20%, and greatly reduce the outlet temperature of cement ball mill, so as to improve the collection status of ventilation gas dust.

Cement Manufacturing Process: How the Cement is Made?

3. Grinding: The clinkers as obtained from the rotary kiln are finely ground in ball mills and tube mills. During grinding, a small quantity, about 3 to 4 per cent, of gypsum is added. The gypsum controls the initial setting time of cement. If gypsum is not added, the cement would set as soon as water is added.
