Water Spray in Cement Mills. Water spray installed generally in second compartment of ball mill to control cement temperature. Cement discharge temperature should be kept below about 110 o C but, the same time should allow some 60% dehydration of gypsum to optimize cement strength without excessive false set. Water spray is controlled with mill outlet gas or material temperature.
Cement Mill Temperature Control Fute Machanic . Water Injection In Ball Mill Cement Grinding Vdchari Water Injection in Ball mill for cement grinding Ball mill generally produces a lot of heat as the material advances in the mill the temperature increases If the temperature increases beyond 110 degree different problems are .
Fresh Concrete temperature should not be more than C Ensure using of ICE and Chilled water in wet concrete to control the fresh concrete temperature Proper quality checks require at site
Too much heat reduces the final concrete strength. Selecting an appropriate curing process helps in temperature control during hydration Methods of curing Concrete can be kept moist and often at a favorable temperature by any of three methods: Maintaining the presence of mixing water during the early hardening period. Methods used include

Mar 23, 2018#0183;#32;Two approaches, or a combination of both, can be taken to control the temperature during the dormant and strengthgain phases of the hydration process. One approach is to control the surrounding elements or mix constituents temperature. The second approach is to optimize the mix design. Concrete Temperature Control During Mixing and Curing

Temperature control. Heat generated in the grinding process causes gypsum (CaSO 2 O) to lose water, forming bassanite (CaSO 2 O) or anhydrite (CaSO 4.~ 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
concrete temperature development during earlyages. A model to predict initial and final setting of hardening concrete is presented, and calibrated, with data collected under laboratory and field conditions. The effects of concrete temperature, different cements, and mineral admixtures on the initial and final times are characterized.

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 8085 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. Raj. Reply
