Milling operations in various production processes are among the most important factors in determining the quality, stability, and consumption of energy. Optimizing and stabilizing the milling process is a non-linear multivariable control problem. In specific processes that deal with natural materials (e.g., cement, pulp and paper, beverage brewery and water/wastewater …

Therefore, measuring RH levels at 40% depth of the slab (20% depth if drying on two sides), is more representative of the overall humidity conditions of the concrete. Multiple factors can influence the amount of moisture in a concrete slab, thus contributing to high RH levels for up to six months or more after concrete is poured.

HeidelbergCement's new 1Mta grinding mill in Tema, Ghana. Ghacem, a subsidiary of HeidelbergCement, operates two cement grinding plants in the coastal cities of Tema and Takoradi, Ghana. With the commissioning of the new mill, Ghacem has increased its cement grinding capacity to 3.7Mta. Capital expenditure for the new project amounted to €16m.

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 ...

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.
