The cement manufacturing process involves several key steps, including preparing the raw materials, grinding the materials together, heating the newly formed clinker in a kiln, and finishing the cement with fine grinding. Some of the main ingredients used to make cement include limestone, clay, shale, iron, and sand. Different manufacturing techniques will use either wet or dry grinding, but each cement manufacturing process will culminate in heating and fine grinding to finish the product.

Preparing the raw materials is often the first step in the cement manufacturing process, and involves mining the limestone or obtaining safe industrial waste products. Drilling, blasting, and crushing machinery convert mined limestone to fragments about 0.39 inches about 1 cm in diameter, after which it is stored until needed. Crushing practices will sometimes be used on the other materials as well, especially if they contain large or irregularly sied fragments.

Grinding is the next step in the cement manufacturing process, and it can occur in either wet or dry forms. Wet grinding involves combining all of the materials in a mill with water and grinding it into slurry. In contrast, dry grinding processes combine and grind the materials without water, creating a substance known as kiln feed. Both types of grinding will yield material that contains an average particle sie of about 75 micrometers. After each process, the materials are further mixed for proper homogeneity and placed in storing units.

Heating occurs next, and it takes place in a rotary kiln that is fired at high temperatures. The kiln heats the clinker, the name for the dried material formed after the grinding process, until it reaches upwards of 2732F about 1500C. Afterward, the material is sent to a clinker cooler where the temperature lowers to a reasonable level, at which point the material can be stored once again.

Introduction For Cement Making

Introduction For Cement Making

The cement manufacturing process is completed when the cooled clinker is ground once again in a rotating finishing mill. A combination of gypsum and limestone will usually be added in small amounts to the heated cement during this last grinding step, and coloring agents can also be added here. The fineness of the finished particles will vary according to individual preferences, and the cement can reach a level of fineness where it will travel through liquid sieves. Completion of the finishing step means that the cement is ready to be packaged and distributed to builders and consumers.

The cement industry is the most important consumer of rubber waste. It uses 236,000 t of scrap tires 26 MJkg calorific heat and 290,000 t of industrial waste plastic waste, paper, textiles, etc., 22 MJkg caloric heat VDZ, 1999. Table VI.5.21 shows a comparison of components of traditional fuels and scrap tires.

The cost of treatment amounts to about 100t rubber waste. For imported coal, the cost is about 80t. Therefore, the cement industry charges about 80130t scrap tire to compensate for the difference Bilhard, 1997.

The cement industry is one of the main industries necessary for sustainable development. It can be considered the backbone for development. The main pollution source generated from cement industry is the solid waste called cement by-pass dust, which is collected from the bottom of the dust filter. It represents a major pollution problem in Egypt where around 2.4 million tons per year of cement dust is diffused into the atmosphere causing air pollution problems because of its sie 1-10 microns and alkalinity pH 11.5.

Cement by-pass dust is naturally alkaline with a high pH value and represents a major pollution problem. The safe disposal of cement dust costs a lot of money and still pollutes the environment. The chemical analysis for the by-pass dust is shown in Table 13.7.

Because of the high alkalinity of the cement by-pass dust, it can be used in the treatment of the municipal sewage sludge, which is considered another environmental problem in developing countries since it contains parasites such as Ascaris and heavy metals from industrial waste in the city. Although sludge has a very high nutritional value for land reclamation, it might contaminate the land. The safe disposal of sludge costs a lot of money and direct application of sludge for land reclamation has a lot of negative environmental impacts and is very haardous to health.

Introduction When mixing separate bags of cement and lime, hydrated lime must be completely wetted out in the mixing process or it will continue to absorb water after mixing. By following the proper mixing procedures, excellent board life, workability and sand carrying capacities are achieved with lime mortars. Materials The materials which could be used in a cement-lime mortar are defined in.
