The article describes hot-gas generator furnaces operating on coal and used in drying processes. Under analysis are special features of vertical furnaces working on pulverised coal and furnaces that burn raw lump coal on a moving grate. The basic technical-and-economic ...
The French engineering company Icer Groupe Snef cites examples of its completed cement plant modernization projects, reports on the measures involving reconstruction of electrical equipment and upgrading the production technology.
The article describes the sequence of the development and introduction of an automated system of quality control and laboratory. It shows the effect of the system on ready product quality control at every production stage.
The article describes ECS/CemScanner - a new kiln shell temperature control system that includes software, an IR scanner and data processing devices. In addition to providing a picture of the temperature distribution and information on the luting status, this system ...
The process of gunning is well known in the cement industry. In recent time the refractory producers have improved their gunning materials in the field of low (or even no) cement mixes. These materials could only be processed by casting or shotcreting. By means ...
A study was made of the capability of lithium-silica-containing solutions obtained by interaction between aqueous colloidal dispersion SiO2 and LiOH to inhibit alkali expansion of cement-sand solutions with reactive filler. It was established that the inhibiting effect ...
In the course of laboratory and industrial investigations we have tested that reducing slag as well as of the setting of the sulfatization degree of raw meal. In clinker it is possible to decrease the chromate content during manufacture and firing clinker. It has been t...
A study was made of hydration of mixed cements including Portland cement clinker and some silica-containing materials. Differences were identified in the processes of hydration and strength growth of cement stone depending on the type of additive. The differences are in...
Admixture of LiF (2%) into the raw mix allows to produce clinker containing alite (KN=0,9; n=2,19; p=1,29) at the temperature of 1100 °C with compression strength 42 MPa.
