El proceso de secado por atomización: formación de gránulos y cinética de secado de gotas
(Sociedad Española de Cerámica y Vídrio, 2013-07)
Spray drying is a unit operation very common in many industrial processes. For each particular application, the resulting granulated material must possess determined properties that depend on the conditions in which the ...
Determinación de carbono orgánico en materias primas cerámicas en presencia de siderita, FeCO3
(CSIC-Consejo Superior de Investigaciones CientíficasSociedad Española de Cerámica y Vidrio, 2013-05)
La materia orgánica es una de las impurezas presentes en las materias primas utilizadas en la fabricación de pavimentos y revestimientos cerámicos. Durante el proceso de cocción, el carbono orgánico (Corgánico) puede ...
Densification of monomodal quartz particle beds by tapping
A study has been undertaken to determine how the mean particle size of monomodal quartz particle beds and the bed preparation method affect initial and final bed apparent density and the kinetics of densification by tapping. ...
Kinetic study of calcite particle (powder) thermal decomposition: Part I
In the first step of the firing cycle used to manufacture white-firing wall tile bodies, the calcium carbonate that is added, as a source of CaO, to the clay raw materials mixture used to form these bodies needs to decompose. ...
Environmental characterization of burnt coal gangue banks at Yangquan, Shanxi Province, China
The environmental characteristics of coal gangue dumps in Yangquan (Shanxi Province, China) were investigated. The amounts of coal gangue are very high in this coal region given the large coal production. As a result, ...
Fracture properties of spray-dried powder compacts: Effect of granule size
Inappropriate mechanical properties of spray-dried powder compacts lead to significant green product losses, entailing considerable costs in ceramic tile manufacture as well as serious environmental problems. In addition, ...
Variations in vanadium, nickel and lanthanoid element concentrations in urban air
The emission of trace metal pollutants by industry and transport takes place on a scale large enough to alter atmospheric chemistry and results in measurable differences between the urban background of inhalable particulate ...
Clinkers and cements obtained from raw mix containing ceramic waste as a raw material. Characterization, hydration and leaching studies
A clinker and a cement obtained from a raw mix containing ceramic waste as an alternative raw material were characterized in the present study. Their hydration, physical-chemical properties and leaching behaviour in different ...
Porous single-fired wall tile bodies: Influence of quartz particle size on tile properties
This study examines the effect of quartz particle size in raw material composition customarily used for the manufacture of porous single-fired wall tile bodies on the characteristics of the green tiles and on the thermal ...
Monitoring and possible reduction of HF in stack flue gases from ceramic tiles
HF (hydrogen fluoride) emission control is one of the critical environmental parameters in the firing of ceramic materials at peak temperatures higher than 1000 °C. In this study, in-stack concentrations of HF were monitored ...
