Most plants use compressed air to agitate the powdered meal in so-called air-fluidized homogenizing silos (using 1.1-1.5 kWh/t raw meal). Older dry process plants use mechanical systems, which simultaneously withdraw material from 6-8 different silos at variable rates (Fujimoto, 1993), using 2.2-2.6 kWh/t raw meal.

Pneumatic homogenization of raw mix. In the past, the wet process was preferred for the production of high quality cement, since homogeniza­tion of the slurry resulted in a thorough mixture of the raw material components. Progress in the fields of aerodynamics and pneumatics has enabled the cement industry to pneumatically homogenize the dry ...

raw meal homogenizing silo cement industry T02:10:38+00:00 RAW MEAL HOMOGENIZATION AND STORAGE IN CEMENT . There are two basic homogenizing processes for dry raw meal ie Batch process and continuous process In the batch process, at least two pairs of double deck silos, each consisting of a blending silo at the top and …

Each process production line should be equipped with 1 or 2 continuous homogenization silos, and the height to diameter ratio should be 2 to 2.5. The raw material moisture in the storage should be controlled below 0.5%, and the maximum should not exceed 0.8%. Do not mix large particles of raw materials, abrasive bodies and other debris in the ...

The invention relates to a cement raw meal homogenizing silo. According to the invention, the top surface of a base of the cement raw meal homogenizing soli is an inverted cone slope; a pressure-reducing cone equipped with a mixing chamber inside is arranged in the center of the top of the base; the bottom of the pressure-reducing cone is …

Grinding and homogenization. The grinding process takes place in a raw mill to reduce the particle size of the components to a typical value of 10-15 % residue on a 90 um sieve. The output of the grinding process – called 'raw meal' – is transferred to a homogenization silo before the clinker manufacturing process. Keeping the material ...
