Silverline Vertical Agitators - Cement, Ceramic, Sludge Mixer

When operating in a mine, concrete or ceramic area, processing plant or servicing, PRO-DO-MIX can help out in all processes that require preparation and storage of heavy slurry, ceramic slip (“barbottina”), cement grout, ceramic glaze, etc.

PRO-DO-MIX can supply heavy duty equipment for Ceramic as well as Mining and Concrete industry by utilizing industry leading processes and mechanical design technology.

In the Ceramic field we have worked with both plant engineering and end-users to replace existing old-designed “gate” mixers with innovative vertical agitators that combine treatment performances with superior energy efficiency thanks to our high-efficiency impellers.

Also, our engineering team is able to provide competent and expert technical assistance in designing tanks with correct dimension for optimal mixing.

Mixing is essential at different stages when dealing with ceramic or cement slurries, to keep the medium well homogenized in order to prevent product sedimentation.

PRO-DO-MIX have engineered different mixing technologies according to the specific applications and products to be handled:

Ceramic Slurry, the so called “barbottina”, is a viscous compound of water, clay and sometimes kaolin, used in the industrial production of ceramics. Specific gravity and viscosity are quite high and can vary according to the percentage of products dosed in the compound.

Ceramic Glaze is a layer or coating of a vitreous substance which is then fused to a ceramic body through firing. It can serve to colour, decorate or waterproof a ceramic item. It generally includes silica, which is the main glass former; metal oxides, such as sodium, potassium and calcium; alumina; colorants, such as iron oxide, copper carbonate or cobalt carbonate, or opacifiers, such as tin oxide or zirconium oxide.

Grout, or Cement Slurry, is a mixture of water and cement with possible presence of sand and/or drilling mud; it may consist of sludge from soil washing (tank/cement mixer washing) or homogenization in sludge storage / sludge suspension tank.
