摘要: Method to artificially agglomerate finely divided materials. A method to agglomerate finely divided material into aggregates, the aggregates being larger than the finely divided material, comprising the steps of (a) mixing finely divided material, binder and water in a mixer, (b) adding an agglomerating agent to the mix formed in step (a) and mixing constantly. Finely divided material is selected from the group consisting of cement, sand, clay, glass, slag, fly ash, stone powder, bypass dust, limestone, silica fume, crushed brick, brick powder and crushed stone or a combination thereof.

摘要: Method to produce aggregates from unsettled cementitious mixtures, comprising the steps of (a) adding at least one pelletizing agent to an unsettled cementitious mixture, (b) mixing constantly the mixture of step (a) in a mixer to produce pellets, (c) discharging the pellets obtained in step (b) and (d) drying the pellets formed in step (c). The pelletizing agent is selected from the group consisting of cellulose, chitosan, collagen, polyacrylamide and co-polymers of polyacrylamide and polyacrylics, polyamines, polyvinylalcohols, polysaccharides, lactic acid, methacrylic acid, methacrylate, hydroxyethyl, ethylene glycol, ethylene oxide, acrylic acid, inorganic flocculants and inorganic coagulants.
