Manufacture Process Of Coarse Aggregates

Process for the production of coarse, scrubbing

A process for the production of coarse scrubbing aggregates of TiO 2 particles by vapor phase oxidation of titanium tetrachloride. The particle aggregates of sizes above 0.15 mm are separated from the TiO 2 fines by wet screening on a moving screen, calcined and returned to the process. In a preferred embodiment of the process, the titanium dioxide prior to calcination is admixed with 0.01 to

Sieve Analysis of Coarse Aggregate: The Test

A sieve analysis or gradation test determines the distribution of aggregate particles by size within a given sample. This information can then be used to determine compliance with design and production requirements. Data can also be used to better understand the relationship between aggregates or blends and to predict trends during production.

ABSTRACT The invention concerns a process for the production of coarse scrubbing aggregates of TiO2 particles by vapour phase oxidation of titanium tetrachloride, the particle aggregates of sizes above 0.15 mm being separated from the TiO2 fines by the wet route on a moved screen, calcined and returned to the process. In a preferred embodiment of the process, the titanium dioxide prior to

after minimal processing. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed stone is produced by crushing quarry rock, boul-ders, cobbles, or large-size gravel. Crushed air-cooled blast-furnace slag is also used as fine or coarse aggregate. The aggregates are usually washed and graded at the pit or
