An impact crusher is a piece of heavy construction equipment people can use to reduce the size of things like rock, waste concrete, and similar materials.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
The ball mill is one of the most widely used super fine grinding machine in the industry and it is the key grinding equipment after materials have been crushed.
Fig. 6-2 shows the flow diagram of mixingof raw materialsby the wet process. It is thus seen that in case of mixingof raw materialsby dry process, therawmix is formed and in case of mixingof raw materialsby wet process, the slurry is formed. The remaining two operations namely, burning andgrinding, are the same for both the processes. 2.Read More
The manufacture of Portlandcementis a complex process and done in the following steps:grindingtheraw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, thesematerialspartially fuse to form nodular shaped clinker by broking of chemical bonds of ...Read More
Cement, in general, adhesive substances of all kinds, but, in a narrower sense, the bindingmaterialsused in building and civil engineering construction. Cements of this kind are finely ground powders that, when mixed with water, set to a hard mass.Setting and hardening result from hydration, which is a chemical combination of thecementcompounds with water that yields submicroscopic ...Read More
Cementcan be defined as the bondingmaterialhaving cohesive & adhesive properties which makes it capable to unite the different constructionmaterialsand form the compacted assembly. Ordinary/Normal Portlandcementis one of the most widely used type of PortlandCement. The name Portlandcementwas given by Joseph Aspdin in 1824 due to its similarity inRead More
