The sintering process is a thermal agglomeration process, and it is accompanied by chemical reactions. In this process, a mixture of iron ore fines, flux, and coal particles is heated to about 1300 °C–1480 °C in a sinter bed. The strength and reducibility properties of iron ore sinter are obtained by liquid phase sintering.

The (Snyder Type) Ore Sampler is available in both simplex and tandem units. The simplex unit is for final sample cuts of 5%, 10%, or 15% of the material fed to the sampler; and the tandem unit is for final sample cuts as small as 1%, or one-fourth of 1%, of the amount of material fed to the sampler. All samplers include feed hopper and chute ...
