Unlike anunheated coating process, here, arotary kilnheats the coating material to just below liquefaction point, allowing it to coat the heat resistant core more evenly and more securely. Thisprocessis commonly seen in the manufacture ofroofinggranules, where a mineral such as granite is coated with a colored pigment, producing a product that is both durable and aesthetically pleasing.

Flow chart of the Tunnel Kiln process is as under; Tunnel Kiln history dates back to 1807 when Hoganas first used this process to produce iron powder of 99.9% purity. When iron ore is mined or processed (in a crusher), lots of fines are generated. Quantity of fines generation is a function of the quality of ore i.e. whether it is hard or soft.
