Pelletizing - Wikipedia

The process of pelletizing combines mixing of the raw material, forming the pellet and a thermal treatment baking the soft raw pellet to hard spheres. The raw material is rolled into a ball, then fired in a kiln or in travelling grate to sinter the particles into a hard sphere. The configuration of iron ore pellets as packed spheres in the blast furnace allows air to flow between the pellets ...

Understanding Pellets and Pellet Plant Operations –

21/03/2015  The grate-kiln system offers excellent temperature control in all stages of the process and produces a consistently uniform quality pellet. Fuel consumption is 75 M cal to 100 M cal per ton of standard pellets produced when using magnetite ore, and up to 170 M cal per ton of standard pellets produced when the feed is hematite. These fuel consumption numbers increase by 60 M cal per ton

Grate Kiln Process The grate-kiln process has three units for meeting radically different thermal conditions. Drying, pre-heating and oxidation are carried out in a traveling grate while pellets are fired in a rotary kiln by radiation. Hot pellets are cooled in a rotary cooler. Hot air from the rotary kiln is used in the grate

Cement kiln - Wikipedia

The pellets are loaded onto the moving grate, and the hot combustion gases from the rear of the kiln are passed through the bed of pellets from beneath. This dries and partially calcines the rawmix very efficiently. The pellets then drop into the kiln. Very little powdery material is blown out of the kiln. Because the rawmix is damped in order to make pellets, this is referred to as a "semi ...
