Importance. A Coriolis meter is based on the principles of motion mechanics. When the process fluid enters the sensor, it is split. During operation, a drive coil stimulates the tubes to oscillate in opposition at the natural resonant frequency. As the tubes oscillate, the voltage generated from each pickoff creates a .

The most widely used industrial processes for pellet induration are the straight grate and the gratekiln. The straight grate process is composed of a single furnace where an endless line of pallet cars moves. A layer of indurated pellets is arranged at the bottom of each car to protect it against the heat.

Basically a straight grate induration furnace consists of three different zones, a drying zone, a firing zone and a cooling zone, and their purpose is to upgrade crude iron ore to the final product of iron ore pellet. As an initial step of the project, the mass and energy flows within a straight grate induration furnace have been analysed.

This high grade iron ore concentrates in form of slurry is transported to pellet plant through underground slurry pipeline. After receiving this slurry at pellet plant, the slurry is filtered and filtered cake is being used to produce iron ore pellets through indurating furnace of travelling grate technology.

Jun 09, 2019· The pellets are baked hard in a preheating grate by means of hot gases from the kiln. The pellets then enter the kiln where temperature is about 1450°C. The dry material undergoes a series of chemical reactions in the hottest part of the kiln and some 20 to 30 percent of the material becomes liquid, and lime, silica and alumina recombine.
