Rotary kiln clinker

Nov 09, 2021

The clinker rotary kiln feeds the clinker powder directly into the kiln for calcination. The moisture rate of the clinker is generally 1% to 2%, sparking a large amount of heat by drying required for clinker. The main drive motor in the clinker rotary kiln transmits power to the open gear device through the main reducer

    May 24, 2019 Clinker kiln (cement kiln or cement rotary kiln) is the main equipment of cement plant. The clinker is formed by calcination in it. During the calcination process, raw meal powder is fed into the kiln cylinder from the top of the kiln tail. Due to the inclination and gentle rotation of the kiln cylinder, materials produce a compound movement

    Rotary kilns are cylindrical furnaces constructed of a steel shell and a refractory lining that rotates along the long axis. The axis of rotation is tilted so that gravity continuously moves a product like limestone from the high end, down the furnace toward a burner at the low end where the product is discharged into the clinker cooler
