IVITAS BEATER WHEEL MILLS

Mr. Dostal, why have you focused on the de- velopment of beater wheel mills? Our goal has been to design a complex system of technology for an efficient combustion process in a pulverized coal boiler in order to be ready for emis- sion reductions in heating and power plants accord- ing to regulations. In 2009, we started.

FL - ATOX® Coal Mill

How it works. The raw coal enters the mill via a feed screw and is discharged onto the rotating grinding table. The rotation of the table accelerates the flow of material towards the grinding track, where the coal is ground between the table and the three rollers. The coal then continues over the dam ring and is entrained in the.
