Rotary Piston Blower

Function

Technical Data

The amount of air required for pneumatic conveying of the material from through-blow rotary feeder to kiln is generated by a rotary piston blower with integrated pulsation reducer.

The constructional conception of this kind of blower ascertains high mechanical and volumetric efficiency at ultimate reliability and operating safety.

The rotary piston blower is dimensioned and integrated into the system in accordance with the project. The blower is mounted in a noise insulating housing.

Blower with 3-wing-type piston Sound reduction through pulsation degradation by means of two pre-intake channels cast into the pressure side of the cylinder Housing of GG20, ribbed and air-cooled Shafts and pistons (C45N) forged of a single piece Control gears of 16 Mn Cr5E Overhung drive via V-belts

Pneumatic Conveyor Line

Function

Technical Data

The conveyor line transports the fuel blown out of the rotary feeder chambers directly to the burner.

Air quantity, run length and pipe diameter are selected in accordance with the particular project so optimal material transport without line deposits is obtained at minimal abrasion of the pipe inner wall.

The line must be arranged horizontally and/or vertically. Pipe bends have to be reduced to the absolute minimum. Pipe lengths below 100 m enable the highest economic efficiency of the system.

To protect the system from kiln faults, an explosion check valve has been installed.
