Kiln Low NOx calciner

Reduction zone At high temperature

Kiln DeSOx system

Dry scrubber for sulfur Fix sulfur in the raw mix avoiding emissions

Kiln Tangential suspension

Free radial expansion of the shell to minimize ovality and maximize refractory life

Bracket are bolted onto the tyre “Dog bone” keep the tyre in position Welded blocks rest on elastic brackets bolted to sides of tire with spring-loaded

wedges in between Spring keeps wedge on position as dimension change with heat expansion

Kiln Friction drive

No lubrication needed usage Roller-tire friction Maintenance free

Clinker cooler• Cools clinker from 2600 F to 150 F

•Mechanical flow regulator system for air control

• Hydraulic drive

•Hydraulic roller breaker

Clinker cooler Mechanical Flow Regulator

( MFR ) system in the cooler Automatic control of cooling air Energy savings Transport separate from cooling

Clinker cooler Hydraulic Roller braker (HRB):
