Cement Kiln Dust Pneumatic Conveying System

Cement Kiln Dust Pneumatic Conveying System

Holcim Cantagalo recently came to Macawber Engineering’s Brazilian licensee, PDL Sistemas for a quality Cement Kiln Dust pneumatic conveying system for an intermediate system conveying to a final storage silo. This is to replace a pressurized silo truck which led to dusty conditions and inefficient plant operations. The systems have been installed and continue to operate reliably for the customer.
