Increasing environmental standards requirements encourage cement manufacturers to drastically decarbonize their process. In this context, the growing use of alternative fuelss is cost-effective and sustainable. The key point is to keep the optimal performance of the kiln. Indeed, the injection of alternative fuels causes more complex combustions in the furnace. It also causes the emission of harmful and dangerous fumes for its operation. To contribute to kiln preservation, HASLER Group offers a solution to process furnace dust by integrating its loss in weigh feeder within the installed chlorine bypass systems. Thus the risks of fouling and corking of the kiln are avoided and the recovered dust which presents the risk of vaulting is nevertheless precisely dosed for the cement crusher.
RBP : loss in weigh feeder since 1977
Advantages :
● High temperature 150/200°C,
● Accuracy: ± 0,5 %
● Flow range from 12 l/h to 14 m3/h
● Accuracy consistency
● Entirely tight system : no environmental impact
● Low maintenance
● No need for drop tests
● Few wear parts
● Manual or automatic refill
Options :
Horizontal agitator in the lower part to guarantee the homogeneity of the material. (Optional: vertical agitator for products with poor flowability)
Bearing at the screw outlet for better centering in the tube (reduction of the overhang).
