Krome quarry improves product quality and delivery for customers
Listening to customers is an important part
of ensuring product quality. Through listening
and further research, a team at
Rinker Materials’ Krome quarry, west of
Miami in Kendall, Florida, found that an
automated blending system and a radial
stacker would improve the quality of materials
for customers.
Customer feedback showed that the gradation of one of Krome’s products could be changed to improve handling of mixes. Further investigation also revealed that the practice of loading directly from the face of the aggregate storage piles created increased variability, which could be improved.
The team at Krome reviewed crusher settings and screen changes to design a new blending system – a combination of two of Krome’s major products – to better service customer needs.
Once ready for shipment, materials are distributed from Krome by rail and truck. However, the new blending system only produced material for rail. An articulating stacker was also needed to prepare product transported by road.

Since installing the blending system, Krome quarry has seen a significant decrease in overall variability and the new blended product is a success with customers. The articulating radial stacker has also created a dramatic improvement from the old method of loading trucks from the live production piles.
Special mention for designing this system goes to plant manager Haim Pillosof, director of technical services Jim Cox, project automation engineer Terry Long, electrical engineer Eddy Yi, South Florida QC manager Ryan Stack and regional operations manager Johnny Arellano.
