ROCESSING


Innovative coating prevents corrosion of steel hoppers and other mining equipment exposed to moisture, salt and abrasion

n mines, quarries and aggregate bulk processing, large steel structures, such as hoppers that are used to store and dispense vast volumes of ore, rock and


gravel, are often subjected to abrasion, moisture and salt deposits, which can accelerate corrosion. Once corrosion starts, often through a


breach in traditional barrier-type coatings such as epoxies, the coating can act like a greenhouse, trapping water, oxygen and other corrosion promoters. Tis allows the corrosion to spread quickly under the coating itself, which is difficult to inspect and can lead to failure and costly premature replacement. For these reasons, such coatings are typically reapplied at a sizeable cost in downtime, surface preparation and coating application. Fortunately, there is a new type of coating that offers extended corrosion
