Asphalt plants undergo severe wear due to the mixing of highly abrasive aggregate at high temperatures. Our experience with extremely abrasive commodities (concrete, coal, mineral mining and refining, recycling) and elevated temperatures (steel foundries, coal power plants), makes Abraservice uniquely qualified to help extend the life of your asphalt plant wear parts.
Abraservice manufactures asphalt plant wear parts that have been re-engineered for significantly longer service life. We do this by leveraging our proprietary range of abrasion-resistant (AR), corrosion-resistant (CR), high-temperature, or CCO overlay wear plates. Our engineers help you choose the most appropriate wear plate for each application, so you aren’t paying for unnecessary properties — only what you need for greatly improved uptime.
Some areas of asphalt plants see temperatures over 400°C, but traditional quenched and tempered (Q&T) wear-resistant steels experience a loss of hardness above 300°C.
By using high-quality raw materials processed in a carefully controlled milling process, Hardox® HiTemp is especially made for abrasive service in the 300°C to 500°C temperature range. A quenched and tempered martensitic wear plate with a typical hardness of 375 Brinell, Hardox® HiTemp also has a very high resistance to cracking and buckling. With Hardox® HiTemp, your asphalt plant’s wear parts stay in their proper shapes for a service life that’s significantly longer than traditional wear plate steels.
We replaced custom steel with a 235 HB with Hardox® 450 wear plate for a dryer drum and it’s removable aggregate mixing fins; all before and after parts are 6 mm thick.
