Most sugar factories operate around the clock during harvest season. The conveying line carries wet bagasse, cane trash and syrup splashes all the time. Ordinary carbon steel sprockets without proper heat treatment will suffer tooth abrasion and surface corrosion quickly.
C1045 steel is widely adopted for sugar conveyor sprockets for its balanced cost and mechanical performance. The key process is tooth induction hardening. We only harden the tooth surface instead of the whole sprocket body. This keeps the core tough to resist impact, while the tooth surface gains high hardness for anti-wear.
Many buyers tend to ignore the matching precision between sprocket and chain. Even a high-quality sprocket will wear rapidly if the pitch, tooth profile do not fit the sugar conveyor chain. For old sugar mill renovation projects, we always suggest customers check the existing chain pitch first, rather than only replacing the sprocket separately.
Surface treatment can be adjusted according to working conditions. Galvanizing suits areas with more moisture and syrup splash, while painting is a cost-effective choice for dry bagasse conveying sections.
