Single-toothed roll crushers are typically installed at the discharge end of sintering machines to break high-temperature sinter cakes into particle sizes suitable for cooling and transport. Subjected to continuous impact, compression, and high-temperature abrasion from the hot sinter, components such as the toothed roll, grate plates, liners, and inner casing walls are highly susceptible to wear and deformation.
Utilizing high-strength cast steel, heat- and wear-resistant materials, and hard-facing techniques can reinforce tooth surfaces and critical areas of the crushing chamber; this helps maintain the crushing geometry, reduce energy consumption, and ensure consistent crushing efficiency. Given their operation in high-temperature, highly abrasive environments, such reinforcement extends the service life of single-roll sinter crushers and minimizes downtime.
