sinter was poured from the pot into a single-toothed roller crusher for crushing and then dropped con-tinuously 4 times at a height of 2000 mm. After screening and classification, the part with a particle size greater than 5 mm was the finished sinter, and the part with a particle size less than 5 mm was the return fines.

Sintering is a manufacturing process used for making various parts from metal or ceramic powder mixtures. Sintering can be defined as the thermal transformation of bulk materials into compact solids at temperatures below their melting point [1–4].The main phenomenon is solid state diffusion, which occurs along the different interfaces of the crystals and through any vacancies.

The cone crusher consists mainly of a mantle and a concave, with the minimum distance between them defined as the closed side setting (CSS). The complex motion behaviors of particles in a cone crusher are influenced by operation parameters (e.g., CSS, eccentric angle and eccentric speed).

The sinter grate encounters various types of wear loading, especially abrasion, impact and high-temperature erosion. An optical image of a sinter grate and the temperatures attained in service are shown in Fig. 1. The sinter cake falls 4 m deep onto the sinter grate and the rotating sinter crusher pushes the sinter through the sinter grate.
