Abstract: The configuration of MQG-3660 primary ball mill with improved φ660 flat-bottom hydrocyclones makes the ball mill throughput to reach 240 t/h and its utilization coefficient to be 4.4 t/(m3·h).This kind of hydrocyclone is suitable for coarse particle classification and has high classification efficiency and an unblocked spigot, therefore being worthy of spreading.

Key words: Primary grinding and classification, Flat-bottom hydrocyclone, Classification efficiency
