1. HAPJE NGA PIKA E DIKIMIT
Is your mineral processing operation constrained by inconsistent grind size, konsumimi i tepërt i astarit, or unplanned maintenance halting production? These common challenges directly impact your plant’s throughput and profitability. Consider the costs: unscheduled downtime for liner replacement can cost thousands per hour in lost production, while inefficient grinding consumes excess power and fails to liberate valuable minerals, reducing recovery rates. Are you managing high energy consumption per ton of processed material? Are your maintenance teams spending more time on reactive repairs than on planned optimization? The reliability and efficiency of your comminution circuit hinge on the core equipment at its heart. Addressing these issues requires a mill engineered not just for capacity, por për të qëndrueshme, operim me kosto efektive.
2. PËRMBLEDHJE E PRODUKTIT
This product is a robust, heavyduty ball mill designed for the continuous grinding of ores and minerals in both greenfield and brownfield processing plants. It operates on the principle of impact and attrition, where grinding media (steel balls) cascade within a rotating cylindrical shell to reduce feed material to a fine slurry or powder.
Rrjedha e punës operative:
1. Prezantimi i ushqimit: Crushed ore (<25mm) is conveyed, often with water, into the mill via a trunnion or peripheral feed chute.
2. Grinding Action: The rotating drum lifts the charge of steel balls; as they cascade, they fracture ore particles through impact and shear forces.
3. Reduktimi i madhësisë së grimcave: Material is ground progressively as it travels from the feed to the discharge end.
4. Shkarkimi i llumit: The ground product exits as a slurry through discharge grates, which retain grinding media while allowing sized material to pass for further processing.
Fusha e Aplikimit: Ideal for wet or dry grinding in secondary and regrind applications across base metals (bakri, plumbi, zinku), precious metals (ari), minerale industriale, and cement clinker.
Kufizimet: Not suitable for primary crushing of runofmine ore. Optimal performance requires correctly sized feed from upstream crushing circuits. Highly abrasive ores will accelerate wear rates, necessitating appropriate material selection.
