1. HAPJE NGA PIKA E DIKIMIT

Are you facing persistent bottlenecks in your cement production line that directly impact throughput and profitability? Për menaxherët e impianteve dhe kontraktorët inxhinierikë, the challenges associated with Mulliri me rul vertikal (VRM) operation are often quantifiable: unplanned downtime due to roller and table wear, inconsistent product fineness affecting kiln feed quality, and high specific energy consumption driving operational costs. These issues manifest as lost production hours, increased maintenance labor, dhe fuqi e humbur. How can you achieve stable, highvolume grinding of raw meal or cement with predictable wear life and lower kilowatthours per ton? Zgjidhja kërkon pajisje të krijuara jo vetëm për kapacitet, but for operational continuity and total cost of ownership.

2. PËRMBLEDHJE E PRODUKTIT

Jonë Mulliri me rul vertikal (VRM) is a core grinding system designed for the dry grinding of raw materials, klinker, granulated blast furnace slag, and pozzolana for cement manufacture. Rrjedha e punës së saj operacionale është e vazhdueshme, integrated process:
1. Prezantimi i ushqimit: Material is fed centrally onto the rotating grinding table.
2. Bluarje & Tharje: Centrifugal force moves material under hydraulically loaded rollers; simultaneous drying via hot gas intake from kiln exhaust.
3. Klasifikimi & Ndarja: Ground material is transported by gas stream to an integrated classifier; oversize particles are rejected back to the table.
4. Mbledhja e produkteve: Fine product exits with the gas to a baghouse or electrostatic precipitator for collection.
5. Reject Handling: Hard or ungrindable material (metal tramp) is discharged externally via the tailings gate.

Application scope includes primary and finish grinding in cement plants. Kufizimet kryesore përfshijnë madhësinë e furnizimit (zakonisht 75 mm) dhe përmbajtjen e lagështisë (optimized for drying with waste heat).
