1. PAINPOINT driven اوپننگ
Are you facing persistent bottlenecks in your cement production line that directly impact throughput and profitability? پلانٽ مينيجرز ۽ انجنيئرنگ ٺيڪيدارن لاءِ, the challenges associated with عمودي رولر مل (وي آر ايم) 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, ۽ طاقت ضايع ڪرڻ. How can you achieve stable, highvolume grinding of raw meal or cement with predictable wear life and lower kilowatthours per ton? حل جي ضرورت آهي سامان انجنيئر ٿيل نه رڳو گنجائش لاءِ, but for operational continuity and total cost of ownership.
2. پيداوار جو جائزو
اسان جي عمودي رولر مل (وي آر ايم) is a core grinding system designed for the dry grinding of raw materials, ڪلينر, granulated blast furnace slag, and pozzolana for cement manufacture. Its operational workflow is a continuous, integrated process:
1. فيڊ جو تعارف: Material is fed centrally onto the rotating grinding table.
2. ڏاڪڻ & خشڪ ڪرڻ: Centrifugal force moves material under hydraulically loaded rollers; simultaneous drying via hot gas intake from kiln exhaust.
3. درجه بندي & جدائي: Ground material is transported by gas stream to an integrated classifier; oversize particles are rejected back to the table.
4. پيداوار جو مجموعو: Fine product exits with the gas to a baghouse or electrostatic precipitator for collection.
5. Reject Handling: Hard or ungrindable material (ڌاتو ڌاتو) is discharged externally via the tailings gate.
Application scope includes primary and finish grinding in cement plants. اهم حدون شامل آهن فيڊ سائيز (عام طور تي 75mm) ۽ نمي جو مواد (optimized for drying with waste heat).
