Are your current screening solutions designed to handle the specific moisture, ڇڪڻ, and particle shape characteristics of imported petroleum coke? The following analysis provides the technical criteria for sourcing a vibration screen that addresses these specific failure modes.
2. پيداوار جو جائزو
جي import coke vibration screen هڪ سخت فرض آهي, linearmotion or circularmotion screening machine engineered specifically for the classification, ختم ڪرڻ, and dewatering of petroleum coke (سائو, calcined, or anodegrade). It is designed to operate in the hightemperature, highdust environments typical of coke calcining and anode production plants.
آپريشنل ڪم فلو (5 اهم قدم):
1. Feed Inlet: Material enters via a flared chute designed to minimize impact velocity and reduce particle degradation.
2. ورهائڻ: A builtin feed box or distributor plate spreads the coke across the full width of the screen deck (typically 1.5m to 3.0m).
3. Stratification: Linear vibration (68mm amplitude, 7501000 آر پي ايم) causes fine particles to migrate to the bottom of the material bed.
4. جدائي: Material passes over 13 deck layers (typically polyurethane or modular rubber panels with apertures from 3mm to 50mm). Oversize material travels to the discharge end; undersize passes through.
5. خارج ٿيڻ: Separate chutes direct oversize, پيداوار, and fines fractions to downstream conveyors or storage.

8. FAQ
Q1: Can this import coke vibration screen handle calcined coke at 200°C?
ها. The standard configuration is rated for material temperatures up to 120°C. For calcined coke (200300°C), we specify hightemperature polyurethane (rated to 180°C) or stainless steel wire mesh with expansion gaps. The exciter bearings must be upgraded to hightemperature grease (NLGI 2, operating range 20°C to +180°C).
Q2: What is the typical lead time for sourcing this equipment?
Standard configurations (اڪيلو ڇت, 150200 ٽي پي ايڇ) have a lead time of 1214 آرڊر جي تصديق کان هفتي. Custom configurations (double/triple deck, heated systems) require 1620 هفتا. Expedited production (810 هفتا) is available at a 15% پريميئم.
Q3: How does the modular polyurethane deck compare to rubber panels for coke screening?
Polyurethane offers 3040% longer wear life than rubber in coke applications due to superior abrasion resistance. بهرحال, rubber panels provide better selfcleaning in sticky, highmoisture conditions. For green coke with moisture >12%, we recommend rubber; for calcined or dry coke, polyurethane is the optimal choice.
Q4: What is the expected power consumption per ton of material processed?
At full load (300 ٽي پي ايڇ), the CVS2400 consumes approximately 30 ڪلواٽ (2 x 15 kW موٽر). This equates to 0.10 kWh في ٽون. Including dust collection and auxiliary systems, total energy cost is approximately $0.008 per ton at $0.08/kWh.
Q5: Can this screen be retrofitted into an existing structure without foundation modifications?
ها. The aircushioned isolation system transmits less than 8% of dynamic load to the support structure. We provide structural load calculations for your specific platform. اڪثر ڪيسن ۾, existing steelwork rated for 5 kPa live load is sufficient without reinforcement.
Q6: What warranty terms are standard for import coke vibration screens?
Standard warranty is 24 months from commissioning or 30 months from shipment, جيڪو پهرين ٿئي ٿو. This covers manufacturing defects in structural components, exciter units, ۽ موٽر. Screen media (polyurethane پينل) carry a separate 12month warranty against premature wear (defined as less than 2,000 ڪم جا ڪلاڪ).
Q7: How do I verify the screening efficiency before purchase?
We offer a pilotscale test (12 ٽي پي ايڇ) using your actual coke sample at our testing facility. Results include particle size distribution analysis, efficiency curves, and wear rate projections. This service costs $3,500, which is credited toward your first equipment order. متبادل طور تي, we can arrange a site visit to your facility for a 48hour trial using a rental unit.
