1. PYNPUNT GEDREWE OPENING

Are your coke screening operations plagued by persistent inefficiencies that directly impact your bottom line? Algemene uitdagings sluit in:

Oormatige stilstand: Frequent screen cloth blinding and premature wear from abrasive coke fines, leading to unscheduled maintenance stops and lost production hours.
Inkonsekwente produkgradering: Inefficient separation resulting in offspec material—oversize particles contaminating the nut coke fraction or excessive fines in the blast furnace feedstock—compromising downstream process efficiency.
Hoë bedryfskoste: Constant replacement of screen decks, excessive energy consumption from inefficient vibration mechanisms, and high labor costs for manual clearing and maintenance.
Kommer oor strukturele integriteit: Vibration transmission to support structures causing fatigue cracks and foundation issues, creating longterm plant safety and capital expenditure risks.
Stof Emissie & Vermorsing: Poor sealing and excessive vibration exacerbate housekeeping issues, creating environmental control challenges and product loss.

Is your current screening solution a source of recurring cost and reliability headaches? Wat sou 'n 2030% reduction in maintenance intervals and a 15% improvement in screening efficiency mean for your annual operational budget?

2. PRODUK OORSIG

The Coke Vibration Screen is a heavyduty, highcapacity screening machine engineered for the precise size classification of metallurgical coke. It separates crushed coke into defined fractions—such as blast furnace coke, neut coke, and breeze—critical for optimal furnace operation.

Operasionele werkvloei:
1. Voer Inleiding: Crushed coke is uniformly distributed onto the feed box of the inclined screen deck(s).
2. Vibrerende skeiding: A highefficiency vibrator assembly imparts a linear or elliptical motion, stratifying material and propelling it across the screening surface.
3. .SizeBased Stratification: Particles smaller than the screen aperture fall through as undersize, while larger particles travel across the deck to discharge as oversize.
4. Fraksie ontslag: Separated material streams are discharged via dedicated chutes into designated collection hoppers or conveyors for further processing or shipment.

Toepassingsomvang & Beperkings:
Omvang: Ideal for primary sizing of hot or cold metallurgical coke in coke plants, staalfabrieke, en grootmaat hantering terminale. Effective for capacities ranging from 200 aan 1500+ ton per uur.
Beperkings: Nie ontwerp vir taai materiaal sonder voorbehandeling nie (bv., preheating). Performance is contingent on proper feed rate control and consistent moisture content management.
