1. HAPJE NGA PIKA E DIKIMIT
Is your foundry or steel plant’s coke handling process a persistent bottleneck? The screening of metallurgical coke is critical, yet often plagued by inefficiencies that directly impact your bottom line. Sfidat e zakonshme operacionale përfshijnë:
Verbimi & Transporti: Fine particles and moisture cause screen mesh blinding, reduktimin e zonës efektive të shqyrtimit. Njëkohësisht, oversized material carries over into the product stream, contaminating blast furnace feed and compromising furnace efficiency.
Koha e tepruar joproduktive & Mirëmbajtja: Traditional screens with complex drive mechanisms and numerous bearings require frequent lubrication and are prone to mechanical failure, leading to unplanned shutdowns and high spare parts inventories.
Efikasitet i ulët i shqyrtimit & Kapaciteti: Inadequate vibration dynamics result in poor material stratification and rapid travel speed, causing fines to bypass the screening process. This forces recirculation of material, wasting energy and limiting overall plant throughput.
Lodhja strukturore & Zhurma: Highstress, unbalanced forces from conventional exciters transmit damaging vibrations to the support structure and generate excessive noise levels, raising safety concerns and increasing longterm facility maintenance costs.
Are you seeking a screening solution that delivers consistent product grade, maksimizon kohën e funksionimit, and provides a measurable return on investment through reduced operational expense?
2. PËRMBLEDHJE E PRODUKTIT
The Professional Coke Vibration Screen is a highcapacity, linear motion vibrating screen engineered specifically for the rigorous dry screening of metallurgical coke in sizing (p.sh., 2580mm) and scalping applications. Its design focuses on reliability, saktësi, and low total cost of ownership in heavyduty industrial environments.
Rrjedha e punës operative:
1. Feed & Shpërndarja: Coke feedstock is evenly distributed across the full width of the screen via an integrated feed box or chute.
2. Stratifikimi & Ndarja: A controlled linear vibratory motion stratifies the material bed, allowing fines to contact the screen media while conveying larger particles along the deck length.
3. Size Segregation: Properly sized coke passes through the screen apertures as product, ndërsa materiali me përmasa të mëdha shkarkohet në fund të kuvertës.
Fusha e Aplikimit: Madhësia kryesore e koksit të furrës së shpërthimit (BF Coke), ndarja e erës së koksit, scalping of coke oven feedstock. Ideal for postcrusher screening in coke processing plants.
Kufizimet: Not designed for wet screening applications or for materials with extreme adhesive properties without specific deck modifications.
