ڪوڪ وائبريشن اسڪرين سورسنگ ايجنٽ جي خريداري
1. PAINPOINT driven اوپننگ
ڇا توهان جي ڪوڪ هٿ ڪرڻ ۽ درجه بندي جو عمل دائمي گھٽتائي ۽ قيمت اووررن جو هڪ ذريعو آهي? ڪوڪ اسڪريننگ جي نگراني ڪندڙ پلانٽ مينيجرز لاءِ, عام آپريشنل چئلينج شامل آهن:
انڌو ڪرڻ & کڻندڙ: ٺيڪ, چپچپا ڪوڪ ذرات انڌا اسڪرين ڊيڪ, جڏهن ته وڏو مواد ختم ٿيل پراڊڪٽ بِن ۾ کڻي وڃي ٿو, سمجهوتو معيار ۽ دستي مداخلت کي مجبور ڪرڻ.
گھڻي سار سنڀال واري سائيڪل: ڪوڪ جي گھڻائي واري فطرت اسڪرين پينلز تي لباس کي تيز ڪري ٿي, بيئرنگ, ۽ exciters, بار بار جي اڳواڻي, حصن جي بدلي لاءِ اڻ رٿيل بندش.
غير موثر جزا جدا ڪرڻ: نامناسب وائبريشن جا نمونا نٽ ڪوڪ کان هوا کي صحيح طرح الڳ ڪرڻ ۾ ناڪام ٿين ٿا, نتيجي جي نتيجي ۾ پيداوار جي وضاحت گم ٿي وئي ۽ غلط ڪلاس ٿيل مواد مان آمدني وڃائي وئي.
ساخت جي ٿڪ & ناڪامي: ھائي سائيڪل آپريشن بھاري لوڊ ھيٺ ويلڊ ڪرڪس ۽ اسڪرين جي جسم ۾ ساخت جي ناڪامي جو سبب بڻجن ٿا, وڏي سرمائي جي مرمت جي واقعن کي ٺاهڻ.
These issues translate directly into quantifiable losses: hours of lost production per month, وڌندڙ اسپيئر پارٽس جي فهرست, and inconsistent product quality affecting customer contracts. How do you achieve reliable separation with minimal maintenance? The answer lies in specifying a purposeengineered ڪوڪ وائبريشن اسڪرين.
2. پيداوار جو جائزو
اي ڪوڪ وائبريشن اسڪرين هڪ Heavyduty صنعتي اسڪريننگ مشين scalping لاء ٺهيل آهي, ماپ ڪرڻ, ۽ ميٽالرجيڪل ڪوڪ ۽ پيٽروليم ڪوڪ کي ختم ڪرڻ. Its core function is to separate bulk coke into precise fractions (مثال, ڌماڪي جي فرنس نٽ ڪوڪ, foundry coke, هوا) using controlled vibratory motion.
آپريشنل ڪم فلو:
1. کاڌو & ورهائڻ: Bulk coke is fed onto the screen’s robust feed box, which evenly distributes material across the full width of the first screening deck.
2. Stratification & جدائي: Highintensity vibration stratifies the material; fines pass through upper deck apertures while larger particles travel across the deck surface.
3. ماپڻ & خارج ٿيڻ: Multideck configurations allow for sequential sizing. Correctly sized fractions discharge from designated discharge spouts into separate conveyors or bins for downstream processing.
ايپليڪيشن جو دائرو: Primary sizing of ovendischarged coke, scalpandscreen circuits in byproduct plants, final product grading before shipment, ۽ desusting اپليڪيشن.
حدون: گلي اسڪريننگ يا سلري ايپليڪيشنن لاءِ ٺهيل ناهي. Maximum lump size is constrained by feed chute and deck aperture design; typically handles feed sizes up to 300mm.

Integrated Steel Plant – Blast Furnace Feed Circuit
Challenge A major steel producer faced persistent blinding on their primary coke screens during humid months.This caused nut coke contamination with excessive fines (6ايم ايم), risking blast furnace permeability,and required biweekly manual cleaning halting the line.Their existing screens' welded decks were prone to cracking,causing further unplanned downtime.Solution Implementation of two new heavyduty Coke Vibration Screens featuring sealed balltray antiblinding systems,a bolted modular deck structure,and polyurethane panels.The installation was timed with a scheduled furnace reline.The Results Screening efficiency for 6mm material stabilized at ≥96%.Manual cleaning was eliminated.Product consistency improved,directly contributing to stable furnace operation.Maintenance downtime related to screening was reduced by an estimated75%,and no structural repairs have been required in three years of operation.
Petroleum Coke Processing Terminal
Challenge At a bulk export terminal handling calcined petroleum coke,vibrationinduced fatigue was causing catastrophic failures in screen support structures every1418 months.Dust emission at transfer points also exceeded new local regulations,due to poor sealing on old equipment.Solution Procurement of customengineered Coke Vibration Screens with reinforced,twinbeam base frames designed for higher Gforces,and fully enclosed,dusttight bodies integrated with the plant's extraction system.The Results Structural integrity has been maintained beyond36 months with no signs of stress fatigue.Dust emissions at the screening station measured below permitted levels,satisfying compliance audits.The terminal reported a22% reduction in total costofownership per ton screened over two years due to lower repair costs
