1. PYNPUNT GEDREWE OPENING

Is your coke handling operation losing profitability to inefficient screening? Common challenges with conventional screens directly impact your bottom line. Ervaar jy:
Excessive Product Loss: Fines and valuable coke breeze passing through worn or inefficient screen decks, wat direkte inkomsteverlies verteenwoordig met elke ton verwerk.
Hoë instandhoudingstyd: Frequent failures of screen decks, laers, or exciters due to the extreme abrasion and impact of coke, leading to unscheduled stoppages and production delays.
Verblinding & Poor Efficiency: Moisture or sticky fines blinding screen meshes, drastically reducing effective screening area and throughput, forcing recirculation and increasing energy costs.
Inkonsekwente produkgradering: Unreliable particle size separation resulting in offspec product for blast furnace or foundry customers, risking contract penalties and reputational damage.
Kommer oor strukturele integriteit: Konstant, highimpact vibration leading to fatigue cracks in the screen body or support structure, creating major safety risks and costly capital repairs.

Die kernvraag vir aanlegbestuurders is: hoe kan jy presies bereik, reliable coke classification while maximizing uptime and protecting your material yield?

2. PRODUK OORSIG

The Export Coke Vibration Screen is a heavyduty, highcapacity screening machine engineered for the dry classification of metallurgical coke and coke breeze. Designed for robustness in harsh environments, it separates crushed coke into precise size fractions critical for blast furnace efficiency and other industrial processes.

Operasionele werkvloei:
1. Voer Inleiding: Sized coke from crushers is evenly distributed onto the feed box of the vibrating screen.
2. Stratifikasie & Skeiding: Hoë intensiteit, linear or circular vibration stratifies the material bed. Smaller particles descend to contact the screen cloth apertures, terwyl groter deeltjies oor die dekoppervlak beweeg.
3. Grootte Fraksie Ontlading: Correctly sized particles pass through the screen mesh (ondermaat), while oversized particles discharge at the deck end (oormaat). Multideck configurations allow for simultaneous separation into several product grades.

Toepassingsomvang: Primêre en sekondêre sifting van metallurgiese kooks, coke bries herstel, sizing for sinter plants, and prescreening for gasification processes.

Beperkings: Nie ontwerp vir nat siftingstoepassings of vir materiale met uiterste kleef-eienskappe sonder gespesialiseerde dekbehandelings nie.

6. TOEPASSINGSSCENARIO'S

Integrated Steel Plant Blast Furnace Feed

Challenge A major steel producer faced consistent fines (5mm) contamination in their BFgrade coke (2575mm), affecting furnace permeability and increasing coke rate.
Solution Installation of a primary Export Coke Vibration Screen with two decks following secondary crushing.
Results Achieved a clean +25mm product with less than 3% undersize contamination while recovering 5mm breeze for sinter plant use—a quantifiable reduction of $12/ton in effective BF feed cost.

Handelaar Coke Vervaardiger

Challenge Offspec product batches due to inconsistent screening after rain events caused moistureinduced blinding on traditional screens.
Solution Implementation of our screens equipped with specialized antiblinding polyurethane decks featuring slotted apertures and balltray cleaning systems.
