1. PAINPOINT DRIVE NOLEING

Танай кокс шигших үйл ажиллагаа тасралтгүй үргэлжилж байна уу, зардал ихтэй үр ашиггүй байдал? For plant managers and engineering contractors in the metallurgical coke and foundry coke sectors, the vibration screen is a critical yet problematic node. Нийтлэг бэрхшээлүүд орно:

Нүд сохлох & Тээвэрлэлт: Moisture and fine coke dust adhere to screen decks, blinding apertures and forcing undersized material to carry over. This reduces screening efficiency by 1530%, contaminates product grades, and directly impacts blast furnace burden consistency.
Засвар үйлчилгээний хэт их зогсолт: Traditional screens require frequent shutdowns for deck cleaning, хурцадмал байдал, or panel replacement. Unplanned downtime for a primary coke screen can cost over $5,000 алдагдсан үйлдвэрлэлд цагт.
Бүтцийн ядаргаа & Premature Failure: The abrasive nature of coke and the highcycle operation induce metal fatigue in side plates, cross members, and welds. This leads to catastrophic frame cracks, often within 1218 үйлчилгээний сар, necessitating a full rebuild or replacement.
Эрчим хүчний өндөр хэрэглээ & Дуу чимээ: Inefficient drive systems and unbalanced mass designs consume excess power—a significant operational cost—while generating noise levels that exceed 90 дүүдэр(Аг), creating environmental and worker safety concerns.

Are you seeking a vibration screen solution that delivers consistent product sizing with minimal downtime, engineered specifically for the harsh demands of coke classification?

2. БҮТЭЭГДЭХҮҮНИЙ ТОЙМ

Хятадын коксын чичиргээт дэлгэц нь хүнд даацын зориулалттай, linear motion vibrating screen designed for the highcapacity sizing and scalping of metallurgical (тэсэлгээний зуух) coke and foundry coke. Engineered for robustness in highabrasion, highdutycycle environments, it ensures reliable separation of coke breeze from lump coke.

Үйл ажиллагааны ажлын урсгал:
1. Тэжээл & Хувиарилалт: Sized coke from the crusher or oven is fed onto the screen via a regulated feed chute onto a robust feed deck for even material distribution.
2. Давхаргалалт & Хуваах: The dualshaft vibrator assembly generates a linear throwing motion, давхаргажуулах материал. Хэт том (бөөн кокс) travels across the deck surface to the discharge end, дутуу байхад (коксын сэвшээ салхи) passes through the defined screen apertures.
3. Бүтээгдэхүүнтэй харьцах: Separated fractions are discharged via dedicated chutes—lump coke to blast furnace stockhouses or loading bays, and coke breeze to sintering plants or storage.

Хэрэглээний хамрах хүрээ: Анхан шатны хэмжээ (жишээ нь e., separating >25mm from <25мм), scalpings of oven charge, dedusting of crushed coke. Not recommended for extremely sticky materials without specialized deck systems or for wet screening applications without design modifications.
