1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Bạn có đang quản lý các tắc nghẽn dai dẳng trong dây chuyền sản xuất xi măng ảnh hưởng trực tiếp đến sản lượng và lợi nhuận không?? Dành cho người quản lý nhà máy và nhà thầu kỹ thuật, the reliability and efficiency of core processing equipment are nonnegotiable. Common challenges with rotary kiln systems include:
Thời gian ngừng hoạt động ngoài kế hoạch: Catastrophic shell failures or refractory lining collapses can halt production for weeks, có giá lên tới $50,000 per day in lost output.
Chất lượng sản phẩm không nhất quán: Irregular temperature profiles and material retention times lead to variable clinker quality, resulting in offspec product and customer rejections.
Tiêu thụ năng lượng quá mức: Inefficient combustion, thu hồi nhiệt kém, and excessive shell heat loss can increase specific thermal energy consumption by 1015%, a major operational cost.
Gánh nặng bảo trì cao: Frequent mechanical alignment issues, roller station wear, and drive system failures demand constant attention from your maintenance crew.

Is your current kiln system a source of recurring cost and risk? Điều gì sẽ 5% increase in thermal efficiency mean for your annual operating budget? The solution lies in specifying OEM equipment engineered from the ground up to address these exact operational realities.

2. TỔNG QUAN SẢN PHẨM

The rotary kiln is the thermal heart of the cement plant, responsible for the calcination and clinkerization processes. Our OEM rotary kilns are engineered for continuous, hightonnage production of Portland cement clinker.

Quy trình hoạt động:
1. Làm nóng sơ bộ & cho ăn: Prepared raw meal enters the kiln’s upper end from the preheater tower.
2. nung & Clinker hóa: Khi lò quay, material travels down the inclined cylinder through progressively hotter zones (decomposition, sintering, cooling) fueled by a precisely controlled burner at the discharge end.
3. Phóng điện & làm mát: The resulting clinker nodules exit into a dedicated cooler for rapid quenching to stabilize optimal mineral phases.

Phạm vi ứng dụng: Primary application is for the production of cement clinker from limestonebased raw materials. Also suitable for processing other calcareous materials in allied industries.
Hạn chế: Not designed for alternative fuel feeding systems without specified modifications; maximum capacity is defined by shell diameter and drive power specifications.
