1. ABERTURA ACIONADA POR PAINPOINT

Você está gerenciando gargalos persistentes em sua linha de produção de cimento que impactam diretamente o rendimento e a lucratividade?? Para gerentes de fábrica e empreiteiros de engenharia, the reliability and efficiency of core processing equipment are nonnegotiable. Common challenges with rotary kiln systems include:
Tempo de inatividade não planejado: Catastrophic shell failures or refractory lining collapses can halt production for weeks, custando mais de $50,000 per day in lost output.
Qualidade de produto inconsistente: Irregular temperature profiles and material retention times lead to variable clinker quality, resulting in offspec product and customer rejections.
Consumo excessivo de energia: Inefficient combustion, má recuperação de calor, and excessive shell heat loss can increase specific thermal energy consumption by 1015%, a major operational cost.
Alta carga de manutenção: 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? O que seria um 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. VISÃO GERAL DO PRODUTO

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.

Fluxo de Trabalho Operacional:
1. Pré-aquecimento & Alimentação: Prepared raw meal enters the kiln’s upper end from the preheater tower.
2. Calcinação & Clinquerização: As the kiln rotates, material travels down the inclined cylinder through progressively hotter zones (decomposition, sintering, cooling) fueled by a precisely controlled burner at the discharge end.
3. Descarga & Resfriamento: The resulting clinker nodules exit into a dedicated cooler for rapid quenching to stabilize optimal mineral phases.

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