1. PYNPUNT GEDREWE OPENING

Are you managing persistent bottlenecks in your cement production line that directly impact throughput and profitability? Vir aanlegbestuurders en ingenieurskontrakteurs, the reliability and efficiency of core processing equipment are nonnegotiable. Common challenges with rotary kiln systems include:
Onbeplande stilstand: Catastrophic shell failures or refractory lining collapses can halt production for weeks, kos opwaarts van $50,000 per day in lost output.
Inkonsekwente produkkwaliteit: Irregular temperature profiles and material retention times lead to variable clinker quality, resulting in offspec product and customer rejections.
Oormatige energieverbruik: Inefficient combustion, poor heat recovery, and excessive shell heat loss can increase specific thermal energy consumption by 1015%, a major operational cost.
Hoë Onderhoudslas: 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? Wat sou 'n 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. PRODUK OORSIG

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.

Operasionele werkvloei:
1. Voorverhitting & Voeding: Prepared raw meal enters the kiln’s upper end from the preheater tower.
2. Kalsinasie & Clinkerization: Soos die oond draai, material travels down the inclined cylinder through progressively hotter zones (decomposition, sintering, cooling) fueled by a precisely controlled burner at the discharge end.
3. Ontslag & Verkoeling: The resulting clinker nodules exit into a dedicated cooler for rapid quenching to stabilize optimal mineral phases.

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