1. PEMBUKAAN PAINPOINT DRIVEN

Managing the final stage of clinker cooling presents persistent operational challenges that directly impact plant profitability. Inefficient cooling leads to hightemperature clinker entering the conveyor system, accelerating belt wear and creating safety hazards for personnel. Excessive fan power consumption drives up operational costs, while inconsistent quenching results in poor cement quality and potential mill inefficiencies. Unplanned maintenance due to refractory damage or mechanical failure in the cooler causes costly kiln downtime.

Adakah anda menghadapi peningkatan kos tenaga bagi setiap tan klinker? Is your maintenance team constantly addressing downstream equipment damage from hot clinker? Are you achieving optimal cement quality and mill performance from your cooled clinker? A highperformance penyejuk parut is engineered to address these exact issues.

2. GAMBARAN KESELURUHAN PRODUK

The penyejuk parut salingan is a critical heat recovery and quenching machine installed at the kiln discharge. Its primary function is to rapidly reduce clinker temperature from approximately 1200°C to below 100°C for safe handling and grinding, while recovering thermal energy for process optimization.

Aliran Kerja Operasi:
1. Pengedaran: Hot clinker from the kiln is evenly distributed across the full width of the stationary inlet grate.
2. Pengangkutan & Pelindapkejutan: Reciprocating grates move the clinker bed toward the discharge end while controlled volumes of ambient air are forced upward through the bed.
3. Pemulihan Haba: Hightemperature exhaust air (lebih kurang. 300400°C) is directed to the kiln or precalciner as secondary/tertiary air.
4. Menyejukkan & Pelepasan: Further cooling with ambient air occurs in subsequent compartments before clinker is discharged at a stable, low temperature.
5. Pengendalian Habuk: Fines are collected via drag chain conveyors beneath the grate.

Skop Permohonan & Batasan:
Peralatan ini direka untuk loji simen proses kering dengan tanur berputar. Optimal performance requires consistent clinker granulometry and controlled kiln feed chemistry. It is not suitable for wetprocess plants or for cooling materials with significantly different thermal or physical properties than cement clinker.
