1. PEMBUKAAN PAINPOINT DRIVEN

Menguruskan peringkat akhir penyejukan klinker adalah kesesakan kritikal dengan akibat langsung untuk keuntungan tumbuhan. Operasi penyejuk klinker yang tidak cekap membawa kepada kehilangan haba yang berlebihan, reducing thermal energy recovery for your preheater and calciner systems. Uncontrolled quenching can result in poor cement quality and increased wear on downstream equipment like crushers and conveyors. Frequent maintenance stops for refractory repair or grate replacement cause unplanned downtime, directly impacting your production tonnage and bottom line.

Are you facing high secondary air temperatures, inconsistent clinker bed permeability, or rising specific power consumption at your mill? Is your current cooler struggling with varying feed rates or producing clinker with residual heat that stresses material handling systems? The solution requires a system engineered not just to cool, but to optimize the entire thermal and mechanical chain.

2. GAMBARAN KESELURUHAN PRODUK

The Parut Penyejuk Klinker is a reciprocating, airpermeable bed system designed for efficient heat recovery and quenching of cement clinker exiting the rotary kiln. Its operational workflow is defined by controlled, staged cooling:

1. Controlled Infeed: Klinker panas (approximately 12001400°C) from the kiln is evenly distributed across the cooler grate.
2. Staged Air Quenching: Highpressure cooling fans force ambient air upward through the moving grate and clinker bed in multiple zones, enabling precise temperature control.
3. Pemulihan Haba: The heated secondary air is directed back to the kiln combustion zone, while tertiary air is supplied to the calciner, significantly improving kiln system fuel efficiency.
4. Clinker Transport & Pelepasan: Reciprocating grates convey the cooled clinker (below 100°C + ambien) to the discharge end for transfer to the cement mill.
5. Fines Handling: A dusttight casing and integrated drag chain conveyor manage cooler fines (grate spill).

Skop Permohonan: Ideal for medium to largecapacity dryprocess cement plants with rotary kilns. Batasan: Prestasi sangat bergantung pada granulometri klinker yang konsisten; not suitable for wet process plants or very lowcapacity operations without significant design modification.
