REPUBLIC CEMENT CORPORATION - LINE 5 PHILIPPINES - NORZAGARAY
The total cost of the works is 75,000,000 USD HT.
Cement production capacity: 1,000,000 tons/year.
In 1993, RCC contracted to PEG a feasibility study investigation for the installation of a new line in their Norzagaray cement plant. Different scenarios were studied to find the optimal solution corresponding to the limited budget. In 1994, the Owner chose the solution of a new 3300 t/day kiln line including limestone crushing and raw meal grinding. A new raw meal silo, clinker silo and storage hall were integrated into the plant. DETAILS: The existing limestone hall was extended for a higher capacity and an on-line analyzer was installed. An existing limestone crusher was relocated and installed for the use as additive crusher. The cement grinding capacity was increased by a new 100 t/h cement mill with low energy consumption and by increasing the capacity of an existing ball mill by the installation of a second-hand pregrinder. A multi-cell cement silo was installed for the intermediate storage of different cement qualities. The cement dispatching capacity was increased by two new 8-spout rotary packers and a 4-line truck loading station.
Dust emission were reduced below 50 mg/Nm3 dust by the installation of electrofilters for the kiln line and bagfilters for crushing, cement grinding and material handling. Well known German, French and USA suppliers were chosen to deliver the main equipment in various packages. To keep the importation costs low, equipment was fabricated to a high extent locally, based on supplier drawings and interconnecting components were designed and constructed by PEG. The scope of PEG's equipment design and supply included clinker silo, multicell cement silo with feed and extraction system, hot gas generators for raw and finish mills, ducting for raw and cement mill. In spring 1995, the site was opened. In summer 1997, the plant was commissioned under PEG's supervision and the preliminary performance test was successfully passed.
