LITOVEL, Czech Republic, Aug. 18, 2015 (Press Release) -On July 29, 2015 the company PAPCEL signed a contract with the paper concern NEPA in India for newsprint and graphic paper line modernization. The company NEPA Ltd. is a state paper group, located in Nepangar, Madhya Pradesh state.
The government of India supports modernization of the whole paper line. All tender participants had to meet very strict selection criteria; the selection procedure itself took more than six months. This project is being realized in cooperation with our subsidiary, PAPCEL Pulp and Paper India. The project is also interesting for the fact that a large portion of deliveries and, above all, services will be realized and purchased directly in India from local subcontractors, and our subsidiary will participate in the subcontracting management process.
The paper mill operates two paper machines producing paper of width 5.350 mm on reel. Both machines will produce paper with a substance of 40 - 45 g/m2 for newsprint or 50 - 80 g/m2 for graphic paper. After the upgrade, the PM 1 will reach the output of up to 231 tpd (under the maximum operation speed of 700 m/min) and the PM 2 up to 129 tpd (under the maximum speed of 400 m/min). Both machines are expected to improve significantly the drainage process efficiency in the wet parts. The drying parts will undergo major renovations in order to increase the output and decrease the energy consumption per ton of the paper produced. Apart from the paper machine upgrade, the approach flow system of the PM will be modified and the line for broke processing and the water management system will be supplied.
The upgrade of the first machine will include a repair of the current hydraulic headbox, as well as the cross profile control system. The wire part will be completed with a new high-pressure washing system and ceramic-lined draining elements. Above the wire part, a new threading and trimming water jet will be installed. The top former will be equipped with a new drive roll to ensure an exact synchronization of both wires. The press part of tri-NIP type with an individual pick-up roll will only be complemented with smaller components. A new adjustable vacuum system will enhance the efficiency of the whole wet part and will allow the settings to be modified according to the produced assortment. In the drying part, most drying rolls will be re-grinded and pressure test will be performed. To improve the drive of the drying part, new guide rolls with pins will be mounted, the drying roll stands on the drive side will be modified and the existing cogwheels will be removed. A new steam and condensation system will be installed and the ventilation and recuperation system will be amended. A major part of the threading system will be refurbished and completed; an air threading conveyer will be installed to the end of the drying part. The machine will be equipped with a brand-new multi-engine drive.
At the second machine, the existing high-pressure headbox will be repaired, as well as the cross profile control system. The existing register rolls will be fully substituted by dewatering boxes with ceramic foils. A new threading and trimming water jet will ensure precise cutting of the paper web edges and the threading tail. In the wire part, the stretchers will be replaced and a new high-pressure washing system will be added.
