INTRODUCTION

Within the upgrading program of Ternate production unit, aimed at dealing with increased dust quantity recovered from the dedusting ESP of the kiln line, Holcim (Italia) S.p.A. appointed TEAMNETWORK S.r.l. to realize a dedusting filter for silos 1 and 2 and a dust extraction unit from silo 2, with pneumatic transport to cement silos. Holcim decided to increase the storage capacity of the kiln line, through adaptation of the second silo, which had been previously dedicated to raw meal storage, to storage of clinker kiln dust.

In May 2015 TEAMNETWORK achieved successfully the final test activities of the new fluidization and extraction system related to five cement stocking silos for the Tunisian company Les Ciments de Bizerte. The conclusion of this project, together with the recent completion of a new limestone crushing plant, hit the target of TEAMNETWORK S.r.l. success on the North African market.

Within the kiln maintenance activity scheduled for summer 2014, Holcim (Italia) S.p.A. placed an order to Contimpianti S.p.A. for the revamping of the two filters dedusting the Polysius HAPRA crusher for production of lime- stone that is destined to the raw meal grinding line of the clinker kiln and the additives feeding line to the cement mills.

In May 2014 Contimpianti completed successfully the performance test of the new limestone crushing plant for the Tunisian company Les Ciments de Bizerte.

During the summer period the construction of a “new ferroalloys plant ACC” by Contimpianti SpA TENARIS Dalmine SpA, was completed at the factory in Dalmine, in the province of Bergamo. The ventures were plant engineering, detailed engineering and electrical engineering, supply of materials, removal and installation activities including assistance, and assistance to commissioning.
