Weighing belt conveyor replacement: EMCI
Founded in 1990, Est Métal Concept Industrie (EMCI) offers its services in various sectors such as metallurgy, cement, automotive, waterway infrastructure and RMC (Ready-mix concrete) production groups.
Located in Moselle, Ennery, its headquarters consists of a dozen people. The company also has local offices at Poitiers and Luxembourg, and a subsidiary of forty people in Poland.
Interview with Mr. Schneider, Draftsman - Designer within the Design Offices
- What is the background of this construction project?
The project involves the replacement a weighing belt conveyor (steel suspended conveyor that weighs the load on the belt) at the VICAT - BGIE plant of Nancy. The project consisted of creating a new system, longer and with larger troughs (side panels in the shape of a chute) with an increase in flow capacity and reinforced sections.
- What are the main challenges of the project?
The main challenges of the project involved the integration of numerous mechanical parts in a steel assembly.
The existing structure had to be replaced by a longer conveyor and had to be inserted between the existing weighing systems at the extremities of the conveyor.
Also, as part of the plant refurbishment, we did not have the drawings of the existing structure, which required an accurate survey of the site to perfectly incorporate the new structure.
- How was Advance Steel used for this project?
We used Advance Steel for the 3D modeling of the entire conveyor. The steel structure was designed using the software features for placing the bars, the connections between the bars and the multiple folded plates that make up the weighing belt conveyor.
With Advance Steel, we easily integrated into the 3D model the mechanical parts downloaded from the fabricator sites (e.g., Belle Banne® scraper, SKF bearings, roller supports, etc.).
We were also able to obtain all the fabrication drawings automatically and the DXF files, which we sent to the sub-contractor for the fabrication of all the plasma cut parts by CNC machines.
- Could you tell us a few points where Advance Steel specifically helped you?
First of all, I would like to say it was my first project done with Advance Steel and I have only had one training session.
In my opinion, one of the advantages of the software is that the 3D modeling allowed me to better visualize the project. In addition, collision detection (which fully takes into account the objects and elements of AutoCAD® and of Advance Steel) prevented errors in the shop and on site.
In addition, assembly drawings generated by the software and having a nomenclature integrated automatically for each of them, were very clear for the shop which allowed us to save time with a total absence of errors in the fabrication of parts.
Finally, the software's ability to create 3D views and details on the assembly drawings facilitated the understanding of the project for the erectors.
