From scrap to a product crafted for longevity.

Since 1926, Fonderia Gelli has specialized in crafting alloys, notably resistant to wear and heat, tailored for the cement and mining industries.


Study of process parameters

Design and implementation of comprehensive linings, both for new grinding installations and for adapting to existing setups, conducting on-site assessments and applying tailored “ad hoc” solutions.”


Design and alloy selection

In-house analysis laboratory equipped with cutting-edge instruments for the development of new alloys (specifically designed for the most critical applications) and for comprehensive quality checks on every type of part to be produced.


Assembly Supervision

Supply of materials used in the assembly and commissioning of installations (fasteners, carpentry, rubbers, resins, accessories, etc.) with the option to avail of a team of assembly supervisors capable of providing qualified assistance.


Periodic Monitoring

Scheduling of regular audits to verify performance and report any wear.

Research and development

Fonderia Gelli produces armors for mills and wear castings for crushers and various types of grinders, replacement parts in refractory steels for furnaces and coolers, starting from construction drawings, field surveys, or from a sample.

The Reverse-Engineering service allows for a full characterization of a casting both at the chemical level and in terms of physical and mechanical properties. From here, the process moves on to design, production, and installation.

The in-house laboratory has been pursuing research for years to optimize existing alloys and to develop custom ones for application to products.

The laboratory is equipped with both melting and treatment furnaces, and all the necessary instrumentation for material studies, such as:

  • Brinnell and Vickers hardness control machines, tensile and resilience testing machines,
  • water jet and electroerosion cutting machines,
  • instrumentation for metallographic and chemical analysis.
