Vertical Roller Mill Repair
We can extend the lifetime of VRMs by as much as 100%
In the 70s, vertical roller mills became increasingly dominant for grinding raw materials mainly for the cement industry due to their high energy efficiency and excellent drying capacity. For many years, Castolin Eutectic´s expert know-how, together with our state-of-the-art technologies, have been used to repair VRMs throughout the world, increasing dramatically their lifetimes.
Maintenance and repair of VRMs is a highly technical and specialized business, which should be performed by experts. With the experience gained from repairs worldwide, Castolin Eutectic has developed its own specialized Vertical Roller Mill program, using specialist equipment, highly skilled technicians respecting our specific VRM welding procedure, and a unique TeroMatec EO8338 (open arc) wire developed in-house by our Castolin Eutectic laboratories.
Together with our partners, during the last decades we have proved that preventive maintenance on VRMs can extend the lifetime by as much as 100%. Such VRM maintenance operations have been performed on over 60 VRMs, with 80% of on-site repairs, but also repairs in our workshops.
Our specialists are highly adaptable experts having worked on more than 30 different models of vertical roller mills for more than 20 cement and power companies throughout the world. From small VRMs (roller: Ø 1.65m and table: Ø 2.75m) to huge ones (roller: Ø 3.2m and table: Ø 5.5m), we have worked with most international cement companies. From producers such as Polysius, Loesche or FLS, we have been successful with many types of VRMs.
We are flexible! Jobs on-site or in our facilities
We have general purpose facilities in most countries, all fully equipped with “state-of-the-art” technology, and highly skilled technical specialists. Depending on your request, the job can be undertaken in our own facilities, as well as at your plant. When your Vertical Roller Mill component is too large to be moved for example, our Castolin Services maintenance experts will visit your premises to solve the problem on-site.
Specific equipment installation
Owing to our long experience with VRM repairs, we have developed a special equipment installation, from the traction systems through the earthing points to the power sources and controls. All equipment has been especially designed for VRM repairs.
