vertical roller mill handle tough materials

vertical roller mill 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.

A vertical roller mill is a type of industrial equipment used to crush or grind materials into small particles. These machines consist of a large, heavy-duty steel drum that relies on both hydraulic and pneumatic forces to pulverize rock or stone. Vertical roller mill machines are widely used in the concrete and mining fields, and are also used to process gypsum. These units can process both raw and recycled materials, while helping to reduce waste and preserve virgin supplies of these materials.

Most vertical roller mill models are positioned beneath a large hopper, which feeds rock and other materials into the top of the mill. A large, horizontal plate fits within the body of the drum, and rotates very rapidly when the machine is in use. As materials fall onto the plate, centrifugal force pushes them out towards the edges of the circular plate. Large rollers sit along the perimeter of the plate, crushing and grinding materials before they can fall off the edge. These rollers are powered by hydraulic fluid, which enables them to exert tremendous force to handle tough materials.
