Vertical roller mills: The new leader in grinding technology

Oct 11, 2019 The VRM, depending on the roller size, has a high reduction ratio; feed from 80 mm to 140 mm to a product of P80 at 75 µm in one pass, the mill is a closed circuit on its own having the comminution and classification of product in a single machine. Sulphide copper-gold ores are usually sorted by flotation.

Advantages and disadvantages of vertical roller mill

Jul 04, 2018 The vertical roller mill has a big feed size (can grind the material with particle size of 5% of the grinding roller diameter: the feed size is generally 40-100mm, and the large vertical mill can reach 120mm), which simplifies the crushing system and saves secondary crushing. (3) The product particle composition is stable, and the raw material
