A watermill or water mill is a mill that uses is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or processes are needed in the production of many material goods, including flour, lumber, paper, textiles, and many metal products. These watermills may comprise gristmills, sawmills, paper mills
Vertical mills Flexible mills with integrated separator. The vertical mill enables high energy economy, and convinces with low specific wear values. Drying of the feed material, grinding, separating, and material transport take place inside the mill. It is thus especially well suited for grinding products with high proportions of wet components.
Every mining operation has a unique grinding process. has experience of over 8,000 grinding mills globally, including manufacturing and delivering the largest SAG/AG mills in the world. Our experts welcome the opportunity to assist you with circuit and circuit control design as well as startup, operation, and optimization of your mill.
A Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill.
The mills themselves are large rotating cyclinders, ten to fifteen meters in diameter, grinding hundreds of tons of ore per hour. For effective grinding, these mills have to rotate at low speeds. The motor capacities are as high as 15 to 20 MW for such an application.
autogenous grinding mills that are used in mines to finely crush ore material for mineral separation. A new and improved system was needed by a major manufacturer of grinding mills that was using the only inching drive available in the marketplace to facilitate selective rotation of mill cylinders at reduced speed for startup and maintenance work.
