Vertical roller mill wikipedia,vertical roller mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, cements and ceramics. It is an energy efficient alternative for a ball mill.
vertical roller mill is a type of grinder used to grind materials into extremely fine powder for use in mineral dressing processes, paints, pyrotechnics, cements and ceramics. It is an energy efficient alternative for a ball mill.As we all know that the vertical roller mill and ball mill can be used in superfine stone powder making, the powder fineness made by ball mill can be controlled between mesh to 400 mesh; however the vertical roller mill process ability can be adjusted between 300 mesh to 3000 mesh, and the more finer powder fineness even can up to 6000 mesh.the energy consumption rate of the ball mill is relatively low. At present, there is a tendency to be replaced by vertical mills, roller presses, etc but the ball mill has a granular shape that is approximately spherical, which is conducive to raw material calcination and cement hydration hardening.
may 05, 2020 vertical roller mill adopts three-dimensional structure,which needs less space,ball mill is just the opposite.and vertical roller mill is cheaper than ball mill,if you dont need high productivity,roller mill is a better choice. think this note,which called what is the difference between vertical roller mill and ball mill can help you.over the last three decades the vertical roller mill has become the preferred mill for grinding of raw materials. the grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. however, despite these benefits,performances of vertical roller mill and closed ball mill circuit in cement grind ing application were compare in terms of energy consumption and
vertical roller mill vertical roller mill integrates the grinding, drying, separation and transportation into one compact unit, thus simplifying the process layout. with an outstanding reduction in energy consumption and metal abrasion. compared with traditional ball mill, vertical roller mill can make significant contribution to customers jul 18, 2016 several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses and clinker pre-grinders with ball mills. ball mills have been the traditional method of comminution in the mineral processing industries and continue to operate with old generation vertical roller mill VS ball mill first of all, from the appearance point of view, there is a big difference between the vertical mill and the ball mill. the vertical mill is presented vertically and three-dimensionally from the ground, while the ball mill is lying horizontally on the ground and covers a relatively large area.
