Vertical Roller Mill is Available to Distinctive Materials Necessity

Vertical roller mill also belongs to autogenous grinding group, nonetheless it is different from ore autogenous grinding. In earlier times, pebble media is pebble at river coast, and subsequently, ore block is made use of as media. Because earlier 20 century, pebble mill was efficiently applied to industrial manufacturing, which was a results following enlarging capability to a big extent and eventually manufacturing capability reached the very similar capability of ball mill. Though utilized in industrial manufacturing, pebble mill didn't produce popularly. The reason for that's the grinding method was not simplified, in addition to, it extra media building procedure. Nevertheless, pebble mill even now exists up to now, simply because its products are no iron pollution, and also the assortment index is comparatively excellent, especially in Uranium deposit in ore item treatment method. vertical roller mill application is rather broadly, that is capable to lessen acid consumption in acid leaching. Wet grid ball mill is definitely the similar product, but pebble mill is actually a minor longer than it.

Generally, vertical roller mill is utilized as secondary grinding tools in rod mill and autogenous grinding, which is made use of for fine grinding, and seldom utilized for coarse grinding. On account of smaller energy consumption, reduced production value, conserving metal materials (like grinding media), having the ability to prevent metal pollution, etc. pebble mill is broadly utilized in ore dressing, primarily obtainable to particular material requirement. Due to the fact 1980s, Nordic developed and promoted a style of broken milling process referred to as Autokump, which was offered to standard Rod mill machine or ball mill (for example φ 4.0M X6.0M, and φ 3.2 m X4.5 m) as block mill machine. Instead of metal stick or ball, it uses substantial ore greater than 1OO mm as grinding media to deal with materials less than 30 mm; The particle size and that is between 30mm and 100mm, which can be so-called difficult milling particle as gravel mill media.

In order to facilitate the discharging, block mill discharging port is usually a small larger. In order to enhance productive capability, its diameter is much larger than general mills. The limestone rod mill should be installed on steady concrete groundwork, along with the compression resistance of concentrate foundation should be more than 75%. Before installing, the quality of foundation should be examined so the concentrate would not affect resistance, the quantity and location of prep hole should meet requirements and there is no dust in the prep hole. If adopts the ground wire method, we should prep bury the center label board on the surface of the basic. Before installation, all the center line should be remarked clearly on the center label board on the base to be made use of as the neutral reference. Every part of limestone rod mill should be examined .Any questions should be dealt at once.
