Description

Deironing apparatus in the vertical roll grinder mill
Technical field
The utility model relates to a kind of deironing apparatus, deironing apparatus in particularly a kind of vertical roll grinder mill.
Background technology
Vertical grinder is a kind of large-scale milling equipment, adopts a material bed grinding principle, integrates fragmentation, drying, grinding, classification and carries, and the production efficiency height can be with bulk, graininess, material grinding such as Powdered fineness to the technology requirement.
Along with the accumulation of the rapid progress and the practical experience of material science and other related disciplines, the vertical roller grinder system demonstrates its technology advantage gradually in the material grinding field in recent years.It has reduced specific energy consumption significantly with respect to the ball mill of traditional form, reaches the effect of energy-saving and emission-reduction; And characteristics such as the vertical roller grinder system also has technological design simple, and the technology auxiliary equipment is few, and fixed investment is low.
Owing to, be doped with in the material to the serious irony particulate component of abrasive body abrasion by the grinding material difference, make the abrasive body serious wear, shortened maintenance period, strengthened maintenance cost, also reduced operation rate simultaneously.Especially for slag monomer grinding.Slag is the waste material that produces in the smelting iron and steel, lack the mode of recycling efficiently for a long time, more common processing mode is to carry out slightly broken roughly selecting to reclaiming slag at present, the one-tenth that iron-holder in the slag is bigger sub-elects again as the raw material of smelting iron and steel or as the technology adding ingredient of smelting iron and steel and returns the process for making process, and generally be used to prepare steel slag brick or as the embedding material of road pavement for the part slag of fineness below 50mm, the valuable composition of mass efficient in this part slag can not obtain recycling, and has caused very big waste.
Confirm through overtesting, handling basicity with slag through vexed slag is reduced to after the setting, the slag fine powder characteristic that grinding goes out near or be equal to the grog characteristic of cement, can be used as effective admixture of finished cement, simultaneously country has also put into effect relevant slag cement standard, provides effective rules foundation for being used for cement production etc. behind slag comprehensive utilization and the slag grinding.
The one-tenth of slag is grouped into unstable relatively, and the slag of the different batches in different steel mills even the same steel mill can cause its composition also different owing to the difference of various process conditions, and the variation that this one-tenth is grouped into has also had influence on slag grinding of raw materials characteristic simultaneously.But at least also can retain 2% ~ 5% even more free iron composition and the ferro element that exists with the chemical combination attitude in a large number at the slag composition that finally can be used for grinding, this part material is worth height on the one hand, should be recycled; On the other hand, because its density is big, hardness is big, is difficult to grinding, can be in grinding machine inside after the long-time running, mill liner plate surface produces and pile up, influence the steady production of grinding machine, also can cause serious abrasion, shorten the service life of roller shell, shorten the maintenance period of grinding machine grinding roller, improve the grinding machine maintenance cost, reduce the grinding machine utilization rate.Therefore, in the suitable grinding machine and the outer deironing apparatus of grinding machine is arranged and the technological design of deironing apparatus adds and must consider man-hour slag being carried out grinding.
