Abstract
The invention discloses a vibration damper of a large vertical mill body. The vibration damper comprises a vibration damping box which is arranged on an outer shell of a vertical mill device, corresponds to the positions of a powder selecting region and/or a milling region, and is provided with a material inlet and a material outlet; the vibration damping box is internally provided with a damping medium which is one of or is a mixture of a steel ball, an iron block and a stone block at any proportion. A plurality of steel plates are adopted for manufacturing the vibration damping box; the damping medium filled in the vibration damping box consumes partial vibration energy, and the vibration generated by the vertical mill body is reduced to a certain extent; the vibration damper is simple in structure, is convenient to maintain, and can meet the production requirement.
Description
Technical field
The invention belongs to grinding technology field, particularly one large-scale Vertical Mill body vibration absorber.
Background technology
At present, as everyone knows, in grinding industry of today, Vertical Mill has become one of important milling equipment, but Vertical Mill equipment is huge, the diameter of several meters, the height of twenties meters, the heavy-duty motor of a few megawatt, make the grinding roller of Vertical Mill when rolling grinding material, owing to expecting the fluctuating of bed, Vertical Mill produces violent longitudinal direction and oscillation crosswise, one is that moving component in Vertical Mill easily damages as a result, or reduces service life; Two be by Vertical Mill basis by high vibration energy transferring to building nearby, building is also shaken thereupon; Three is that vibration produces large noise, produces harmful effect to surrounding environment.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of large-scale Vertical Mill body vibration absorber, can meet and produce practicality, there is science novelty, the simple feature of structure.
To achieve these goals, the technical solution used in the present invention is:
A kind of large-scale Vertical Mill body vibration absorber, comprise be arranged on Vertical Mill equipment 1 shell body on corresponding to the vibration damping box 2 with feed inlet and outlet of powder-separating area 4 and/or position, district 5 of milling, be provided with resisting medium 3 in vibration damping box 2.
Described vibration damping box 2 is cylinder or cuboid, and volume is less than 10 cubic metres.
Described resisting medium 3 is a kind of in steel ball, iron block and stone or the multiple mixing according to arbitrary proportion.
The specific gravity range of described resisting medium 3 is 2.0 ~ 8.0, and particle size range is 2 ~ 30mm.
The packed space of described resisting medium 3 is greater than 0 and is less than 100%.
Compared with prior art, the invention has the beneficial effects as follows, adopt the vibration damping box that several steel plates are made into, the resisting medium be seated in vibration damping box consumes partial vibration energy, and the vibration that Vertical Mill the machine produces decreases, and this structure is simple, easy to maintenance, can production requirement be met.
