Description
Technical field
The utility model is related to semi-autogenous mill grid plate, and especially a kind of two-way heavier-duty of large-scale mine semi-autogenous mill is wear-resisting
Grate.
Background technology
Grinding machine is the heart of ore processing plants, improves grinding efficiency great to yield effect.Grate wear-out life with
And the grate design being easily installed is to improve the key factor of grinding efficiency.The increase of grinding machine size causes that grinding machine needs protection
Inner surface increase, so as to need to mount and dismount more grates.This causes designer by increasing the size of grate
The quantity of grate is installed to reduce.The grate of semi-autogenous mill is arranged on the discharge end of grinding machine, and grid hole is provided with above, its work
Be can be up to discharging-material size requirement slurry filtration out.The grate of the large-scale semi-autogenous mill of operation is totally tied at present
Structure is：The lifting strip of grate and substrate are overall structure, every piece of lifting strip of grate only one of which vertical direction, and lattice
The quantity of daughter board is more, and this kind of structure has the drawback that：1. every piece of grate only has the lifting strip of vertical direction, and grate is strong
Degree is relatively low, and service life is shorter, increases the machine stop times for changing grate, reduces grinding efficiency.2. this kind of grid board size mistake
Small, installation number is more, and block number is installed when grate is changed excessively, increased machine stop times and the downtime of grinding machine.
In view of the foregoing, the structure of existing grate needs to improve.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided a kind of large-scale mine semi-autogenous mill is double
To the wear-resisting grate of heavier-duty, using the structure of two-way reinforcement, in addition to having lifting strip and increasing intensity in vertical direction, in level
Direction is additionally provided with large number of cross reinforcing increases intensity, greatly improves the intensity of grate, extends and uses
Life-span, total number grate than before reduces one times, greatly reduces the time installed with dismounting grate, and saving stops
The machine overhauling time, greatly improve grinding efficiency.
The utility model to achieve these goals, is adopted the following technical scheme that：A kind of large-scale mine semi-autogenous mill is two-way
The wear-resisting grate of heavier-duty, be by：Substrate, lifting strip, location hole, filter opening, cross reinforcing, butt joint edge, semicircle butt hole
Constitute；Substrate is sector structure, and substrate middle part sets vertical lifting strip, at least two positioning are uniformly distributed on the lifting strip
Hole, the correspondence location hole sets preformed hole on substrate, and filter opening, adjacent two rows filter opening are uniformly distributed on the substrate of lifting strip both sides
Between cross reinforcing is set, horizontal two ends set butt joint edge on substrate, and at least two semicircles are uniformly distributed on butt joint edge
Butt hole.
The cross reinforcing is integrally formed with substrate.
The lifting strip uses integrally formed or separate assembling with substrate.
The filter opening uses slotted hole.
The beneficial effects of the utility model are：When in-site installation grate, substrate is first fixed on the end of grinding machine discharging
Cover, then lifting strip is fixed on substrate middle part, when multiple grates are combined, the butt joint edge correspondence of two neighboring grate engages
Together, semicircle butt hole thereon is formed circular butt hole, lifting strip be fixed at the circular butt hole,
Multiple grates are combined the end cap for being covered with grinding machine discharging according to above step.
The utility model uses the structure of two-way reinforcement, in addition to having lifting strip and increasing intensity in vertical direction, in level
Direction is additionally provided with large number of cross reinforcing increases intensity, greatly improves the intensity of grate, extends and uses
Life-span, and total number grate than before reduces one times, and lifting strip can as needed using integrally formed with substrate
Or split modular structure.The length of each filter opening can be designed according to practical condition, can with it is identical can not also
Together.
With the increase of grinding machine size, because the production loss that shutdown is caused is more and more important.Make the effect of semi-autogenous mill
Rate is maximized, it is desirable to which the service life of grate is tried one's best extension, and installation of the present utility model is with to change grate simple, soon
It is prompt.In order to improve the service life of grate, must just increase the intensity of grate.Installed and replacing grate to save
Time, the quantity of grate must be just reduced, increase the dimension and weight of grate.In addition original two pieces of grates are merged
Into one piece of design, quantity reduces one times than original grate, greatly reduces the time installed with dismounting grate, saves
Maintenance downtime, greatly improves grinding efficiency.The utility model proposes grate structure by grate substrate with carry
Rise bar to constitute, substrate is with lifting strip using Split type bolt the structure closed.Due to increased the cross reinforcing of horizontal direction,
So that the intensity of grate is greatly increased, grate service life is greatly prolonged.The quantity of installing/dismounting grate is effectively reduced,
Effectively increase the service life, reduce the maintenance down number of times of grinding machine.The utility model is simple and reasonable, processing buying is convenient,
Installing/dismounting is facilitated, safe and reliable.
