Description
Technical field
The present invention relates to the screening plant technical field of grinding material, and in particular to a kind of discharging for ball mill is sieved
Device.
Background technology
The one kind of cylinder screening device as sieving machine, it is characterised in that sieve is the circle for having many circular holes or square hole
Cylinder.After drum sieve is installed on grinding machine discharging bushing, it is bolted with discharging bushing, grinding machine is done when running with grinding mill barrel to be revolved
Transhipment is dynamic.When ball mill ore discharging is flow on drum sieve, material constantly rolls in drum sieve, and thin rank material is finally from tubular work
Make the sieve aperture on surface by sifting out, coarse-grained material is discharged from the other end of drum sieve.Since drum sieve rotates, and it is
Casement, it does not set further material screening structure, and its protective device will determine that its final material is classified accurate
Degree and rigor.But most of protective covers of existing grinding machine can not then control the classification of screening materials carrying well, so not
The screening circuit of qualified material is easy to be mixed into the undersize material of drum sieve, and then influences the work efficiency of subsequent process flow.
The content of the invention
Go out screening separator for ball mill it is an object of the invention to provide a kind of, it can improve drum sieve packing
The accuracy of separation of material is put, efficiently accomplishes the separation of oversize and screenings, ensures that the good of sieving technology flow stablizes fortune
OK.
To realize purpose as described above, the present invention adopts the following technical scheme that：Dress is sieved in a kind of discharging for ball mill
Put, be equipped with ball mill with the rotating drum sieve of grinding mill barrel, the fine after grinding in material is from drum sieve
Sieve aperture is discharged, and coarse-grained material is discharged from the exhaust end of drum sieve, and the exhaust end of the drum sieve connects one with drum sieve
Rotating waste discharge material screen, waste discharge material screen include the cylindric sieve nest of open at one end one end closing, the opening of cylindric sieve nest
End is docked with drum sieve, and discharge port is offered on the baffle of cylindric sieve nest blind end, and the outside of cylindric sieve nest is equipped with one
The horn mouth docked with discharge port, cylindric sieve nest are internally provided with a reject bin, and the discharge port is located at one end of reject bin,
The inner space of cylindric sieve nest is divided into two chambers by reject bin, is respectively provided with two side plates being oppositely arranged of reject bin
One feed inlet, the material from drum sieve into two chambers is in waste discharge material screen rotary course respectively from the two of reject bin both sides
A feed inlet is dropped into reject bin, and reject bin is internally provided with two inclined plates, and two inclined plates are respectively used to feed from two
The material that mouth drops into reject bin is guided to the reject bin other end by the one end of reject bin corresponding to cylindric sieve nest open end
Discharge port is simultaneously discharged through horn mouth.
Further, the outside of the drum sieve and waste discharge material screen be equipped with closing be used for prevent the anti-of materials from spattering
Shield, the perforate that bell-mouthed flared end is set from protective cover one end are stretched out, and protective cover is bolted by upper lid and lower cover
Form, the bottom of lower cover is equipped with outlet.
Osculum is offered in the circumferential wall of the cylindrical shape sieve nest.
The bell-mouthed necking end is connected to discharge outlet by flange II.
Due to using technical solution as described above, the present invention has following superiority：
The screening plant sealing effect of the present invention is good, and feed separation is powerful, under having effectively completed oversize and having sieved
The separation of thing, prevents discarded steel ball or unqualified material from entering in qualified material pond, influences the piece-rate system of next stage, improve
The separating capacity of cylinder screening device, ensure that sieving technology flow is well stably run.
Waste discharge material screen, horn mouth and drum sieve together rotate, and bulk materials can only be from loudspeaker on such drum sieve
Mouth is gushed out, and comes so that the screening route of unqualified material and qualified material be strictly disjointed, improves drum sieve separation of material
Accuracy, while improve ore grinding screening function, ensure that the technological process of next stage, improve the work of sieving technology flow
Efficiency.
Waste discharge material screen can be dismounted individually with horn mouth, this not only lowers the assembly difficulty of assembler, as vulnerable part
It can at any time be individually replaced, avoid integral disassembly, assembly and wasted caused by wear-out period difference.
