Description
Technical field
The utility model is related to a kind of ball mill ball-sending devices, belong to preparation equipment field.
Background technology
Ball mill is the equipment that ore is continued to crush after crusher, to obtain the thinner product of granularity, its powder
The broken reduction ratio than various other crushers is much greater, and usually 200~300, can also it increase under particular case, therefore ball milling
Machine is applied to the final stage comminution process before ore beneficiation, and the raising of its efficiency plays to pass weight the whole flow process of ore dressing
The effect wanted.
The ball mill that traditional ore dressing plant uses enters mill amount and is up to 6000 tons daily.With the continuous improvement of output, ball milling
Machine worn steel ball is fairly obvious, and the steel ball of serious wear is discharged into the discharging of ball mill body from ball mill body and through ore discharge grid
When mouth or discharge end flase floor serious wear, steel ball also can be discharged into ball mill body from ball mill body and through ore discharge grid
Discharge port is finally directly entered grader trough, and the steel ball run out of is contacted with the big and small blade of grader, seriously affects grader
Service life.
To solve the above-mentioned problems, my company technique personnel devise a kind of spiral sieve of taper, and the spiral sieve structure is such as
Shown in Fig. 4, formed by a round steel screw processing.The operation principle of spiral sieve is as follows：
Wet type grate ball mill is often mixed with water to mine, and enters ball through hollow axle journal by ore feeder
In grinder body.Water can make to give mine normal operation, and can help ball mill distribute ore, promote qualified products soon with
The flowing of water is overflowed from the hollow axle journal of ore discharge.The steel ball in cylinder is taken out of by overflow in order to prevent, is installed in ore discharge hollow shaft
Spiral sieves, and the rotation of ball mill body drives spiral sieve rotation, when steel ball is taken to by overflow at neck of hollow shaft spiral sieve, with
Ball mill rotation drives the rotation of spiral screen device, i.e., the steel ball in spiral screen device is spued.
But this spiral sieve can have the following problems when producing and using：
1, round steel being subjected to screw processing, processing technology is complicated, and making is time-consuming and laborious, and the grasp of processing and fabricating size is bad,

2, wearing no resistance for the ease of the machine-shaping of spiral sieve, the material selection Q235 steel of round steel, but Q235 steel,
In actual application, easily wears, therefore service life is short, need to be replaced frequently, maintenance maintenance is of high cost；
3, the screen slot of the spiral sieve of gained is 25mm or more after processing, and bead in ball mill can still be caused to be flowed into classification
Machine influences next process；
4, it is rotated with ball mill body because spiral is sieved, when steel ball is sieved by spiral, is easy a circle circle along spiral sieve
Spiral moves, and causes steel ball stroke long, is not easy to be discharged in sieving from spiral, using effect is not good enough.

Work manufacture is more convenient, and processing and fabricating size can ensure the spacing between spiral sieve adjacent grill convenient for holding；Spiral
The spiral guiding plate on inner wall is sieved, facilitates and the steel ball come out in ball mill is discharged；In the utility model between adjacent grill
Spacing be 10-20mm, to make the sizes of balls flowed out in ball mill can enter ash can, ensure that spiral sieve use effect
Fruit avoids steel ball from flowing into grader, extends the service life of grader, while improving the efficiency of classification machine equipment, reduces
Maintenance cost reduces the workload and labor intensity of maintenance personal, has prodigious application value.
Preferably, several installation otic placodes are fixed on the outer wall of spiral sieve, each otic placode of installing passes through corresponding company
Extension bar is fixedly connected with the ore discharge discharge port of ball mill body, and each mounting ear plate is uniformly distributed.It is further preferred that the company
The both ends of extension bar have thread segment, the setting on the ore discharge discharge port of installation otic placode and ball mill body of corresponding every connecting rod logical
Hole, the thread segment at connecting rod both ends are each passed through the through-hole on the ore discharge discharge port of corresponding installation otic placode, ball mill body, and
It is fastened respectively by fastening nut.Form is convenient for that spiral sieve is installed and dismantled with this configuration, is sieved convenient for spiral
Maintenance maintenance.
Preferably, spiral sieve uses segmentation structure, is formed by connecting by large and small two sections of grid type conical screens, big grid
The outer toroid of formula conical screen is identical as the small diameter of interior annular of grid type conical screen.The spiral sieve of this segmented is convenient for
It manufactures.
Preferably, the grizzly bar is round steel.It is further preferred that the material of grizzly bar is No. 45 steel, wearability enhancing, from
And the service life of spiral sieve can be extended.
Possessed advantageous effect is the utility model compared with prior art：
Spiral in the utility model sieves convenient processing and manufacture, and convenient for holding, spiral sieves on inner wall processing and fabricating size
Spiral guiding plate can facilitate the discharge of steel ball in ball mill；Spacing in the utility model between adjacent grill is 10-
20mm makes the sizes of balls flowed out in ball mill that can enter ash can, avoids steel ball from flowing into grader, extend making for grader
With the service life, maintenance maintenance cost is reduced, there is prodigious application value.
