Description
Technical field
It the utility model is related to mineral grinding production equipment, and in particular to a kind of anti-jamming mineral powder production system of grinding machine
System.
Background technology
Zeolite powder, which is that natural zeolite raw ore is levigate, to be formed, and color is canescence., it is necessary to will in zeolite powder production process
Zeolite raw ore is milled by crusher in crushing, and then to crushed stone, is made into the powder for meeting different fineness requirement.
Its specific production procedure is as shown in figure 1, zeolite raw ore is broken for larger stone by coarse breaking machine 1, then through meticulous
Stone is broken into the less fragment of particle by broken machine 2, then fragment is worn into powdery by grinding machine 3, by grader 4 by particle chi
The very little powder met screens, and is put into finished bin 5, and the last packaged packaging of machine 6 is completed to produce, not meeting after sizing screening
It is required that coarse fodder through feed back pipe return grinding machine 3 carry out grinding.
And in the production process of reality, due to worker feeds intake may be too fast, cause in thin broken machine 2 discharging speed compared with
It hurry up so that substantial amounts of fragment enters in grinding machine 3, and the dress for pulverizing fragment is used for when the inner chamber of grinding machine 3 is filled excessive, in grinding machine 3
Putting resistance can become big with the increase of inventory, meanwhile, inventory unstable but it is more when causing feed back amount when few, grinding machine intracavitary
The bed of material increase suddenly, finally result in that the inside of grinding machine 3 is completely stuck, resistance is excessive to be rotated the motor that driving grinding machine rotates because turning round
Or drive belt skidding motor idle running.
Above-mentioned material overfill can cause following three problem：
1. the rotating shaft inside grinding machine is stuck, motor does not skid with belt, and motor load is excessive, fragile motor.
2. the rotating shaft inside grinding machine is stuck, motor and belt slippage, motor idle running produces noise, and belt deformation and part
Overheat causes the life-span to decline.
3. clearing materials inside, it is necessary to by the disassembling shell of grinding machine after grinding machine is stuck, the step is extremely cumbersome,
And waste plenty of time and manpower.
Solving above-mentioned method at present is, compresses belt, increases the contact area of belt and belt plate of electric machine, prevents skin
Band skids, but cures the symptoms, not the disease, and grinding machine still can be stuck, and motor is in high load condition for a long time, under the efficiency that is milled
Drop.Need to arrange for operator to be observed in real time, Field adjustment material pan feeding speed.
Utility model content
The purpose of this utility model is to solve to provide a kind of anti-jamming stone flour production system of grinding machine, pass through material controlling system
System replaces manually being monitored in real time with machine, prevents grinding machine stuck or damages, in the case where not influenceing rate of feeding, effectively
The delivery rate to grinding machine automatically adjust.
In order to realize foregoing invention purpose, the utility model employs following technical scheme：A kind of anti-jamming stone of grinding machine
Powder production system, including coarse breaking machine, thin broken machine, grinding machine, grader and the feed device for material transportation, stone flour production system
Also include feeder and the storage device for receiving thin broken machine comminuting matter, the feeder connection grinding machine feeding mouth and
Storage device；

The drive module, detection module, contrast module and control module, which are sequentially connected, to be connect.
Compared with prior art, the anti-jamming stone flour production system of the grinding machine of above-mentioned technical proposal is employed, is had as follows
Beneficial effect：
First, the material in thin broken machine is stored by setting up storage device, afterwards filled storing by feeder
Fragment material in putting is sent into grinding machine, and the setting of storage device makes the speed that feeds intake unaffected, by rate of feeding and feed
Speed individually separates.
2nd, using the anti-jamming power production system of grinding machine of the present utility model, by being set up in power production system
Material controlling system, the feeding speed of feeder is controlled, when the motor load electric current of grinding machine is larger, then it represents that in grinding machine
Portion's resistance is larger, it is necessary to reduce the feeding speed of feeder, the material in grinding machine is flowed out to reduce resistance；And when grinding machine electricity
When machine load is normal, then feeder normal feed.
3rd, replace manually being monitored in real time with machine by above-mentioned, prevent grinding machine stuck or damage, do not influenceing to feed intake
In the case of speed, effectively the delivery rate of grinding machine is automatically adjusted, reduces human cost.
Because in actual production, grader screens to powder, standard compliant fine powder is exported by fine powder and flowed
Go out, and the larger non-compliant coarse powder of particle is exported from coarse powder through feed back pipe and flowed out, come back in grinding machine to crush again and be in
Thinner powder, returns in grader and is screened, therefore the feed of grinding machine is dual, is on the one hand the fragment of thin broken machine
The opposing party is then the coarse powder in grader, and the feed control for grinding machine is required, it is necessary to which the two aspects are all controlled.
It is advantageous to, the anti-jamming stone flour production system of grinding machine also includes material return mechanism, and the material return mechanism includes
- return pipeline, grader coarse powder is sent back to grinding machine feeding mouth during for grinding machine normal work；

- pipe controller, for controlling grader coarse powder to enter return pipeline or buffering pipeline；
The return pipeline, buffering pipeline are all connected in the coarse powder outlet of grader, and the return pipeline is connected to mill
The feeding mouth of machine, pipe controller are connected with control module.
When grinding machine internal drag is larger, the increase of load of mill electric current, then need to reduce to alleviate into the material of grinding machine
Its resistance, therefore by control module control piper control device, the coarse powder in grader is flowed into buffering pipeline, no longer lead to
Return pipeline is crossed to enter in grinding machine.
The coarse powder of buffering pipeline can be flowed in storage device, can also flow to feed device or other positions are deposited
Cache, preferable in the utility model, the grinding machine includes discharging opening, and discharge outlet is provided with discharge nozzle, the buffering pipeline
It is connected to the discharging opening or discharge nozzle of grinding machine.
