Description
Technical field
The utility model belongs to mining industry grinding attachment field, and in particular to a kind of grinding system that feedwater flow is stable.
Background technique
In ore grinding treatment process, one of which is " two stage grinding+middling ore regrinding ".Specifically, first segment roughly grinds mine
System is made of grate ball mill and high-weir type double spiral classifier closed-circuit operation.During one section of raw ore roughly grinds mine, give
Between 0-10mm, ore is delivered to feed hopper by belt conveyer and enters grinding machine ore particle degree, while adding at feed hopper
A certain amount of to ensure that ore milling concentration reaches 82 ± 1% to mineral water, ore is when passing through grinding machine after by the impact of steel ball, abrasive action
Ore pulp is formed, finally exits into screw classifying system from mill discharge end, and add water management in right amount in exhaust end addition
Graded concentration is 60 ± 2%, because the sinking speed of size fractionated ore is different in classification process, wherein most granularity phases
It is returned to grinding machine to partially thick particle to regrind, the partially thin ore of most of granularity is just discharged into down from classifier overflow weir
One section of thin grinding-classification operation.
Currently, being to carry out mineral water flow control by manually adjusting ball valve switch in thick grinding operation, when raw to mineral water pressure
When variation, mine-supplying quantity change and ore grindability changes, it is difficult to stablize using the method for manually adjusting water supply control valve
Control ore milling concentration reaches normal range (NR), to influence ore grinding stability, it not only results in time in grinding production disorder, production accident
And increase employee and regulate and control productive labor intensity, and be easier to cause that ore milling product is dense, fineness is unqualified, production operation can not be steady
Determine and be unable to reach optimum state, to influence to restrict the raising for selecting factory's production and technical indication and ore grinding processing capacity.
Utility model content
Defect in order to overcome the above technical problems, the utility model provide a kind of ore grinding system that feedwater flow is stable
System.
Its technical solution are as follows:
A kind of grinding system that feedwater flow is stable, including belt feeder, ore grinding waterpipe, ball mill and sensor control
Cabinet processed, the ball mill are provided with feed hopper, and belt feeder, the feed hopper are provided with above the feed hopper
It is provided with ore grinding waterpipe one end, the other end of the ore grinding waterpipe is connected to ore grinding water water source, the ore grinding water pipe
Be provided with electrical ball valve, sensor and electromagnetic flow transmitter on road, the electromagnetic flow transmitter, electrical ball valve respectively with institute
Sensor connection is stated, the electromagnetic flow transmitter, electrical ball valve, sensor are connect with the sensor control cabinet respectively.
The movement velocity of water flow is transformed into induced electricity by this kind design, electromagnetic flow transmitter application electromagnetic induction principle
Gesture is output to sensor, the electric signal for being easy to measure is converted into after sensor is handled, electric signal is by sensor measurement, place
Water flow size is exported after reason.Operator can be by sensor settings ideal water flow signal, through sensing in operating process
Device processing, the valve sensor for being delivered to electric ball, after the processing of electrical ball valve biosensor analysis, automatic identification instruction, and by instruction
Control electrical ball valve motor operating is executed, ball valve aperture is accurately automatically adjusted.Thus forming one, (sending refers to by people
Enabling)-sensor (analysis, processing, send instructions)-electrical ball valve (receives, executes instruction) (the verifying of-electromagnetic flow transmitter
Executive condition and feedback information) automatic water supply system.
When automatic water supply system is run, can as required rapidly, accurately regulating water flow size, moreover it is possible to according to artificially setting
Set throughput and optimal ore milling concentration automatic adjustment feedwater flow size.The grinding system, can rapidly, precisely adjust water supply
Uninterrupted, and the flow adjustment frequency of ore grinding water and flushing water can be reduced, mitigate the labor intensity of operator, while also keeping away
The generation for exempting from the swollen tripe of grinding machine, shutting down, stopping the production accidents such as material, ensure that production normal table.
Preferably, it is provided with cache slot on the ore grinding waterpipe, the top of the cache slot is provided with water inlet, lower part
It is connected to ore grinding waterpipe, the water inlet is connected to ore grinding water water source；Gland, the pressure are provided in the cache slot
Lid is less than the size in cache slot inner horizontal section.
This kind design can prevent the deficiency of water flow caused by insufficient water.Cache slot is only used as when water source supplies water normal
Transfer website, and when water source flow becomes smaller, the water in cache slot can guarantee normal supply ore grinding waterpipe in a period of time.Pressure
Lid can guarantee that cache slot flows into the water flow of ore grinding waterpipe.
