Abstract
The invention relates to a ball mill cooling method capable of dedusting a crushing workplace. According to the method, a ball mill comprises an induced draft fan, wherein an air outlet of the induced draft fan is communicated with an inner cavity of a cylinder body of the ball mill through an air pipe; a plurality of air inlet pipelines are communicated with the air inlet of the induced draft fan; an air inlet of each air inlet pipeline is formed in the crushing workplace; and when the cylinder body of the ball mill needs to be cooled, the induced draft fan performing air suction on the crushing workplace and forcible air cooling on the inner wall of the cylinder body, and the dust is adsorbed in slurry in the cylinder body of the ball mill. Through the adoption of the method, the cooling time of the ball mill can be shortened; the grinding efficiency of the ball mill is improved; the crushing workplace can be dedusted; and the production is improved.
Description
Technical field
The present invention relates to a kind of ball mill cool-down method, specifically a kind of ball mill cool-down method that can be to the dedusting of crushing operation place.
Background technology
Ore reduction operation place dust is serious, in certain area, staff only wears aerial respiration machine just can enter workplace operation, through precipitation after a while, on ground, can pile up a thick layer of breeze around, to production, bring very large inconvenience, need to arrange personnel regularly to clear up.
Crushing operation site space is more limited, and a large amount of dust precipitate in region, and labor cleaning's required time is longer, has affected the continuity of production system.Secondly this dedusting method needs personnel to enter place, to health of human body, brings harm, and the breeze cleaning out in addition, in the process of transportation, brings environmental pollution also can to periphery place.
And in grinding operation place, ball mill is when in when operation cylindrical shell, temperature reaches 70～80 ℃, grinding effect declines, to such an extent as in ball mill barrel, grinding operation has been difficult to, must first be cooled to 40 ℃ of left and right, and ball mill naturally cools and need consume the plenty of time, approximately 4 hours, greatly affected repair schedule.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, a kind of ball mill cool-down method that can be to the dedusting of crushing operation place is provided, not only can shortens the time to ball mill cooling, improve ball mill operating efficiency, can also remove crushing operation place dust, improve production environment.
The present invention has adopted following technical scheme: comprise an air-introduced machine, fan out draft communicates with ball mill barrel inner chamber by airduct, the intake stack that several communicate with fan inlet, and the air inlet of every intake stack is arranged on crushing operation place; When ball mill barrel need to be lowered the temperature, air-introduced machine carries out air-breathing by one or several intake stack to crushing operation place, there is the air of crushing operation place dust to send in ball mill barrel absorption, cylinder inboard wall is carried out to air blast cooling cooling, air is when the water curtain of the slip formation through in cylindrical shell, and dust is adsorbed and is retained in the slip in ball mill barrel.
Further, every intake stack is provided with horn-like air inlet in crushing operation place, can improve pick-up performance.
Preferably, on every intake stack, valve is housed, can selects as required the place dust suction of corresponding crushing operation.
The present invention adopts air blast cooling way to lower the temperature to ball mill, can shorten the time to ball mill cooling, improves its grinding efficiency; In addition, air-flow also can be removed the tamper on compartment plate hole when through partition panel, improves ore grinding performance; Meanwhile, the negative pressure that air-introduced machine carries out can be adsorbed the dust in crushing operation place, can improve the production environment in crushing operation place, improves the continuity of crushing operation; The dust being siphoned away by air-introduced machine is absorbed while passing through ball mill, does not need to set up in addition cleaner, good dedusting effect.
Accompanying drawing explanation
Fig. 1 is technological principle schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, the air outlet of air-introduced machine 2 is by airduct 3, by charging aperture 11 places of ball mill, communicated with cylindrical shell 1 inner chamber, and air-introduced machine 2 air inlets are provided with three intake stacks in parallel 4,5,6, and the air inlet of every intake stack is arranged on crushing operation place; On every intake stack, valve is housed.
For improving pick-up performance, every intake stack is provided with horn-like air inlet in crushing operation place.
The quantity of intake stack is looked crushing operation place quantity and is determined, each crushing operation place can be in batches or dust suction in turn.
Also can arrange two to three intake stacks in a crushing operation place, to improve the pick-up performance to this place.
Start ball mill, when ball mill barrel 1 temperature reaches 70～80 ℃, starting air-introduced machine 2 carries out air-breathing by one or several intake stack to crushing operation place, there is the air of crushing operation place dust to send in ball mill barrel absorption, cylinder inboard wall is carried out to air blast cooling cooling, air is when the water curtain of the slip formation through in cylindrical shell, and dust is adsorbed and is retained in the slip in ball mill barrel.
Claims (3)
1. ball mill cool-down method that can be to the dedusting of crushing operation place, comprise an air-introduced machine, fan out draft communicates with ball mill barrel inner chamber by airduct, the intake stack that several communicate with fan inlet, and the air inlet of every intake stack is arranged on crushing operation place; When ball mill barrel need to be lowered the temperature, air-introduced machine carries out air-breathing by one or several intake stack to crushing operation place, there is the air of crushing operation place dust to send in ball mill barrel absorption, cylinder inboard wall is carried out to air blast cooling cooling, air is when the water curtain of the slip formation through in cylindrical shell, and dust is adsorbed and is retained in the slip in ball mill barrel.
2. ball mill cool-down method that can be to the dedusting of crushing operation place according to claim 1, is characterized in that: every intake stack is provided with horn-like air inlet in crushing operation place.
