Description
Technical field
The present invention relates to a kind of preparation method of ball milled powder, specifically relate to a kind of preparation method who makes the powder of carbon anode for aluminum.
Background technology
In the prescription that aluminum carbon anode is produced, the ball milling powder accounts for about 30% of siccative, but its surface area accounts for more than 90% of total surface area, binding agent allocated into measure decisive role, and the fluctuation of powder tends to directly have influence on the anode appearance qualification rate, the method of the powder that present domestic production carbon anode is used is after separating through the coarse grain separator from the powder that ball mill is produced, qualified material is drained in the finished powder storehouse after being collected by cyclone dust collectors, after entering into the ball mill head by the systemic circulation blower fan again, the power wind that the drive powder advances in the system circulates once more, whole system is carried out under positive pressure, therefore the time one is grown leaking out in the system, it is unavoidable leaking the material phenomenon, cause the site environment dust content excessive, inclement condition, totally unfavorable for operating personnel's health.Used in addition coarse fodder separator, inferior separating effect makes a large amount of accepts turn back to the reduction that ball mill causes output.The control of finish fineness and adjusting difficulty, because the structure of traditional coarse grain separator and the restriction of classification principle, the adjusting of finish fineness and control are main to be undertaken by the angle that changes baffle plate, the mutually mixed phenomenon of thickness powder is serious, and is unfavorable for the fineness control of powder.At the blowback wind sleeve formula dust-precipitator of air outlet configuration, the cleaning of blowback wind causes the blanking of the powder that gathers dust inhomogeneous for discontinuity, causes the fluctuation of powder in the filler bin.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiency that prior art exists, and provides a kind of and stops to make powder production and leak out under positive pressure and expect phenomenon, makes the preparation method of the powder of the making carbon anode for aluminum that whole system produces under negative pressure.
A kind of preparation method who makes the powder of carbon anode for aluminum of the present invention comprises that the preceding storehouse of ball milling, batcher, ball mill, efficient rotor formula grader, bag filter, finished powder storehouse constitute, described preparation technology's flow process is: raw material is sent into ball mill in the preceding storehouse of ball milling through batcher and is pulverized, the powder of producing through ball mill is through the classification of efficient rotor formula grader, gather dust through bag filter again, be drained into the finished powder storehouse and get product.
The preparation method that the present invention makes the powder of carbon anode for aluminum compared with prior art has following beneficial effect: the present invention is the endless form that adopts a kind of open circuit, and whole system is carried out under negative pressure.Main technique arranges that content is to arrange a main air blower at the least significant end exhaust outlet of production line, to provide system's operation required air quantity, under the drive of system's wind, carry out classification through the powder that ball mill is produced through a kind of efficient rotor grader, product after qualified is through after the bag filter of arranging on the production line gathers dust, be drained into uniformly in the finished powder storehouse, carry out emptying through behind the main air blower through the wind that reaches the discharge standard requirement after gathering dust.This system process is arranged simple, smooth, and pipeline is short, and system pipeline leaks out and obtained tangible improvement; Do not relate to the systematic air flow assignment problem, convenient operation and control; System is in negative-pressure operation completely, can effectively solve in the original system because of leaking out of causing of malleation to emit grey phenomenon, reduces common and numerous dust pollution, has improved the work situation in workshop; The purity of producing the required ball milling powder of aluminum carbon anode is uniform and stable, has reached the requirement of producing.
Preparation method's the advantage that the present invention makes the powder of carbon anode for aluminum is:
1, system process is arranged simple, smooth, easy to operate;
2, system is in negative-pressure operation completely, can effectively solve in the original system because of leaking out of causing of malleation to emit grey phenomenon, reduces common and numerous dust pollution, has improved the work situation in workshop;
3, with the reasonable disposition of efficient rotor grader and bagroom, improve output, the purity of even powder, finished powder fineness good uniformity has obviously improved its quality;
4, system adopts a kind of efficient rotor grader to improve the selection by winnowing efficient of ball milling powder, can also adjust for the purity of ball milling powder according to the production demand in addition in good time.The purity adjustment range of finished powder is wide and sensitive, and system controllability and measurability obviously improves.
The inventive method is applicable to that aluminum carbon anode produces the transformation of old system in the production process of required ball milling powder, is equally applicable to newly-built companion produces required ball milling powder with carbon anode production system.
