The technique uses natural mica iron oxide ores to manufacture micaceous iron oxide pigments by the main process steps of crushing, ore grinding, separating and drying. The present invention is characterized in that the processes of ore grinding, fractionation and separating are continuously finished once by devices, such as a sand pump, a hydrocyclone, etc. The defects of intermittent ball grinding and multiple times of preparing slurry are avoided. Therefore, the concentration of ore grinding can be well controlled, and the product quality and the product yield are improved.
Description
The present invention relates to a kind of production method of paint pigment.
For a long time, the steel construction surface that facilities such as out of door buildings, bridge the are exposed pigment that need varnish with lacquer is protected to avoid corrosion.Pigment commonly used has inorganic and organic two classes that have.The mineral dye microscopical structure is a particulate state, and the aqueous vapor infiltration rate is big, and the steel surface is still perishable, and pigment dyestuff is easily degraded aging again under solar radiation, and weathering resistance is poor.Recently develop a kind of mica-iron oxide pigment at this situation.The microscopical structure of this pigment is a sheet, and the aqueous vapor infiltration rate is minimum, and is again stable inorganics, has fabulous weathering resistance, is very suitable for being coated in the iron and steel top layer and does protective layer.Mica-iron oxide pigment has two kinds, and the granules of pigments fineness is general red in the following form and aspect of 15 μ m, is called the iron mica red, abbreviates the cloud iron oxide red as.The form and aspect of granules of pigments fineness between 15 μ m～43 μ m are the steel ash, are called micaceous iron oxide gray pigment, are called for short micaceous iron oxide gray.Micaceous iron oxide gray is the major product in the whole production, and the cloud iron oxide red is a byproduct.The production of mica-iron oxide pigment is that the product that utilizes the technics of metallurgy mineral dressing process to obtain in a certain grade scope is major product, present this ore dressing process has four steps: one, ore deposit broken ore, two, stage grinding, three, join the slurry sorting, four, precipitation oven dry, whole process is intermittently discontinuous, is exactly repeatedly to utilize vexed jar of little ball milling ore grinding off and on as stage grinding, reaches sorting again after the suitable fineness.This milling method mainly exists following three kinds of deficiencies, and one, owing to be intermittent type ground ore grinding, therefore to operate and numerously be tired of that the production cycle is long, output does not increase.Two, the every mill of intermittent type ore grinding once needs to join once slurry and reaches certain ore milling concentration, because the raw material granularity of every ball milling is different, so the bad control of ore milling concentration, ore milling concentration control is bad, then grinding particle size can be crossed slightly or meticulous, causes the drop of micaceous iron oxide gray productive rate and the instability of quality.Three, mica-iron oxide pigment causes the feed preparation unit size shakiness thereby makes the quality instability of batch product together by granularity thickness echelon substep in the corase grind final settling tanks.
At the deficiency of above technology, the present invention proposes a kind of method and changes the discontinuous production process of intermittent type into successive closed circuit grinding and classification and sorting production process, to improve the productive rate and the output of micaceous iron oxide gray, guarantees the quality of micaceous iron oxide gray.
Technical purpose of the present invention is achieved in that each process installation hydraulic vortex flow devices behind ore pulverizing, ore grinding, the effect that hydraulic vortex flow devices has the ore particle that granularity is different to separate, hydraulic vortex flow devices has spigot and two outlets of upflow tube, the ore particle that fineness is big flows out from spigot, the ore particle that fineness is little flows out from upflow tube, and the ore particle of different fineness enters different technological processs by processing requirement again.Whole process flow is such: powder ore, ball milling then.The ore particle process sand pump pressurization that ball milling is crossed enters hydraulic vortex flow devices and carries out classification.Granularity reenters the ball mill ore grinding greater than the coarse grain of maximum micaceous iron oxide gray fineness by the spigot outflow, and granularity enters into the sorting of a sorting process flow process less than the particulate of maximum micaceous iron oxide gray fineness from upflow tube.A sorting also is to pressurize with sand pump, the hydraulic vortex flow devices classification, wherein hydraulic vortex flow devices is discharged greater than the ore particle of maximum cloud iron oxide red fineness the ore particle fineness and is entered the secondary sorting process process selectedly from spigot, discharges from upflow tube less than the ore particle of maximum cloud iron oxide red fineness and to enter cloud iron oxide red pigment settling tank.The secondary assorting room is a refining process, used device also is sand pump and hydraulic vortex flow devices, hydraulic vortex flow devices will be discharged to from spigot in the micaceous iron oxide gray settling tank greater than the micaceous iron oxide gray of cloud iron oxide red fineness and precipitate, and the cloud iron oxide red then is discharged to from upflow tube in the cloud iron oxide red settling tank.Cloud iron oxide red and micaceous iron oxide gray are dried at post precipitation, sieving just can obtain mica-iron oxide pigment.
The present invention compared with prior art owing to adopted hydraulic vortex flow devices, makes in the whole technological process ore grinding and classification and sorting closed circuit finishing continuously, so output improves greatly, and operating process is greatly easy.The every mill of intermittent type ore grinding once will be joined once slurry, and method provided by the invention is as long as the ore that fragmentation is good once adds water and is made into certain ore milling concentration and just can, because mine-supplying quantity can be controlled easily, ball mill ore pulp output is also relatively stable simultaneously, therefore once join slurry concentration and just can stablize control, grinding particle size and sorting steady concentration have so just been guaranteed, therefore the productive rate of micaceous iron oxide gray and quality just are improved and ensure that the successive production technique also makes the level of automation of iron mica material production greatly improve.
The present invention is further elaborated below by embodiment.The iron mica ore delivered in 250 * 150 the jaw crusher brokenly, broken good ore is transported to ore storage bin with travelling belt, again by delivering in the ball mill to the barrow band.Joining slurry concentration is 50～70%, and ball mill adopts φ 1200～2400 grate discharge ball mills, and it is 26～35% that ball mill is loaded coefficient, and the anisodiametric steel ball of φ 15m/m～50m/m is housed.Determining fineness with the screening method can discharge the ball mill middling particle during greater than gross weight 85% less than the ore particle weight of 43 μ m, allow ore particle enter into the classification flow process and carry out classification, the classification flow process is utilized sand pump and hydraulic vortex flow devices that fineness is discharged in the ball mill from spigot greater than the ore particle of 43 μ m and is refaced, less than the ore particle of 43 μ m then by entering into the sorting of a sorting flow process in the upflow tube, a sorting then utilizes sand pump and hydraulic vortex flow devices that the ore particle of fineness less than 15 μ m is discharged to the cloud iron oxide red settling tank from upflow tube equally, fineness greater than the ore particle of 15 μ m then by spigot enter carry out in the secondary sorting flow process selected.The same device of secondary sorting utilization is discharged into the cloud iron oxide red of fineness less than 15 μ m in the cloud iron oxide red settling tank, fineness is discharged in the micaceous iron oxide gray settling tank greater than the micaceous iron oxide gray of 15 μ m, respectively the oven dry of the ore particle in cloud iron oxide red and the micaceous iron oxide gray settling tank is just obtained cloud iron oxide red and micaceous iron oxide gray pigment through pulverizing, sieve check then.
