It is convenient that material and collection take material, easy to operate, safe and reliable, partition size is high, it is adaptable to-74 μm particulate wholegrain level materials
Fine graded and separating effect is good.
Work process:
1, set-up procedure: according to the granule size of material to be fractionated, first uses standard screen wet screening, screens out+74 μm coarse fractions
Material, obtains-74 μm fine-graded wholegrain level material, and actual elutriation sample size is 60～100g；Measure determinand
Density δ of material, determines confluent during classification.
2, Simple And Practical wet elutriator is connected as illustrated, and adjust the height of telescopic lever, to enable media to smoothly,
Enter clasfficiator at different levels glibly.
3, the water inlet end of digital display micro constant flow pump is opened, and the control handle of regulation digital display micro constant flow pump is to above-mentioned confluent data
Size (data can be roughly herein), medium (water) i.e. by silica gel tube through feed mouth, enter little funnel, then through silica gel tube,
Lucite tubes etc. enter clasfficiators at different levels, make clasfficiator at different levels all fill medium, afterbody (the classification material of the thinnest one-level)
Outlet collected by collecting vessel.
4, the confluent of digital display micro constant flow pump is reduced, by aforementioned off-the-shelf fine particle stage material slurry to be measured, stirring
One side slowly and carefully adds in little funnel, notices that it contains the feedwater of the flow of fine fraction ore pulp and now digital display micro constant flow pump
The resultant of amount must be less than confluent when determining classification.
5, until all being added after wet elutriator through little funnel by fine particle stage material slurry to be measured, the feedwater of digital display micro constant flow pump is adjusted
Measure to confluent when determining classification, the most i.e. enter the continuous analysis phase.
6, general continuous analysis time is 6～8 hours, and needing according to classification can proper extension continuous analysis time.
7, after analysis process terminates, close digital display micro constant flow pump, stop feedwater.
8, by disconnecting the silica gel tube between wet elutriators at different levels and lucite tube, successively the material in wet elutriators at different levels is released,
And with suitable container collection, after precipitating, be dehydrated, drying, each grade material after classification can be waited until.
Operation principle:
1, Simple And Practical wet elutriator (or claiming continuous wet elutriator) is according to granule materials rule of free settling in medium (water),
Utilize identical upward-current, in the classification pipe of different-diameter, produce different ascending water speed, make granule materials different by it
Sedimentation velocity, be divided into several ranks, the product of each rank, be all made up of the grain group that sedimentation velocity is equal, sedimentation
Speed is often calculated by quartz density.
2, measuring density δ of material to be measured, quartz density presses 2.65g/cm3Calculate, if Media density is ρ, with water be generally
During medium, take ρ=1.00g/cm3.Now, according to Q=(δ-2.65) * 100ml/min, confluent during classification is determined.
When 3, adding material to be fractionated, the resultant of the flow containing fine fraction ore pulp and the now confluent of digital display micro constant flow pump
Confluent when determining classification must be less than, to prevent determinand material to be mixed into dividing of the relatively fine one-level of graded product because flow is excessive
In level device.
4, wet elutriators at different levels are designed as the clasfficiator of Quick-detachable cleaning and can dismantle conveniently by rotation, then clean its inwall,
Be conducive to keeping the cleaning of clasfficiator inwall at different levels, it is simple to effectively observe classification phenomenon and supervision classification process.
5, the clasfficiators at different levels of Quick-detachable cleaning are made up of upper clasfficiator body, lower clasfficiator body and silica gel sealing ring, upper point
The inner edge of level device body has female thread, the outer rim of lower clasfficiator body to have external screw thread, sealed by silica gel sealing ring between both,
Both can effectively seal, prevent medium excessive, and can dismantle easily, clean and clean again.
6, by disconnecting the silica gel tube between wet elutriators at different levels and lucite tube, successively the material in wet elutriators at different levels is released,
And with the collection of material after suitable container collection, beneficially classification.
