Add materials and collection to take material convenient, easy to operate, safe and reliable, partition size is high, it is adaptable to-74 μm particulate wholegrain level things
Material 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 grain
Level 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, clasfficiator at different levels is entered 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
Size of data (data can be roughly herein), medium (water) i.e. by silica gel tube through feed mouth, enter little funnel, then through silica gel
Pipe, lucite tube etc. enter clasfficiators at different levels, make clasfficiator at different levels all fill medium, afterbody (the thinnest one-level point
Level material) 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 the most slowly and carefully adds in little funnel, notices that it contains the flow of fine fraction ore pulp and now digital display micro constant flow pump
The resultant of confluent 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, digital display micro constant flow pump is adjusted
Confluent, to confluent when determining classification, the most i.e. enters 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 by the material in wet elutriators at different levels
Release, 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 free settling in medium (water)
Rule, utilizes identical upward-current, in the classification pipe of different-diameter, produces different ascending water speed, make granule materials by
Its different sedimentation velocity, is divided into several ranks, the product of each rank, is all the grain group equal by sedimentation velocity
Becoming, sedimentation velocity 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, generally use water
During for 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 confluent of the flow containing fine fraction ore pulp and now digital display micro constant flow pump
Resultant must be less than confluent when determining classification, to prevent determinand material to be mixed into graded product relatively fine because flow is excessive
In the clasfficiator of level.
4, wet elutriators at different levels are designed as the clasfficiator of Quick-detachable cleaning and can dismantle conveniently by rotation, then clean it
Inwall, is 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,
The inner edge of upper clasfficiator body has female thread, the outer rim of lower clasfficiator body to have external screw thread, by silica gel sealing ring between both
Seal, 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 by the material in wet elutriators at different levels
Release, and with the collection of material after suitable container collection, beneficially classification.
