Description
The utility model is a kind of laboratory sample comminutor, possession matter technical field specimen preparation category.
The grade of gold deposit geology sample is most to restrain several grams (10 for every zero point is several
-3-10
-4%), in geochemical exploration, the detectability of gold reaches p.p.b. magnitude (10
-7%), and gold often is present in the sample with natural monomer independently, and its distributed pole is inhomogeneous.Gold is very big with physical property (as hardness, toughness, the density etc.) difference of gangue in the sample.Each breadboard crusher is the main broken acting force with impact and extruding all at present, though the crushing efficiency to rock is very high, yet can not adapt to, exist selective crushing during broken sample rusty gold with excellent toughness, in the sample that makes, gold is enriched in the coarse fraction part.Because the simple ore composition granule rareness of gold, thereby can't evenly disperse, cause curtailed sampling to lose representativeness, cause the result of laboratory test fluctuation.Bring very big difficulty for calculation of reserves and anomaly evaluation, influence prospecting result.
In order to address this problem, the past has the people to carry out many researchs, and some laboratories are adopted and strengthened division sample particle diameter
［ 1 ］, prolong the ore grinding time
［ 2 ］Etc. method, hope is crushed to the superfine uniformity coefficient that improves sample with sample, be subjected to the restriction of impact extruded formula disintegrating machine performance, can't avoid the selective crushing of gangue in the sample and rusty gold and be crushed to stifled sample and the bonding that the gangue of shale causes earlier, retardance is to the further pulverizing of gold.Therefore said method can only be effective to a certain extent.Some laboratories have stipulated that necessary use 200 eye mesh screens sieve, to guarantee the processing granularity of gold in the sample.Yet,, can not solve the equally distributed problem of gold in sample even all passed through 200 eye mesh screens to the geochemical sample of little gold.Here calculate the volume of goldc grains with 200 eye mesh screen aperture φ 0.074mm, deduct factor in irregular shape, 1/3rd weight of calculating goldc grains by volume.When getting 10 gram samples,, just will cause the error increment of 100p.p.b. as long as account for a gold more.Use the catastrophic fluctuation of result of laboratory test of such sample gained also not at all surprising
［ 2 ］Document
［ 3 ］Once existing laboratory crusher had been carried out detailed research, through advantageous embodiment, improve the mill of machine and carved fragmentation power, fragmentation to rusty gold in the sample has had tangible improvement, improved sample system amount, but, little aurification is visited sample still can not fundamentally overcome above-mentioned difficulties owing to be subjected to the restriction of Machine Type.The и of the Soviet Union. я. к о р о т а
в а has delivered in nineteen eighty-two and has utilized planetary centrifugal mill, the gold in quartz vein gold mine and the gravity tailings can be crushed to the paper of 0.001-0.016mm
［ 4 ］The geology sample does not possess whole hard quartz or the conditions of having separated thin and light and soft mineral through gravity treatment of belonging to of sample.The structure of planet centrifugal mill does not possess the technical characteristic of eliminating above influence fully yet.The author once verified on the planet centrifugal mill with general gold deposit geology sample, all can't reappear above-mentioned good index.
The basic reason that each laboratory crusher of old type is difficult to scrap is as follows:
1. previous model is based on impact extruded power, and it has higher crushing efficiency to hard brittle rock, yet impact extruded can only be flattened gold but be not broken.Rusty gold in the broken sample mainly acts on as the on-stream mill to gold of abrasive material by contained hard gangue in the sample quarter, and along with hard gangue quilt is preferentially levigate, the ability that its mill is carved gold also weakens gradually and loses.
2. porphyrize to the gangue of pelitization will block the fragmentation to gold.
3. there is content extremely low (10 in gold with rusty gold independently in the sample
-6-10
-9), the simple ore composition granule is relatively very rare, but there is the selective crushing to gangue in previous model, and the fragmentation of gold lags behind, and makes that the gold in the sample is enriched in the coarse fraction part after the processing, is difficult to even distribution.
4. Jin density is than big about 7 times (19/2.7) of rock, and with the method for the control particle diameter that sieves, the grain anharmonic ratio gangue recuperation of gold is many, and its error increment is corresponding also much bigger.
5. mill machine engraving gold power is strong, but compole is short during the simple grain grind away; Rod mill is a continuously grinding, but it is slow to carve golden efficient.
Based on above reason,,, problem do not break through but obtaining essence yet though make moderate progress through studying the sampling machine performance in many ways.
The preparation that therefore little aurification is visited sample is still a current technical barrier.
The purpose of this utility model provide a kind of can be with the crusher device of the rusty gold ultra-fine grinding in the sample.
The utility model provides the crusher device of the diverse novelty of a kind of and original all kinds of crushers for this reason, it is made up of feeder hopper, crushing chamber, wind-force tripping device and setting chamber, feeder hopper has closed continuous flow rate device, abrading block in the crushing chamber and wall and the end, are the friction motion, are separated to the particle diameter of the sample in the setting chamber with wind-force and the high control of tube.
The utility model has adopted the novel structure that is different from various previous model fully, and its principle of work is as follows: 1. air classification
In broken sample carried out, the part that reaches the regulation grade was drawn out of at any time and falls to other chamber, had avoided the retardation of frangible gangue ultra-fine grinding pelitization to the goldc grains fragmentation.
Difficult broken rusty gold will be stayed crushing chamber always, and the continuous mill that is subjected to the longer time is carved, and until reaching the particle diameter that wind-force can be discharged, has eliminated the shortcoming to rusty gold selective crushing.
The particle diameter of air classification reduces along with the increase of mineral density, thereby has also eliminated because the density of gold causes the big shortcoming of the granularity error that sieves greatly.
2. continuous sample introduction
The continous way sample introduction has replenished the coarse fraction hard gangue of the mill gold of relying at any time, makes the rusty gold in the sample be in prepreerence mill state at quarter always, makes scrap efficient that breakthrough raising be arranged.
3. powerful continous way mill is carved and is pulverized
Air classification and continuous sample introduction have been eliminated the too fast influence of blocking with pelitization of abrasive material forfeiture, have created precondition for the broken sample of gold mine adopts powerful structure of grinding quarter continuously.The utility model has adopted the brute force mill of reface piece and limits synchronization rolling to carve structure, and it is doubly a lot of that scrap and broken sample efficient have been improved.So just can without in broken, mixing and division, once directly will all directly be finely ground to and analyze the sample granularity requirements through the full-page proof after the coarse crushing, simplified flow process, broken reduction error in having eliminated.Sample quality and work efficiency have been improved.
Therefore, the utility model has good mill gold characteristic, the quick ultra-fine grinding of the rusty gold in the sample can have been solved the sample preparation difficulty that contains the golden sample of difficult processing survey such as coarse gold grain geology sample, the little golden dispersion train of geochemical exploration more up hill and dale, makes the sample good evenness.This machine also can be used for the preparation of other rock forming mineral samples.
The pulverizing machine that the continuous sample introduction air classification is arranged on commercial production is as Suspension roller comminutor, high thin air separation disintegrator etc.Its work characteristics is the continuous feed discharge, paddle type mill roll extrusion fragmentation, and the fan blower air classification, whirlwind is received powder, and sack cleaner is collected and is discharged surplus powder in the wind, and its crushing efficiency is very high.Be used for breadboard sample comminutor but no matter there is no at home and abroad.This be since it exist add many, the inhomogeneous losses of stevedore's damage sample, cleaning is difficult and different samples pollute mutually etc. that these are harmless but to the unallowable shortcoming of the broken sample in laboratory to commercial production.
Fig. 1 has described a practical example of the present utility model.
Fig. 1 is the utility model structural representation.It comprises eccentric block ［ 1 ］, broken specimen chamber ［ 2 ］, abrading block ［ 3 ］, feeder hopper ［ 4 ］, cylinder ［ 5 ］, flexible pipe ［ 6 ］, discharge gate ［ 7 ］, setting chamber ［ 8 ］ and interior pipe ［ 9 ］.
Sample is in broken specimen chamber ［ 2 ］, rotation by eccentric block ［ 1 ］ makes the abrading block ［ 3 ］ in the broken specimen chamber do strong mill motion at quarter, sample is ground, the air movement that utilizes running to form makes the sample dust from flying, the sample that has wherein reached certain levigate granularity can rise by cylinder ［ 5 ］ and flexible pipe ［ 6 ］ and cross interior pipe ［ 9 ］ and enter setting chamber ［ 8 ］ and drop to the bottom, and the sample that granularity the is not enough crushing chamber ［ 2 ］ that then falls back again continues grinding.Treat all to have ground, interior pipe ［ 9 ］ is mentioned, the crushing chamber that falls back of the sample in the setting chamber ［ 8 ］ is added a cover running 1～2 minute, can obtain the sample that uniformity coefficient is satisfied with.If with the machine of broken full-page proof, then pass through sealing sampling device continuous sample introduction from feeder hopper ［ 4 ］.Setting chamber ［ 8 ］ is made funneling, and sample is emitted from discharge gate ［ 7 ］.
The sample preparation course of work of the present utility model is:
Sample is added broken specimen chamber ［ 2 ］, and start running is treated all levigately, and interior pipe ［ 9 ］ is mentioned, and sample is swept back crushing chamber, adds a cover to rerun and can take out in 1～2 minute.If operate the machine of broken full-page proof, from continuously application of sample fragmentation of feeder hopper ［ 4 ］, treat all levigately sample, sample is emitted from discharge gate ［ 7 ］, mix through vortex mixer and get final product.If processing contains the full-page proof of coarse gold grain, treat reinforced finishing, adding the quartz be equivalent to example weight 0.5～1.0% or silit etc. does not more influence the abrasive material of test composition, and gold in the sample decline mill of being delayed time is fully carved, and guarantees all ultra-fine grindings of gold in the sample.
