Abstract
The utility model discloses ore sorting equipment, which comprises a ball mill and a spiral grading machine, wherein the material feeding end of the ball mill is provided with a feeding device, an ore grading region and a sand return region are arranged in a grading groove of the spiral grading machine, the sand return region is provided with a sand return scraping plate and a mixed material conveying groove, and the mixed material conveying groove is communicated with the feeding device. The equipment can realize the natural flowing of coarse grade materials, a large number of water resources can be saved, the ball mill adopts the feeding device with the simple structure for realizing the feeding, the continuous flow adding type feeding of the ball mill is realized, the ball mill efficiency is improved, and the energy source consumption is reduced. The structure of the equipment is simple, the operation is reliable, and the service life of each component is long, so the maintenance period is prolonged, the equipment operation and production efficiency is improved, and in addition, the production cost is greatly reduced.
Description
Technical field
The utility model relates to ore dressing production equipment technical field, relates in particular to a kind of ore screening installation.
Background technology
In known technology, the elementary sorting of silver ore mineral material is adopted ball mill and spiral classifier to unite to carry out mostly.Ore materials after the preliminary election behind ball mill or rod mill ore grinding, gets into spiral classifier again and carries out classification earlier.In the assorting room, the thin rank material that is obtained by spiral classifier gets into the next stage sorting, and the thick rank material of telling need be regrinded to ball mill under the promotion of spiral in sand return.The mode of screening installation sand return at present is to connect a sand-returning channel in the upper end of grader spiral, and the other end of sand-returning channel is communicated with the ore deposit casing of giving of ball mill.Through the effect of water under high pressure, make thick rank material and a small amount of bushel iron flow to said giving in the casing of ore deposit through sand-returning channel.Then, through the spoon head of a spoon formula ore feeder rotation thick rank material is ladled out the ball mill from giving one spoonful of spoon of ore deposit casing again.In this process, duplex-spiral classifier, sand-returning channel, ball mill give devices wearing and tearing such as ore deposit casing, spoon head, spoon formula ore feeder very fast, especially spoon first as the life-span have only about 20 days, give ore deposit casing, general life-span of sand-returning channel about 1 year.Each spoon head of changing need be shut down 4 hours.The each replacing given ore deposit casing and about 24 hours times spent of sand-returning channel, strengthened spare parts consumption, reduced the available machine time.The operation shock loading once because spoon formula ore feeder whenever rotates a circle causes power such as motor, reductor, running part is damaged, and current of electric is unstable.Therefore, the defective one that exists of this equipment is the spoon head, gives spare part such as ore deposit casing, sand-returning channel and motor, decelerator and power consumption big; The 2nd, Maintenance Downtime is long, and production efficiency is low; The 3rd, use water under high pressure in process of production in a large number, water resources consumption is big, and the sewage disposal workload is big, and brings environmental pollution in various degree; The 4th, the increase that brings production cost by above-mentioned a series of problems.
The utility model content
The purpose of the utility model provide a kind of water resource and energy resource consumption few, production efficiency is high, and simple in structure, the ore screening installation of dependable performance.
For realizing that the technical scheme that above-mentioned purpose adopted is: a kind of ore screening installation; Comprise ball mill and spiral classifier; The feed end of said ball mill is provided with dispenser; Mineral aggregate graded region and sand return district are set, the mixing feeding groove that said sand return district is provided with the sand return scraper plate and is communicated with said dispenser in the log washer of said spiral classifier.
Said mixing feeding groove is obliquely installed.
Said sand return scraper plate and the coaxial setting of the spiral of said spiral classifier.
Said spiral classifier is a duplex-spiral classifier.
The ore screening installation of the utility model, its beneficial effect is:
1) through sand return scraper plate and the setting that mixes feeding groove, makes the conveying of thick rank material need not the water under high pressure feeding, can realize flowing naturally of thick rank material, practice thrift great amount of water resources thus;
2) ball mill adopts dispenser feed simple in structure, has realized that the Continuous Flow of ball mill adds the formula feed, is beneficial to the raising grinding efficiency, saves energy resource consumption;
3) compared with prior art, this device structure is simple, and is reliable, each member long service life, thus prolonged maintenance cycle, improved equipment operation and production efficiency, simultaneously production cost is reduced significantly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1: the ore screening installation of the utility model, comprise ball mill 8 and spiral classifier, ball mill 8 is installed with the spiral classifier parallel oblique.The feed end of said ball mill 8 is connected with dispenser 7, and this dispenser 7 rotates with the housing of ball mill 8, and through its rotation the sand return material is continuously fallen into to carry out ball milling in the said housing.Said spiral classifier has a log washer 1, is provided with 1～2 spiral classifier 2 in the log washer 1, realizes the classification of mineral material through the rotation of spiral classifier 2.Mineral aggregate graded region 3 and sand return district 6 are set in the said log washer 1, and said sand return district 6 is provided with sand return scraper plate 4, sand return scraper plate 4 and said spiral classifier 2 coaxial settings, and rotate synchronously with spiral classifier 2.In said sand return district 6, be provided with and mix feeding groove 5, this mixing feeding groove 5 is obliquely installed, and is communicated with said dispenser 7, and said sand return scraper plate 4 is positioned at said mixing feeding groove 5.Said spiral classifier is a duplex-spiral classifier.
Operation principle: the ore screening installation of the utility model is in running, and along with the rotation of said spiral classifier 2, thick rank material constantly gets into sand return district 6 by said mineral aggregate graded region 3, and gets in the mixing feeding groove 5.This moment is by the rotation of sand return scraper plate 4; Thick rank material is stirred, advances; On the one hand thick rank material is mixed with water, thereby strengthened the flowability of thick rank material, thick on the other hand rank material constantly flows under the stirring of sand return scraper plate 4 in the said dispenser 7.Because dispenser 7 is communicated with the charging aperture of the housing of ball mill 8, and one is tilting, and in its rotary course, dispenser 7 interior thick rank materials continuously fall in the housing of ball mill 8 and carry out ball milling once more.Material behind the ball milling carries out classification by the said mineral aggregate graded region 3 of feeding pipe 9 entering of ball mill 8 low sides.
The figure of above-mentioned expression, explanation are merely the preferred embodiment of the utility model, are not the restriction to the utility model protection domain, all equivalent variations or modifications of being done according to the utility model claim, and the claim that is the utility model contains.
