Abstract
The utility model relates to a grading device for a dry ball mill, which consists of a driving mechanism, a feeder, a stirring shaft, a ball mill crushing cavity, a grader host machine I , a grader host machine II , a cyclone collector, a bag dust collector, an induced draught fan and an air inlet, wherein the lower end of the feeder is connected with the ball mill crushing cavity; the inner center of the ball mill crushing cavity is provided with the stirring shaft which is connected with the driving mechanism; the upper end of the ball mill crushing cavity is connected into a whole with the grader host machine I ; and the grader host machine I , the grader host machine II , the cyclone collector, the bag duct collector and the induced draught fan are connected with each other in turn through blast pipes. The grading device for the dry ball mill crushes and grades objects in advance by combination of the dry ball mill and an air classifier; micro powder particles which are crushed by the grading device have unique shapes, and are particularly suitable to be grinded and cut; the shape is different from a round taper angle when the micro powder particles are crushed by a jet mill and is also different from the shape of a strip, a plate and a needle when the micro powder particles are crushed by a Raymond mill, and is an equiareal figure with a taper angle, so that the micro powder particles are suitable to be used as special cutting edge materials for cutting a wafer cell slice; and the odd yield is as high as 75 percent.
Description
Affiliated technical field
The utility model relates to a kind of plant equipment, the ball grinder graded equipment of especially a kind of dry type.
Background technology
Existing micro mist disintegrating apparatus has: 1. airflow milling: the output height, and productive rate reaches 75%, the silicon carbide micro-powder particle that fragmentation goes out, equivalance shape is more, accounts for more than 90%, and shape is round, no wedge angle, and particle exists and falls into the property crackle, is unfavorable for cutting.2. Raymond mill: output height, productive rate only 65%, the silicon carbide micro-powder particle that fragmentation goes out, equivalance shape is less, accounts for more than 50%, and needle-like, sheet, irregularly shaped particles is more, and is not wear-resisting.3. wet ball mill: yield poorly, productive rate only 30% is crossed and is pulverized seriously, and particle shape is good, and equivalance shape is many, and wedge angle is arranged.
The ball grinder graded equipment of dry type of the present utility model has solved above defective, adopt dry ball to combine with gas flow sizing machine, object is pulverized and pre-classification, so promptly guaranteed the raising of output, reduced again to cross to pulverize and reduced energy consumption, and the most important is to have overcome above three kinds of equipment deficiencies, micro powder granule shape uniqueness after the pulverizing, be very suitable for grinding and cutting, its grain shape had not both had the circle so of airflow milling pulverizing and had not had wedge angle, was different from the strip sheet after Raymond mill is pulverized yet, needle-like, but equivalance shape has wedge angle, be suitable for the dedicated blade material as the use of cutting crystal wafer battery sheet, and odd numbers output is up to 75%.
Summary of the invention
In order to solve and to overcome the deficiencies in the prior art, the utility model provides a kind of dry type ball grinder graded equipment, and this equipment can improve odd numbers silicon carbide micro-powder output and productive rate changes grain shape, improves the cutting force and the durability of micro powder granule, this technology has big output, the low energy consumption characteristics.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model adopts dry ball to combine with gas flow sizing machine, object is pulverized and pre-classification, constituted by transmission mechanism, feeder, shaft, ball mill crushing chamber, grader main frame I, grader main frame II, cyclone collector, sack cleaner, air-introduced machine, air inlet.The feeder lower end links to each other with the ball mill crushing chamber, the center is a shaft in the ball mill crushing chamber, shaft links to each other with transmission mechanism, ball mill crushing chamber upper end connects as one with grader main frame I, grader main frame I, grader main frame II, revolves gatherer, sack cleaner, air-introduced machine and links to each other by airduct successively.Main motor drives shaft drive mixing arm high-speed motion by belt dressing, forces medium ball and grinding charge material in the mill chamber to do random motion, clashes into mutually between medium ball and the material, shear and friction, thereby realization is to the superfine grinding of material.During work, sic raw material enters in the chamber from charge door, grinds broken back under the air-introduced machine effect, and air-flow enters from air inlet, and with butt to suction, the fine powder body that grinds the zone is blown afloat, send into grader main frame I by cylindrical shell and send.Coarse granule falls in the crusher chamber broken again along barrel.Fine grained enters grader main frame II and carries out sorting once more.At this moment regulate the grader rotating speed, undesirable trickle powder is sent into whirlwind and bagroom collection, and the fine powder of collecting from first order feed opening is needed odd numbers qualified products.
The beneficial effects of the utility model are broken back micro powder granule particle shape uniquenesses, and equivalance shape has wedge angle, and single grain size number is many, the output height; This equipment energy consumption is low, and 1 ton of material ratio airflow milling of every pulverizing is pulverized and saved 1000 degree; Noise is little, and equipment when work noise is less than 60 decibels, and the Raymond mill operating noise reaches 80 decibels.Material after the fragmentation of this kind equipment is compared with Raymond mill, has reduced the oil content in the material, and total amount has reduced 90%.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is that schematic diagram is arranged in technological process of the present utility model.
1. feeders among the figure, 2. shaft, 3. grader main frame I, 4. grader main frame II 5. revolves gatherer, 6. sack cleaner, 7. air-introduced machine, 8. air inlet, 9. ball mill crushing chamber, 10. transmission mechanism
The specific embodiment
Feeder (1) lower end links to each other with ball mill crushing chamber (9), interior center, ball mill crushing chamber (9) is shaft (2), shaft (2) links to each other with transmission mechanism (10), upper end, ball mill crushing chamber (9) connects as one with grader main frame I (3), grader main frame I (3), grader main frame II (4), revolve gatherer (5), sack cleaner (6), air-introduced machine (7) and link to each other by airduct successively, describe with an embodiment below:
1. get the carbonization silica sand after sieving, its particle evenly adds its speed of per hour pressing 70kg in the feeder continuously less than 5mm.
