Description

Vertical metal fine pulverizing ball mill

The utility model relates to a kind of raw metal granularity and is crushed to the meticulous crushing ball mill apparatus of 325 purpose vertical metals below 3 millimeters, and it is made up of prime mover, main shaft, water jacket, container, water inlet, support, discharge port plate, valve, delivery port, charge door, blade etc.

The ball mill of existing processing metal explosive powder, fireworks powder, coating powder and slurry is horizontal.Dry pulverization process is arranged, and this method has the possibility of blast, and is dangerous, and produces a large amount of dust in the processing, with the minimizing of this method production; Wet method powder essence is to utilize solvent naphtha to be put in the ball mill, and the shell of ball mill rotates, and the steel ball in the machine is also along with shell rotates, fall downwards when steel ball forwards certain altitude to, raw metal is smashed, owing to be freely falling body when falling under the steel ball, so the noise that produces is big, and efficient is low.

For solve existing horizontal ball mill explosion-proof, noise is big, inefficient problem, and a kind of noise of invention is little, production efficiency is high, and motor is not taked the meticulous crushing ball mill apparatus of vertical metal of any explosion precaution.

The utility model by a prime mover as power, connect the main shaft that blade is housed on prime mover, blade is a garden shape, in its container of packing into, container is the garden tube of a metal, a discharge port plate that has a plurality of holes is adorned in the container bottom center, and a valve is arranged at the discharge port plate bottom, container peripheral equipment one

Individually can reduce the water jacket that is caused increase in temperature by friction, water inlet and delivery port are arranged on the water jacket, charge door of container left upper portion peace is put into the steel ball that diameter does not wait during processing in the container, and the utility model integral installation is on support.

Description of drawings

Accompanying drawing is a general illustration: 1, prime mover 2, main shaft 3, water jacket

4, container 5, water inlet 6, support

7, discharge port plate 8, valve 9, delivery port

10, charge door 11, blade 12, steel ball.

Below in conjunction with accompanying drawing the utility model is elaborated: the utility model by prime mover (1) as power, conversion arbitrarily between its Revolution Per Minute 10～500 changes, the main shaft (2) that it is 50mm that a diameter is adorned in prime mover (1) bottom, it is porose that main shaft (2) is gone up processing, with key blade (11) is installed in the hole of main shaft (2), blade (11) is a garden shape, blade (11) and main shaft (2) place's of passing through diameter mutually are 35mm, two ends are 30mm, its length 350～450mm, each blade installation site misplaces 90 ° mutually, promptly a blade is vertical with another blade, and each blade also is vertical with main shaft (2), and above-mentioned parts are contained in the container (4) of a garden tube, container (4) is all formed by welded steel plate, perhaps adopts casting.Bottom centre position is equipped with a discharge port plate (7) that is processed with a plurality of holes, the pore diameter size of discharge port plate does not spill with the minimum diameter steel ball and is advisable, discharge port plate (7) bottom is a valve (8) control discharging, the container upper left quarter has a charge door (10), friction generates heat owing to add man-hour, too high for preventing temperature, the outside of container (4) is equipped with a water jacket (3), be welded as a whole with container (4), adding the heat that produces man-hour is dissipated by water jacket, water in the water jacket (3) flows, and is added by water inlet (5), is discharged by delivery port (9), preservative treatment is carried out in water jacket (3) inwall and container (4) outside, the steel ball (12) that the diameter of packing in the container (4) does not wait, wherein: diameter 4mm accounts for 40%, diameter 5mm, 6mm, 7mm, 8mm, 9mm, the steel ball of 10mm respectively accounts for 10%.Whole upright dressing is gone up (seeing accompanying drawing) at support (6).Method of operating of the present utility model is: the steel ball of the 10-15 times of feed metal grain weight amount of at first packing into is in container (4), add the aqueous solution or organopolysiloxane oil solvent naphtha, its consumption is 0.8-1.5 times of feed metal grain weight amount, start prime mover (1), stirrer paddle (11) is changeed with per minute 30 transhipments, the raw metal that will be equivalent to 1/10-1/15 steel ball weight again adds in the container (4) slowly, turn round after 1-2 minute, after confirming to mix, change entering the work running again with per minute 300-500.Steel ball ratio big pulverizing time of healing is shorter, at this moment because the rising of friction container (4) temperature, regulate the flow of water in the water jacket (3), with controlling temperature, the high floatability of temperature is poor, and the low polishing effect of temperature is bad, as processing be coated with slip or powder then temperature be controlled at 45 ℃-53 ℃, so running is 5-7 hour, when raw material granularity reaches requirement, mixing speed is reduced to per minute 100-150 change, add the solution identical with original solution, its consumption be original consumption 1/2 with diluted material, add back running 2-3 minute, shut down, open dispensing valve (8), solvent or diluent is emitted and is got final product, and solvent or diluent can be made dry powder or slurry respectively according to the difference of purposes.

The utility model is compared with existing production method, not only raise the efficiency (than wet method) more than three times, and the product granularity of producing is even, do not need special screening operation, noiselessness, no dust, as make the metallic paint powder and then can cancel polishing process with slurry, and safe and reliable.
