Abstract
The utility model discloses a low-noise ball mill comprising a rotary drum, a rotary support seat, a discharge port, a base and a feed inlet; the rotary drum is arranged on the base through the rotary support seat; the discharge port and the feed inlet are connected with the rotary drum through flanges; the rotary drum comprises a drum body, a sound-absorbing material and a drum body liner, and the inner cavity of the rotary drum is divided into a first milling bin, a second milling bin and a third milling bin; a first screen is arranged between the first milling bin and the second milling bin, a second screen is arranged between the second milling bin and the third milling bin, and a third screen is arranged between the third milling bin and the discharge port; and an Alpha-degree angle is formed between the rotary drum and the horizontal plane. According to the low-noise ball mill, the three milling bins are arranged, so the granularity of powder material can be effectively improved; the sound-absorbing material arranged between the drum body and the drum body liner can effectively reduce the noise generated in the milling process of the ball mill; and as the Alpha-degree angle is formed between the rotary drum and the horizontal plane, the milled finer powder material can rapidly enter a next milling bin.
Description
Technical field
The utility model relates to the milling device of nano material in the chemical field, relates in particular to a kind of low noise ball mill.
Background technology
Ball mill is the cylindrical shell by level, input and output material hollow shaft and bistrique etc. partly form, cylindrical shell is long cylinder, in the cylinder abrasive body is housed, cylindrical shell is the steel plate manufacturing, has steel liner plate and cylindrical shell to fix, and abrasive body is generally the steel ball, and pack in the cylinder by different-diameter and certain proportion, abrasive body is available steel section also.Granularity according to grinding material is selected, material has feeding of ball mill end hollow shaft to pack in the cylindrical shell, when ball mill barrel rotates, abrasive body is because inertia and centrifugal action, the effect of frictional force is attached on the shell liner its note and is taken away by cylindrical shell, when being brought to certain height, left owing to the Action of Gravity Field of itself, the abrasive body of whereabouts is smashed the material in the cylindrical shell as the projectile.
Ball mill common in the prior art is for being horizontally disposed with, and material is mainly pushed ahead by the rotation of cylindrical shell, so that production efficiency is low, and the milling body in the ball mill barrel and the material noise that the meeting generation is very large in mill processes.
The utility model content
For the deficiency of above-mentioned existence, the utility model provides the low noise that a kind of production efficiency is high, noise is low ball mill.
In order to reach the foregoing invention purpose, the technical solution adopted in the utility model comprises cylinder, rotary support seat, discharging opening, base and charging aperture for a kind of low noise ball mill is provided; Described cylinder is arranged on the base by rotary support seat; Described discharging opening is connected flange and is connected with cylinder with charging aperture; It is characterized in that: described cylinder comprises cylindrical shell, sound-absorbing material and cylinder lining, and described sound-absorbing material arranges between cylindrical shell and the cylinder lining; The inner chamber of cylinder is divided into first three storehouses of milling, storehouse of milling, storehouse and the 3rd of milling, storehouse, second of milling; Milling and be provided with the first screen cloth between the storehouse in described first storehouse and second of milling, mills and be provided with the second screen cloth between the storehouse in second storehouse and the 3rd of milling, and the 3rd mills is provided with the 3rd screen cloth between storehouse and the discharging opening; Described cylinder is horizontal by α degree angle.
Preferably, the α degree angle between described cylinder and the horizontal plane is arranged in 10 ° ~ 30 ° scopes.
Preferably, the order number of described the first screen cloth is less than the order number of the second screen cloth; The order number of the second screen cloth is less than the order number of the 3rd screen cloth.
The beneficial effects of the utility model are:
1, three of this low noise ball mill barrel inner chamber setting storehouses of milling can be improved the dusty material granularity effectively.
2, the sound-absorbing material that arranges between cylindrical shell and the cylinder lining can reduce the noise that ball mill produces between the friction of milling body and material effectively in mill processes.
3, the α degree angle that arranges between cylinder and the horizontal plane is so that the thinner dusty material of milling enters the next one storehouse of milling fast.
Description of drawings
