Abstract
The utility model discloses a vacuum ball mill. A rotating shaft on one side of the vacuum ball mill is a hollow tube-shaped shaft. One end of the hollow tube-shaped shaft is communicated with the inner portion of the vacuum ball mill, and the other end of the hollow tube-shaped shaft is externally connected with a vacuum pump. A sealed bearing is arranged on the joint between the other end of the hollow tube-shape shaft and the vacuum pump. According to the vacuum ball mill, aluminum powder spreading and milling polishing in a vacuum environment can be achieved, and thus oxidation and nigrescence of the surface of aluminum-silver seriflux are obviously slowed down, whiteness and brightness of the aluminum-silver seriflux are improved and production quality is improved.
Description
Technical field
The utility model relates to the ball mill field, specifically a kind of vacuum sphere grinding machine for aluminum paste production.
Background technology
Aluminum paste is a kind of widely used metallic pigments.The manufacture method of existing common aluminum paste is normally mixed aluminium powder by a certain percentage with petroleum solvent, lubricant etc. under nature and is placed on grinding in ball grinder, again through sieve, press filtration, make filter cake, after the kneading surface treatment, become aluminum paste.The aluminum paste made from this kind method is because the working environment of ball mill inside is in the high temperature aerobic state, cause the obfuscation of aluminum paste surface oxidation, brightness and whiteness are relatively poor, and because the difference of ball mill internal environment shakiness between causing batch is excessive, the particle diameter skewness.
The utility model content
In order to reduce in the mill processes oxygen content in the ball mill, avoid the obfuscation of aluminium powder surface oxidation, improve brightness and the whiteness of aluminum paste, the utility model provides a kind of vacuum sphere grinding machine.
The technical solution of the utility model is as follows:
A kind of vacuum sphere grinding machine, it is characterized in that: the rotating shaft of ball mill one side is the hollow tubular axle, one end of described hollow tubular axle is connected with the inside of ball mill, the external vavuum pump of the other end of hollow tubular axle, and with the junction of vavuum pump sealed bearing is installed.
Described vacuum sphere grinding machine is characterized in that: be separately installed with bearing in the rotating shaft of described ball mill both sides.
Described vacuum sphere grinding machine is characterized in that: the external diameter of described hollow tubular axle is Φ 150mm, and internal diameter is Φ 100mm.
Described vacuum sphere grinding machine is characterized in that: the internal diameter Φ 150mm of described sealed bearing, external diameter Φ 200mm.
Described vacuum sphere grinding machine is characterized in that: described vavuum pump is the twin-stage rotary vane mechanical pump, its speed of exhaust 7.2L/s, limiting pressure 4 * 10
-2Pa.
Described vacuum sphere grinding machine is characterized in that: in the described ball mill ball-milling medium is arranged.
The beneficial effects of the utility model:
The utility model can be realized the aluminium powder polishing that launches and mill in vacuum environment, thereby has significantly slowed down aluminum paste surface oxidation blackout phenomenon, has improved whiteness and the brightness of aluminum paste, thereby has improved product quality.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, a kind of vacuum sphere grinding machine, the rotating shaft of ball mill 2 one sides is hollow tubular axle 4, an end of hollow tubular axle 4 is connected with the inside of ball mill 2, the external vavuum pump of the other end of hollow tubular axle 4, and with the junction of vavuum pump sealed bearing 5 is installed.
Wherein, be separately installed with bearing 1 in the rotating shaft of ball mill 2 both sides; The external diameter of hollow tubular axle 4 is Φ 150mm, and internal diameter is Φ 100mm; The internal diameter Φ 150mm of sealed bearing 5, external diameter Φ 200mm; Vavuum pump is the twin-stage rotary vane mechanical pump, its speed of exhaust 7.2L/s, limiting pressure 4 * 10
-2Pa; Ball-milling medium 3 is arranged in the ball mill 2.
Embodiment 1: the aluminium powder 80kg of D50=13 is joined in the ball mill, add again S150 solvent naphtha 150kg, lubricant 2kg, adopting the vacuum unit is vacuum state with the ball mill inter-process, in grinding, utilize constant temperature cooling unit control grinding temperature to be in steady state, with high-carbon steel ball grinding 30 hours, through screening, press filtration and kneading, obtain the constant-temperature vacuum aluminum paste.According to said method produce continuously three batches.Itself and common aluminum paste are the contrast experiment, can find that △ L value is obviously higher, the difference between batch is obviously very little.Concrete data are referring to table 1.
