Flouring technology it is also more and more, powder manufacturing apparatus is varied, and milling efficiency is also higher and higher.
Fine Aluminum Powder has wide range of applications, but different industries are different to the granularity requirements of Fine Aluminum Powder, and existing aluminium powder is raw
It produces the Fine Aluminum Powder that enterprise produces to need to be classified by classifying equipoment, the Fine Aluminum Powder of different grain size range packs deposit respectively
Storage, packing and selling after then needing again to mix the Fine Aluminum Powder of different grain size range according to client, mixes to Fine Aluminum Powder
When, the most commonly used is blenders, the Fine Aluminum Powder of required different grain size range are added in the mixing tank 2 of blender, then
Mixing tank 2 is rotated, realizes the mixing of the Fine Aluminum Powder of different grain size range.Existing blender volume is big, and mixing tank 2 revolves together
Turn, the required big energy consumption of power is high, and mixed Fine Aluminum Powder size distribution is uneven.
In addition, in mixing, aluminium powder is added directly into mixing tank 2, lacks corresponding inertia for aluminium powder manufacturing enterprise at present
The protection of gas, Fine Aluminum Powder is easy to oxidize in mixing process, forms oxide layer on aluminum particle surface, it is pure to influence aluminium powder
Degree, and aluminum particle inevitably collides friction in mixing process, the raising of aluminium powder temperature, and aluminium belongs to molecular proportion
More active metal, exposure easily aoxidize in air, are also easy to happen the perils such as explosion, aluminium powder temperature in mixing process
It increases, and lacks the protection of inert gas, there are explosion dangers.
