3D mixer in metal powder mixing applications

        Metal powder is widely used in various mechanical equipment, aluminum, instrumentation, medical, anti corrosion facilities and other fields. The metal powder mixing process is also the most common powder mixing process, except for the pressing of a single metal powder without the addition of a lubricant, and the mixing of the other metal powders before pressing is necessary. The most common mixing equipment used for metal powder mixing is a three-dimensional mixer. At the same time, some problems must be considered when mixing the powder.

          First, it must be taken into account that at any stage of mixing, the powder must not fall freely through the air as it always causes segregation of the powder. To this end, the 3D mixer bucket should be done shorter, such as gold and silver double action 3D mixer is the choice of double cone bucket, more suitable for mixing metal powder. This must also be taken into account when using other types of mixers, such as baffle drum mixers.

 

       Second, the application of metal powder mixing additives such as lubricants in the metal powder mixing. The lubricant is usually mixed with a single or multiple elemental metal powder in the form of a fine powder. The amount of lubricant added depends on the shape of the press, and is usually 0.5 - 1% by weight. Complex shapes require more lubricant in order to reduce mold release pressure. Mixing time, the degree of mixing and lubricants on the powder mixture of liquidity and bulk density and other properties have an impact. Most metal powder mixing time is generally 20-40 minutes. The mixing of metal powders and lubricant powders is often carried out in large quantities in metal powder production plants, supplying the customer with so called "premixes". This means that control of the powder properties, such as control of the fluidity and bulk density of the mix, and sometimes even control of the properties such as dimensional changes of the press during sintering. These are the main responsibilities of the powder producer. However, due to the relatively long transport time for supplying the premix, it is generally less common to use premix powders supplied by the powder producer. Instead, the producer directly purchases the companion mixer for powder blending and product compaction.

        3D mixer in the metal powder mixing applications have matured, gold plastic double-action new 3D mixer is to bring more convenience to all metal products industry, its high efficiency, high uniformity, mixed without segregation and other advantages for each Mixed powder, more suitable for all kinds of metal powder mixing.
