Mixing impeller is also called agitator blades.The Mixing impeller types are many. Generally speaking, the Mixer impeller is divided into two categories: for low viscosity liquids and for highly viscous liquids.
Paddle, curved blade turbine, hinged turbine, disc turbine, push, Bruma gold and toothed plates are suitable for agitation of low viscosity liquids. In the turbulent state, the ratio d/D of the impeller diameter d to the groove inner diameter D is usually about 0.3 to 0.6.
Anchor, ribbon and screw are suitable for agitation of highly viscous liquids. Operates in a laminar or transitional flow state. In the case of mixing a highly viscous liquid, in order to reduce the poorly mixed retention zone, the d/D is usually about 0.9. The exception is the screw impeller, which is either offset or used with the draft tube. The d/D is typically 0.4 to 0.5.
In terms of materials, stainless steel casting impellers are our superior products.
Stainless Steel Casting for Mixing Impeller
Stainless steel are widely used as the material of mixing impeller. Because Stainless Steel Casting has excellent advantages of resistance to corrosion.It can minimize contamination of the materials being processed.Especially the surfaces that contact the fluids. Such as in the food, dairy, beverage and pharmaceutical industries. Its demand is from the smooth surfaces.So stainless steel casting will be the best choice
Mixing Impeller Casing Process
From the types of mixing impellers, there are many different shapes with different structure. That cause the producing method will be different.To meet the multi demands of mixing impellers, our foundry use stainless steel lost wax casting method, also called stainless steel investment casting,to manufacture mixing impellers.After the wax in shell is melted,we poure the liquid metal into shell.After cooling, the impeller was made.With investment casting, mixing impeller has good surface finish.It reduce or save secondary machining to save time and cost.
To obtain a shining or more surface effect, we usually make the post treatment.On the surface of stainless steel casting mixing impellers, we can make either mechanical or chemical treatments or by electropolishing. Surface scale and discoloration that appears after heat treatments can be removed by chemical treatments. For high purity requirements electropolishing not only offers the advantage of being versatile, but provides a very smooth surface that is readily passivated.
Stainless Steel Mixing Impeller Casing supplier
As the professional and leading stainless steel casting manufacturer in China.Customizing casting is our most advantages.Our company is able to to customize mixing impeller as per our client’s sample or drawing. On materials choice,we often cast mixing impeller with 316L stainless steel or even higher stainless steel grade, then passivated, electropolished or mirror polished.
