Powder mixing is an indispensable production process in modern industry, applied in many fields such as materials, food, medicine, fertilizers, metallurgy, etc. There are four main forms of mixing: convective mixing, diffusion mixing, shear mixing, and seepage mixing. There are various types of powder mixing equipment, including horizontal ribbon mixer, horizontal plough mixer, horizontal non-gravity mixer, horizontal drying mixer, nuata mixer, etc., which have the characteristics of high efficiency, high uniformity, low energy consumption, and low pollution.

1. Introduction to Common Powder Mixing Equipment
Powder mixing is an indispensable production process in modern industry, applied
in many fields such as materials, food, medicine, fertilizers, metallurgy, etc. There are
four main forms of mixing: convective mixing, diffusion mixing, shear mixing, and
seepage mixing.
There are various types of powder mixing equipment, including horizontal ribbon
mixer, horizontal plough mixer, horizontal non-gravity mixer, horizontal drying mixer,
nuata mixer, etc., which have the characteristics of high efficiency, high uniformity, low
energy consumption, and low pollution.
Horizontal ribbon mixer consists of drive disk assembly, double layer ribbon
agitator, U-shape cylinder. Inside ribbons move materials toward the ends of the ribbon
blender whereas the outside ribbons move material back toward the center of the ribbon
blender, therefore, materials get fulling mixing. Materials flow direction are determined
by ribbon angle, direction, twining method. Material outlet are located in the middle of
cylinder bottom. Outside ribbon driven by main shaft moves materials to discharging
to ensure no discharging dead zone.

2. The special design of double ribbon mixer the materials into high uniformity in a
few minutes. On the other hand, ribbon mixer shows a wide application from powder
mixing, powder-liquid, to paste or materials in high specific gravity (such as putty,
really stone paint, metal powder and other materials) and becomes one of the most
popular single shaft horizontal mixing equipment.
Horizontal plough mixer is a Germany-technical late-model mixing equipment,
consisting of drive disk assembly, agitator, round-shape cylinder, high-speed fly-cutter.
The agitator consists of multi-group of plough and fly-cutter. The plough not only
disperses materials along axial direction during high speed rotation, but drives the
materials flow in circles around the cylinder wall, which settles the stratification
efficiently.
It is especially for the materials which may get aggregation during mixing. Liquid
can be sprayed into powders. Vacuum system and drying system are also in option.

3. Horizontal non-gravity mixer is a Korean-technical late-model mixing
equipment, consisting of conveying part, blade-type agitator, twin U-shape working
chamber. Agitators, designed in special angle, rotates in same but opposite direction
and shows a nice mixing, smashing, dispersing results. It is also able to used for
materials in different specific gravity and particles in a wide range of sizes.

4. Horizontal drying mixer is a multi-function mixer combines mixing, reaction
and drying, widely used in industries of food, chemical industries, building materials,
lithium battery, etc., during the process of which the liquid needs to be added, and after
mixing the liquid needs to be removed or the liquid content is too high so it needs to
decrease.
The machine is with heating jacket, which can heat the materials by hot water, hot
oil, steam and other medium. The whole machine is designed as closed type, vacuum
system is for option to pump out the air and drain the liquid. In addition, a dust collector,
condensing reflux device, solid-gas separator, etc. will be equipped in front of vacuum
system to reduce the raw materials consumption.
Nuata mixer is one of the earliest developed products and till now, consisting of
driving part, spiral agitator and inverted cone working chamber. There are two
asymmetric spiral shafts, with their self-rotation and revolution, materials are lifted

5. repeatedly to finally realize the purpose of well-mixed.
Efficient mixing technology is the guarantee of obtaining high-quality products.
Reasonable mixing can improve production efficiency and product quality, reduce
waste, and save resources. To achieve a stable and reliable level of mixed production
technology, it is crucial to choose high-performance mixing equipment. In addition, the
selection of auxiliary equipment also needs to be considered in order to achieve the best
results when used in combination.
