Working Principle
The machine is mainly composed of mixing barrel, frame, transmission system, electrical system and other parts. It uses two asymmetric drums and uses gravity mixing. The materials are continuously gathered and dispersed in the barrel. It is especially suitable for the specific gravity and suspension of two or more materials. The mixing uniformity is more than 99%. The stainless-steel butterfly valve is used to discharge materials without leakage and dust flying. This machine has unique design, beautiful appearance and wide application. It is an ideal equipment for mixing materials.
Applicable Materials
Powders or particles whose specific gravity is up to 7g/cm³ and with certain fluidity, liquid content is under 10%, such as medical intermediate, flavoring, flour, essence, graphite, coffee powder, iron powder, etc.

Why Choose POLYC Gravity Mixers?
Optimal Asymmetric Geometry
The intentional offsets in our asymmetrical double-drum structure completely eliminate dead mixing zones, guaranteeing homogeneous dispersion under 10 minutes.
Heavy Particle Adaptability
Reinforced bearing housings and heavy-duty electric motors allow our mixers to reliably agitate materials up to 7g/cm³ specific density like graphite or iron dust.
Hermetic Sanitary Integrity
Utilizing high-finish food-grade stainless steel butterfly valves ensures absolute sealing, avoiding powder leakage, workspace dust suspension, or external contaminants.

Frequently Asked Questions
What is a gravity powder mixer used for?
A gravity powder mixer (like the PYXM series) is designed to blend dry, free-flowing powders or granules of varying particle sizes and specific gravities. It is widely used in pharmaceuticals, food processing, chemicals, plastics, and metallurgy.
How does the PYXM achieve 99% mixing uniformity?
The mixer features an asymmetric dual-drum geometry. As the vessel rotates, gravity forces the material inside to continuously separate, slide, gather, and disperse. This natural multi-directional flow ensures highly consistent blending without shear damage.
What is the maximum specific gravity of materials the PYXM can handle?
The heavy-duty design of the PYXM series can successfully process materials with a high specific gravity of up to 7 g/cm³, making it ideal for dense metal powders, minerals, and heavy chemical compounds.
How is the mixed material discharged?
It is discharged from the bottom using a high-precision, food-grade stainless steel butterfly valve. This ensures a hermetic, dust-free seal during operations and zero leakage during discharge.
What determines the actual mixing time for my material?
While the standard mixing cycle is roughly 6 to 10 minutes, the precise duration depends on material properties such as particle size, density variation, moisture content (which must be under 10%), and overall batch volume.
What is the warranty on the PYXM mixer?
Every POLYC PYXM mixer comes with an industry-standard 1-year comprehensive manufacturer's warranty, covering critical transmission systems and structures, alongside lifetime expert technical assistance.
