800L Explosion-Proof Vacuum Planetary Mixer

Product Description

Precision Mixing for High-Risk, High-Performance Formulations


Designed for processing energetic materials, resins, and reactive liquid-solid mixtures in demanding industrial environments. Every component — from the mirror-polished SS316L bowl to the ATEX-certified drive system — is engineered for process integrity, operator safety, and long-term reliability.




Trusted by aerospace and defense manufacturers across Europe.


01. Heavy-Duty Planetary Mixing

Dual SS316L multi-layer mixing blades provide planetary movement for thorough processing of viscous materials. Independent speed adjustment allows flexible operation.

02. High-Speed Dispersion System

Equipped with a 45kW explosion-proof dispersing drive and two SS316L sawtooth dispersion discs for additional high-speed processing.

03. Vacuum Processing

A sealed mixing vessel, explosion-proof vacuum pump and buffer tank form an integrated vacuum system. Designed for processing under reduced pressure.

04. Jacketed Temperature Control

The 2-bar pressure-rated jacket supports heating or cooling through an external thermal medium. Separate temperature sensors monitor the material and jacket temperatures.

05. Hydraulic Discharge Press

A separate hydraulic pressing system with a 316L stainless steel pressing plate helps discharge high-viscosity materials from the mixing vessel.

06. Explosion-Proof Control System

Independent frequency control, Schneider electrical components, Siemens Beide motors and multiple safety interlocks are incorporated into the control system.

Explosion-Proof Safety System

Safety Interlocks for Hazardous Processing:

The machine incorporates multiple mechanical and electrical interlocks to reduce operating risks during lifting, mixing and vacuum processing.

FAQ

Is this planetary mixer explosion-proof?

Yes. This configuration uses explosion-proof components for the mixing drive, vacuum system and electrical control system. The exact explosion-proof specification should be matched to the customer's hazardous-area classification.

What material are the product-contact parts made from?

Can the mixer work under vacuum?

Can the mixer heat the material?

Can Karvil customize the mixer for hazardous materials?
