Double Planetary Mixer for High Viscosity Graphite and Solvents

Designed for high-viscosity and flammable materials, this 30L Explosion-Proof Vacuum Planetary Mixer integrates mixing, dispersing, and wall-scraping. Equipped with a 3kW electric heating jacket, -0.09Mpa vacuum system, and full EX-proof components, it ensures safe and bubble-free processing for epoxy resins, solvent-based coatings, graphite, and ferrite pastes. Includes an integrated hydraulic discharge press.


Core Features

  • Complete Explosion-Proof System : Ensure maximum safety when handling volatile solvents. Features EX-proof motors (Siemens), EX-proof 3kW heater, EX-proof sight glass light, and a dedicated EX-proof control cabinet.

  • Dual-Shaft High-Efficiency Mixing : Combines a low-speed twist/spiral blade (5-50rpm) and a high-speed toothed dispersing disc (0-1500rpm). Ideal for complex solid-liquid dispersion without dead zones.

  • Vacuum & Heating Integrated : Built-in -0.09Mpa vacuum capability with a buffer tank prevents oil backflow. The jacketed vessel supports electric heating with precise PT100 temperature monitoring.

  • Premium Material & Hygienic Design : All contact parts are made of SS304 stainless steel with internal/external mirror polishing. The PTFE scraper ensures no material residue on the inner walls.

  • Smart Safety Interlocks : Advanced safety features including emergency stop, vacuum-lift interlock (cannot lift when under vacuum), and inverter overload/leakage protection.

1.Manufacturer or trading company?

We are a professional manufacturer with over 20 years of experience, specializing in Sigma Mixers, Ribbon Blenders, and Planetary Mixers. Unlike trading companies, we have our own R&D team and strict quality control system, which allows us to offer direct factory prices and technical support.

2.What is the main market for your company?

Our machines have been exported to over 50 countries, including markets in Europe, America,Australia and Southeast Asia. We serve industries ranging from chemicals, energetic materials, adhesives, and sealants to food and pharmaceuticals.

3.How do you ensure the quality of the machine before delivery?

Quality is our priority. After production, we conduct a strict FAT (Factory Acceptance Test). We run the machine empty and with load (if applicable) for continuous hours to check noise, vibration, sealing, and temperature. We will send you a detailed running video. You are also welcome to visit or hire a third party (like SGS/BV) for inspection.

4.Can I track the production progress of my order?

Yes. During the production process, our sales team will update you with photos and videos of key stages (machining, welding, assembly, painting) so you can know exactly the status of your equipment.

5.How about the installation and services?

We provide comprehensive support:

Documents: Detailed English manual, electric diagram.

Online Support: Lifetime remote video guidance for installation and troubleshooting.

On-site Service: If needed, we can dispatch engineers to your factory for installation, commissioning, and staff training.

6.How do you pack the machine to ensure safety during long shipping?

We use export-standard plywood cases ensuring stability. For the machine surface, we wrap it with multiple layers of stretch film to prevent moisture and corrosion during sea transportation.

7.Can you provide customized products?

Yes, we have professional engineers to meet your special design needs, so we can provide customized products.

8. What are the payment terms and delivery time?

Production begins after confirming details and receiving a 50% deposit. It usually takes 20-30 days. Once you approve the machine via test videos or on-site inspection, we will arrange shipment immediately after the balance payment.

9.About the product warranty?

We provide 12-month warranty starting. Within the warranty period, we provide free replacement parts with DHL/Fedex . Beyond the warranty, we offer cost-price spare parts and lifetime technical support.


Superior High-Viscosity and High-Solids Handling

Karvil mixers are engineered specifically for the most challenging mixing tasks in modern industrial processes:

Ultra-High Viscosity Capability: The mixers are designed to handle materials with viscosities ranging from 10,000 cPs up to 1,000,000 cPs, with special customized models reaching even higher (up to 5,000,000 cPs). This is crucial for products like battery pastes, high-density sealants, and specialty chemical compounds.
Zero Dead Zones & High Homogeneity: The double planetary movement ensures that the mixing paddles both rotate on their own axis and revolve around the tank's center. This complex motion thoroughly processes all material in the vessel, eliminating dead zones and achieving rapid, superior uniformity.

Advanced Process Control and Multi-Functionality

Karvil positions its equipment as a comprehensive processing platform, not just a mixer:

Integrated Vacuum Degassing: The reliable airtight tank and powerful vacuum system efficiently remove air and moisture trapped in high-viscosity pastes. This is essential for preventing defects in final products like electronic materials, optical adhesives, and sealants, guaranteeing high density and stability.
Precision Temperature Control (Heating & Cooling): The jacketed design allows for precise thermal management via electric heating, steam, or circulating fluid. This enables tight control over complex, temperature-sensitive processes (e.g., polymer reactions or high-solids dispersion).

Optimized Structure for Efficiency and Reliability

The design focuses on improving manufacturing workflow and long-term durability:

 

  • Hydraulic Operation and Easy Cleaning: The hydraulic lifting system facilitates easy access for maintenance, cleaning, and rapid exchange of mixing tanks (Changeable Inner Tank design). This drastically reduces downtime and prevents cross-contamination between batches.

  • High Precision Assembly: Karvil emphasizes high-tolerance manufacturing (core parts precision often less than 30 $\mu\text{m}$) to ensure stable running, low vibration, and quiet operation, extending the equipment's lifespan and reliability.
