This customized 50L Explosion-Proof Vacuum Double Planetary Mixer is specially engineered for mixing highly viscous, resin-like materials up to 3 Pa/s (similar to modeling clay/playdough). Successfully deployed for solid rocket motor propellant production, it guarantees 100% dead-corner-free mixing, zero-bubble vacuum defoaming, and top-tier explosion-proof safety standards. Equipped with an integrated hydraulic discharge press for seamless material handling.
⚡ Ultra-High Viscosity Handling : Features dual multi-layer paddle agitators (5-50rpm) and dual high-speed sawtooth dispersion disks (0-1500rpm), efficiently tearing and kneading materials with extreme dynamic viscosity (0.33 cm*s/g).
️ Comprehensive Explosion-Proof System : Equipped with Ex-proof mixing/dispersion motors (Siemens), Ex-proof electrical control cabinet, Ex-proof vacuum pump, and Ex-proof sight glass lighting to ensure absolute safety in hazardous chemical and propellant manufacturing.
Integrated Hydraulic Discharge : The base is seamlessly integrated with a hydraulic press (extruder), solving the pain point of discharging highly sticky, playdough-like materials.
️ Precision Vacuum & Heating : Retains a 2-bar pressure heating jacket. The specialized vacuum system (-0.09Mpa) includes a unique buffer tank to prevent pump oil backflow, ensuring absolute purity of the propellant.
Smart Safety Interlocks : Advanced Fuling inverter and Schneider electrical components provide overload, overcurrent, and leakage protection. Mixing head cannot rise unless vacuum is released, and low-speed mixing can operate during lowering for optimized operation.
Dual-Twist Blades + Dual-Dispersers: Designed for High Viscosity.
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.
