Solid Fuel Vertical Kneader | Explosion-proof Vertical Kneader Manufacturer

Solid propellants typically consist of a polymer binder, an oxidizer, metal powder, and various additives; they are characterized by:
· Extremely high viscosity
· High solids content
· Sensitive to temperature fluctuations
· Susceptible to friction and static electricity
· Demanding requirements for mixing uniformity
Compared to traditional horizontal kneaders, the vertical configuration allows the drive system to be positioned above the material, preventing the shaft seal from remaining in prolonged contact with high-viscosity material. This structural design mitigates friction-induced heat generation and leakage risks; when combined with vacuum, temperature control, and explosion-proof systems, it is better suited for high-safety-standard mixing processes.

01 Design without bottom shaft seal
All bearings and the gear reducer are located at the top of the equipment.
· Prevents material from entering the shaft seal
· Reduces frictional heat
· Enhances safety
· Facilitates easier maintenance
02 Vacuum degassing
A vacuum level of -0.098MPa can be maintained for extended periods. This effectively removes air from the slurry, enhancing product density and consistency.
