Galloni EB20/30 Vacuum Investment Mixer

Application

The Galloni EB20/30 is the flagship high-capacity model in Galloni’s line of heavy-duty investment mixers. Engineered for large-scale jewelry factories and industrial casting centers, it is designed to process up to 30kg of investment compound in a single cycle. This powerhouse allows for the simultaneous vacuum-filling of 6 to 8 large flasks (up to 200mm diameter), making it the ultimate solution for high-volume production lines where maximum efficiency and flawless surface quality are required.

Advantages

The EB20/30 features an advanced integrated sieve station, ensuring that investment powder is introduced to the water only after a vacuum has been established. By feeding the powder gradually under vacuum, the system requires less water to reach the target viscosity, resulting in a significantly denser and higher-quality plaster. This process makes air inclusions and surface bubbles impossible, providing a level of contour sharpness and surface smoothness that is essential for premium jewelry and industrial components.

Workshop Suitability

Built for continuous industrial operation, the EB20/30 is equipped with a maintenance-free 2.1kW three-phase motor. Its two-speed gearbox allows operators to easily switch between a high-speed mixing phase and a controlled, precise filling phase. The entire machine is constructed from stainless steel and high-grade aluminum to resist corrosion, while the filling taps are made from a specialized alloy that is unaffected by the abrasive nature of gypsum and water.

Technological Recommendation

With a 30kg mixing volume, the mechanical integrity of the mold is paramount, especially when casting large trees or high-detail resin models. The high-density plaster produced by the EB20/30 offers superior resistance to thermal stress. To protect your investment, the machine includes an integrated filter system that traps fine dust, substantially increasing the lifecycle of the external vacuum pump.

Maintenance / Service

The EB20/30 is designed for longevity and minimal wear. The drive motor and stirring element remain connected throughout the process, preventing mechanical malfunctions during loading. 3DFantom provides full technical support, industrial installation, and a steady supply of original gaskets and replacement filter sets to ensure uninterrupted production.
