Vacuum hopper loader for automatic feeding of powders and pellets
Optimize your material handling with seamless automatic feeding of powders and pellets—ideal for maintaining efficiency in diverse processes, from extrusion to storage, ensuring consistent material flow throughout your production line.

Feeds and Conveys Powders and Pellets
The SFG Vacuum Hopper Loader from Zeppelin Systems is designed to enhance your production efficiency by automating the feeding and conveying of powders and pellets to extruders, processing machines, and storage silos. It features a high-performance bag filter with compressed-air cleaning, ensuring minimal contamination and quick product changeovers with its unified filter plate and hoses. With all product-contact components crafted from stainless steel, this loader maintains high material integrity. The electro-pneumatically operated sealing cone and filling-level control at the base allow seamless integration into continuous operations.
Configured for robust automation, the system comes fully pre-piped and pre-wired with a control system and a master control unit capable of operating up to five devices with a single vacuum pump. It handles an operating temperature range of -10 to +80°C and maintains pressure between -0.5 bar to +0.05 bar, making it versatile for various industrial applications. Suitable for ATEX 2014/34/EU Zone 2/22; 1/21; 20 interiors, the loader is ideal for the plastics, rubber, and food industries. Options for special filter materials, aeration nozzles for challenging materials, and a maximum-level indicator enhance its adaptability to specific production needs.
