Unloader for conical bottom silos
Eliminate product flow challenges effortlessly with this hydraulic-driven unloader, ensuring complete extraction from conical bottom silos while maintaining safety and preventing contamination.

Efficiently Extracts and Unloads Silo Contents
The Hydracone from Morillon is a hydraulic unloader specifically designed for handling non-free-flowing materials stored in conical bottom silos. Utilizing an Archimedes screw driven by a hydraulic motor, it sweeps the silo cone for complete material extraction. Ideal for processing powders, fibrous, dry, and wet products, it serves diverse industries such as food, agriculture, and chemicals. The Hydracone system operates effectively in demanding environments, supporting high temperatures up to 150°C and hazardous atmospheres. By maintaining low-speed, high-torque operation, it minimizes energy consumption while reducing the risk of material bridging. Available in stainless steel options (304 or 316L) and using biodegradable lubricants, it offers eco-friendly options for sustainable operations. Maintenance is efficient, even when the silo is full, with all essential components easily accessible and separated from the product to prevent contamination. The system is configured to integrate seamlessly into continuous production lines, ensuring consistency and safety.
