Indoor Storage System

Slewing screw type silo storage system

This system is highly suitable for handling materials with poor fluidity in medium-sized silos. It is widely used particularly in biomass power generation projects where wood chips and such like are used.


This storage/discharge system is used to store materials with relatively poor fluidity in medium-sized silos. By rotating the screw that extends from the center of the silo, the materials handled are moved to the center and discharged from the chute at the foot to the lower conveyor. In recent years, the system has been widely used particularly in biomass power generation projects.

Applications Storage of materials with relatively poor fluidity Materials handled Wood chips, rubble, RPF, wood pellets, etc.
Deliveries 14 cases (domestic power plants, paper manufactures, etc.) Capacity Silo capacity: 1,300 to 13,000m³ (260 to 5,120t)
Discharge capacity: 9 to 880m³/h (1.8 to 320t/h)


Feature 01Highly user-friendly maintenance

The system is easy to maintain due to its simple structure. Maintenance is possible even when there are items in the silo since the drive unit is located below the silo.

Feature 02Good compatibility with materials with poor fluidity

It is highly suitable for storing wood chips and other materials with poor fluidity that are difficult to handle by other methods. The combination of a straight body silo and a powerful scooping mechanism with screws eliminates any concern about blockage in bridges and enables stable storage and discharge.

Feature 03Simplified silo structure

It has a simple structure with excellent storage efficiency even among our storage systems, and helps to reduce overall costs of the silo including the foundation.

  • First-in, first-out operation avoids congestion and is less prone to spontaneous combustion
  • Eco structure that offers excellent airtightness and prevents scattering of dust
  • Construction of automatic operation system contributing to labor saving
  • Proposing the optimum silo system based on materials handled and storage capacity
