Indoor Storage and Discharge Systems

Environmentally Friendly Systems

These systems are used for indoor storage and discharge of raw materials and fuels unloaded from ship to shore. They are also suitable for environmentally conscious storage and discharge of by-products generated at power stations or steel works without outdoor discharging.

Indoor Storage and Discharge Systems Line-up

Large Silo System

This system is for indoor storage and discharge of coal for use as fuel at thermal power stations mainly in Japan without the need for outdoor discharging. We have the top market share for silo systems in Japan. One silo can hold up to 70,000 tons.

RDM (Rotary Discharge Machine) with six discharge arms installed at the silo bottom travels back and forth while rotating to automatically reclaim bulk material at a controlled rate.

Medium-sized Silo System

We provide Indoor Storage and Discharge Systems for waste timber and tire chips used as fuel for biomass power generation, wood chips used at paper mills, limestone from quarries, and oil coke generated at oil refineries.

RRR Type

Screw (RRR Type: Slewing Screw Type) installed at the center of the silo bottom rotates and turns to move the bulk material toward the center and discharge it. This system is suitable for relatively light materials.

RTR Type

Screw (RTR Type: Travelling Screw Type) installed at the bottom of a cone-shaped silo rotates and travels to move the bulk material to the conveyor installed beside the silo. This system is suitable for relatively light materials.

Centrex Type

A uniquely curved discharge arm installed under the silo scrapes the bulk material toward the center to automatically discharge it to the conveyor underneath. This low-cost, easy-to-maintain system has a simple structure.

RRDM Type

RRDM (Rotating Rotary Discharge Machine) discharge wheel with six arms installed at the silo bottom revolves at a controlled rate to smoothly discharge heavy, sticky material with poor flow characteristics, such as FGD-gypsum and clinker.

Small Silo System

This system is for storage of waste building materials, waste timber, RPF, and tire chips mainly used as fuel for biomass power generation.

MD Silo System

Several reciprocating rake feeders installed at the bottom of a rectangular silo move backward and forward by means of hydraulic cylinders to forcefully discharge the material beneath the silo. This system is suitable for material with very poor flow characteristics and bulky material.
