Silo Discharge Machine
Discharge, Distribution, Reclamation and Storage of Bulk Materials
Silo dischargers are employed for materials that have such poor flow characteristics that gravity alone is not sufficient to allow them to flow from a silo, hopper, or tank. This equipment solution prevents typical discharging problems, such as sticking, bridging, and ratholing.
About the Silo Discharge Machine
WTW’s Silo Bin Discharger is our most versatile and flexible discharge system. Available in sizes from 1.5 to 6 meters in diameter and discharge capacities up to 1,000 t/h, WTW’s Silo Discharge Machine is one of our most requested installations.
The task of the central discharge unit Silo Discharge Machine is to extract wet, hot, cohesive, sluggish, and other non free flowing bulk material stored or buffered in bins or silos.
The rotating discharge arm conveys the bulk material toward the opening in the center of the floor and discharges it through this opening. To prevent the bulk material from flowing out in an uncontrolled manner, the discharge opening is covered by an inner cone. The discharge arm passes underneath the inner cone and activates the entire silo bottom during the discharge operation.
One revolution of this specially curved and profiled arm extracts a uniform disc of material from the silo. This keeps the bulk material column in motion and maintains its flow ability, preventing solidification of the bulk material over time and the risk of bridge formation and ratholing inside the silo.
Free Spinning Cone
The free spinning cone has the advantage of having no obstacles such as cross beams or cone supports that would disrupt the material flow. Very sticky or non-free flowing bulk materials have no chance to build bridges. This feature allows for a bulk material to have up to 3 times the amount of storage time at rest when compared with a cone supported by beams. This design should be used for wet bulk materials such as FGD Gypsum, Clay, Marl, etc.
Cone Supported by Beams
This design is used for bulk materials with poor flow characteristics, or for surge bins where long periods of storage time are not necessary. Typical bulk materials used in this machine are Limestone, Natural Gypsum, Ores, Coal, Petroleum Coke. Coarse or dry bulk materials can also be used with this machine.
Internal Drive
This feature gives you the advantage of storing very dusty bulk materials or materials that have the tendency for spontaneous combustion. One of the arms is built as an inspection tunnel, so drive maintenance can be done without emptying the silo. Typical applications are Pulverized Coal, Sub-Bituminous Coal (PRB coal), Wet Fly Ash and Land Plaster.
Benefits to You
- Optimizes storage space.
- Provides consistent, reliable discharging of your material.
- Continuous mass flow applicable to every industry.
- Heavy duty, reliable design minimizes downtime and maintenance.
The Silo Discharge Machine can be used in pits to efficiently empty rail cars or trucks, and in hoppers to unload clam shells or front-end loaders—or traditionally used in silos.
