The Gh

The Ghost Scooper™ is a patented rotary material distribution technology developed by PolyGhost Technologies that introduces a fundamentally new approach to industrial bulk material handling.

​

For decades, industries have relied on mechanical transport systems such as conveyors, augers, diverters, loaders, and manual labor to move and distribute dry or semi-solid materials.

​

These systems require:

• complex mechanical infrastructure
• large physical footprints
• multiple moving components
• high maintenance
• manual intervention

​

The Ghost Scooper replaces these mechanical transport systems with a rotational material acceleration system capable of projecting and distributing materials across space.

​

This creates an entirely new machine category:

​

Autonomous Dry Material Distribution Robots

​

This technology has the potential to transform a global material handling market across industries including wastewater treatment, mining, agriculture, food processing, and chemical manufacturing.

T

Industrial facilities that process bulk materials must constantly move, fill, and distribute materials into containers, storage bays, trucks, or stockpiles.

​

In sludge dewatering plants, for example, dried sludge cake must be transferred into roll-off dumpsters or storage areas.

​

Traditional solutions include:

​

• pivoting conveyor systems

• mobile conveyor systems

• chute diverters

• container repositioning equipment

• skid-steer loaders

• manual shoveling

​

These approaches are:

• capital intensive
• mechanically complex
• labor dependent
• inefficient
• unsafe in some environments

​

The industry has accepted these limitations for decades because no alternative distribution technology existed.

PolyGhost developed the Ghost Scooper, a rotary distribution mechanism capable of capturing, accelerating, and distributing bulk materials through controlled rotational motion.

Instead of transporting materials mechanically across space, the Ghost Scooper projects materials through space using controlled centrifugal acceleration.

​

Material enters the scooper directly from a conveyor outlet and is immediately captured by rotating scoop blades.

The rotating impeller then accelerates the material outward and distributes it across a target area.

This process allows the system to:

• distribute materials across containers
• spread materials across storage bays
• form stockpiles
• fill multiple containers automatically
• eliminate mechanical distribution infrastructure

​

The Ghost Scooper technology operates using several physical principles.

​

Centrifugal Material Acceleration

The rotating rotor generates centrifugal force that accelerates material outward along the scoop geometry.

The final discharge velocity depends on:

• rotor radius
• rotor rotational speed
• blade geometry
• material density and friction properties

This velocity determines the distribution distance and coverage area.

 

Controlled Material Trajectory

By adjusting rotor speed using a variable frequency drive (VFD), the system can dynamically control:

• distribution distance
• spread width
• pile formation behavior
• fill patterns

This allows operators to adapt the distribution behavior to specific materials and container geometries.
 

Continuous Flow Distribution

Because the rotor continuously captures and accelerates incoming material, the system can process steady conveyor flows without interruption.

Unlike mechanical distribution systems, no additional transport mechanisms are required.

Linear Material Distribution Systems

​

The GSL platform distributes materials in a linear pattern beneath a conveyor outlet.

Typical applications include:

• roll-off dumpster filling
• sludge storage bays
• compost windrow formation
• stockpile creation

The system integrates directly with U-trough screw conveyors or belt conveyor outlets, allowing easy retrofit installation in existing facilities.

GSL360 Platform - 360° Material DGSL360 Platform

 

360° Material Distribution Systems

The GSL360 platform incorporates a rotating base that enables full 360-degree distribution coverage.

​

This allows the scooper to fill:

• multiple dumpsters
• large storage bays
• compost processing areas
• mining stockpiles

​

The rotational base uses a slew ring mechanism that dynamically reorients the distribution direction. This greatly expands the coverage area without requiring additional conveyors.

Autonomous Material Distribution Robots

​

The Ghost Scooper Ai360 represents the next evolution of the platform: fully autonomous material distribution robots.

​

These systems integrate:

• industrial robotics
• machine vision systems
• AI control algorithms
• automated rotor speed control

​

Using vision cameras and sensors, the robot can:

1. Scan the available container or storage area.

2. Detect empty zones requiring material.

3. Adjust rotor RPM to control distribution distance.

4. Rotate the system to target the correct area.

5. Continuously monitor fill levels.

6. Automatically complete the filling process.

 

This creates a new category of self-optimizing bulk material distribution systems.

Materials Compatibility

The Ghost Scooper™ technology is designed to handle a wide range of dry, semi-dry, and semi-solid bulk materials.

​

The rotary scooper impeller accelerates and distributes materials through controlled centrifugal motion, allowing efficient handling of materials with varying densities, moisture levels, and particle sizes.

​

The system performs best with free-flowing to moderately cohesive bulk solids, but it can also handle heavier materials such as sludge cake, mineral solids, and municipal grit.

​

Typical material compatibility includes:

​​

Wastewater & Environmental Materials

​

• Dewatered sludge cake (18–32% dry solids)
   

• Biosolids
   

• Compost
   

• Digestate solids
   

• Lime-stabilized sludge
   

• Soil amendments
   

• Municipal grit from grit removal systems
   

• Grit washer discharge solids
   

 

Agricultural Materials

​

• Fertilizers
   

• Soil conditioners
   

• Compost blends
   

• Organic waste solids
   

• Animal feed ingredients
   

 

Industrial Bulk Solids

• Plastic regrind
   

• Rubber granules
   

• Chemical powders
   

• Industrial catalysts
  
   

 

Mining & Mineral Materials

Material Characteristics

​

The Ghost Scooper system can accommodate materials with a wide range of physical characteristics:

​

• particle sizes from fine powders to coarse granules

• bulk densities ranging from lightweight organics to dense mineral solids

• moisture contents from dry powders to semi-solid materials

​

Material distribution behavior can be optimized by adjusting:

​

• rotor geometry
   

• rotor speed (RPM)
   

• Ghost Scooper configuration (2-blade, 3-blade, or 4-blade rotors)
   

• installation height and discharge orientation
   

This flexibility allows the Ghost Scooper platform to support municipal, industrial, agricultural, and mining applications using the same core technology.
