Mobile Inclined Screw Conveyor with Hopper (Custom Portable Auger)

The Mobile Inclined Screw Conveyor with Hopper integrates the drive motor, rotating screw, charging hopper, and bottom casters into a single steel frame chassis. By rotating the screw inside the enclosed tube, the machine lifts powder or granular materials to higher locations at an incline angle of 30° to 60°. Standard models cover conveying capacities from 1 m³/h to 20 m³/h, and material-contact parts can be manufactured from carbon steel, 304 stainless steel, or 316L stainless steel.

Key Advantages: Combining Mobile Mobility with Integrated Hopper Feeding

On industrial production sites, traditional fixed elevating equipment often causes operational obstacles due to rigid workstations and excessively high feed inlets. The Mobile Inclined Screw Conveyor with Hopper overcomes these limitations through structural re-engineering:

• Easy Manual & Forklift Loading: The low-profile open design of the industrial hopper reduces loading height, allowing operators to pour bags or bulk sacks directly into it, or forklifts to unload directly at the inlet without requiring elevated platforms.
• Multi-Point Factory Utility: Equipped with heavy-duty lockable polyurethane casters on the chassis, a single operator can push the equipment to different production lines or storage tanks, replacing multiple fixed pipelines and reducing equipment purchasing costs.
• Dust-Controlled Incline Handling: The fully enclosed tube body combined with a covered stainless steel hopper blocks the dispersion of fine dust during inclined lifting, preventing material spillage and workshop contamination.

Where Is It Used? (Application & Industries)

This equipment is commonly used in material handling scenarios requiring frequent changes of feeding locations:

In plastic processing plants, it is used to feed resin pellets into high-position injection molding hoppers; at grain storage points, it replaces portable incline conveyors to lift soybeans or grains to screening machines; in building material workshops, it works with feeding hoppers to pour cement powder or lime powder into mixing tanks. For dry powder packaging lines requiring high cleanliness, the tube body with sanitary incline conveyor details can be moved to the cleaning area for water washing at any time.

Tailored Options for Your Specific Process

According to specific physical material properties and environmental requirements, the following custom configurations are available:

• Hopper Accessories: Pneumatic vibrators or anti-bridging agitator shafts are installed on the hopper wall to eliminate powder sticking.
• Drive Systems: Equipped with a Variable Frequency Drive (VFD) for fine speed adjustment, or motors with specific explosion-proof ratings.
• Mobility & Lifting: Equipped with a manual hydraulic lifting pump to adjust discharge height and incline angle.

Choosing the Right System: Mobile Inclined Screw Conveyor vs. Portable Inclined Belt Conveyor

For inclined conveying needs, the table below compares the technical differences between this equipment and various incline conveyor belts (such as slider bed conveyors or small incline belt conveyors):

Comparison Dimension	Mobile Inclined Screw Conveyor	Portable Inclined Belt Conveyor
Material Sealing	Fully enclosed tube, preventing dust dispersion	Open conveying, prone to dust or material falling
Incline Angle Limit	Up to 60°, small footprint	Usually kept under 30° (even for high incline types)
Cleaning & Maintenance	Quick-open cleanout door at bottom, easy to clean tube cavity	Material tends to accumulate on back of belt, cleaning is complex
Applicable Categories	Powders, small granules, and moist/sticky materials	Bulk materials, boxed goods, or fragile finished products

Frequently Asked Questions

Q1: How do I choose the correct hopper dimensions for my process?

Answer: It depends on the volume and method of each feeding operation. If feeding with bulk bags, select hopper incline conveyor dimensions with an opening width greater than 1200 mm; for manual bag pouring, a standard hopper of 100 L to 200 L is sufficient.

Q2: Can this machine handle cohesive or sticky powders without clogging?

Answer: Yes. For powders prone to clumping, a Shaftless Screw structure can be selected, along with an electromagnetic vibrator installed on the hopper side wall to prevent material blockages at the inlet.

Q3: What motor power and voltage options are available for international export?

Answer: Customized motors are provided in three-phase 220V / 380V / 415V / 460V, with frequencies of 50Hz or 60Hz, complying with wiring standards in different regions such as Europe and America.

Manufacturing Standards & Quality Assurance

The manufacturing process strictly complies with CE certification standards and the ISO9001 quality management system. Stainless steel parts contacting materials undergo acid pickling, passivation, or 240-mesh polishing, with welds non-destructively tested and ground smooth. The entire machine undergoes no-load test runs before leaving the factory to measure motor current, noise levels, and bearing temperature rise.

How to Get an Accurate Quote

To obtain an accurate parameter evaluation and factory-direct quote, please provide technical personnel with the following four specific details when inquiring: material name and bulk density (kg/m³), required conveying capacity per hour (m³/h), vertical discharge height from ground level (mm), and factory power voltage specifications.
