Details

This equipment is a general-purpose automated conveying device. It uses a rotating screw within an enclosed tube to horizontally or incline transport powder, granular, and small lump materials from a storage bin to a processing machine hopper. It is widely used as auxiliary equipment for extruders, mixers, and granulators.

Core Advantages

Automated feeding reduces labor intensity and improves production efficiency.

The simple sealed structure prevents dust leakage and keeps the work area clean.

Flexible installation allows horizontal, inclined, or multi-unit series conveying.

Easy maintenance requires no frequent filter cleaning compared to vacuum conveyors.

Stainless steel material contact parts ensure hygiene, corrosion resistance, and long service life.

Product Features

This screw feeder has an enclosed tube for dust-free operation, adjustable screw speed, stainless steel contact parts, flexible installation for horizontal or inclined use, reverse conveying option, compact design, low cost, reliable operation, and easy maintenance without frequent filter cleaning.

Product Applications

This equipment is suitable for feeding powders, granules, and recycled regrind in the plastic, chemical, food, feed, pharmaceutical, building material, and metallurgical industries. It is commonly used with extruders, high-speed mixers, blenders, injection molding machines, and dryers.

Precautions

Install the screw feeder on a stable, level surface to prevent vibration and misalignment. Ensure all connections are sealed before operation to avoid dust leakage. Do not exceed the rated conveying capacity or feed materials that are highly sticky, corrosive, or exceed the specified temperature limit. Regularly inspect the screw blade and tube liner for wear. Disconnect power and lock out the control panel before cleaning, maintenance, or removing any blockage. Lubricate bearings according to the maintenance schedule.

FAQ

Q: Can the same screw feeder handle both fine powders and coarse granules?

A: Yes, but performance may vary. Fine powders flow more easily, while coarse granules may require a larger screw diameter or slower speed to prevent jamming. We recommend confirming material characteristics before selection.

Q: How often should the screw and tube be cleaned?

A: Cleaning frequency depends on the material. For sticky or hygroscopic products, clean after each batch. For free-flowing, non-sticky materials, cleaning once per week or during product changeovers is usually sufficient.

Q: What should I do if the screw feeder stops suddenly during operation?

A: First, disconnect power. Then check for material bridging at the inlet, a foreign object jam inside the screw, or an overload trip on the motor drive. Clear any blockage and reset the protection device before restarting.
