Product Description

Function and principle: The screw conveyor dryer moves material through the drying chamber using a rotating screw assembly. During operation, the material is conveyed and turned as it passes through the machine. The drying process depends on the configured heating system and operating conditions. Feed rate, screw speed and temperature control should be described according to the actual machine configuration.

Conventional types and parameters:

Model number	Single axis version (including feeding function)	Dual axis version (including feeding function)	Dual axis version	Three axis version
Power	23.2 kW	46.4 kW	43.5 kW	65.2 kW
per hour production capacity	0.5-1 tons	1-1.5 tons	1-2 tons	2-3 tons

Screw Conveyor Dryer

Note:

1. Models equipped with a feeding system combine material feeding and drying in one machine.

2. The processing capacities listed above are based on plastic woven bag material. Actual throughput may vary depending on material type, initial moisture content and operating conditions.

Working principle: The material enters the equipment cavity, Move forward along the parallel spiral channel, Under the dual effects of agitation, flipping, and thermal conduction, Ensure sufficient contact between the material and the inner wall of the equipment, as well as between the material and the hot air, The material moves continuously through the drying chamber. Under the specified operating conditions, the typical material residence time is approximately 1–3 minutes.

Industry specific advantages:

	Hongxu Machinery	Traditional dryer
Hot drying effect	The enclosed design helps contain material within the drying chamber, while the screw assembly conveys and turns the material during operation. The actual drying performance depends on the heating configuration, material characteristics and operating conditions.	Some models have non enclosed structures, Excessive waste of heat efficiency.
Material adaptability	Can simultaneously process various waste plastics such as PET hard sheets, PE/PP soft films, ABS/PC engineering plastics, etc.	Most can only handle a single material or materials of the same type.
degree of automation	Can connect the cleaning equipment and sorting equipment of the front and back ends, The entire sorting line runs continuously without interruption.	Most dryers cannot achieve continuous and uninterrupted operation, Excessive labor consumption.

Screw Conveyor Dryer

Core components and highlights of Hongxu Mechanical screw conveyor dryer:

1.Main Frame: The machine frame supports the main assemblies and provides structural stability during operation. Carbon steel or stainless steel construction can be specified according to the available configuration.

2. Screw Assembly: The screw assembly conveys material through the drying chamber. The material and wear-protection options should be specified according to the actual machine configuration.

3. Drive and control system: Can be equipped with variable frequency speed control motors and reducers, Realize precise and controllable temperature and speed.

Common troubleshooting:

1. Excessive moisture content in the discharge: Mostly due to fast feeding frequency and large volume, Due to low temperature, Adjust the feeding rhythm and volume, Under normal circumstances, it can be restored by increasing the temperature.

2. Abnormal vibration of equipment: Usually, a large amount of material entering the cavity at once or entering hard objects causes equipment jamming, Reduce the amount of materials put in at once or stop the machine to remove hard objects, In general, obstacles can be eliminated.

3. Unstable temperature control: Check the heating tube and temperature sensor, After replacing the faulty parts, it can generally be restored.

FAQ

1. What materials can the Screw Conveyor Dryer handle?

The Screw Conveyor Dryer is designed for drying washed plastic materials, such as plastic sheets and films used in recycling processes. Depending on the machine configuration and operating conditions, it may also be suitable for other plastic materials. Please provide the material type, size and initial moisture content to confirm compatibility with the selected model.

2. What is the processing capacity of the Screw Conveyor Dryer?

The listed processing capacity ranges from 0.5 to 3 tons per hour, depending on the model. Actual throughput may vary according to the material type, initial moisture content, feeding conditions and operating parameters. The capacity figures provided for this equipment are based on plastic woven bags, so testing or technical confirmation is recommended when processing other materials.

3. How does the Screw Conveyor Dryer work?

The Screw Conveyor Dryer moves material through the drying chamber using a rotating screw assembly. As the screw conveys and turns the material, the configured heating system supports moisture removal during continuous operation. The actual drying process depends on the machine's heating configuration, material characteristics and operating conditions.

4. Can the Screw Conveyor Dryer be integrated into an existing plastic recycling line?

The Screw Conveyor Dryer can be configured for integration with compatible upstream and downstream equipment in a plastic recycling line. Before installation, the feeding method, discharge position, connection dimensions, processing capacity and available installation space should be checked to ensure that the dryer matches the existing production process.

5. How do I choose the right Screw Conveyor Dryer model?

Model selection depends on the type of plastic material, required processing capacity, initial moisture content, target moisture level and production line configuration. Hongxu Machinery offers single-axis, dual-axis and three-axis configurations with different power ratings and processing capacities. Providing your material details and production requirements will help determine the appropriate model.
