HTE Series Co-Rotating Parallel Twin Screw Extruders

HTE Series Co-Rotating Parallel Twin Screw Extruders

The HTE series co-rotating parallel twin screw extruders from Nanjing Hundred Horse are designed for masterbatch production, plastic compounding, engineering plastics, biodegradable materials, thermoplastic elastomers, cable compounds, wood plastic composites, and plastic recycling.

The series includes different extruder sizes and torque configurations to match different production targets. According to the material, formulation, and required output, each extruder can be configured with a suitable motor, gearbox, screw design, barrel arrangement, feeding system, and downstream pelletizing equipment.

From general masterbatch production to demanding compounding applications, the HTE series provides a flexible solution for manufacturers who need stable processing, efficient mixing, and reliable continuous production.

Different Extruder Sizes and Torque Configurations

HTE extruders are available in several screw diameter sizes, including HTE35, HTE40, HTE50, HTE52, HTE65, HTE75, and HTE95. The model number mainly refers to the screw diameter range, while the torque class defines the strength of the motor, gearbox, shaft system, and processing capability.

This means that the same extruder size can be supplied in different configurations. For example, an HTE50 standard torque extruder and an HTE50 high torque extruder have the same screw diameter, but different motor power, torque, and output range.

This structure helps customers choose a machine based on real production needs instead of selecting only by screw diameter.

Standard Torque, High Torque, and Super High Torque

The HTE series is available in three main torque classes. Each torque class is designed for a different processing range, from normal masterbatch production to heavy-duty compounding.

Torque Class	Main Characteristic	Suitable Applications
Standard Torque	Balanced configuration for regular production	Color masterbatch, filler masterbatch, additive masterbatch, general compounding, and recycling
High Torque	Stronger processing capability and higher output range	Engineering plastics, reinforced compounds, flame-retardant compounds, cable compounds, and high filler masterbatch
Super High Torque	Heavy-duty configuration for demanding formulations	High-output production, high glass fiber loading, high filler loading, and difficult-to-process materials

Standard Torque Series

The standard torque series is suitable for regular production of masterbatch, plastic compounds, and recycled plastic pellets. It offers a practical balance between output capacity, equipment cost, and processing performance.

Model	Screw Diameter	Motor Power	Torque per Single Screw	Screw Speed	Capacity
HTE20	22 mm	4 kW	34 N·m	600 rpm	2–10 kg/h
HTE35	35.6 mm	22 kW	157 N·m	600 rpm	30–100 kg/h
HTE40	41.1 mm	30 kW	238 N·m	600 rpm	50–150 kg/h
HTE50	50.5 mm	55 kW	430 N·m	600 rpm	100–250 kg/h
HTE52	51.4 mm	55 kW	461 N·m	600 rpm	100–300 kg/h
HTE65	62.4 mm	90 kW	816 N·m	600 rpm	200–400 kg/h
HTE75	71 mm	160 kW	1,253 N·m	600 rpm	400–1,000 kg/h
HTE95	94 mm	315 kW	2,752 N·m	600 rpm	1,000–2,500 kg/h

HTE20 is mainly used for laboratory testing and small-batch development. For this model, please refer to the dedicated laboratory extruder page.

High Torque Series

The high torque series is designed for applications that need stronger processing performance than the standard series. It is commonly used for reinforced plastics, engineering compounds, high filler masterbatch, flame-retardant materials, and cable compounds.

Model	Screw Diameter	Motor Power	Torque per Single Screw	Screw Speed	Capacity
HTE35	35.6 mm	30 kW	238 N·m	600 rpm	50–200 kg/h
HTE50	50.5 mm	90 kW	652 N·m	600 rpm	200–400 kg/h
HTE65	62.4 mm	160 kW	1,237 N·m	600 rpm	400–800 kg/h
HTE75	71 mm	250 kW	1,901 N·m	600 rpm	800–1,500 kg/h

Super High Torque Series

The super high torque series is the heavy-duty configuration of the HTE range. It is suitable for customers who require higher production capacity, stronger torque, and stable processing of demanding formulations.

Model	Screw Diameter	Motor Power	Torque per Single Screw	Screw Speed	Capacity
HTE50	50.5 mm	110 kW	874 N·m	600 rpm	250–500 kg/h
HTE65	62.4 mm	200 kW	1,659 N·m	600 rpm	500–1,000 kg/h
HTE75	71 mm	315 kW	2,549 N·m	600 rpm	1,000–2,000 kg/h

Example: HTE50 Configuration Comparison

The HTE50 model can be supplied in different torque configurations. Although the screw diameter remains 50.5 mm, the motor power, torque, and output capacity are different.

This example shows why the same model number may appear in more than one technical table. The model number identifies the screw diameter, while the torque class defines the actual processing strength of the machine.

Model	Torque Class	Screw Diameter	Motor Power	Torque per Single Screw	Capacity
HTE50	Standard Torque	50.5 mm	55 kW	430 N·m	100–250 kg/h
HTE50	High Torque	50.5 mm	90 kW	652 N·m	200–400 kg/h
HTE50	Super High Torque	50.5 mm	110 kW	874 N·m	250–500 kg/h

How to Choose the Right HTE Extruder

Choosing the right twin screw extruder depends on the formulation, target output, and production conditions. Screw diameter is important, but it is not the only factor. Motor power, gearbox torque, screw design, feeding method, venting, and pelletizing system also affect the final result.

• For general masterbatch and normal compounding: Standard torque series is usually suitable.
• For reinforced plastics, high filler content, and engineering compounds: High torque series is recommended.
• For heavy-duty production and difficult formulations: Super high torque series provides stronger processing capability.
• For laboratory testing and small-batch trials: HTE20 laboratory extruder is the recommended solution.
