EXTRUTEX Immediately Recycling Crusher Series
Low-Noise, Dust-Free, High-Efficiency Granule & Powder Crushing Systems

Introduction to the EXTRUTEX Immediately Recycling Crusher

In modern production lines, the ability to reduce particle size quickly, cleanly, and with minimal waste is a critical competitive advantage. Whether reprocessing plastic edge trim, preparing pharmaceutical powders, or producing uniform granules for food and chemical applications, manufacturers need equipment that is reliable, easy to integrate, and safe for operators. The EXTRUTEX Immediately Recycling Crusher series was developed to meet exactly these requirements.

Designed in Austria and manufactured in state-of-the-art facilities in Nanjing and Shanghai, China, every machine embodies a philosophy of precision engineering, hygienic construction, and practical usability. The “Immediately Recycling” concept means that the crushed material can be returned directly to the process via a blower or suction system, eliminating intermediate handling, reducing dust exposure, and maximizing material yield.

The series covers a practical capacity range from 15 kg/h to 80 kg/h, with chamber calibres from 200 × 180 mm up to 290 × 270 mm. All models share core advantages: low-speed operation for reduced noise and dust, double-layer pulverizing technology for high efficiency, strainer-free design for uniform particle size, multi-level CE-compliant safety protection, and a compact footprint that is easy to move and install.

These crushers are widely used in plastics recycling, pharmaceutical intermediate preparation, food ingredient processing, chemical powder production, and any application where controlled, dust-free size reduction is essential. The modular design allows customers to choose between basic configurations or fully integrated systems that include material storage tanks, proportional valves, autoloaders, and hopper dryers.

Performance Characteristics

Six key performance pillars define the EXTRUTEX Immediately Recycling Crusher range. Each has been engineered to solve real production challenges.

Low-speed operation is one of the most important advantages. High-speed crushers often generate excessive noise and throw fine dust into the air, creating both environmental and occupational-health problems. By running at carefully selected lower speeds, the EXTRUTEX crusher keeps noise levels comfortable for operators and keeps dust generation to a minimum. This is especially valuable in clean-room environments, food plants, and pharmaceutical facilities.

The double-layer pulverizing system separates the size-reduction process into coarse and fine stages within the same chamber. Material first encounters the primary crushing elements and is then refined by the secondary stage. The result is higher overall efficiency and a narrower particle-size distribution than single-stage machines of similar power.

Because the design does not rely on a traditional perforated strainer or screen, there is no risk of screen blockage when processing sticky, moist, or heat-sensitive materials. The granules that leave the chamber are already uniform, and the absence of a screen further reduces dust generation. This “no strainer” approach also simplifies cleaning and changeover between different products.

Safety is built in according to CE requirements. Interlocks, emergency stops, and protective covers ensure that the machine cannot be operated in an unsafe condition. The multi-level protection system gives production managers confidence that operators are safeguarded throughout the shift.

The immediate recycling capability is a defining feature of the series. By adding a blower or suction unit, the crushed material can be transported pneumatically back to a storage tank, mixer, or extruder hopper without manual handling. This closed-loop approach maximises yield, minimises contamination risk, and keeps the working environment cleaner.

Finally, the compact dimensions and relatively low weight of each model make installation and relocation straightforward. In factories where floor space is limited or production layouts change frequently, the ability to move the crusher with minimal effort is a significant practical advantage.

Working Principle and System Integration

The EXTRUTEX Immediately Recycling Crusher uses a rotating set of blades or hammers inside a carefully designed chamber. Material is fed into the chamber either manually, by autoloader, or via a proportional valve from an upstream process. Once inside, the low-speed rotating elements impact and shear the material between the blades and the chamber wall or secondary crushing surfaces.

Because the chamber is engineered for progressive size reduction, larger pieces are broken first and smaller particles continue to be refined until they reach the desired size. The absence of a screen means that material exits when it has been sufficiently reduced by the mechanical action itself, rather than by passing through fixed openings. This produces a more uniform granule and avoids the fine dust that often results from high-speed screening.

Two typical system layouts are illustrated in the construction diagrams:

• Layout with Material Storage Tank – The crusher is paired with a storage hopper. Material can be fed from the tank through a proportional valve, crushed, and then returned or directed to the next process stage. An autoloader can be added for continuous supply.
• Layout with Hopper Dryer & Blower – A more complete closed-loop system that includes a hopper dryer, proportional valve, blower, and the immediately recycling crusher. Crushed material is pneumatically conveyed back into the process, ideal for plastics reprocessing or continuous powder production.

Model suffixes indicate the configuration:

• -2B – Standard equipment includes the material storage box / tank.
• -2C – Version prepared for proportional valve (and often used with blower or suction recycling).

When a loader is specified, the model designation receives the “2B” suffix; when a proportional valve is specified, the “2C” suffix is added. This clear coding system helps customers and engineers specify the exact machine required for their line.

Typical Applications Across Industries

The versatility of the EXTRUTEX Immediately Recycling Crusher makes it suitable for a wide range of materials and processes:

• Plastics industry – Edge-trim and scrap recycling, regrind for extrusion or injection moulding, size reduction of PET, PE, PP, ABS, and engineering plastics.
• Pharmaceutical & nutraceutical – Controlled size reduction of intermediates, herbal materials, and excipients where dust control and uniform particle size are critical.
• Food industry – Crushing of spices, sugar, starch agglomerates, dried vegetables, and other ingredients that benefit from low-dust, low-heat processing.
• Chemical industry – Size reduction of pigments, resins, catalysts, detergents, and specialty chemicals.
• Recycling & circular economy – Immediate reprocessing of production scrap so that material returns to the process with minimal degradation and handling.

In all of these sectors the combination of low noise, low dust, uniform output, and the option of immediate pneumatic recycling delivers measurable improvements in product quality, workplace safety, and material yield.

Construction Layout and Main System Components

A complete EXTRUTEX Immediately Recycling Crusher system can include the following elements (depending on the chosen configuration):

• Immediately Recycling Crusher – The core pulverizing unit with double-layer crushing chamber.
• Material Storage Tank – Buffer hopper that holds material before or after crushing.
• Proportional Valve – Controls the feed rate of raw material into the crusher.
• Autoloader – Automatic feeding device for continuous operation.
• Blower / Suction Fan – Pneumatic conveying of crushed material back to the process.
• Hopper Dryer – Optional drying stage for moisture-sensitive materials before or after crushing.
• Control System – Start/stop, safety interlocks, and optional speed or feed control.

The modular nature of the design allows customers to start with a basic crusher and later add recycling, storage, or drying modules as production needs evolve. All product-contact parts are manufactured from high-quality materials suitable for the intended industry (stainless steel options are available for food and pharmaceutical use).

Installation, Operation and Maintenance

Installation of an EXTRUTEX Immediately Recycling Crusher is straightforward. The compact footprint allows the machine to be positioned close to the process it serves. Smaller models can often be moved by pallet truck or forklift; larger or system-integrated units may require more planning for pneumatic ducting and electrical connections.

A solid, level floor is recommended. When the crusher is part of a closed-loop recycling system, attention should be paid to the routing of suction or blower lines so that conveying distances remain reasonable and pressure losses are minimised.

Typical daily operation follows these steps:

1. Confirm that all safety covers and interlocks are in place and functional.
2. Start the crusher motor and, if fitted, the blower or suction unit.
3. Begin feeding material at a controlled rate (manual, autoloader, or proportional valve).
4. Monitor the process for smooth operation; the low-speed design normally produces a steady, quiet crushing action.
5. When the batch or continuous run is complete, stop the feed, allow the chamber to empty, then stop the motor and conveying system.
6. For product changeovers, open the chamber according to the safety procedure and clean contact surfaces as required.

Routine maintenance is limited. Bearings should be lubricated according to the schedule in the manual, blades or hammers inspected periodically for wear, and safety switches tested regularly. Because the machine runs at relatively low speed and does not rely on a fine screen, wear rates are generally moderate and spare-part consumption is low.

Safety Features in Detail

Operator safety is a core design priority. The multi safety protection system that conforms to CE standards typically includes:

• Interlocked access covers that stop the motor when opened.
• Emergency-stop buttons located within easy reach.
• Motor overload protection.
• Guarding of all rotating and pinch points.
• Clear warning labels and operating instructions.

These measures, combined with the inherently lower noise and dust levels of the low-speed design, create a safer working environment than many conventional high-speed crushers. For installations handling combustible dusts, optional explosion-protection measures can be discussed with the EXTRUTEX engineering team.
