PP/PE Two-Stage Pelletizing Line
**Application & Features:**
This two-stage pelletizing line is designed for efficient recycling and processing of plastic waste, particularly for materials like PP and PE. The first stage uses an SHJ twin-screw extruder without a die, allowing it to melt, compound, disperse, and deagglomerate thermosensitive materials such as PVC under no backpressure conditions. This ensures better control over the material's properties during processing.
The second stage involves a single-screw extruder (SJ series), which operates at a lower rotational speed. This helps in achieving steady melting, thorough compounding, and consistent strand formation, minimizing the risk of overheating and ensuring high-quality output.

II. Structural Composition:
1. Gear:
The gear is the core component of the excavator travel reducer and is responsible for transmitting power and realizing the deceleration function. Different types of excavator travel reducer may use different gear types, such as planetary gears. The hardened gear can withstand a large load and ensure the service life of the reducer.
2. Housing:
The housing plays a role in protecting the internal structure and also provides installation and support for gears and other components. The material and manufacturing process of the housing have an important impact on the strength and sealing performance of the reducer. ZHTE HYDRAULIC has a professional casting line, and each process is inspected by professionals to ensure quality.
3. Shaft:
It is used to connect gears and other components and transmit power. The material and processing accuracy requirements of the shaft are relatively high to ensure stability and reliability under high-speed rotation and high load.
4. Bearing:
It supports the rotation of the shaft and reduces friction and wear. High-quality bearings can improve the operating efficiency and service life of the reducer.
III. Working Principle:
Excavator travel reducer usually use the meshing of gears to achieve the function of deceleration and torque increase. When the high-speed rotating power provided by power sources such as motors or engines is input into the reducer, through the gear transmission system inside the reducer, the speed is reduced and the torque is increased at the same time to meet the power requirements of walking equipment under different working conditions. For example, planetary gear reducers achieve efficient deceleration transmission through the cooperation of the sun gear, planetary gears, and ring gear.
IV. Performance Characteristics:
1. Large reduction ratio:
It can reduce the input high-speed rotation to a low speed suitable for walking equipment and provide sufficient torque for the equipment to overcome various resistances.
2. Strong load-carrying capacity:
Since walking equipment usually needs to carry a large weight and load, excavator travel reducer need to have a high load-carrying capacity. By using high-quality materials and advanced manufacturing processes, excavator travel reducer can operate stably for a long time in harsh working environments.
3. Reliable operation:
After strict design and testing, excavator travel reducer have good reliability and stability and can ensure the normal operation of walking equipment.
V. Maintenance:
1. Regularly change lubricating oil:
Lubricating oil can reduce friction and wear between gears and extend the service life of the reducer. Lubricating oil needs to be changed regularly according to the usage of the reducer and the manufacturer's recommendations.
2. Check the wear condition of parts:
Regularly check the wear condition of parts such as gears, shafts, and bearings, and replace severely worn parts in time.
3. Keep clean:
Keep the reducer clean and avoid dust, debris, etc. from entering the reducer and affecting its normal operation.
