How to protect the transmission box of the twin-screw extruder?

When using a twin-screw extruder, reasonable maintenance of the machine is conducive to prolonging the service life of the machine, so when using a twin-screw extruder, the transmission box must be actively protected, so besides this, what is the protection of the transmission box of the twin-screw extruder? What are the reasons? What are the specific protection methods and precautions? Here, TENGDA Plastic Extruder Machine Manufacturers specially compiled relevant information for everyone

Why should the transmission box of the twin-screw extruder be protected?

This question mainly depends on its function. Look at mine and you may understand why the transmission box of the twin-screw extruder should be protected.

1. Blend plastics of different varieties and grades into homogeneous plastic alloys or blends to obtain polymer materials with new comprehensive properties.

2. Adding various inorganic fillers, such as calcium carbonate and talcum powder, to plastics can greatly reduce the cost of raw materials and improve their physical and mechanical properties.

3. Mixing various additives in plastics, such as stabilizers, flame retardants, colorants and preparation of high-concentration masterbatches, etc., can obtain highly dispersed mixing effects

4. Add reinforcing materials, such as glass fiber and carbon fiber, to the plastic to improve the physical and mechanical properties of the plastic.

5. Polymer homogeneous granulation, such as eliminating fish eyes, improving transparency, etc.

6. Exhaust and devolatilization, that is, to remove various volatile components such as monomers, solvents, water, and oligomers remaining in the polymer while plasticizing and kneading.

7. With optimized screw combination, this machine can also be used in special fields such as mixing and granulation of various powder materials and thermosetting plastics, and reactive extrusion of polymers.

How to protect the transmission box of the twin-screw extruder?

1. Clean the box and oil filter when changing the oil. After clarifying the lubricating oil used this time, put the clean lubricating oil into the box again, clean the box once, release it, and put it in again. New lube.

2. After 500 hours of use, replace the lubricating oil once.

3. The transmission box of the twin-screw extruder is lubricated with No. 150 original medium-pressure gear oil.

4. The oil level in normal operation should not be lower than the center line of the oil mark. If it is lower than the center line, please replenish it as soon as possible.

5. Change the oil after every 3000 hours of use.

6. The transmission box of the twin-screw extruder should clean the lubricating oil filter every month during normal use, and clean the lubricating oil filter every week during the running-in period. The cleaning method is to find the oil filter, open it, and take out the dirt in it.
