How to maintain an EPS foam granulator machine?

Posted by Kuajing Plus on October 8th, 2023

The waste EPS foam granulator is the main machine in the EPS foam granulating line. The foam granulator adopts high temperature melting, foaming and also is made into granules after a series of drawing, cooling, as well as cutting. In this procedure, the most important thing to take notice of is the heating of the host.

The concern that many clients often ask is: the first time you use it, you only need to heat it for half an hour; why the 2nd time you need to heat it for an hour? What is the reason?

This is since the continuing to be material on the screw did not flow out after the first day of production, causing the inside to cool down as well as solidify over night, so it took a long heating time to melt. In this situation, the blowtorch can be utilized to increase the temperature rise and make it melt quickly.

So the most essential thing is to keep the material flowing clean prior to shutting down. One is to save time, and the other is to save energy.

In addition, if the machine is not completely melted when the machine is started, it will raise the wear of the screw. In severe situations, it might cause damages to devices components. This is the most important part of our maintenance work. Furthermore, we need to add oil in time and also clean the parts regularly to keep the equipment in good condition at all times to get the best-finished product.

Long-term maintenance of EPS granulator

Below, we will introduce some maintenance knowledge about the foam granulator:

Inspect the working conditions of the rollers every six months, clean the bearings on the rollers with inflexible rotation, add grease, and change the worn or damaged bearings in time.

For the newly taken into the manufacturing of the foam recycling granulator, after the manufacturing test run time reaches 500 hours, all lubricating parts should be drained; the oil cup, fuel tank, pipeline, and filter should be cleaned, and then new filtered oil should be added.

Check the wear of the brushes of the DC motor once a month, adjust the contact setting of the brush as well as the shaft, replace the brush with a new one if needed, and also clean the fan on the electric motor at the same time.

The air source dual lubricator should be filled with turbine oil once a month, and also the moisture in the air filter need to be removed at the same time.

Sweep away the dirt in the electric control box quarterly or half a year, check the amount of lubricating oil in the oil tank and replenish the quantity of lubricating oil in time.

Clean the air filter on the gearbox every quarter or half a year, adjust the stress of the V-belt or chain, check the sealing ring (pad) in the pneumatic system, and also replace the worn parts when needed.
