Whether it is an animal feed pellet machine or a wood pellet machine, sometimes there is a problem of oil leakage from the spindle of the pellet machine. If there is no abnormal noise and no eccentricity, it is because the oil seal is broken, resulting in oil leakage!The main shaft of the straw/hemp/hops/husk pellet mill is a wear part, so it is the oil leakage phenomenon! Therefore, at the time of design, it was already reserved, so replacement was easy!

What is the reason for the oil leakage of the main shaft of the straw/hemp/hops/husk pellet mill?
What is the reason for the oil leakage of the main shaft of the straw/hemp/hops/husk pellet mill?

The solution to this problem is:

First, first clean up the material remaining in the gap between the main shaft and the rotor of the straw/hemp/hops/husk pellet mill.

Immediately after cleaning the filter in the particulate oil filter.

Then remove the grease lubricating block of the granulator, and use a hollow tube with a diameter of 4mm and a length of 497mm (effective length) to connect compressed air to insert the oil hole to clean the hole.

The oil in the oil hole was cleaned, and then the oil drum of the fuel pump was cleaned.

Clean the lubricating lubricating block of the granulator. After installing the lubricating lubricating block, start oiling with a bucket of new grease, and check whether there is any oil leakage in the refueling part.

Check the oil seal at the rear end of the rotor for oil leakage, and change the oil seal if necessary.

The next step. After the oil is pumped for ten minutes, the empty machine is turned on for about five minutes, and then the machine is stopped before the spindle is clean.

How To Choose A High-performance Biomass Pellet Machine

1. Pellet press manufacturers. A good pellet press machine manufacturer is a key factor for the pellet machine purchaser to buy a high-quality pellet machine. It is like ABC Machinery, who will supply superior machines to the clients, and that will get rid of a lot of troubles for the pellet press machine purchasers and give them the best service and after sale service.

2. The pellet considerations. Pellets quality is the direct standard of the pellet press machine quality. The pellets should be uniform, smooth, bright on the surface without cracks and the breakage rate of the pellet shouldn’t be more than 5%.

3. The ring die rotating situations. You should check whether the ring die will skip or rub other parts. For the above reason, it will decrease the yield and damage the ring die and other parts decreasing the pellet press service life span.

4. The appearance. The spray paint of the pellet machine surface and stainless steel/plating layer parts should be uniform, smooth and firm. A good looking pellet press surface reflects the pellet press equipment manufacturer’s extent of specialization.

5. The machine body and frame. You should check whether the pellet machine body and the frame are firm. Because they are the foundation of the whole pellet machine. The lock nut and the fastening bolt of the pellet press should be tightened.

6. The warehouse door. During the ring die pellet press machine production, you should check whether the warehouse door is designed in the right and suitable place and whether the door is opened and closed easily and whether the door leaks materials.

7. Test running. You can have a free test running of the pellet machine. Before the test running, you should check the lubricating condition of the gear box and the lubrication points. The first running doesn’t need to be too long, and the rotating direction of the spindle motor should be the same with the marked direction. If they are different, you should stop the machine and plug in phase commutation. After every thing is normal that is no irregular vibration, crash of gear, etc, you can feed materials.

The description of the short answer, I think everyone is very clear, if there are other aspects of the straw/hemp/hops/husk pellet mill, please consult online customer service!
