Fault prevention of flat die pellet machine

We often find that flat die pellet machines will have large and small failures in the process of production and use. These failures not only affect the efficiency of product production, but also cause excessive cost input. We often talk about preventive measures. Here are some points for attention in the use of flat die pellet machine.

  1. Check the parts regularly to see if the work is normal. Whether the bearing and other moving parts are flexible or worn. If defects are found, they should be repaired in time.
  2. The flat die pellet machine should be used in dry room, and it can't be used in corrosive gas flow places such as acid in atmosphere.
  3. When the flat die pellet machine is used or stopped, the rotating drum shall be taken out for cleaning and brushing the remaining powder in the bucket, and then installed to prepare for the next use.
  4. If the shutdown time is too long, the whole body of the flat die pellet machine must be wiped clean, the smooth surface of the machine parts should be coated with rust-proof oil and covered with cloth.

The above work can greatly reduce the occurrence of flat die pellet machine failures, so that its production efficiency can up to the higher level.

Cause and solution for premature damage of flat die pellet machine bearings

After the flat die pellet machine was purchased, the flat die pellet machine bearing was damaged early. At this time, many customers will think that the quality of the bearings produced by the pellet machine manufacturer is not good enough. In fact, most people do not know that the general bearing burnout is not the quality reason, but the use of improper customer operation. Here are the following four reasons for your reference.

Improper installation

  • Brute force is used during installation. Hitting the bearing directly with a hammer causes the greatest damage to the bearing. It is the main cause of deformation.
  • Installation is not in place, deviation or not installed to bearing position, resulting in bearing clearance too small. The inner and outer circles are not in the same rotating center, causing different concentricity.

Suggestion: choose proper or professional bearing installation tools and check them with special instruments.

Poor lubrication

According to investigation, poor lubrication is one of the main reasons for premature bearing damage. The main reasons include not filling lubricant or lubricating oil in time, not filling lubricant or lubricating oil in place, improper selection of lubricant or lubricating oil, improper lubrication mode, etc.

Suggestion: choose the right lubricant or lubricating oil and use the correct way of lubricating filling.


Pollution also leads to premature damage to the bearing. Pollution means that dust and metal chips enter the bearing. The main reasons include pollution caused by opening the packing of bearings prematurely before use, pollution caused by unclean working environment during installation, unclean working environment of bearings, and pollution of working media.


  1. It is best not to disassemble the bearings before using them.
  2. Keep the installation environment clean during installation.
  3. Cleaning of bearings to be used.
  4. Sealing device for reinforced bearing.


Fatigue damage is a common damage mode of bearings. Common causes of fatigue damage may be long-term overload operation of bearings, not timely maintenance, improper maintenance, equipment aging and so on.

Suggestion: choose suitable bearing type and replace fatigue bearing regularly.

Above are the most common reasons for early damage of bearings.
