The problem of ring die blockage in pellet machine is often a headache, but in fact there are many reasons behind this. Let's take a look at how to solve this problem!

1. The impact of compression ratio

The compression ratio, that is, the ratio of the inner diameter of the ring die and the aperture of the ring die, directly affects the pressing process of the particles and the working stability of the machine. If the compression ratio is set too high, the raw material may be overcompressed in the ring die, causing clogging. Therefore, it is crucial to find a suitable compression ratio.

2. Flowability of raw materials

Different raw materials have different adaptability to compression ratios. Some feedstocks may require a lower compression ratio to avoid clogging, while others require a higher compression ratio to obtain better particle mass. Understanding your raw material characteristics is key. Choosing the right compression ratio is the key.

3. Matching of device parameters

If the compression ratio of the ring die is not set properly, it does not match other parameters of the machine (such as feed speed, rotation speed, etc.), it may also lead to clogging. Ensure that the compression ratio matches other parameters, so as to ensure the normal operation of the machine.

4. Maintenance of ring dies

High compression ratio also requires higher wear and clogging of ring dies. Keeping the ring die clean and in good condition is the key to reducing clogging. Check and clean the ring die regularly to ensure it is in its best condition.

Hope these suggestions help you and make your pellet machine run smoother!
