What should I do if the mold of the rice husk granulator is blocked? In the production of rice husk granulator, mold blockage is a common problem, especially after replacing the new mold, in addition to the lack of manufacturing smoothness, there are many reasons that the new mold cannot produce particles. For example, the mold is left for a long time after purchase, and the surface of the mold hole is rusted; the thickness of the raw material does not match the mold hole; of course, it also includes mold blockage due to unskilled operation and other reasons.

What should I do if the mold of the rice husk granulator is blocked?

In the production of rice husk granulator, mold blockage is a common problem, especially after replacing the new mold, in addition to the lack of manufacturing smoothness, there are many reasons why the new mold cannot produce particles.

For example, the mold is left for a long time after purchase, and the surface of the mold hole is rusted; the thickness of the raw material does not match the mold hole; of course, it also includes mold blockage due to unskilled operation and other reasons.

The new die hole of the rice husk granulator has undergone a certain degree of finishing before leaving the factory, and the roughness is low, but oil is required to achieve the highest output. If you grind with oil (the ratio of sawdust, fine sand and waste oil is 4:4:2, and the new mold is ground for 20-30 minutes) before leaving the factory, the grinding time can be appropriately shortened or directly produced.

The trial run is generally fed with oil first, and after confirming that all the holes of the mold have been granulated (the granulating holes should reach more than 95%), the material is mixed with large friction, and the material is repeatedly extruded and circulated until the holes are worn away.

When the new mold is blocked, or the mold is not used for a long time, particles cannot be generated after reuse. The general method is to drill out the material with a drill bit or punch out with nails.

However, mold holes below 2.5 are not easy to handle. There are many disadvantages to drilling holes with a pistol. In this case, an oil-boiling stamping die may be used.

The specific method is: use iron to make an oil pan, put the waste oil, and then put the blocking mold into the oil; then heat the bottom of the oil pan until the material in the mold hole makes a cracking sound, and then take it out. Press the mold and reinstall it after cooling; after adjustment, start processing according to the original operation method, so that the material that originally blocked the mold hole can be quickly removed without damaging the original smoothness of the mold.

Generally speaking, the use of new mold parts in pellet factories should be purchased from professional manufacturers, which is of great benefit to users.

Some users do not purchase ring mold accessories from professional rice husk granulator manufacturers, process them themselves or solve them in the local market. The quality of these stampers is poor, the processing process is incomplete, and the surface hardness and geometric accuracy cannot be guaranteed. The use of these irregular stamping dies has a great impact on the main drive of the granulator itself, which can easily cause damage to the transmission parts, increase failures, and increase the maintenance cost of the entire machine, which is greater than the loss.
