Pellet sticking to the wall is the most common problem in new type ywo in one organic fertilizer granaultor. It's mainly caused by raw material moisture content, viscosity, and mismatch between equipment structure and operating parameters. The following methods can quickly resolve this issue.

First, control the moisture content of the raw material, as this is the most crucial factor. The moisture content of organic fertilizer raw materials is generally controlled between 30% and 40%. Excessive moisture easily leads to sticking. Adding appropriate amounts of straw powder, peat moss, or dry organic fertilizer powder can adjust the moisture content and reduce material viscosity, thus reducing sticking at the source.

Second, check and replace the internal scraper. The granulator's inner wall is equipped with a dedicated scraper. If the scraper is worn, loose, or at an incorrect angle, it cannot scrape off the sticky material in time, causing it to accumulate. Adjust the gap between the scraper and the inner wall to ensure a tight fit. Replace severely worn scrapers directly.

Then, adjust the rotation speed and feed rate appropriately. Too slow a rotation speed results in long material residence time and sticking to the wall, while too fast a speed leads to unstable pellets. Feeding should be uniform and continuous to avoid large amounts of material being fed at once, causing localized material accumulation and sticking to the wall. Increasing the rotation speed appropriately based on the viscosity of the raw material can effectively reduce adhesion.

Regularly clean the inner wall of the fertilizer making machine. After each production run, promptly rinse or remove any residual material lumps to prevent them from hardening and forming scale, which would make subsequent materials more prone to adhesion. Over time, a rough inner wall can also cause material buildup; polishing the inner wall can improve its smoothness.

Additionally, appropriate amounts of auxiliary materials can be added. For particularly viscous manure-type raw materials, small amounts of inert powders such as fly ash, diatomaceous earth, and talc can be added to reduce adhesion. Simultaneously, ensure uniform fineness in the initial crushing process to prevent large pieces of wet material from directly entering the granulator.
