The main causes of roller sticking in a double roller press granultor are as follows:
1. Raw material problems: Excessive moisture or oil in the raw material can cause the raw material to adhere to the roller surface, forming a sticky substance as the rollers rotate, which then adheres to the rollers.
2. Equipment problems: Insufficient roller surface roughness or wear prevents the raw material from being fully dispersed as it passes through the rollers, forming a sticky substance. During operation, the rollers may be too close or improperly adjusted, preventing the raw material from flowing smoothly, resulting in a sticky substance. Loading a new double roller press granulator directly without demolding it before use can also cause roller sticking.
Solutions:
1. Control the moisture and oil content of the raw material: Before processing, the moisture and oil content of the raw material should be controlled to prevent it from sticking to the roller surface.
2. Regular roller surface maintenance: Regularly maintain and service the roller surface to ensure smoothness and roughness, thereby reducing raw material sticking as it passes through the rollers.
3. Adjusting the Roller Spacing: Adjust the roller spacing of the double roller press granulator based on the raw material properties and the actual equipment conditions to ensure smooth material flow and minimize adhesion.
Adding an Anti-Stick Agent: Adding an appropriate amount of anti-stick agent to the raw material can effectively prevent the raw material from adhering to the roller surface, minimizing the likelihood of adhesion. The adhesive ratio should be appropriately adjusted based on the raw material properties and production requirements.
4. Demolding: New machines should be demolded before use to ensure proper operation of the organic fertilizer equipment.
