The first and second belt cleaners each have advantages in different scenarios, so their usage frequency depends on the specific application environment.
First cleaner: usually installed in the head roller position, using a curved scraper to effectively remove belt residue without damaging the belt. Suitable for general industrial production environments, such as conveyor belts for transporting materials with larger particles and lower adhesion (such as ore, coal, sand, etc.). The structure of the First Cleaner is relatively simple, making it easy to use and maintain. Therefore, it is more commonly used in some conventional industrial scenarios.
Second Cleaner: Installed under the conveyor head wheel at the belt's straight working surface, used in conjunction with the first cleaning device. The scraper surface of the secondary cleaner is smooth, ensuring good contact between the scraper and the belt. It effectively removes belt adhesive without breaking or accumulating material, preventing scraper edge cracking and damage to the belt. Suitable for cleaning scenarios where dirt is heavy and requires more thorough attention. It can clean the ground or belts more deeply while ensuring cleanliness. Secondary Cleaners are divided into polyurethane secondary cleaners and alloy secondary cleaners. They have superior performance but are relatively complex in structure, requiring higher installation and maintenance requirements.
In summary, the first-stage cleaner is more commonly used in general industrial production environments, while the second-stage cleaner is more suitable for scenarios requiring more thorough cleaning. Choosing which type of cleaner depends on the specific usage needs and environmental conditions.
