Product Description
What is a precleaner or primary belt cleaner?
Precleaners are belt cleaners that are designed to scrape material off the conveyor belt. Precleaners are mounted to the head pulley, below the material flow. They are ideal for removing large pieces of material - typically about 60-70 percent of initial carryback.
What is a secondary BELT cleaner?
Secondary cleaners are belt cleaners that are built to scrape materials left on the belt beyond the head pulley. Secondary cleaners are located just past where the belt leave the head pulley, and anywhere else down the beltline. Secondary cleaners are especially good at removing fines and can increase cleaning efficiency to more than 90 percent.
Features:
- Low friction coefficient is good in corrosion resistanc.
- Higher strength without damaging the belt, especially steel cord belt
- Flexibility and stiffness to adapt to belt profile
- Reach to food grade requirement, especial for food conveyor belt
- Fire retardant and anti static are available properties, especial for the mining industry
- Pre-slotted mounting holes reduce downtime and potential injury
Application:
Polyurethane scraper is commonly used in coal chemical conveyor belts for scraping off the attached ash and powder material. Such as the coal transportation, fertilizer transport, gravel transport and so on.
