Increased Asphalt Production
The Value of a Griffin Baghouse
One of our neighbors here in Syracuse, an asphalt producer, contacted Griffin Environmental with a problem. The asphalt plant was a Barber Green built in 1971, in operation for 4 years in New Jersey then moved to Syracuse in 1975. It was undersized and could not produce at the capacity needed in a reasonable time. Trucks waited up to 2? hours for each new batch of product. The problem was particularly urgent since the business had grown substantially.
Griffin application engineers determined that the current system could be retrofitted with a JA-462-CE. They were able to use the existing hopper, support legs and ductwork. The number and length of bags were increased to bring the air flow from 28,000 ACFM to 37,000 ACFM. A pulse jet cleaning method replaced the plenum pulse. In upgrading the production line, the owner also installed new screens.
The new system went on line in June 1990 and it was soon evident that the upgrade was well worth the effort and expense. Since starting up with the new baghouse, the customer realized a 33% increase in production which allowed him to accomplish in 8 hours what had taken 10 hours!
- Since there are no moving parts, there is less maintenance.
- Less compressed air is used for the cleaning cycle.
- The smaller blower (from 125hp to 100hp) uses less electricity.
- Increased efficiency means less fuel to heat the product.
After 10 years in operation, the system is still running at peak performance. There are many small, independent asphalt plants that could benefit from a similar retrofit and Griffin engineers welcome the challenge.
