Session 6  •  Monday, November 2  •  3:00pm - 4:30pm

Sandwich belt high angle conveyors have found wide use in the marketplace along with recognition of substantial savings. The system can be found in varying applications and has demonstrable environmental benefits. Furthermore, sandwich conveyors are suitable for applications in chip handling and have proven that once the cost saving benefit is calculated, the phrase “money for nothing and chips for free” rings true.

The replacement of blowlines and low angle conveyor systems with the sandwich conveyor system allows for cost savings and the protection of money making commodities.

This presentation will explore the many benefits of using a sandwich belt conveyor for chip handling.
