Chute flow patterns are described and the application of chute flow dynamics to the determination of the most appropriate chute profiles to achieve optimum flow is illustrated. The influence of the flow properties and chute flow dynamics in selecting the required geometry to minimise chute and belt wear at the feed point will be highlighted. 1.

My first chipper - Wallenstein BX42S had trouble with the pitch from the needles/ green pines causing the discharge chute to plug. Solution - thin and pile the small pines. Let them dry for a year - then chip. Since I do this project almost every spring - this presented no problem. Letting them dry for a year was a solution.

Card Feed Chute: The feed weight at the card depends on the static pressure in the aero feed system and the chute depth adjusted. Since the pressure diminishes from one feed chute to another, the chute depth must be matched accordingly. It can be varied from 80 mm to 120 mm and is read off on the scale at the arrow mark. …

Even though it is a relatively minor wear part, the feed chute seal affects performance, lifecycle and safety in the SAG mill – and a failure can be disastrous in more ways than just time and money. One of the main issues with poor sealing between the SAG mill inlet chute and mill itself is the failure to retain water inside.
