I would like to know how other moulding manufacturers handle removal of wood chips. We have to transport about 15 cubic yards per day. We presently use dump trailers and a horse farmer takes it. The problem is coordination of the pickup schedule. Does anyone know of any bailing/crushing system that is not too manual?

From contributor D:
We contracted with a fellow that collected the shavings and sold them to horse farmers in the area ($115.00 for a stake truck load, delivered). We let him have the shavings as long as he kept us cleaned out - we did not have to stop or deal with the shavings in any way.
Problems arose since his cocktail hour started at about 8:00 am, and there were days when he wouldn't show, and we would risk a backup (shut down and shovel for about 1-1/2 hours). The problem was solved by installing a large silo - 10' diameter x 18' high - with a Flying Dutchman inside to knock down bridging shavings, and an auger to unload. This worked well until he left the Dutchman running as he drove away. A bearing burned up, sent smoke to the smoke detectors and we had a big response to almost no fire. We put the Dutchman/auger on a key switch and a timer so it would run for no more than 15 minutes.
Sidebar: When the fire happened, I contacted the other two shops that this guy hauled for and warned them, and explained our solution. The "big guy" laughed and said that could never happen. 3 months later, the manual switch on the shaker grate was left on, a bearing overheated, and their whole dust collection system went up.
Contributor D, please explain how your Flying Dutchman actually works.
The silo is a grain silo, and the Flying Dutchman (brand name) is a center mounted revolving pole with chains hanging off of it. The motor hangs below the pole, outside of the conical floor of the silo. A grain auger - 8" in our case - also feeds from the bottom of the conical floor. When the Dutchman was turned on, it would revolve (about 60 rpm) and knock down the shavings that would bridge and stop flow down to the auger. It all worked fine, but was a sizeable investment. We never saw shavings or had to deal with them as a result. This is all farm tech, since we are located in the middle of the Corn Belt.
