What C-Mac's customer says about our Bulk Bagger/Bulk Bag Filling Hopper

"Our old bagging hopper was a pain and we had been putting up with it long enough, saw  C-Macs hopper on the internet which resulted in a visit, it was time to do something so we put it on the back of the truck and brought it back to the yard.

We have tripled our production filling about 20 bulk bags per hour. It’s easily moved to different sand bunkers, easy to wash ready for the next product. It’s perfect, we have now taken on more orders."
