Surge Hoppers for a Steady Feed
Surge hoppers are built to feed material into the RMT Hammermill at a steady rate, so the mill can do its job and produce the fine fiber your operation depends on. If the feed is uneven, your end product suffers. Available in two sizes: the 10-yard model runs a 7.5 hp motor with a 48″ rubber belt, and the 20-yard steps up to a 15 hp motor with drag chain for heavier material. Tell us what you’re running and we’ll spec the right hopper.
