We also have an adjustable anvil on our HG4000, as well as our HG6800, where we can move that as close as an eighth of an inch to those blades. That way, we can either have a small bite or work all the way up to a big bite.” Vermeer’s units also offer operators a wide range of screens. “You can have anywhere from rounds, squares, hexes, elongated, diamonds,” Shannon says. The second generation of the HG4000 also has offers new features for operators. “We moved from an FPT Fiat engine to a CAT C13B,” Shannon says. “This en-gine is going to produce at 536 horsepow-er for 50 per cent of its torque curve life. So, from a longevity standpoint, and from a warranty standpoint, this engine really performs very well.” Vermeer has set up the HG4000 with the company’s new droop feature. “With the traditional grinder you set your droop setting, or your RPM setting, how aggres-sive you want the machine to be. And as materials coming through, those RPMs are bogging down depending on how hard the material is coming through. And a lot of times those old machines, when that RPM drops down below that droop lev-el, it’s taken a lot for that engine to kick back into groove and get back above that droop,” Shannon explains. “It’s more of a predictive setting. It’s constantly keep-ing that RPM level and its torque curve to stay upon that droop low. That way, that engine is not having to take those huge dips in RPM and stay more efficient,” Shannon says. CBI CBI displayed the third iteration of its 6800 horizontal grinder, the 6800CT, at the show. The 6800CT has the option of a CAT C27 1,050-hp engine or a CAT C32 1,125 hp or 1,200 hp engine. “It’s the first of our 6800 series grind -ers to be able to accept 1,200 horsepower. We’ve upgraded a lot of the components to handle the extra horsepower. We’ve got bigger bearings, we’ve got a larger diam-eter shaft, and that’s what allows us to put the extra horsepower on the same chas-sis,” explains Jonathan Gilmour, regional sales manager for CBI. The 6800CT version had the hog box opened up with a split hog box design, which allows for easier access to the ro-tor, the mill and for the changing of wear parts. Gilmour says the design also allows SPRING 2023 14 Canadian BIOMASS 2023-03-16 2:20 PM CFI_Brunette_MarApr23_CSA.indd 1
