The ARMEX GHBF3620 Adjustable Hydraulic Feed Hopper Grizzly is a heavy-duty skid-mounted feed solution engineered for mining, quarrying, aggregate and recycling applications where consistent feed control and reliable oversize removal are critical to plant performance. Combining a 4.0 m³ surge hopper, a hydraulically adjustable grizzly and a 750 mm FB750 belt feeder, the GHBF3620 delivers controlled material feed to downstream equipment while protecting crushers and screens from damaging oversize material.
The grizzly angle is fully adjustable up to 20° via hydraulic actuation, allowing the operator to tune scalping performance to suit different material types and feed gradations without manual intervention. The 90–100 mm grizzly gap ensures efficient removal of oversize material, while the variable speed FB750 belt feeder delivers a regulated, steady feed at speeds between 1 and 9 m/min. Built on a robust structural steel base frame and finished with an industrial protective paint system, the GHBF3620 is ready to perform from day one in the most demanding African operating conditions.
