Self-Governing Floor Apron and Feed Roller

The hammermill is fed by a self-governing floor apron and feed roller through a 61-1/2” (156.2 cm) wide by 35” (88.9 cm) high feed opening. The programmable logic speed control (PLC) governs the product flow through the 13’ 2” (4.01 m) 197 cu. ft. (5.59 cu m) feed hopper for maximum grinding efficiencies.

Four Hydraulic Stabilizer Legs

The 7064 is equipped with four hydraulic stabilizer legs to provide a rock-steady platform while grinding.
