Description

The material to be milled is placed between the feed and center rolls. Each adjacent roll rotates at progressively higher speeds. For example; the feed roll may rotate at 30 rpm, the center roll at 90 rpm and the apron roll at 270 rpm. Material is transferred from the center roll to the apron roll by adhesion. The dispersion is achieved by the shear forces generated between the adjacent rolls. The milled material is removed from the apron roll by a knife that runs against the roll. • 1/2 HP through 15 HP • Driven by a TEFC 230/460V, 3 Ph, 60 Hz, inverter-duty motor • 21 /2” x 5” model: stainless steel type 440C hardened precision ground rolls with adjustable Tefl on endplates • Production models: carbon steel type 52100 hardened precision ground rolls with adjustable bronze endplates • Stainless steel type 304 apron • Rolls are cored to allow water cooling or heating • All non-stainless steel external surfaces coated with a white two-part epoxy paint • Safety trip switch across the top of the mill AVAILABLE OPTIONS: • Stainless steel type 440C hardened rolls and Tefl on end plates for production models • Aluminum oxide, chromium oxide or tungsten carbide coating on rolls • Hydraulic roll pressure indicating devices • Explosion-proof, stainless steel or washdown-duty motor • NEMA 12 Operator Panel with variable frequency drive, Start/Stop pushbuttons, speed potentiometer, Emergency Stop button, forward/reverse selector switch and on/off switch for wash mode.
