Zinc Powder Conveyor System

This system is designed to convey zinc powder having a bulk density of 157 lb/cu ft at a controllable rate of up to 24 cu ft/hr. Material is loaded into the AFC Model #25R(HD)-25 (2½-in.-diam x 25 ft long) heavy-duty series conveyor via an 8.5 portable "Flow Free" surge hopper with 8-in.-diam flow control butterfly valve. The surge hopper is positioned directly above the AFC 8.5 True Flow hopper and connected via a flexible sleeve to insure a dust-tight interface. An exhaust sock is provided to address the air displacement during loading. The zinc powder is conveyed at a 45-degree angle to an elevation of 18 ft, 6 in. to an existing 60-in.-diam vibratory screener. A variable frequency drive is utilized to control the feed rate to the screener. The AFC True Flow hopper incorporates a low level switch and pneumatic vibrator.
