Automatic batching system.
An eight-ingredient rubber compounding system for specially engineered rubber products is described in a one-page, four-color bulletin. The system consists of eight two-module vibratory feeder systems with an upper mass flow and lower trim or dribble feeder. The feeders are designed to feed directly into two individual net weigh hoppers with a designed weigh scale accuracy of [+ or -] .002 lbs. Final batch accuracy attained was [+ or -] .005 lbs. Feeder supply hoppers feature a three to five cubic foot capacity. Discharge gates on the weigh hopper are of a specially designed miniature clamshell design for total cleanout, according to the literature. (Bulk Equipment Systems Technology)
