Abstract
A granular material supply system has a granular material supply unit and a granular material feed unit. The granular material supply unit delivers a granular material through an inlet formed in a pressure case included in the granular material feed unit onto a conveying device disposed in the pressure case. The conveying device conveys the granular material to an outlet formed in the pressure case to feed the granular material through the outlet into a granular material using apparatus. The granular material supply unit, and the pressure case of the granular material feed unit can be immovably installed. Therefore the granular material supply system can be formed in a closed system without placing any special joints, such as expansion joints, in a line connecting the granular material supply unit and the pressure case and in a line connecting the pressure case and the granular material using apparatus. Only the conveying device needs to be disposed in the pressure case. Thus the granular material supply system is very simple and small in construction and is not very tall, which is advantageous in space for installation and equipment investment.
