    摘要: An edge plate 11 of prescribed height is provided around three sides except a free end side of a swinging plate 5 that can close the lower end of an ore fines inlet pipe 2 which is tilted at a prescribed angle. By the edge plate 11 of prescribed height, when the swinging plate 5 is opened, the ore fines are allowed to flow out only from the free end side of the swinging plate 5 provided that the opening height is held within the height of the edge plate 11, and an accurate flow control of ore fines can thus be achieved.

    摘要: 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.

    摘要: A fastening bolt fastens flanges between a bolt head and a nut attached on the threaded portion of the shaft via spherical washers. The fastening bolt has a cavity formed within the shaft. By application of pressure in the cavity with a hydraulic fluid supplied through a hydraulic pressure port in a plug, the shaft is extended and the fastening bolt becomes unfastened condition. In the unfastened condition, a gap is created between flange and nut, and the nut and the fastening bolt are free to rotate each other, therefore, the nut can be removed easily by hand from the fastening bolt, even the bolt is large in size. The fastening force is adjustable by the width of the gap before releasing hydraulic pressure in the cavity. By releasing hydraulic pressure in the cavity, the fastened condition is obtained. Conversion between fastened condition and unfastened condition can be made quickly and easily.

    摘要翻译: 紧固螺栓通过球形垫圈将法兰紧固在螺栓头和连接在轴的螺纹部分上的螺母之间。 紧固螺栓具有形成在轴内的空腔。 通过在通过插头中的液压端口供应的液压流体在腔中施加压力,轴被延伸并且紧固螺栓变得松开状态。 在松开状态下,法兰和螺母之间产生间隙,螺母和紧固螺栓自由旋转,因此螺母可以用手从紧固螺栓上轻松取下,即使螺栓尺寸较大 。 在释放空腔内的液压之前,紧固力可以通过间隙的宽度来调节。 通过释放空腔中的液压,获得紧固状态。 紧固状态和松开状态之间的转换可以快速方便地进行。
