YCD-HG-type star discharge output used in pneumatic systems, for pressure or vacuum output system output system, star discharge can be uniformly and continuously fed to the conveying pipe, in order to ensure air pneumatic output tube Solid relatively stable, so that the pneumatic conveying can work, at the same time, but the upper and lower discharge pressure off the air lock and play the role. Therefore, star discharge is an important component of pneumatic conveying systems commonly used. First, the working principle of the star stripper known as rotary feeder, off the wind, is rotated by the rotor with several blades within a cylindrical enclosure, the material from falling into the upper part of the hopper, stuffed in between the blades within the space, with rotating blades and unloading. The star unloader, the next flanged base is square or round, can also be selected by the user. The wear-resistant closed rotor wheel type star discharge characteristics of the end portion of the rotor blade polyfluoroethylene lined sealing strip, the ends of the blades to ensure good contact with the inner wall of the housing, and can be easily adjusted after the wear of the blade tip portion , it still maintain good contact with the inside of the housing, the air lock has better performance. Temperature and type of material it transported temperature up to 280 degrees at both ends of the bearing and impeller has a certain isolation, ultra-fine powder to prevent contact with the bearing. Temperature heat unloader transport of materials up to 500 degrees, using sprocket connected, and unloading gear housing a certain distance. Second, the performance advantages and features a high YCD-HG-type star discharge machining precision, air lock function can be used to crush, powder feeder quantitative grading system, but also as a separation, dust collection systems, such as discharge, or for Pressure feed, suction-type pneumatic conveying systems. 2, with a pressure balance device, available in positive, negative transport system. 3, can be cast iron, steel, stainless steel, titanium, steel and other materials, flanged structure for a variety of forms, such as a square or circle, to meet the different needs of users.
