系统特点

Characteristics

　　1.适应物料范围宽，大到100mm的物料，耐高温耐腐蚀性强。

　　2.独特的防卡料技术。独特的结构设计，使得轮辐转子在围绕轴心转动的同时，还可以上下和水平滑动，自动清除卡住的物料或异物。同时，轮辐转子连同耐磨墙一起旋转，有效减少了壳体的磨损和避免了转子与壳体间隙的卡料。

　　3.密封与耐高温技术。本设备轴承保护采用气封降温+耐高温毛毡密封+多层密封支架结构的方式，有效地阻止高温物料侵蚀轴承。同时，高温物料只和转子与密封板接触，轴承、计量、驱动等部件置于密封壳体之外，大大延长了设备使用寿命。

　　4.布置安装简单，占用空间小，便于维护。

1. It's suitable for materials of different sizes up to 100mm, with good corrosion resistance and high-temperature resistance. 2. It possesses special anti-blockage technology, to allow the spoke rotor to rotate around its axis and slide meanwhile vertically and horizontally, which make the stuck materials or foreign materials to be removed automatically. Besides, the wear resistant wall, connected with spoke rotor, rotates together, avoiding effectively the wear and material blockage between spoke rotor and housing wall. 3. It adopts sealing and high temperature resistance technology. The structure of bearing is: air seal (to reduce the temperature) + high-temperature resistant felt seal + multilayer sealed support, so as to efficiently prevent materials and impurities from entering the bearing. Meanwhile, the high temperature material is only in contact with the rotor and sealing plate and components such as bearing, metering and driving parts are laid outside the sealing housing, thus prolonging the service life of equipment. 4. The installation is simple, the space occupied is limited and the maintenance is easy
