product news/產品新聞 Te abrasive falls onto a perforated plate or sieve, which
separates the coarse parts. Tis perforated plate must be checked and cleared regularly in order to prevent abrasive accumulation. Shot blasting machines from AGTOS, Emsdetten,
Germany, can be adjusted in the windsifter section, making it possible to control the air speed. Small particles can be extracted with a lesser air stream than larger particles. An additional sliding plate enables the windsifter to
adjust to different slipping properties of the abrasive. Another possibility for the separation of fine and coarse
particles is the blade, which cuts the abrasive veil, improving the extraction of undersize particles. An adjustable counterweight regulates the backpres-
ties are utilized. ■ Visit

sure of the abrasive before the discharge edge, producing an even abrasive veil. In order to control and adjust all these possibilities during operation, AGTOS machines provide a control window that may be opened for adjustments for short periods during operation. Further measures can reduce the fines in the abrasive. One method is always to include the bucket elevator head in the suction system because material accumulates there due to the movement of the abrasive discharged from the buckets to the sliding plate of the purifying unit. AGTOS also offers its customers a depression gauge that enables the control of the negative pressure in the abrasive sifter from the switchboard or the control room. In the case of older blasting wheel shot blasting ma- chines, users should check whether all adjustment possibili-
磨料落到一个孔板或筛网上，粗大部分被分离 出去。孔板须定时检查清理，以免磨料堆积。德国 Emsdetten的AGTOS公司的抛丸机可以调整风筛部 分，使得风速可调。细微颗粒可以用小一些的气流来 提取。
额外增加一个滑板，使得风筛可以针对不同流动性 的磨料进行调整。
一个可调的平衡砝码可以调整磨料卸出之前的背 压，平衡磨料的覆盖面。为了在操作中控制调整这些 参数，AGTOS公司的设备提供了一个控制窗口，可 以在操作时打开，作短时调整。
进一步措施可以降低磨料中的微粒。一个基本方法 就是将斗式提升机头纳入吸取系统，因为磨料从斗中 卸出到提纯单元的滑板中时会在那里集聚。AGTOS 给客户提供一个压力表，使得客户可以在控制室中通 过控制面板来控制磨料筛中的负压。 对于磨料净化单元的大量优化方案已经表明了这 对抛丸过程质量和维护时间及成本的重要性。对于老 式的转子抛丸机，用户需要检查是否所有的调整都可 用。■
