振动混砂机是德国 Klein 公司的产品,用于芯砂的混制。是1978年德国亚琛(Aachen)工业大学伯尼兹(Boenisch)教授的发明专利。振动混砂机的特点是砂的混合采用振动方式,而不象一般混砂机果用叶片方式,没有旋转部件,因而也就不存在叶片的磨损问题。振动混砂机的本体是一个圆筒,内面焊有固定的提升管和四块导向叶片,外部靠连接桥板和拉条把它与不平衡电机连接在一起,然后通过隔振器安装在底板上。来自不平衡电机的振动使混砂简中的砂从底部向提升管中上升, Vibrating Sand Mixer is a product of Klein GmbH of Germany for mixing sand core. Is the invention patent of Professor Boenisch of 1978 Aachen Industrial University in Germany. Vibrating sand mixer is characterized by mixing of sand using vibration, rather than the general method of sand mixer fruit leaves, there is no rotating parts, and therefore there is no blade wear problems. Vibrating sand mixer body is a cylinder, the inner surface of the welding fixed riser and four guide vanes, the external bridge and drawbar to connect it with the unbalanced motor, and then installed in the floor through the vibration isolator on. The vibration from the unbalanced motor raises sand in the sand from the bottom into the riser,
