喷浆机是矿山巷道开拓掘进时的主要常用设备之一。喷浆机中的扇形摩擦片和旋转材板是易损件,寿命短,更换时费时费力并且设备维修费用大。扇形摩擦片现在大都采用耐磨工程塑料聚氨酯制作,效果较好。而旋转衬板至今未见有关改进的报道,仍然使用耐磨铸钢或铸铁材板。因此,作
Shotcrete machine is mine roadway pioneering one of the major commonly used equipment. The fan-shaped friction plates and rotating plates in the shotcrete machine are wearing parts with short life, time-consuming replacement and large equipment maintenance costs. Fan-shaped friction plates are now mostly made of wear-resistant engineering plastics made of polyurethane, the effect is better. The revolving lining has so far not been reported on the improvement, still use wear-resistant cast steel or cast iron plate. So, make
