RAY crushing and screening bucket is one of the attachments for excavators/loaders. It uses the hydraulic power of the host to control the rollers of the bucket by operating the foot valve. The rollers rotate in both forward and reverse directions. The material in the bucket is crushed, mixed and stirred, and the mixed material falls down under the action of the roller and the weight of the material. The loading process of the screening and crushing bucket is the same as that of the ordinary bucket. If the roller does not move, the material will not fall. It integrates screening, crushing, mixing, gas explosion and loading.
