Screening Bucket
Screening buckets are installed on general construction machinery (host), such as excavators and loaders. Using the hydraulic power of the host machine, the rollers of the bucket are controlled by operating the foot valve. The roller rotates in both forward and reverse directions to crush, mix and stir the materials in the bucket. The mixed materials fall under the action of the roller and the weight of the materials. The loading process of materials by screening bucket is the same as that of ordinary bucket. If the roller does not move, the materials will not fall.
Motek coarse screening have 45mm and 75mm gaps for each series.
Customers can choose products with different gaps according to the construction site conditions.
