[0002] Usually after the ore is mined, there will be some smaller crushed stones mixed in the ore. These crushed stones mixed in the ore will affect the subsequent refining and processing of the ore. Therefore, the crushed stones need to be filtered and screened out after the ore is mined; the screening bucket is a multifunctional auxiliary tool for engineering machinery, which can be installed on excavators, loaders or skid loaders. The use of screening and crushing buckets can complete the screening, crushing, aeration, mixing, separation, feeding and loading of solid materials in one step. It is widely used in the fields of mining and quarrying due to its advantages of simple feeding method and high screening efficiency.
