Hoists generally refer to large-scale mechanical equipment with large power and strong lifting capacity. It is used to vertically lift limestone and other block granular materials that have passed through the crusher, as well as powdered materials such as raw materials, cement, and coal powder. According to the speed of the bucket, bucket elevators can be divided into three types: centrifugal unloading has a faster bucket speed and is suitable for conveying powdery, granular, small block materials with low abrasiveness; gravity unloading has a slower bucket speed and is suitable for conveying blocky, heavy, and abrasive materials, such as limestone and clinker.
