Bucket elevator is a mechanical conveying equipment with a fixed device. It is mainly suitable for continuous vertical lifting of powdery, granular and small pieces of materials. It can be widely used in various scales of feed mills, flour mills, rice mills, oil mills, etc. The lifting of bulk materials in factories, starch factories, grain depots, port terminals, etc.
The bucket elevator is used to vertically lift limestone, coal, gypsum, clinker, dry clay and other bulk granular materials and raw meal, cement, coal powder and other powdery materials passing through the crusher. According to the speed of the hopper, the bucket elevator can be divided into three types: centrifugal unloading, gravity unloading and mixed unloading. Centrifugal unloading has a fast bucket speed, which is suitable for conveying powdery, granular, small lumps and other materials with low abrasiveness; gravity unloading has a slow bucket speed, which is suitable for conveying lumpy and large specific gravity materials. , abrasive materials, such as limestone, clinker, etc. The traction components of the bucket elevator include ring chains, plate chains and belts. The structure and manufacture of the ring chain are relatively simple, and the connection with the hopper is also very firm. When conveying abrasive materials, the wear of the chain is relatively small, but its own weight is relatively large. The structure of the plate chain is relatively strong, and its weight is light. It is suitable for hoists with large lifting capacity, but the hinged joints are easy to be worn. The structure of the belt is relatively simple, but it is not suitable for conveying abrasive materials. The temperature of ordinary belt materials does not exceed 60 ℃, the steel rope belt allows the temperature of the material to reach 80°C, the heat-resistant tape allows the material temperature to reach 120°C, and the temperature of the material conveyed by the ring chain and plate chain can reach 250°C.
