2019-04-11 15:29:03 Hello everyone! I’m the editor of the Mechanical Technology Department. What kind of elevator is used for powdered materials today? I will introduce two high-efficiency powdered material lifting equipment. 1. Powdered material vertical spiral elevator, powdered material vertical spiral elevator is used for Convey materials horizontally, obliquely or short distances. It also has a stirring function while lifting, and it can feed and discharge materials at multiple points. The centrifugal force generated by the vertical spiral belt in the vertical spiral elevator for powdered materials rotates at high speed and pushes the powdered materials to the tube wall, and then is pushed up by the blades. Its lifting height is within 20 meters. The spiral shaft in the tube is equipped with spiral blades, and the casing is supported on rollers for low-speed rotation, and the powder moves forward along the blades, thereby lifting the powder to the discharge port, and loading and unloading are carried out at both ends. It can convey the powder material at a slight incline without jamming, and can avoid the damage to the powder material. It also has good airtightness, no dust leakage and low noise, which is suitable for occasions where a relatively quiet working environment is required. The structure is simple and easy to maintain. The energy consumption is small, the use cost is low. It can be directly connected and fixed with the supporting equipment, does not require a foundation, and makes full use of the site space. However, it is not suitable to transport powders with high hardness, easy deterioration, high viscosity, and easy agglomeration. Reduce wear and avoid the occurrence of screw machine jams! 2. Powdery material bucket elevator Powdery material bucket elevator is a kind of fixed mechanical conveying equipment, which can adjust the height and conveying speed of the elevator according to the conveying volume. Bucket elevators for powdered materials are generally equipped with two parallel parallel chains with a pair of drive sprockets on them. The hopper scoops up the material from the storage below. As the loading conveyor
belt or chain is lifted to the top, it turns over after bypassing the top wheel, and the material hoist pours the material into the receiving tank to achieve the purpose of lifting. According to the speed of the hopper, the bucket elevator for powdery materials can be divided into three types: centrifugal discharge, gravity discharge and mixed discharge. The centrifugal unloading hopper has a faster speed and is suitable for conveying powdery, granular, small lumps and other materials with low abrasion properties; the gravity unloading hopper has a slower speed and is suitable for conveying lumpy and larger specific gravity materials. , The material with great abrasiveness. The powder material bucket elevator has the advantages of large conveying capacity, high lifting height, stable and reliable operation and long service life. It can continuously lift operations, but the conveying temperature should not exceed 250 degrees. If the conveying medium has a low melting point, the temperature of the conveying powder is It should be lowered appropriately! The above is the two powder material hoists introduced by the editor. Please choose the hoist equipment reasonably according to the characteristics of the material, the number of meshes, the output, and the required accuracy.
looking for the best deal while getting a quality is usually the number-one objective for most container loading machine manufacturer.
