Carbon steel screw conveyor U-type shaftless dry powder feeder Tubular high-temperature resistant hoist
screw conveyor has a novel structure. The head and tail bearings are moved to the outside of the shell. The middle hanging bearing adopts two structures that can be interchanged by rolling and sliding. Both are equipped with dustproof sealing devices. The discharge end is equipped with a cleaning device. The whole machine has low noise, strong adaptability, convenient operation and maintenance, and flexible layout of the inlet and outlet.
Scope of Application
screw conveyor is widely used in various industrial sectors, such as building materials, electric power, chemical industry, metallurgy, coal, aluminum and magnesium, machinery, light industry, grain and food industry;
spiral conveyor is suitable for conveying powdery, granular and small materials, such as cement, pulverized coal, grain, fertilizer, ash, sand, etc., with a horizontal or less than 20 ° inclination, and the material temperature is below 200 ℃.
Matters Needing Attention
The screw machine is not suitable for conveying materials that are easy to deteriorate, sticky and caking, because these materials will stick to the screw during transportation, and then rotate without moving forward or form material accumulation at the lifting bearing, which makes the screw machine unable to work normally.
Selection Instructions
The screw diameter ranges from 200 mm to 500 mm, and there are five specifications in total. The length ranges from 4 m to 70 m, with a gear every 0.5 m. The selection conforms to the standard nominal length, and special requirements can be separately proposed in the selection section.
