The trough type screw conveyor is designed and manufactured according to the JB/T7679-95 "Screw Conveyor" standard, and is a replacement product of the GX type screw conveyor. The head and tail bearings are moved outside the shell, and the suspension bearings are made of sliding bearings with dust-proof sealing devices. The bearing shells are generally made of powder metallurgy. Felt bearing shells are used for conveying cement. The suspension shaft and spiral shaft are connected by sliding blocks. When disassembling the spiral, the driving device does not need to be moved, and when disassembling the suspension bearings, the spiral does not need to be moved. The cover plate can lubricate the suspension bearings without disassembling. The overall performance is high, the service life is long, the adaptability is strong, and the installation and maintenance are convenient.

The groove type screw conveyor is the main unit for mechanized transportation in various sectors of industry and agriculture, which can reduce labor intensity and improve work efficiency in transportation work, and has a wide range of applications. Suitable for various industries, such as building materials, chemical industry, power, metallurgy, coal, grain, etc. It is suitable for horizontal or inclined transportation of powdery, granular and small block materials, such as coal, ash, slag, cement, grain, etc., with material temperature less than 200 ℃. Spiral machines are not suitable for conveying materials that are prone to deterioration, high viscosity, and clumping.
