Classification of screw conveyors

(1) The GX fixed screw machine is a fixed product of the mechanical department and has been used for decades.

(2) LS-type screw conveyor adopts international standard products, adopts ISO1050-75 standard, and is designed and manufactured in accordance with the professional standard of ZB/T7699-45 "LS-type screw conveyor". Its structure is novel, and the head and tail bearing are moved outside the shell. The middle suspending bearing adopts two structures that can be interchanged by rolling and sliding. No dustproof sealing device is provided. Nylon and plastics are used as seals. The resistance is small, the sealing is strong, and the wear resistance is good. The sliding tile needs to be lubricated. Cast copper tiles, alloy wear-resistant iron tiles and copper-based graphite less oil sobbing shoes, equipped with a cleaning device at the discharge end, the location of the inlet and outlet is flexible.

Divided into the following according to the type of screw machine middle suspension bearings:

M1-Roller-bearing bearings adopt 80000-type sealed bearings. There is a dust-proof sealing structure on the shaft cover. It is commonly used in areas where it is difficult to refuel, refuel, or oil contaminates the material. The sealing effect is good, the bearing life is long, and the temperature of the conveyed material is not Greater than 80 degrees Celsius.

M2-sliding bearings are equipped with dust sealing devices. Oil-bearing materials include cast copper tiles, alloy wear-resistant cast iron, and copper-based graphite less oil-lubricated tiles. They are commonly used for conveying materials and have relatively high temperatures.
