A screw conveyor usually consists of a driving device, a head section, a middle section, a tail section, a head and tail bearing, and a feeding and discharging device. If conditions permit, the driving device is placed at the discharge end. It is reasonable to install the feed port in the head section (with thrust bearing assembly), so that the screw can be in a tensioned state. Each of the head, middle, and tail sections has several different lengths. The arrangement order of each spiral section follows the principle of sequentially arranging the length of the spiral sections and arranging the spiral sections of the same specification together. The installation starts from the head and proceeds sequentially. In the overall arrangement, care should also be taken not to place the base and the discharge port at the flange of the housing joint, and the inlet should not be arranged above the hanging bearing.
LS type screw conveyor is designed and manufactured according to JB / T679-95 "Screw Conveyor " standard, and it is the replacement product of GX type screw conveyor.
The head and tail bearings are moved to the outside of the housing. The hanging bearings are sliding bearings without dust seals. The bearing pads are generally powder metallurgy. The cement is conveyed with felt bearings. The hanging shaft and screw shaft are connected to the slider. The driving device does not need to move the screw when removing the hanging bearing, and the hanging bearing can be lubricated without removing the cover plate. The whole machine has high reliability, long life, strong adaptability, and convenient installation and maintenance.
