Screw conveyor in the conveying form into a shaft screw conveyor and shaftless screw conveyor, on the exterior is divided into U tube and screw conveyor and screw conveyor. A shaft screw conveyor is suitable for the non-adhesive powder material and small particle material. (such as cement, fly ash, lime, food, etc.) without shaft screw conveyor is suitable for the material conveyor by viscous and winding. (e.g., sludge, biomass, waste, etc.) the working principle of screw conveyor is rotating spiral blade for screw conveyor conveying the material goes on, the material is not spinning force with the blades of screw conveyor is its own weight and screw conveyor casing material friction resistance of the material. Screw conveyor on the axis of rotation welding of spiral vane, the face of the blade type according to the different type has a solid surface of conveying material, belt type, such as blade surface type. Screw conveyor screw axis of the terminal at the direction of material movement have thrust bearings to the material to spiral axial reaction force, the captain is longer, should add hanging bearing in the middle.
Type LS/GX screw conveyor main characteristics
1, large carrying capacity, safe and reliable.
2, strong adaptability, easy installation and maintenance, long service life.
3, the machine is small in size, high speed, ensure rapid delivery uniformity.
4, the discharge end is equipped with cleaning device, low noise, strong adaptability, in and out of the mouth position arranged flexibly.
5, good sealing, shell made of seamless steel tube end use flange connection each other as a body, good rigidity.
The working principle of the LS/GX type screw conveyor
Type LS screw conveyor is the use of rotating screw within the casing materials will be transported along a fixed time and delivery work, head and tail bearing to the shell, sliding bearing is equipped with dust-proof sealing device for the suspension bearing, bearing bush generally use of powder metallurgy, transport cement adopts the felt pad, hoisting shaft and propeller shaft connected by sliding block.
