This shaftless screw conveyor  overview:

 LI type screw conveyor commonly known as the ground dragon, is mineral, feed, grain and oil, construction of a widely use of a continuous conveying equipment, it use rotate spiral sent material along the fixed cabinet goes on, the situation is like stuck nuts when screw rotate, can only be along the screw translation sports, and cause material does not rotate together and spiral of force is the material of the gravity of the cabinet and friction. From the point of view of displacement direction conveyed material division, screw conveyor is divided into level     screw conveyer equipment and vertical type spiral conveyer equipment two types, mainly used for all kinds of powder, granule and loose materials such as small block the level of vertical transportation and ascension, this screw conveyor not suitable for conveying easy metamorphism, big viscosity, easy to agglomerate or high temperature, afraid of the pressure, and has a larger corrosive special materials.

Product features:

1. the structure is simple, safe and convenient operation.

2. the small size, high speed, ensure rapid uniform transmission. The appearance of cross-sectional size is not big, easy in several positions and unloading, the cabinet of a lid can achieve good seal. But unit power consumption is high, the operation of the material is susceptible to pieces, and sensitive to overload, equally of feeding, spiral, chassis and hang bearing severe wear.

3.good sealing, the shell is made of the seamless steel tube, the end part use flange connection as a body, good rigidity.

4.Applicant:This machine can be widely used in chemical industry, building materials, machinery, coal, metallurgy, light industry, food, medicine, transportation, water and electricity, and other departments, used to convey various kinds of powder and small piece of material. Such as: coal, cement, sand, coal, grain, etc. But the power consumption, so much for low or medium productivity, the transmission distance not longer, unfavorable to big viscosity of metamorphic conveying the agglomeration of material or large materials. This machine is allowed to use slightly tilted installation, the maximum gradient: less or equal to 20 °, working environment temperature:-20 °C to 50 °C

5. The temperature of the conveying material: less than 200 °C.
