^{Our company's research and developmentCoarse particle WLS shaftless screw conveyorNot only can it achieve horizontal material transportation, but it can also tilt transportation. It can also be suspended, ground mounted, mixed suspended, mobile, or rotatable around the feed inlet axis according to customer requirements. The conveying distance can also vary according to work requirements, generally ranging from 2-20m.The shaftless screw conveyor can transport materials that traditional shaft screw conveyors and belt conveyors cannot or are difficult to transport, such as granular and powdery materials, wet and paste materials, semi fluid and viscous materials, materials that are prone to entanglement and blockage, and materials with special hygiene requirements.}

^{Coarse particle WLS shaftless screw conveyorIt is driven by an electric motor to operate the cycloidal reducer, which is driven by the mechanical seal shaft and the connecting disk on the shaftless spiral body to rotate the screw. When the sludge is discharged to the feeding port at the upper part of the U-shaped groove, it is discharged through the discharge port at the lower part of the U-shaped groove through the spiral transmission. In work, sludge is like a stationary nut, while a shaftless screw is like a rotating bolt. Continuous rotation of the bolt can drive the nut from one end to the other. A horizontally installed shaftless screw conveyor can simultaneously collect sludge processed by two filter presses and one centrifuge, and transport it to the next process.}

^{Compared with belt conveyors, shaftless screw conveyors have the following characteristics:}

^{(1) Due to the use of stainless steel for U-shaped grooves, legs, cover plates, and other components, the appearance is beautiful, the structure is compact, and the footprint is small.}

^{(2) The overall structure is relatively simple with few components. The U-shaped groove adopts a segmented flange connection, which facilitates the replacement and maintenance of the internal lining, thus ensuring safe and reliable operation of the whole machine and easy maintenance. Due to the high wear resistance of the shaftless spiral body and U-shaped groove protective liner materials that experience friction, coupled with the low rotation speed of the spiral, the wear is small, the service life is long, and the maintenance cost is low.}

^{(3) If the dehydrated sludge accidentally falls into the feed inlet, it will not cause scattering or leakage, and will not pollute the environment. In addition, due to the cover plate installed on the upper part of the U-shaped groove, the transportation process is basically enclosed, which can effectively reduce indoor odors.}

^{(4) During normal operation, there is basically no need for maintenance or adjustment, which can effectively reduce the labor intensity of operators}.
