LS serial screw conveyor

The LS series screw conveyor is a versatile continuous conveying device,which primarily relies on the rotation of the screw blade to push the material to flow.It is widely used in the conveying scenes of bulk materials in various industries such as agriculture,mining,building materials,and chemical industry.The structure of this series of equipment mainly consists of the driving device,screw shaft,blade,casing,inlets and outlets,and bearing components.It is arranged horizontally or slightly inclined(≤20°)and is suitable for powdery,granular,and small lump materials,such as flour,coal,cement,and grains. This series of equipment has significant advantages.The fully enclosed casing can effectively suppress dust flying and material spilling,ensuring a clean working environment.The precise matching of the screw blade and the casing realizes efficient conveying and reduces material residue.The conveying volume can be flexibly controlled by adjusting the driving speed. Its compact structure and small floor space can meet the installation requirements of narrow sites.Moreover,the high degree of standardization of parts and components makes maintenance convenient.Whether it is single-point feeding and multi-point discharging or multi-point feeding and single-point discharging,the LS series screw conveyor can meet the requirements.It is an economical and reliable device for the centralized conveying,transfer,and distribution of bulk materials.

WLS shaftless screw conveyor

The shaftless screw conveyor is a special bulk material conveying device that eliminates the traditional central shaft.Its core components include the shaftless screw blade,wear-resistant liner,drive unit,and fully enclosed casing.It is widely used in environmental protection,municipal,and food industries,and is suitable for materials that are prone to entanglement and blockage,such as sludge,food waste,fruit and vegetable residues,and sticky powders. The shaftless design fundamentally solves the common problems of material jamming in the gap between the shaft and blade,and fiber entanglement in traditional shafted conveyors.The screw blade is directly driven by the drive unit to rotate,and the material is pushed forward along the inner wall of the liner,significantly improving the smoothness of conveying. The fully enclosed casing prevents the leakage of odors and dust.The liner is made of wear-resistant materials to extend the service life of the equipment.The compact structure and flexible turning capability of the device make it adaptable to narrow spaces and multi-angle layout requirements.Although the conveying distance is relatively short,its strong resistance to blockage and ease of cleaning make it an ideal alternative to traditional shafted conveyors when handling materials with complex characteristics.

LLS double shaft screw conveyor

The double shaft screw conveyor is a highly efficient conveying device designed specifically for sticky, lumpy, or fibrous bulk materials. Its core feature is the two parallel, counter-rotating screw shafts, which are widely used in industries such as chemical, environmental protection, and food processing. It is suitable for special materials like sludge, distiller's grains, compound fertilizers, and biomass.The structure of the double shaft screw conveyor consists of a drive unit, double screw shafts (equipped with intermeshing blades), a fully enclosed casing, and inlets and outlets. When the double shafts rotate in opposite directions, the blades intermesh and shear, not only pushing the material along the axial direction but also breaking up lumps and mixing the components. This design solves the common problem of blockages in single-shaft conveyors.Compared to single-shaft models, the double shaft screw conveyor offers stronger resistance to blockages, more uniform conveying, and integrated mixing capabilities. The fully enclosed design prevents the leakage of odors and dust, making it suitable for horizontal or slightly inclined conveying applications. The robust shaft system and wear-resistant blade design ensure stable operation under harsh working conditions, making it an ideal choice for handling materials with complex characteristics.

Over-flow screw conveyor

The overflow screw conveyor is a specially designed screw conveyor. Its key feature is that the middle or a specific section of the conveyor is designed with an open or semi - open casing. When the amount of conveyed material exceeds the normal conveying capacity, the excess material can overflow from the open section. This allows for the quantitative distribution and diversion of the material. It is widely used in the building materials, agriculture, and mineral dressing industries. It is suitable for bulk materials such as cement, sand and stone, grains, and mineral powder.The structure is optimized based on the conventional screw conveyor. It retains the drive unit, screw shaft, and blades. The casing of the key section is modified to be open - top or fitted with an overflow trough. Some models are equipped with flow - regulating baffles to control the overflow amount.During operation, material enters from the inlet. The screw blades push it forward. When the material pile height exceeds the open height of the casing, the excess material automatically overflows into the designated collection device. This equipment combines conveying and diversion functions. It has a simple structure and is easy to adjust. It can precisely control the feed amount to downstream equipment. It is especially suitable for production scenarios that require material distribution or continuous unloading.
