Shaftless screw conveyor, as a key equipment for handling complex materials such as sludge, kitchen waste, and chemical waste, its performance directly affects production efficiency. As a Shaftless screw conveyor suppliers who has been deeply involved in the field of industrial material transportation for many years, we have always been committed to providing high-quality shaftless screw conveyors and customized conveying solutions to global customers.
As a supplier of shaftless screw conveyors, materials and functions can be customized on demand, energy consumption is 18% lower, maintenance is less, and professional capabilities are used to provide you with high-quality solutions.
Innovative design: Abandoning the traditional shaft structure, an integral shaftless spiral blade design is adopted to fundamentally solve the problem of entanglement of fibrous materials. The equipment is equipped with two standard U-shaped/tubular trough structures. The U-shaped open type is easy to inspect and maintain, and the tubular closed type can achieve zero dust leakage to meet the environmental protection needs of different working conditions.
Strict quality control: The spiral blades are made of Q345B wear-resistant steel or 316L stainless steel, the key components are tested by ultrasonic flaw detection, and the trough welding accuracy is controlled within ±0.5mm.
Customized service
Flexible material selection: Provide multiple material solutions for different material characteristics: carbon steel + wear-resistant coating is suitable for abrasive materials such as sandstone, construction waste, etc.; food-grade 304 stainless steel is mirror-polished and suitable for flour and pharmaceutical powder transportation; 316L stainless steel trough for the chemical industry, with polytetrafluoroethylene lining, acid and alkali corrosion resistance is improved by 90%.
Functional modular expansion: Functional modules such as variable frequency speed regulation system, CIP online cleaning device, ATEX certified explosion-proof motor, etc. can be integrated as needed.
We provide full-cycle service for shaftless screw conveyors, from demand analysis, solution design to equipment customization, to escort the high-speed operation of the equipment throughout the whole process.

When purchasing a shaftless screw conveyor, you need to pay attention to the conveying distance, screw material, drive device and lining material, and match the efficiency and cost as needed.
Conveying distance: The conveying distance of a single machine is inversely proportional to the capacity. The maximum conveying length of a conventional single machine is 30 meters. If it exceeds this distance, a multi-stage series design is required. For example, when treating 200 tons of screen residue per day in an urban sewage treatment plant, 3 20-meter equipment must be configured in series to ensure conveying efficiency and stability.
Carbon steel: has significant cost advantages, suitable for conveying non-corrosive materials such as cement, sand and gravel, economical and practical.
304 stainless steel: has good general corrosion resistance and is widely used in food processing, chemical industry and other scenes with requirements for hygiene and corrosion prevention.
316L stainless steel: has outstanding resistance to chloride ion corrosion, especially suitable for strong corrosive environments such as seawater desalination and hydrometallurgy, ensuring long-term stable operation of equipment.
Cycloidal pinwheel reducer: compact structure and small size, suitable for light load and low speed conditions, such as daily powder conveying and other scenes.
Hard tooth surface gear reducer: strong load capacity and high transmission efficiency, specially designed for heavy load and high-speed conveying, can meet the high-intensity operation requirements of mine tailings, construction slag and other high-intensity operations.
Rubber lining: low cost but general wear resistance, suitable for conveying dry materials such as grains and coal ash.
Polyethylene lining: excellent self-lubrication, friction coefficient as low as 0.1, can effectively reduce the adhesion of sticky materials and improve the smoothness of conveying.
Cast stone lining: excellent wear resistance, Mohs hardness of 7, is an ideal choice for high wear scenarios (such as ore, sand and gravel conveying), can greatly extend the service life of the equipment.
