CATHAY screw conveyor: screw drive, an efficient choice for material transportation

1. Screw transmission to achieve continuous and stable transportation

CATHAY screw conveyor uses spiral blades as the core transmission component, relying on the motor to drive the reducer to drive the spiral shaft to rotate. When the material enters the machine slot, it moves axially along the inner wall of the machine slot under the push of the rotating spiral blade, thereby realizing continuous transportation of the material. The spiral blade adopts a gradual pitch design, with a larger pitch at the feed end to facilitate the smooth entry of the material; the pitch at the discharge end gradually decreases to enhance the pushing force on the material, ensuring that the material is transported without retention or blockage. The conveying direction of the equipment can be flexibly set to horizontal conveying, inclined conveying (inclination angle ≤30°) or vertical conveying according to demand, meeting the layout requirements of different production scenarios, and the conveying capacity can reach 1-100 tons per hour, and the conveying distance can be up to 30 meters, realizing efficient and stable material transmission.

2. Multi-material adaptation, covering the transportation needs of multiple industries

Mining field: Whether it is ore particles and concentrate powder of metal mines, or kaolin, quartz sand and other non-metallic minerals, CATHAY screw conveyors can easily cope with it. In the mineral processing process, the crushed ore particles can be transported from the crushing equipment to the ball mill, and the concentrate powder after flotation can be transported to the concentration equipment or dryer. The material loss rate during the transportation process is less than 1%, ensuring full utilization of the materials.

Building materials industry: suitable for the transportation of bulk materials such as cement, lime, sand and gravel. In the concrete mixing station, cement, fly ash and other powders can be accurately transported to the mixing host. The transportation process is closed to avoid dust flying and keep the production environment clean; in brick and tile production, raw materials such as clay and shale can be transported to ensure continuous supply of raw materials and guarantee the production rhythm.

Chemical industry: For granular and powdered chemical raw materials (such as fertilizers, plastic particles, dyes, etc.), the equipment is made of corrosion-resistant materials, which can resist the erosion of chemical raw materials. It does not react chemically with the materials during transportation, ensuring the purity and stability of the materials, and meeting the stringent requirements of chemical production for material transportation.

Agricultural field: It can be used for the transportation of grain (wheat, corn, rice), feed, straw and other materials. In grain storage, the harvested grain can be transported from the transport vehicle to the granary, and the transportation process is smooth to avoid grain crushing; in feed processing, the mixed feed raw materials are transported to the pelletizer to ensure the continuity of feed production.

Environmental protection industry: For semi-fluid or viscous materials such as municipal sludge and industrial waste, CATHAY screw conveyors are equipped with special wear-resistant spiral blades and anti-sticking machine grooves, which can effectively prevent material adhesion, ensure smooth transportation, and help the material processing and transportation of the environmental protection industry.

3. Structural design to ensure equipment durability and environmental protection

High-strength body: The machine trough is welded with thick-walled steel plates, and the internal stress is eliminated through aging treatment, which has excellent deformation resistance; the spiral shaft is processed with 45# seamless steel pipe or solid round steel, which has high strength and good rigidity, can withstand large material thrust, and the overall service life of the equipment can reach 8-10 years.

Wear-resistant and anti-corrosion treatment: The surface of the spiral blade is treated with wear-resistant surfacing or sprayed ceramic coating, with a hardness of more than HRC50, and the wear resistance is increased by 3-5 times, which is especially suitable for conveying materials containing hard particles; for corrosive materials, the machine trough and spiral blades can be made of 304 or 316 stainless steel, which has excellent corrosion resistance and prolongs the service life of the equipment.

Enclosed design: The machine trough adopts a fully sealed structure, and the feed inlet and discharge port are equipped with sealing flanges, which are closely connected with upstream and downstream equipment, effectively preventing material leakage and dust overflow, and the dust emission concentration is less than 10mg/m³, which meets national environmental protection standards, improves the working environment, and ensures the health of operators.

Easy-maintenance structure: The equipment is equipped with multiple inspection ports and observation windows, which are convenient for operators to regularly check the operating status of the equipment and perform maintenance; the spiral shaft and the bearing seat are detachably connected, which is easy to operate when replacing the spiral blades or bearings, reducing downtime for maintenance and improving equipment utilization.

4. Performance advantages, improving conveying efficiency and stability

Smooth operation and low noise: The high-precision gear reducer is matched with the motor, the transmission is smooth, the operating noise is less than 75 decibels, creating a quiet production environment; the gap between the spiral blade and the inner wall of the machine slot is controlled at 5-10mm to avoid friction noise and material jamming during operation.

Flexible speed regulation and precise control: Equipped with a variable frequency speed regulation motor, the conveying speed can be flexibly adjusted according to the processing capacity of the downstream equipment, achieving accurate material transportation and supply and demand balance, avoiding material accumulation or insufficient supply, and improving production efficiency.

Low energy consumption and low operating cost: The transmission efficiency of the equipment is as high as over 90%, and the motor power is reasonably configured according to the conveying volume and conveying distance. The energy consumption is 10%-20% lower than that of traditional conveying equipment; the equipment has a simple structure, few wearing parts, low maintenance cost, and annual operating cost is 15%-25% lower than that of similar equipment.
