Introduction of Screw Conveyor
Screw conveyors, also known as auger conveyor,Spiral Conveyor, are made for simple conveying duties applications. The real strength of our company, however, is our ability to produce individually designed units that include features to overcome awkward installations, materials that are difficult to handle, or include performance or process functions beyond simple conveying. Some requirements may be concerned with aspects of hygiene, others with bulk solids that have poor or delicate conveying properties.
Screw conveyor is divided in two types rigid screw conveyor and shaftless screw conveyor.
Rigid screw conveyor is suitable for non-sticky powder and small particle material such as cement, fly ash, lime, flour, starch, food additive etc.
Shaftless screw conveyor is suitable for sticky and easy winding materials such as sludge, biomass.
Features of screw conveyor
*Tube type and U shape type available
*It can be designed inclined conveying,horizontal conveying and vertical conveying.
*Widely used for all kinds of powder,particles,small block and loose material.
*not suitable for conveying perishable material,high viscosity,less pressure resistant material.
*not suitable for agglomerate or high temperature material.
*not suitable for great corrosive special material and fragile material.
Warranty
Our machines have an automatic 12 months guarantee against faulty material and workmanship valid from the date of dispatch in China or date of arrival at foreign border.
If any problem of the machine under instruction within one year,we are responsible for replacement incuding delivery fee and maintenance.
Lifelong service is offered with cost charge after one year.

Recently, under the guidance of foreign experts, the world's advanced three-dimensional wave-making system was successfully installed and commissioned in CSIC 702, which enabled the wave laboratory simulation of the institute to reach the international first-class level.
As the basic research base of national ship mechanics, 702 has taken advantage of the advantages of technology and experimental facilities, and has made outstanding achievements in many scientific research fields such as overall ship performance, propulsion technology, ship structure, high-performance ship R&D and design, and underwater engineering. Achievements. With the continuous deepening of research on the performance of warships, the existing wave-resistant pools in 702 are far from meeting the needs of existing scientific research projects.
The modified wave-making system was introduced from the Netherlands and uses the most advanced servo motor driven serpentine multi-unit 3D wave machine. The system is controlled by a high-speed large-capacity computer with 16 motor control cabinets. Each motor control cabinet controls up to 12 AC servo motors, thus driving 188 wave-making boards to simulate various waves as required. Since each rocker plate has an independent servo motor drive device, the 188 rocker plates can simultaneously swing, create regular waves and long peak irregular waves, and can independently move, simulate three-dimensional short-peak waves, and can also be changed arbitrarily. The direction of the wave. The maximum wave of the regular wave is as high as 0.5 m, the irregular wave has a wave height of more than 0.4 m, the maximum wave height is 0.8 m, and the mechanical motion accuracy reaches one thousandth.
Compared with the previous hydraulic wave-making system, the wave-making ability of the wave-making system, the type of wave simulation and the quality of wave simulation are all international first-class, and it has low failure rate, low noise, no cooling water, and power-saving section. Water, no pollution and other advantages. The success of the installation and commissioning of the wave-making system marks that the construction level of the 712 research and experimental facilities will be upgraded to a new stage, which will provide a more powerful guarantee for the ship's shipworthiness, maneuverability and marine engineering.
