What is a Screw Conveyor and How Does It Work?<\/h2>\r\n

A screw conveyor is a device used for conveying bulk powder, granular, and even some semi-solid materials. This system consists of a metal screw that rotates inside a tube or U-shaped housing, moving materials forward with its rotation. The principle of this device dates back to the 3rd century BC and Archimedes' invention, but today it has become much more advanced with modern technology. At Kian Industry, we use European gearmotors, durable bearings, and precisely engineered screws to ensure the highest efficiency and minimal wear. In this system, the gearmotor rotates the screw, and materials enter through the inlet, gradually being pushed toward the outlet. A major advantage is the ability to convey at various angles, even vertically, as well as handling sticky materials with special screw and housing designs. This device is very suitable for factories with limited space because it occupies a small footprint and can be installed at various heights. Kian Industry's screw conveyors are manufactured in closed tubular models for complete dust prevention and U-shaped models for easy access to the screw. Both types are built to international standards and undergo full performance testing before delivery.<\/p>\r\n \r\n

The working process is as follows: materials enter the housing from the inlet hopper, the screw pushes them forward at a controlled speed, and they are discharged at the outlet to the next device or silo. The rotational speed is typically between 40 and 100 RPM and can be controlled with an inverter. This flexibility makes the screw conveyor ideal for production lines with varying capacities. Additionally, level and flow sensors can be installed for full automation.<\/p>\r\n <\/div>\r\n\r\n \r\n

History of Screw Conveyor Manufacturing and Its Origins<\/h2>\r\n

The history of the screw conveyor goes back to the Greek mathematician Archimedes, who used it to remove water from ships. In the 19th century, with the Industrial Revolution, this device was used for conveying grain and minerals. In the 1950s, with the advancement of chemical and food industries, closed and sanitary models were developed. Today, companies like Ceylan Makina produce intelligent models with load and speed control sensors. Kian Industry, by transferring this technology to Iran and localizing it, meets the needs of domestic industries. Before the invention of this device, factories faced many problems in handling powder materials, such as dust leakage, environmental pollution, damage to sensitive materials, and high energy consumption. The screw conveyor solved all these problems and therefore quickly spread across all industries.<\/p>\r\n \r\n

In Iran, with the growth of cement, petrochemical, and food industries in recent decades, the demand for this equipment has increased. Kian Industry, in cooperation with Ceylan Makina, has been able to produce models that are suitable for Iran's climate and materials, offering greater durability and lower maintenance costs.<\/p>\r\n <\/div>\r\n\r\n \r\n

Applications of Screw Conveyors in Various Industries and Competitive Advantages<\/h2>\r\n

In the cement industry for conveying cement powder, clinker, and lime; in the mining industry for powder materials and concentrates; in the food industry for flour, sugar, milk powder, grains, and spices; in pharmaceuticals for conveying sensitive and sterile powders; in petrochemicals for granules and polymer powders; in animal and poultry feed production; and in hundreds of other applications, this equipment is present. Kian Industry has executed numerous projects in cement factories in Tehran, Isfahan, and petrochemical plants in the south of the country. The advantages of using a screw conveyor include: significantly reduced energy consumption compared to pneumatic systems; dust-free and environmentally clean conveying; very easy and low-cost maintenance; long service life (over 15 years with proper maintenance); full customization capability based on customer needs; and a 24-month warranty with 10-year support.<\/p>\r\n \r\n

This device occupies less space than belt conveyors, transfers sensitive materials without damage compared to bucket elevators, and has much lower operating costs than pneumatic systems. In modern production lines, the screw conveyor plays a key role because it is accurate, reliable, and economical. Kian Industry is ready to design and supply this equipment for your production line. Considering the variety of materials and conditions of each factory, our engineers provide custom designs to achieve the best performance.<\/p>\r\n \r\n
