Auger Screw Conveyor

Introduction of Auger Screw Conveyor

Auger screw conveyors help to move or convey items such as packaging, equipment, food or products from one area to another, often to perform automated or semi-automated finishing or manufacturing processes.

When the rotating screw or auger is properly installed inside the tube or cylinder, it can transport the material in the specified direction. In addition, each rotation of the screw allows new material to enter the tube.

Different Types of Auger Screw Conveyor

• 

  Stainless Steel Auger Screw Conveyor

  Safe, non-toxic, non-rusting, used in food, pharmaceutical or chemical industries.

• 

  Shaftless Auger Screw Conveyor

  Superior anti-winding properties, not easy to block, viscous, easy-to-wind material applications, such as mud, garbage, etc.

• 

  Tiwn Screw Conveyor

  1.5~2 times the conveying capacity, with the functions of mixing, breaking up and stirring at the same time.

• 

  Vertical Auger Screw Conveyor

  The most space-saving option for material lifting, occupying the smallest conveying area.

• 

  Portable Auger Screw Conveyor

  Flexible retractable and mobile design, suitable for scenarios where the workplace changes frequently.

Features and Benefits

1. The high-efficiency conveyor allows a large amount of materials to be transported in a small space, with a conveying capacity of 168m³/h.

2. With the help of the internal friction force of the material, the material is changed to be pulled, so that it can save 50% of electricity compared with the belt conveyor. It is suggested that the actual conveying capacity of the screw conveyor should not be lower than the minimum value of the conveying capacity. It is better to multiply the actual conveying capacity by 1.2, and it should not be higher than the maximum value of the conveying capacity.

3. The fully sealed casing makes the dust seamless and drillable, safe in operation and reliable in operation.

4. The process layout is flexible, it can be arranged on elevated, ground or pit, can be installed horizontally or on a slope (≤15°), or can be installed horizontally and on a slope with the same machine, and can be loaded and discharged at multiple points.

5. According to the actual conveying situation and conveying distance, special configurations such as single motor, double motor, explosion-proof and waterproof can be carried out to ensure safe operation.

According to different conveying materials and conveying conditions, we can choose different types of auger screw conveyors

Conveying high temperature resistant materials: need to choose high temperature resistant stainless steel auger screw conveyors

Conveying materials that need to be cooled: need to choose water-cooled auger screw conveyors

Conveying corrosive materials: auger screw conveyors with special materials such as stainless steel or plastic are required

Conveying viscous materials: Shaftless screw conveyors are generally selected according to the viscosity

Conveying powdery materials: need to choose a shaft screw conveyor

Horizontal conveying of materials: U-type LS type is required, or a tubular screw conveyor is selected according to the situation

Inclined conveying materials: need to choose tubular screw conveyor

Structure

Drive device: It is the power part, divided into single drive and double drive. The drive motor is suitable for 380V, three-phase, 50Hz, protection class IP55 (outdoor type), and insulation class F. The gear reducer has the advantages of high torque, low noise and no oil leakage.

Bearings: including fore and aft bearings and intermediate bearings. The head and tail bearings are arranged outside the machine slot, which is convenient for installation and maintenance, and at the same time prevents dust or materials from entering, and has a longer service life.

When the screw conveyor is too long, it is usually assembled in multiple sections. When it exceeds 3-4 meters, install the intermediate bearing, also known as the hanging bearing. Its main function is to bear part of the weight and the force generated by the operation of the screw shaft.

Machine slot: used to support the screw shaft and intermediate bearing, and provide a channel for conveying materials.

Spiral blade: choose carbon steel, stainless steel, manganese steel according to the material. For viscous and winding materials on conveyors, shaftless helical blades can be used.

Application

Auger Screw Conveyor can be used in almost all kinds of industries. The compact structure can adapt to the layout of most factories. It can be selected and designed according to the production situation. It can transport materials horizontally, vertically or at an oblique angle.

Auger Screw Conveyor can be used in food, medical, chemical, building materials, environmental protection, mining, agriculture and other industries. It can transport flour, pharmaceutical raw materials, additives, seasonings, spices, cocoa, ore, lime, feed, corn, soybeans, sludge, domestic waste, wood chips, chemicals and other materials.

Solutions by Industry

Auger Screw Conveyor used in the field of industrial building materials

The Auger Screw Conveyor in the industrial field generally has no special design. It is usually made of carbon steel. It can also be treated with stainless steel, white steel or other special treatments. Its main features are wear resistance and durability, large conveying capacity, and long conveying distance. Transportation requires Auger Screw Conveyor to be resistant to high temperature and corrosion.

It can be used to process industrial particles or powders such as fly ash, small granular stones, forging agents, etc., and can be used in conjunction with micro-screws, incinerators, elevators, and pulverizers.

Auger Screw Conveyor in the food industry

In order to ensure the safety of food production, the Auger Screw Conveyor in food processing plants is usually made of 304 food stainless steel, which ensures safety and is not easy to rust. It can be used for granules and powders from silos to screening machines, elevators or packaging machines. Food delivery.

The whole Auger Screw Conveyor is polished to be smooth and free of burrs. The gate is designed at the end, and the screw shaft can be reversed and cleaned to ensure that there is no food residue that will cause food to remain in the dead corner for a long time and cause deterioration and pollution.

Auger Screw Conveyor used in the field of environmental protection

When the Auger Screw Conveyor is used in the field of environmental protection, it is usually designed with corrosion resistance or a special design without a central shaft. The purpose is to prevent the corrosive materials in the environmental protection process from causing damage to the Auger Screw Conveyor too quickly and affecting the service life of the machine. At the same time, according to the situation of the material, it can also be designed for water cooling.
