Flexible Screw Conveyor

Flexible screw conveyor, also known as a flexible auger conveyor or helix conveyor, is a type of mechanical conveying system used to transport bulk materials in a flexible and efficient manner. It consists of a flexible screw enclosed in a flexible or rigid tube, with one end of the screw connected to a motor or drive mechanism.

Flexible screw conveyors can handle a wide range of bulk materials, including powders, granules, flakes, pellets, and small particles. They can be used for conveying materials such as grains, chemicals, fertilizers, plastics, pharmaceuticals, food products, and more.

Types of Flexible Screw Conveyor

1、Hand Grain Suction Machine：



The machine is light in weight, small in model design, and small in thrust when working, which enables it to work hand-held and reduce work intensity.

2、Mobile Grain Suction Machine



The movable gripper design can clamp the side wall of the truck and realize the transportation of grain from low to high without other arrangements.

Application

Flexible screw conveyors have a wide range of applications across various industries. Some common applications of flexible screw conveyors include:

1.Agriculture and Farming: Flexible screw conveyors are employed in the agricultural sector for handling various types of granular or powdered materials. They assist in conveying fertilizers, seeds, grains, animal feed, and other agricultural products, both in storage facilities and during the loading or unloading of farm equipment.

2.Plastics and Polymers: The plastics industry often utilizes flexible screw conveyors to transport plastic powders, resins, pellets, and additives. They enable the efficient transfer of materials to extruders, injection molding machines, mixers, or packaging units.

3.Mining and Minerals: Flexible screw conveyors are utilized in mining and mineral processing for handling powdered or granular materials like ores, coal, limestone, and minerals. They can be used for transferring materials between different processing stages or for loading trucks or railcars.

4.Construction sites: Flexible screw conveyors are used to transport mortar, sand and other construction materials. They transport these materials from storage areas or mixing stations to the construction site where workers can carry out masonry, plastering or other construction work.

Features and Benefits

1. One machine is multi-purpose, which can suck and transport grain, and can suck and transport granular fertilizer, feed, chemical products and other non-corrosive granular materials.

2. The Flexible Screw Conveyor is small, lightweight and designed as a flexible hose, the pipe can be bent in any direction, and can easily handle bulk material conveying at various angles.

3. It can be used for loading, bagging, warehousing or unloading of a single grain suction machine, or it can be used with other conveying equipment and screening equipment.

4. The grain suction mouth is a special suction nozzle for particle suction, which can work deep into the grain pile with a depth of 6 meters.

special design

1. Flexible screw conveyor is divided into the thickness of the pipe diameter. The commonly used pipe diameters are 10 cm, 12 cm and 16 cm. Of course, there are also 11 cm and 14 cm or 18 cm pipe diameters. Of course, the thicker the pipe, the flow rate and output can be improved accordingly.

2. Flexible screw conveyor is divided from the driver. Driven by electric motors, driven by electric drills, driven by modified diesel vehicles, driven by gasoline engines, and driven by batteries in battery vehicles.

3. Flexible screw conveyor is divided into two parts according to the position where the motor is placed. Double-pipe grain suction machine and single-pipe grain suction machine. The motor of the double-pipe grain suction machine can push back and forth on the ground. Light and easy on both the feed and output sides. The single-pipe motor is on the grain output side. It looks a little bulky, and is suitable for fixed places where the location is not changed frequently.

Structure of Flexible Screw Conveyor

Flexible screw auger conveyor is composed of five parts: a flexible outer pipe, a auger spring, the head and tail

of the machine, and motor.

Flexible outer pipe: The spiral tube is made of high-quality beef tendon material, and the tendon tube has the characteristics of wear resistance and cold resistance.

Auger spring: Made of manganese steel, the spiral blade adopts shaftless structure, which is convenient for rotating of the auger spring.

The head and tail: The user-friendly design makes the machine convenient and fast.

Motor: The motor adopts 220V single-phase electric / 380V three-term electric, power 2.2 -4kw.

The motor shaft and the coil spring are connected by a screw. When the motor is started, the motor drives the coil spring to rotate, and the grain in the collecting port will rise along the direction of the helix angle of the spring under the action of the rotating spring, and when it reaches the discharge port , Due to the action of gravity, the grain is automatically unloaded.
