Hopper Screw Conveyor

Introduction of Hopper Screw Conveyor

 

Hopper screw conveyor is a screw conveyor designed to transport materials stored in a hopper, a container used to store bulk materials, the hopper screw conveyor is located below the hopper, and the material enters the screw through the feed port at the bottom of the hopper conveyor. Once the material enters the screw conveyor, the rotating screw will move along the length of the conveyor, being compacted and compressed by the screw as the material travels along the screw conveyor. This helps prevent inflation of the material and ensures its efficient transport. At the end of the conveyor, the material is discharged through an outlet at the end of the screw. Outlets can be designed to meet the specific needs of specific applications, such as chutes or discharge ports.

Hopper screw conveyors are commonly used in the food industry to convey materials such as flour, sugar and other ingredients. They are also used in other industries including agriculture, mining and wastewater treatment. Hopper screw conveyors can be customized to meet the specific needs of specific applications, making them a flexible choice for material handling.

Features and Benefits

1. The feeding pipe diameter is small, the hopper volume is 100-300KG, the conveying capacity per hour can reach 100-3000KG, and the feeding height can reach 2-12 meters.

2. The material in contact with the material is made of stainless steel. All welding ports are polished to achieve smoothness without residual material, which is clean and hygienic, and can avoid cross-contamination of materials.

3. The screw feeder uses the rotation of the eccentric block fixed on the main shaft of the motor to make the material box vibrate, and the material is easy to form flow and convection, so that it can achieve no jamming, no arching, and smooth discharge, which is suitable for poor fluidity. good material.

4. The screw can be reversed for discharging, and the lower end of the material pipe is provided with a gate, which can be opened to take out the stored material at the bottom of the hopper pipe from the door.

5. There is a material clearing port at the bottom, which can effectively prevent debris from entering the machine and cause blockage. An anti-blocking valve is set on the discharge end cover. If the material is blocked, the anti-blocking door will be opened due to the material accumulation, and then Cut off the power through the switch.

6. Sensors can be installed to effectively protect the motor from burning out. It can stop when the material is full, only need to set the material time, no need for workers to take care of it, and has functions such as material level control, overload protection, and automatic feeding.

Customized Types of Hopper Screw Conveyors

Hopper screw conveyors can be customized to meet the specific requirements of various applications. Here are some types of hopper screw conveyors that can be customized:

1. Tapered Hopper Screw Conveyor: This type of hopper screw conveyor is typically used when the bulk material being transported has poor flow properties. The hopper is designed with a gradually reducing cross-section, which helps to prevent material from bridging or clogging.

2. U-Trough Hopper Screw Conveyor: This type of hopper screw conveyor has a U-shaped trough that is used to contain the material being transported. The U-trough design helps to prevent material from spilling out of the conveyor during transport.

3. Vertical Hopper Screw Conveyor: This type of hopper screw conveyor is used to transport materials vertically. The hopper is typically mounted on a vertical support structure and the screw conveyor moves the material up the structure.

4. Heavy-Duty Hopper Screw Conveyor: This type of hopper screw conveyor is designed to handle heavy-duty applications. The screw conveyor is typically made of heavy-duty materials such as hardened steel and the hopper is reinforced to withstand the weight of the material being transported.

5. Sanitary Hopper Screw Conveyor: This type of hopper screw conveyor is designed for applications where cleanliness and hygiene are critical. The conveyor is typically made of stainless steel and is designed to be easy to clean and sanitize.

Overall, hopper screw conveyors can be customized to meet the specific needs of various applications. Customizations can include changes to the hopper design, screw design, and support structure, as well as the addition of features such as covers, discharge spouts, and sensors.

Structure of the Hopper Screw Conveyor

Hopper screw conveyor is mainly composed of feeding port, spiral blade, cylinder, driving device, discharge port and so on. During operation, after the material is conveyed to the shell of the hopper screw conveyor through the feeding port, the material is subjected to the centrifugal force and the frictional force of the pipe wall in the internal spiral groove, rotates together with the spiral blade, and moves along the spiral groove under the action of gravity. Sliding down, so that the material is continuously pushed forward and conveyed, and finally evenly discharged from the discharge port.

Application

Hopper screw conveyor is mainly used for powder and granule feeding. It is suitable for feeding equipment with certain high requirements. It can be used with various specifications of extruders, high-speed mixers and plastic mixers.
