Construction Of A Screw Conveyor With A Single Phase Electric Motor
A screw conveyor, driven by a single-phase electric motor, efficiently transports bulk materials within industrial settings. This versatile apparatus, leveraging the rotational force generated by the motor, facilitates seamless material handling across various sectors such as agriculture, manufacturing, and construction. The design of the screw conveyor ensures reliable and continuous movement of granular or powdered substances, enhancing operational efficiency and minimizing manual labor. Employing a single-phase electric motor optimizes energy consumption while maintaining robust performance, making it a cost-effective solution for material conveying needs.
In the society at large Technology is fast replacing the crude method of carrying out work and has been making room for employment. Besides, it has also caught the attention of the youths who will prefer to work in a company with technological operations than one with man-power operations. This project can be used to convey materials ranging from those in powdery forms grit forms, and stones in the size of crushed granites. If applied to the foundry technology practical (sand mould) under gone by the department. The lecture will experience ease in carrying out his lecture as well as satisfaction since there would not be lack of sand as this can be seen to, by an attendant and the lectures will have all the student of the Department in attendance.

1.1 INTRODUCTION
CONVEYORS
This is any of various devices that provide mechanized movement of materials as in a factory; they are used principally in industrial applications but also on large forms in warehousing and freight handling, and in movement of law materials. They may be only a few meters in length or they may be in regretted systems several miles along.
Also, it could said to be a family of materials handling machine designed to move individual articles of solid.
Free flowing bulk materials over a fixed horizontal, inclined, declined or vertical path of travel with continuous motion.
SCREW CONVEYOR
This is a conveyor consisting of a helical screw that rotates upon a single shaft within a stationary tough or casing, and which can move bulk material along a horizontal, inclined or vertical plane. It is also known as AUGER CONVEYOR, SPIRAL CONVEYOR. AND WORM CONVEYOR.
The idea to build this project dawned on us during our practical on the course January technology. We (the students) in ought in sand for a mould practical which was screened by the lecturer and the appropriate ones selected for the practical to be carried out.
This project is necessary because it will did the lecturer in his lesson as well as stop the stress being put on students to go out and dig up sand for the practical.
The need for this project is to convey sand lactated in a strong facility through the conveyor to the point of use. These builds up on eagerness or learn in the students with the project being a point of interest.
1.2 DESCRIPTION
Screw conveyors consist of revolving shafts with a continuous or broken spiral fighting that operates insides a casing. This is powered by an electric motor and suitable gearing, the screw conveyor usually operates in one direction only to move fine bulk material such as meal, seed, coal, etc from one point to another point.
Construction Of A Screw Conveyor With A Single Phase Electric Motor:
Constructing a screw conveyor with a single-phase electric motor involves several steps, and you will need some mechanical and electrical skills, as well as access to the necessary tools and materials. Here’s a general overview of the process:
Materials and Tools You Will Need:
- Steel or stainless steel pipe or tubing for the screw conveyor casing.
- Steel or stainless steel helical screw blade.
- Bearings and housing for supporting the screw shaft.
- Single-phase electric motor.
- Motor mount and coupling.
- Metal cutting tools (e.g., hacksaw, bandsaw, or angle grinder).
- Welding equipment (if welding is necessary).
- Bolts, nuts, and other fasteners.
- Electrical wiring and components (cables, switches, connectors, etc.).
- Safety equipment (gloves, goggles, etc.).
Steps to Construct the Screw Conveyor:
- Design the Screw Conveyor: Before you start building, you need a detailed design that specifies the dimensions, capacity, and materials to be used. This will be based on your specific application and requirements.
- Cut and Prepare the Materials:
- Cut the steel or stainless steel pipe or tubing to the desired length for the screw conveyor casing.
- Cut the steel or stainless steel helical screw blade to the required length and shape.
- Fabricate any other components needed for your specific design.
- Assemble the Screw Conveyor:
- Weld or bolt the screw blade to the screw shaft, ensuring it is securely attached.
- Attach bearings and housing to support the screw shaft at both ends. Proper alignment is crucial to prevent wobbling.
- Mount the screw conveyor casing around the screw shaft and secure it in place. Ensure that it is concentric with the shaft.
- Install the Electric Motor:
- Attach the single-phase electric motor to a motor mount and coupling. The coupling will connect the motor shaft to the screw conveyor shaft.
- Make sure the motor is properly aligned with the screw conveyor shaft to avoid misalignment issues.
- Wire the Electric Motor:
- Connect the electrical wiring to the motor, following the manufacturer’s instructions and local electrical codes.
- Install any necessary switches, controls, and safety features, such as emergency stop buttons.
- Test and Adjust:
- Before operation, thoroughly test the screw conveyor to ensure that it runs smoothly and efficiently.
- Check for any unusual noises, vibrations, or issues with alignment.
- Adjust the motor speed and conveyor speed as needed for your application.
- Safety Considerations:
- Ensure all safety precautions are taken during construction and operation.
- Guard moving parts to prevent accidents.
- Follow safety guidelines for welding and electrical work.
- Maintenance and Lubrication:
- Establish a maintenance schedule for lubricating bearings and inspecting the conveyor regularly to prevent wear and tear.
- Operate the Screw Conveyor: Once everything is properly assembled, wired, and tested, you can start using the screw conveyor for your intended purpose.
Remember that building a screw conveyor is a complex task that requires careful planning and consideration of safety standards. If you are not experienced in mechanical and electrical work, it is advisable to seek assistance from professionals or experts in the field. Additionally, ensure that you comply with all relevant local regulations and safety standards during the construction and operation of your screw conveyor.
