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.
