Scrap Metal

Introduction



SCRAP METAL:
Scrap metal is a term used to describe recyclable metals left over from every industrial production. It also includes any old metal,and any broken, worn out, defaced or partly manufactured articles made wholly or partly of metal and any metallic wastes.

Uses: The scrap industry processes more than 145 million tons of recyclable material each year into raw material feedstock for industrial manufacturing around the world. The industry contributed $65 billion in 2006 and is one of the few contributing positively to the U.S. balance of trade, exporting $15.7 billion in scrap commodities in 2006.

Scrap recycling also helps reduce greenhouse gas emissions and conserves energy and natural resources. For example, scrap recycling diverts 145 million tons of materials away from landfills. .

SCRAP IRON CARRIER:

It means a vehicle to carry scrap iron. In order to carry huge amount of scrap iron we are introducing a new type of scrap iron carrier.

Background

Scrap is often taken to a wrecking yard where it is processed for later melting into new products. A wrecking yard, depending on its location, may allow customers to browse their lot and purchase items . Customers are typically required to supply all of their own tools and labor to extract parts, and some scrapyards may first require waiving liability for personal injury before entering.

In the scrap metal industry a great potential exists for accidents in which a hazardous material present in scrap causes death, injury or environmental damage. A classic example is radioactivity in scrap; see the Goi nia accident for an example of an accident involving radioactive material which entered the scrap metal industry and some details of the behavior of contaminating chemical elements in metal smelters. So to avoid injuries and environmental damage we need srap metal carrier.

Objective

To make the sorting easy in a wrecking yard.

To ensure the safety of the customers in a wrecking yard.

To avoid the environmental damage such as radioactivity.

To carry the scrap metals in an organized way.

To separate the metals and non-metals.

To increase the rate of sorting metals.

Design

The design can be divided into three steps:

Mechanical part

Electrical part

Controller part

MECHANICAL PART:

Components:

1. Shaft
Material : Alumnium
Dimension : length -1.5 ft
dia. - 2 inch

Coupled to stepper motor and rotates 180
degree clockwise and anticlockwise along with the
truss.Aluminium shaft has been used due to its low
weight and high ductility.
