INDRODUCTION

Briquetting is increasing the density of loose particles,

pulverised materials such as rice husk, sawdust, wood-shavings,

coconut fibers, palm fruit fibers and other agricultural wasteetc.

into briquettes by means of a binder such as starch.

Briquette is a block of flammable material used as fuel toinitiate and sustain fire. Briquettes can be made from

biomass, or blends of biomass and coal-dust.

A briquetting machine acts as a recycler that converts

biomass wastes into a renewable energy, acting as a substitute

for fossil fuels.

PROBLEM STATEMENT The world’s population is steadily increasing with a

proportional increase in the demand for energy

considering the low production rate of crude oil.ExcessMunicipal Solid Waste leading to Environmental pollution

and causing a blockage to our sewage system.In view of

this, it is necessary to evaluate a cost effective form of

energy which is economical with little or no green house

effects which is a renewable form of energy and it’s

importance to create more awareness of renewable

source of energy from Municipal Solid waste so as to

convert waste to wealth.


5/18

MOTIVATION

Briquettes acts as an alternative fuel source.

Briquettes have low sulphur content, relative freedom

from dust, ease of handling and high calorific value.

Briquetting provides a solution for municipal and

agricultural wastes that causes a nuisance in our

environment.

It helps to get best fuels from waste.

Briquetting converts waste to wealth.


6/18

ADVANTAGES OF BRIQUETTING

Cheaper than coal and other fossil fuels.

Better burning efficiency.

Biomass briquettes have a higher practical thermal

value.

There is no sulphur in Briquettes, thus does not pollutethe environment.

Briquettes, are easy to store, pack and hygienic to

handle.

AIM AND OBJECTIVES

To design and fabricate an electrically operated briquetting

machine.

To produce briquettes that will reduce air pollution.

To improve on the existing briquetting technology to a level

that provides ease and comfort.

LITERATURE REVIEW

In 2012, Osarenmwinda and Ihenyen O.I both designed

and fabricated a briquetting machine that has a capacityof ten tonnes for small scale manufacturers.

The limitation of this design is that the hydraulic jack

which is manually operated will take a longer time in

producing briquettes.


10/18

LITERATURE REVIEW

Arinola B. Ajayi, Justina I. Osumune designed

and constructed a single extrusion die screw

press briquetting machine. It consists mainly of

driving motor, screw, die, belts and the housing

with a hopper.This machine has the capacity to produce 95kg of

briquette in one hour.

The limitation of this design is that the die head

is subjected to severe wear as the feeder screwcontinuously forces the material into the die.

METHODOLOGY

Execution

Method of fabrication is by welding.

Method of motion is a reciprocating motion.

Controlled electronically with a hydraulic

pump.

14/18

METHODOLOGY Principle of operation

Saw dust or waste will be mixed with binder (starch) and

placed into the compaction chamber.

The mould cover will be closed.

An hydraulic jack is used to lift the bottom plate with

the aid of an electric hydraulic pump.

The briquettes are ejected by opening the mould cover.

RELEVANCE OF COURSE TO STUDY

PHY 101 - BASIC PRINCIPLES OF PHYSICS.

MEE 101 - ENGINEERING DRAWING.

MEE 309 - STRENGTH OF MATERIALS.

CONCLUSION

The briquette obtained from the machine can used as

alternate to fuel-wood in domestic cooking and small-scale

industries.

The machine will enable agricultural waste to be removed

from the environment, thereby preventing environmental

pollution.

Reduce unemployment rate.
