The document describes the design of a screw extruder machine for making sawdust briquettes. It discusses how sawdust from sawmills can be converted into briquettes, which provide an alternative fuel to fossil fuels and reduce environmental pollution from open burning of sawmill waste. The designed machine has a production capacity of 20kg/hr and can densify sawdust into briquettes with a density of around 800kg/m3. The document reviews various research papers on biomass briquetting and extruder machine design and discusses the motivation, design, and results of the sawdust briquette machine.

1. • The biomass briquette is made through the
densification of the ago-crop residues and biomass
waste.
• They are used as a flammable material in brick
kilns, paper mills, chemical plants, pharmaceutical
units, dyeing houses, food processing units, oil
mills, etc.
• The biomass briquette plant is one of the
renewable sources of energy, through which we
can reduce pollution.
• Biomass Briquettes are made from Agricultural
waste, Forest Waste, and Industrial Waste.
• In this project, we are designing a biomass
extruder for sawdust application.
INTRODUCTION

2. A briquette is a compressed block of coal dust or other combustible biomass material such as charcoal,
sawdust, wood chips, peat, or paper used for fuel and kindling to start a fire.
Densification Process
Piston press densification
• Roll press densification
• Pelletizing
• Low pressure or manual
• Screw press densification

4. MOTIVATION
• When fossil fuels are burned, they release carbon dioxide and other gases into the
atmosphere. Also, we are running out fossil fuels. We need new energy sources to
replace fossil fuels.
• Biomass Briquetting is the best renewable source of energy for a healthy
environment and economy, Biomass briquettes, are mostly made of green waste and
other organic materials.
• Biomass briquettes can be used for power generation or for thermal application but
mostly they are used for thermal application in industries replacing conventional
fuel

5. DESIGN OF SCREW EXTRUDER FOR BRIQUETTING OF SAWDUST FOR INDUSTRIAL
FURNACES.
• In this project, the sawdust briquette machine is designed. Sawmill waste is a big problem,
especially in urban cities. These wastes are burnt openly which is causing environmental
pollution.
• The wastes can be converted to wealth thereby providing jobs for many unemployed citizens.
The principles of machine design were employed to design the essential parts such as the
hopper, belts, housing barrel, die, and shaft. The machine has a production capacity of 20
kg/hr.
• The density of briquets is near about 800 kg/m3.

Design Of Screw-extruder Based Briquetting Machine For
Agricultural Residues
A screw-extruder based briquetting machine was developed, manufactured and tested for the utilization of two
common different agricultural residues I.E. Rice straw and cotton stalks.
2 Design Of Briquetting Machine For Biomass Briquette Fuel
This research was to design A briquetting machine to produce biomass briquette fuel by A cold compression process,
and to investigate its performance in terms of production rate and specific energy consumption.
3 Sawdust Briquetting Press Machine
This paper explains the designing, fabrication, and automation of A biomass ‘sawdust briquetting machine’. Sawdust
when used in form of briquettes gives more energy, produces less ash and is easy handle and possess less harm to
environment as compared to sawdust.
4 Design Of Sawdust Briquette Machine
The briquette machine has been designed. This machine has the capacity to produce 95kg of briquette in one hour
which is having A diameter of 25 mm

Design And Manufacturing Of Screw Briquetting Machine
For Compaction Of Biomass
Design and develop the screw briquetting machine for compaction of biomass obtained from agricultural waste of
diameter 30-70 mm and to improve its calorific value by testing of various compositions of briquettes
6 Design And Fabrication Of Biomass Briquetting Machine
Development of A substitute fuel for conventional fuels, such as wood, coal, charcoal and liquefied petroleum gas is
important. Briquette production technology, A kind of unpolluted coal technology, will facilitate to prevent global
warming and serve to conserve forest resources. The main ingredients of biomass briquettes are agricultural wastes
(such as straw, sugarcane, maize stalk, coconut husks and leaves, groundnut shells and rice husk), sawdust and the waste
papers from the municipal waste, which mainly act as A binding agent.

A Study Of Combustion And Environments Of Biomass
Briquettes From Sawdust Mixed With Glycerin
The combustion characteristics of briquette fuel produced from sawdust mixed with glycerin. The study compared the
combustion temperatures and mass reduction over time during combustion. The environmental impact was also studied
by detecting acrolein gas.

Wet Granulation In A Twin-screw Extruder: Implications Of
Screw Design
Wet granulation in twin-screw extrusion machinery is an attractive technology for the continuous processing of
pharmaceuticals. The performance of this machinery is integrally tied to its screw design yet little fundamental
knowledge exists in this emerging field for granulation to intelligently create, troubleshoot, and scale-up such
processes.

An Overview Of Extrusion As A Pretreatment Method Of
Lignocellulosic Biomass
Lignocellulosic biomass is both low cost and abundant, and unlike energy crops, can escape associated ethical
dilemmas such as arable land use and food security issues. However, their usage as raw material in A biorefinery
implies an inherent upstream pretreatment step to access compounds of interest derived from lignocellulosic biomass.

Extruder Biomass Briquetting Machines
The design of efficient screw extruder biomass briquetting machines is important for the utilization of loose biomass
materials from wood and agricultural wastes for the production of solid fuel. In this study, the effects of geometrical
parameters (channel depth and helix angle) and operational parameters (friction coefficient, mass flow rate and speed)
on the performance and design of the briquetting machine were investigated using A pressure model based on the
plug flow theory.

8. Result and Discussion

10. The briquette machine has been designed. This machine has the capacity to produce 95kg of briquette in
one hour. It can be easily fabricated with materials sourced locally. This project will provide job
opportunities to unemployed graduates, and small-scale entrepreneurs can be empowered by the
government by making briquettes from sawmill wastes. This will reduce the unemployment rate in India
and dependence on petroleum products for heating and cooking and also utilize waste generated by the
sawmill industries thereby reducing open air burning and attendant environmental pollution.
