SOURCES OF ENERGY ppt

The waste materials and dead parts of living things are called biomass Eg :- wood animal dung Wind energy is used in wind mills which converts the kinetic energy of the wind into mechanical or electrical energy Some sources of energy are non renewable like coal petroleum and natural gas 3

Energy and temperature analysis in grinding

Energy and temperature analysis in grinding W B Rowel M N Morganl A Batakol T Jin2 I School of Engineering Liverpool John Moores University UK 2 S I MS CranJield University UK Abstract Energy consumption and dissipation are discussed leading into a thermal model for grinding

The Future of Steel

+ The energy needed to melt scrap represent 40% of the energy and 30% of CO 2 to smelt iron ore in a modern BF/BOF integrated mill + In addition capital cost per tonne of capacity is 60 to 70% lower maintenance costs are decreased in the same proportion + Labor productivity is twice as high and smaller size of mill usually leads

Wind Energy

The benefits of increased deployment of wind energy include grid-wide energy savings and reductions in greenhouse gas emissions and air contaminants (including SO X NO X and mercury) For example a single installation of six 65 kW wind turbines in Newfoundland is expected to produce approximately 1 million kWh of electricity a year and reduce CO 2 emissions by approximately 750 tonnes

Factors Affecting Ball Mill Grinding Efficiency

b) Feed Preparation – With more widespread use of coarse ball milling it is increasingly important to present a suitable feed material top-size to the ball mill Significant inefficiencies are introduced as a result of the need for larger (and as a result fewer) grinding balls Furthermore as mill performance is related to the complete size distribution of the feed material all

TECHNICAL NOTES 8 GRINDING R P King

2 Lifters prevent slipping between the medium and slurry charge in the mill and the mill shell Slippage will consume energy wastefully but more importantly it will reduce the ab ility of the mill shell to transmit energy to the tumbling charge This energy is required to cause grinding of the material in the mill

Hammer Mill: components operating principles types

Disadvantages of Hammer Mill Not recommended for the fine grinding of very hard and abrasive material due to excessive wear Not suitable for low-melting sticky or plastic-like material due to heat generation in the mill head as a result of mill fouling The mill may be choked if the feed rate is not controlled leading to damage

Comminution processes: Basics and application to energy

1 Specific energy of mill compared to new created surface energy → not meaningful efficiency much smaller that 1% 2 Specific energy of mill compared to minimum specific energy requirement in so-called element tests However here at least two possibilities exist: a breakage energy of single particle stressing by compression / by impact
