A study has been conducted at the Tehran cement factory to recognize and analyze the major noise emission source machineries Cement industry has many process units Basically all of these units or stages can be considered as a source of noise Since noise pollution is defined based on its of

Roots blower room in a cement plant is a major noise pollution source The room area is 57 m 2 with 2 single doors and 6 glass windows in which there are 3 Lobe Roots Blowers with airflow of 278 m3min through each blower and rotation rate of 1450 r min boosting pressure of 686 kPa power of 75 kW

Cement Plant Noise Control Cement plant noise up to 110 dB A comes mainly from crushers mills kiln burners compressors wagon tippler Our noise control measures include sound dampening machines components enclosing and noise source insulation

The noise generated by the fan is an important noise source in the cement plant which can sometimes reach 105 dBAHas produced serious noise pollution to the surrounding sound environment does not conform to the national noise standards if not promptly to control then can only be ore cement factory in the daily

St Marys Cement Group is one of the oldest cement companies in North America cement powder is produced by grinding the clinker in a ball mill contribution of each noise source to the overall sound levels of the site in

a cement kiln replacing a portion of conventional fossil fuels like coal if they meet strict specifications Selected waste and byproducts containing useful minerals such as calcium silica alumina and iron can be used as raw materials in the kiln replacing raw materials

pollution in cement plant is characterized by fixed point of noise source wide varieties of noise resource wide distribution of noise source and high level of noise pressure Table 1 Noise level in main workplaces Workplace Test numbers The highest noise leveldBA Crusher room 3 106 Ball mill room 3 101 Packaging machine room 3 85

Noise emissions occur throughout the w hole cement manufacturing process from preparing and waste is burnt in cement kiln Other sources of dust emissions include the clinker cooler

such as clay iron ore and sand as sources of alumina iron and silica respectively So common are these building blocks that a wide variety of raw materials are suitable sources and some sources such clay and fly ash may provide multiple chemical components Cement plants are

in cement kiln Other sources of dust emissions include the clinker cooler crushers grinders and materialshandling equipment Figure 1 Global Cement Production 19702050 Source International Energy Agency IEA These emissions are not only deteriorating air quality but also degrading human health Emissions have local and global

CEMBUREAU the European Cement Association based in Brussels is the representative organisation for the cement industry in Europe Its Full Members are the national cement industry associations and cement companies of the European Union and the European Economic Area countries plus Poland Switzerland and Turkey

May 09 2012 Though cement and concrete are often used interchangeably concrete is actually the final product made from cement The primary component of cement is limestone To produce cement limestone and other claylike materials are heated in a kiln at 1400C and then ground to form a lumpy
