Dust generation is one of the major problems in all kind of industries. Through different processes, the dust is generated and is mixed with the surrounding air. In addition to this, in manufacturing industries, a metallic dust is also generated by the operations like grinding, buffing, drilling, milling etc. Both types of dusts have bad effects on the human body.
The dust in the air is easily inhaled by the people working in the industry. This dust affects on respiratory tract and respiratory system badly. This dust leads to various respiratory problems. On the other hand, the dust generated through machining operations contains small metallic particles and metal chips. Along with getting this dust inhaled, it affects the skin by small cuts, infections, irritations etc. The metallic dust which is inhaled caused damage to lungs, respiratory system and even to the intestine. This metal dust may lead to serious diseases. Apart from all this health hazards, the dust available in the work atmosphere increases the temperature of the workplace making the person restless who is working on the workstation.
To avoid these ...
... hazards and to create safe and clean working atmosphere dust collectors are widely used in the industries. Both air dust collectors and metal dust collectors are used in manufacturing industries today. Typically, air dust collectors consist of a fan that either pushes or pulls the dirty air through some type of filtration. Dust in the air is collected on the filter and clean air is blown out of the unit. The filtration generally uses a mechanical process where filter is made up of porous material like cloth, paper or fiberglass. This filter is commonly called as net. When air passes through this net, the dust particles get caught in the net. In machining process, the dust follows along with the coolant or the cutting oil. This coolant and cutting oil is made to flow over a porous filter, usually cloth. The coolant or the cutting oil gets collected in the tank below the filter where the metallic dust gets accumulated on the filter. There are various models and mechanisms available in both the types of filters as per their specific intended use.
‘Powertech Pollution Controls’, one of the leading pollution control companies have come with a dust collector with brand name, ‘Dust Bag’. It is made up of non-woven polyester fabric as its medium of dust filtration, which is having antistatic properties. This dust bag makes use of conventional mechanical filter media. This dust collector has suction capacity ranging from 425 CMH to 9000 CMH. These specific dust collectors are used for collecting dust from:
• Tool and cutter grinder
• Cast iron machining
• Buffing
• De-burring & similar operations
• Chip extraction
Dust bags can also be fitted with self-balanced extractor arms of various lengths for added flexibility to capture dust from different dust generating sources.
