EXTRACTING DUST: The fan sucks the air into an oil drum shaped
container and then through an internal filter. These machines usually
also make use of the cyclone effect to reduce the load on the filter.
This type of machine is cheaper, takes less space, has superior
filtration and has a stronger suction for hovering. The motor however
is very noisy and the airflow is much less than the external bag
machine.
The small filter clog quickly reducing he air flow
dramatically. The wood turner really need is a machine which moves a
larger volume of air at a lower speed breeze which wafts the fine
suspended dust away from the lathe into an efficient filter.
Those
extractors setups for paint spraying welding which consist of a large
three sided box built around the work area. Built into the rear of the
box in an array of huge powerful fans which sucks all fine dust and
fumes through suitably design filters at the rear and recalculate the
air. They work well because they move a very large volume of air.
Another
dust extractor BB100, this is a low cost fine dust extractor
(performance rating 3) for the hobby workshop. It is equipped with a
1000 watt vacuum cleaner motor which generates 195 cubic metres per hour
of air flow and provides enough suction to cater for even the smallest
of power tool inlets. The two stage filtration system consist of a
pleated paper filter, rather like a car filter, surrounding the in let
to the vacuum motor and a sub micron paper bag filter which totally
encloses the pleated filter.
Largest sized waste, such as planer
chippings, fall straight to the bottom of the drum whilst the smaller
dust particles are captured by the paper filters. The paper filters can
be easily replaced as necessary whilst the pleated filter can be a
vacuum cleaned periodically. Typical uses for this extractor are small
band saws, bench mounted sanding machines and portable power tools such
as routers, planners and sanders. It also serves as a very effective
vacuum cleaner for keeping the workshop clean and tidy.
1.1 AIMS AND OBJECTIVE
This project is aimed not only at providing a dust extraction machine in factories and workshops but:-
To provide a life equipment in the workshop which can be used for exhibition by students.
To
provide a machine (dust extractor0 which could be further modified and
improved on, for the extraction of dust from the atmosphere, which can
favourably compete with the best in the market.

ABSRACT - [ Total Page(s): 1 ]Man’s imp act on global environment system especially in the area of dust extraction is now at a scale where it is disrupting. These dust extractors varies in major ways. The environmental degration is, in turn contributing to health threat in this part of the globe. Unfortunately most factories, workshops which suppose to posses these machines for dust extractions a re not having them thereby making dust a very dangerous threat to man. Due to this ugly development it, is obvious th ... Continue reading---
