Dust collection is an "on-line process" - for collecting any process generated dust from the source point itself on continuous basis. Simplest of all examples is grinding dust. While grinding on any type of grinding machine (say a bench grinder) some metal (or any other material) is removed from the job in the shape of fine dust. This dust can be an environmental problem or a health problem for the operator. This dust should, therefore, be entrapped at the source itself, before it spreads or becomes air-borne.
There can be several objectives of collecting dust, some of the important reasons can be following:
Protection of the operator
Protection of the production equipment from the dust
Protection of the job from the effects of dust
Protection of quality of environment in a premises
Recovery of the expensive material
CHOICE OF DUST COLLECTOR
The choice of the dust collector has to be made on the basis of following factors:
a. The process or the activity from where the dust is being generated
b. The type of material being process, e.g. steel, graphite, plastic, rubber, etc.
c. Nature of the dust being generated - its particle size population, temperature, shape of the particles, and other properties; like whether it is hygroscopic, toxic, inflammable, free-flowing or sticky, etc.
d. Quantum of dust : The peak quantity of dust generated per minute
e. Location of the dust collector with respect to the production equipment
f. Whether a suction hood is already installed, and, if not, what are the parameters which are going to affect the design of the suction hood, like size of the source point, no. of source points, other working/moving components in the vicinity of the job, loading/unloading of the job, etc.
g. What kind of dust disposal system will meet the requirements of the system - whether a batch disposal or continuous disposal will be required.
HOW DOES A DUST COLLECTOR WORK
In simple words - A suction hood is placed near the source point. This suction hood is connected to the dust collector which sucks in air and the dust comes along with it. This dust is separated from the carrier air and the clean air is allowed to escape, either within the premises or outside. Following are the essential elements of a dust collector:
Suction Hood
To extract dust from the source point
Ducting
To transport the dusty air from the hood to the dust collector unit
Dust separation system's)
To separate the dust from the dusty air
Filter cleaning device
To maintain the filter clean
Dust accumulation or disposal system
To collect or dispose-off the extracted dust
Suction generation device
A blower to create the required level of suction and airflow
Optional : Exhaust filtration system
To ensure that there is no residual dust in the exhaust air
Optional : Noise Reducer
To adjust the noise to acceptable level
Each one of the above elements contributes towards the success of a dust collection system. Often dust collection technology is taken lightly by the production or maintenance engineers of a manufacturing plant and they try to fabricate a simplistic collector, which, unfortunately, never works. It is not uncommon for us to deal with such customers who have either tried their own hands or have taken the services of a back-yard fabricator for this purpose and have burnt their fingers. We have replaced 30 HP unsuccessful systems with 3 HP successful systems We would recommend a serious reconsideration to those who under-estimate this technology.
A poorly designed/manufactured dust collector might cost less to begin with, but it might cost a lot over a short/medium term and may achieve absolutely nothing. Please, therefore, get in touch with us with all the details and take a quote. SANTONI, with its vast experience of the industry and over a thousand successful installations, is ideally placed to offer highly performance oriented dust collection systems.
