Powder Spray Booth with recovery:-
Description:-
The Spay Booth is the part of the system in which jobs are hanged over for
powder spray. Main function of the spray booth is to provide clean atmosphere
and to bar atmospheric influences on the job like wind, dust etc. It provides

3. healthy and clean surrounding in powder coating area. Recovery system
provides recovery of overspread powder with the help of cyclone formation in
collection chamber so that the powder is collected in recovery bin and only
clean air goes out to the air. Cyclone recovery system works so efficiently that
it recovers almost 97% to 98% of the over sprayed powder.
Construction: -
Spray booth casing is made up to 16/18 swg steel with supporting structure
having illumination, rotating device, control of air blower and a plug point for
spray equipment. Recovery system is made out of 18 swg steel with removable
body for cleaning. It is supplied with exhaust blower with motor, supporting
structure and quick release bin. Connecting duct from spray booth to recovery
cyclone is fixed at 1 end of spray booth with flanges, it is designed in such a
way that powder does not stay in the duct. Bin is is also removable type for
easy collecting and cleaning.
After assembly, exhaust blower sucks the air from front opening of spray
booth where the over sprayed is mixed with the air, passes through the cyclone
duct. The blower provides cyclonic action due to which heavier particles of the
powder settle down in the bin and clean air moves out. Air velocity at the
opening of the booth is maintained to facilitate optimum collection of powder.
Whole system is designed for maximum safety of the operator.

Construction: -

4. The oven is made out of 16/18 swg steel in cassettes form. Oven structure is
made out of 3 mm thick sheet steel formed in angle shape or 40x40x5 mm
angles. The cassettes are made in double walled type construction filled with75
mm insulation of mineral wool or glass wool. These cassettes are provided with
partitions so as to avoid any sagging of wool inside. Cassettes are then joined
with angled frame to make a box type construction. Gap between them is
further filled with insulation to avoid any leakages.
Heaters used in ovens are made up of stainless steel suitable to high
temperature for better efficiency and durability. These are divided in 3 circuits.
One thirds are operated manually while two thirds are controlled by automatic
digital temperature control. All heaters are provided with separate MCB's to
provide working safety and ease of maintenance of each one individually.
Statically and dynamically balanced blower is mounted on the top which
recirculates the air in the oven thereby maintaining the temperature and avoids
the formation of air pockets.

Powder/Paint curing oven ( LDO fired /LPG / CNG ):
-
The ovens are basically either a box or tunnel type in construction. The 18 swg
sheets of CRC are used in the construction of the oven. Frame of the oven is
made out of 3 mm thick sheet steel which is formed in the shape of angles. The
cassettes are made of steel in double walled construction with bent edges. To
make it heat proof 100 mm glass/mineral wool insulation is provided and
provisions are made so that the wool does not sag. The gap is then sealed with

5. silicon adhesive sealants so that there is no escape of heat. To provide energy to
the oven we use HSD/LDO burner. The burner is mounted on a heat exchanger
with asbestos mounting to make it leak proof. A heat exchanger constituting
firing chamber and tubes is provided for better transmission of heat throughout
the oven and it's longer life. Fuel gases exhaust point is also provided in heat
exchanger so that waste gases are exhausted through the chimney. Heat
exchanger is mounted on rails so that it can be easily cleaned and maintained.

Conveyorized Systems: -
Before considering the design and implementation of a conveyorized powder
coating system, a few questions need to be answered. Proper design begins with
preparation and research.
Where will the system be built?

6. Location is essential for efficient transportation of products to and from the
powder facility.
What is the available floor space?
As you begin designing the powder application system, it's important to have a
clear understanding of the facilities floor space and the location of each of your
utility hook-ups. It can be very costly to find that you placed your pretreatment
area on the wrong side of the building, away from drainage and water hook-
ups.
What size is the largest part that will move through the application system.?
Length, width, height and weight are considerations.
What kind of production rates are necessary?
Consider short and long term requirements.
What utility capacities are available?
Electrical, water, gas and air; and drainage lines.
What permits are required?
Building permits for modifications, air quality requirements, fire protection,
sanitation.
These requirements may be different in each location. And, this listing is not
meant to be complete. You need to do your homework. Proper research saves
time and money.
The conveyorized system is for higher production needs and generally begins
with a loading station for the loading of jobs onto a properly grounded
conveyor and racking system. A conveyor to transport jobs from one station to
the next is essential. The importance of cleaning and proper lubrication of the
conveyor cannot be over emphasized.
The conveyor transports the parts into the pretreatment system which generally
consists of a three or five stage spray washer, most often iron or zinc
phosphate. The washer includes rinse stations that use fresh, recycled and/or
deionized or filtered water.
With the phosphate spray washer, your chief concerns are:

7. The control of time, allowing the various stages to perform their desired
functions.
The control of temperature, enhancing cleaning and phosphating.
The control of chemical concentration, the amount of chemical in solution is
measured by titration, allowing the cleaning and phosphating baths to be
monitored and adjusted.
The control on nozzle pressure, relating to impingement properties and the
physical removal of soils and surface contaminates.
Proper line speed and constant monitoring of all control variables will ensure a
clean, uniform surface. Also accurate maintenance and record logs are
necessary to keep your operation running smoothly and efficiently.
As the parts leave the pretreatment area they are wet from rinsing and must be
dried. Forced drying takes place in a separate dry-off oven, or a section of the
cure oven. Using the cure oven reduces the system's size and eliminates the
need for another burner and controls.
After the parts are pretreated and dried they are generally allowed to cool to, at
or near ambient temperature. The parts then enter the powder application booth,
complete with collection and/or powder recovery equipment. The powder
application booth serves as a containment system for over-sprayed powder.
This powder material can be collected for reuse or discarded as scrap, oven.
The parts are exposed to heat inside the cure oven for the proper length of time
and with the correct atmospheric temperature setting to allow the coating to
bond with the substrate according to the powder manufacturer's cure
recommendations.
Finally, there needs to be adequate time to allow parts to cool for off-loading
and packaging. With careful planning and proper research, the odds will be
stacked in your favor in the design of an efficient and profitable powder
application system.
