BLASTING ROOMS

Sandblasting is the most efficient

technology for cleaning and other

surface treatments. It is also a hard

and environmentally unfriendly work.

Till nowadays blast work was mainly

done in open spaces, thus polluting the

environment with dust and old paint

residues containing heavy metals and

poisonous chemicals. It is also a rather

very loud procedure. Meantimes strong

environment protection regulations

oblige everybody to work according to

environment protection standards and

to particular safety regulations

regarding blast work.

Our know-how and more than 45 years of experience can assist you in solving any of your

problems with pollution or with personal protection equipment.

The sole law-conformant solution for the cleaning of large objects is the blasting in closed systems

with recycling and filtration – ECOLOGICAL BLAST ROOMS.

Our PNEUMOFLEX recovery system was developed for light abrasive materials and is used

exclusively for the recovery and the recycling of glass beads, ceramic beads, plastic granulates and

exceptionally (occasionally) electro-corindon of very fine grain size or similar light abrasives used for

blasting.

For the recovery of heavier abrasives (cast steel shot or grit, corindon or slag abrasives of big grain

sizes) from the blastroom floor we recommend our scraper recovery system type GUMIFLEX.

Scraping of abrasives on the floor can be partial or total, the drive of the system is usually electric but

can also be pneumatic. The scraper elements on the floor automatically feed an elevator for vertical

transport of the abrasive, which is then continuously cleaned in a separator and deposited for a new

blast cycle in a silo above the pressure blast pot. Depending on the size of the blast room, there can

be installed one or two pressure blast pots.

The choice of the abrasive material depends on type and material of the surface to be blasted, on the

required end result (quality) and on procedures following the blast operation (painting, coating,

galvanization, finishing to look like INOX,etc.)

Usually such choice of abrasives is done by our technicians, based on their experience, or blasting

tests are done first, either on site or in our laboratory, using various materials and abrasives.

SCRAPER RECOVERY OF ABRASIVES – GUMIFLEX, Producer: FerroECOBlast

In blast rooms are usually installed a few scraper elements, covered by steel grids of different load

capacities.

Scrapers are installed inside technological pit and each element has its own drive, pneumatic or

electric. The function of the scraper elements is automatically controlled by the electric control panel

that also signals stoppages or other malfunctions of scrapers, elevator and other electric

components.

DRAWING:

Designing and manufacturing these

equipments by our own, we can grant

you a 3 years warranty, and we also

guarantee for a continuous operation of

the system, for a perfect cleaning of the

abrasive recovered, and for long lifetime

of the system.

With different types of scrapers and

inventions we can meet all customer’s

requirements.

Thanks to long time

experiences and numerous

executed projects all round

Europe, we can adjust to

various sizes of blast rooms.

Basic pit is shallow and in some

cases it is possible to install on

flat (?level?) surface without

basic pit.

Every manufactured part is

carefully assembled in our

production line and tested under

heavy conditions.

Quality is at the end guaranteed

with three year warranty.

ABRASIVES RECYCLING SYSTEM

Following the scraper elements, this is the

second most important system of a blast room.

It is assembled with the elevator that lifts the

abrasive to a certain height where it is

separated and cleaned, staying in closed

system. After that there is mechanical cleaner

that removes dust from abrasive by blowing

through air curtain and with built in separation

system keeps 100% quality abrasive in

circulation.

BLAST SYSTEM

That is the most important component of the

whole assembly.

We produce and supply these in different sizes

and capacities. A lot of blast room details

depend on the choice of the blast system. i.e.

the size of the silo in which the abrasive is

stored above the pressure pot.

Further details about blast systems and

personal protection equipment can be found in

our special brochures.

Direction of airflow is important and so

is the right choice of type of filtering

system.

Usually, dry filtering systems with filter

cartridges and automatic “pulse-jet”

cartridge cleaning are used. For better

working conditions and save of energy

in winter we recommend to recycle a

part of the clean air from the filter back

into the blast room, the recycling rate

being adjustable.

The type of the filter unit depends on

the blast room size, the type of abrasive

used, and the anticipated time of

continuous blasting.

For each specific case the filter unit size

and performance has to be calculated

separately and cannot be based on

previously executed projects.

CONTROL BOX

The electric control panel in an industrial, dustproof version can be of standalone type or fixed on

the wall with top or bottom cable inlet and outlet. It contains all safety, control and signaling

switches necessary to operate all components of the blast equipment. The working state of all

components can be displayed on a scheme with light indicators on the control panel front side,

showing the function or the stoppage and any other malfunction for component individually.

There are rules and restrictions regarding working conditions and safety equipment in blast

rooms.

For blast rooms like for any other closed working space, special standards apply, defining the

lightening necessary to operate, the emergency lights and other signals to be installed. That is

why we recommend to have the whole project, including the electro installation be carried out

by a specialized, professional staff!

It is important that workers, even under hardest

working conditions, have everything under

control. Being protected with leather suits and

ventilated protection helmets, their mobility is

restricted and every safety regulations therefore

have to be strictly followed.

- Working with pressure blast systems without

remote control is forbidden and can have major

consequences

- The working areas must always be clean

and floor covered with grids, so that the worker

does not slip

- Ventilation and suction, together with the

blastroom lighting must be intensive enough to

leave perfect visibility onto the surface to be

blasted at any time.

Some pictures of blastrooms, which were built in

accordance to all today existing standards and

regulations in Western Europe. All built-in

components have the CE-certificate.

WORKING AND AUXILIARY AREA

That blastroom is divided by PVC door curtain

in a working and an auxiliary area. The floor of

the basic working area is completely covered

with grids, underneath are the scraper

elements, and the walls are fitted with rubber

protection. In this area most of the blast work

is done. In case of bigger and longer parts the

auxiliary area is also used, being mainly

intended for preparation work before blasting.

Also separated from the working area, by a

wall in sandwich construction with integrated

service door, is – on the opposite side – the

machinery room, where are installed the

elevator with separator, the blast system with

silo, and the drive units for all longitudinal

scraper elements. It might also be used for the

storage of abrasives, spares, and the personal

protection equipments of the operators, as well

as for service purposes.
