A cost-effective and efficient system available in multiple floor configurations.
The PARS2000 Pneumatic Abrasive Recovery System uses duct work and a vacuum system to efficiently collect and convey used abrasive media to a cyclonic separator, which separates reusable blast media from dust and foreign particulate matters.
It is an efficient and inexpensive solution for recovering used abrasive with minimal effort from the operator. It offers various floor hopper layouts and allows for longer hopper length compared to MSW1200. It can handle all major light-to-heavy abrasives available on the market except steel grit GH-36 or bigger and steel shot S-230.
This system is recommended for 8-hours-a-day blasting operations and is suitable for a large variety of applications. It provides a cost-effective alternative to the Mechanical Abrasive Recovery System when budget is limited.
The key advantages of a pneumatic abrasive recovery system:
The recovery rate capacity is 2,000 lb/hr.
After contact with work pieces, abrasive media falls on the floor and mixes with the blasting process by-products – paint chips, rust, scale, shattered blast media, solid debris, etc. In a pneumatic abrasive recovery system, the dirty media mix is sucked through a ducting vacuum system all the way to the cyclonic separator where particles are sorted out based on their specific density, through vortex separation.
The suction motion and power is generated from an impeller powered by an electric motor located on a dust collector next to the blast pot and cyclonic separator assembly. The dirty media mix is then drafted into the system from floor hoppers excavated in the floor or located above-ground.
Pneumatic abrasive recovery systems are very economical and efficient for most types of media. However, they have certain limitations in terms of floor layout and are not suitable for some applications. Here’s why.
Below each floor hopper, the dirty media mix is sucked through a 6-inch urethane vent duct to the cyclonic media separator. Since the suction power is determined by an impeller located on top of the reclaiming system’s dust collector, the length and possible configurations of the floor hoppers are limited by the suction power generated, resulting in lower floor coverage compared to mechanical recovery systems.
Common pneumatic system floor layouts may vary from a 4-foot corner shoot to a 40-foot long floor recovery pit, depending on the application and type of media.
The cyclonic separator is the heart of the pneumatic media recycling system. Its function is to sort out dust and fine particulates from the dirty media mix collected on the floor after a blasting operation, allowing only blast media still in good shape to return to the blast machine. For that reason, it connects to a dust collector to capture dust and fine particles.
A high-speed rotating motion is created when the airflow travels through the cylindrical-shaped housing of the cyclonic separator. To avoid premature wear on panels caused by friction with the dirty media mix, an optional rubber lining can be added to protect the interior walls of the cyclonic separator.
When leaving the cyclonic separator, the dirty media mix has two possible exits:
The cyclone flow is adjustable from a rubber band located around the cyclonic separator in order to address a wide variety of media types and applications. A set of holes partially covered by the rubber band allows air into the cyclonic separator, which accelerates the vortex using the Venturi principle.
The more air you let into the entrance of the cyclone, the more aggressive the vortex motion will be, drafting up particulates with higher density. Oppositely, covering the holes partially or completely will allow less air into the system, producing a less aggressive vortex.
An improperly configured abrasive recovery system will either exhaust the entire dirty media mix – including good media – to the dust collector when too much air is allowed into the vortex, or rather the opposite, a vortex that is too weak will allow light particulate matters to fall down into the blast pot, which will negatively affect the impact of the media stream onto the workpiece and produce too much dust during operations.
However, you do not have to worry about this. The calibration of the recovery system only needs to be set once, and this is part of the blast machine startup procedures that will be handled by our qualified technicians.
This abrasive recovery system is delivered with a PARS2000 Cartridge Dust Collector which has an overall filter area of 200 sq. ft. and is equipped with a 10 hp / 800 cfm engine. Cartridge media can capture 99.9% of particles down to 1 µm, and an optional H.E.P.A. filter can be added to the exhaust to capture 99.98% of particulates down to 0.3 µm.
Its main function is to collect debris and foreign particulate matter sorted out by the cyclonic separator. It also generates the vacuum motion and power of the whole recovery system from an impeller powered by an electric engine mounted on its head for optimal efficiency.
This dust collector operates independently from the blast booth’s main dust collector, which is designed to draft away and collect airborne contaminants floating in the air during blasting operations.
The recovery system dust collector has a reinforced frame designed to resist a very high air suction demand. This dust collector is extremely sturdy and durable, and requires minimal supervision and maintenance from the operator. It is delivered with a standard vertical muffler, or an optional horizontal muffler when space is not available.
The cyclonic separator is mounted on top of the pressure blaster assembly, right onto the storage hopper.
The storage hopper ranges from 3.5 to 100 cu. ft., depending on the available ceiling height space, and is used as a temporary storage unit for abrasive media while it exists in the cyclonic separator. When the pot runs empty, it must simply be depressurized to let the plunger fall, in order to refill it with media waiting in the storage hopper.
Kresco offers various types of recovery floors adapted according to your available production space and budget. In surface or excavated installations, dimensions can vary from 4 feet in length in compact facilities to over 40 feet for high-output industrial facilities. The configurations are practically infinite!
Shallow and space saving over-floor design, is easy to install and requires limited maintenance. 17” floor excavation is sufficient for existing floors. System can also be installed on concrete floor or on any other permanent or temporary floor.
We manufacture a complete line of Recovery Systems to accommodate sandblasting facilities constraints, and these systems are compatible with our equipment, other manufacturers’ equipment and even with self-made facilities. Good recovery systems respect the 3R fundamentals: Reduce, Reuse and Recycle the abrasive.
Recycling abrasives results in substantial savings in abrasive consumption while protecting the environment from harmful sandblast dust. Because of its fragile molecular structure, non-recyclable media deteriorates quickly while generating harmful residual dust and substantially reducing operator visibility.
Although cost of steel-shot abrasive is about 10 times higher than non-recyclable media, steel shot can be recycled and used up to 100 times, compared to only once with standard media.
