The purpose of the technical description below is to identify the main components of effective equipment for recycling garnet abrasives. Several recycling rules are also covered that are critical to understanding when recycling garnet (or any non-ferrous abrasive). Finally, it explains . how to monitor the effectiveness of a recycling operation.
Key Components of an Effective Garnet Recycling Team
The most important component of any recycling system is the method used to separate and
classify the used abrasive. Experience has shown that systems using a gravity air scrubbing .The system, such as grit and garnet vaccum recovery unit in UAE, is very effective at recycling garnet. A coarse particle screen under the air wash has proven helpful in removing additional contaminants and improving the cleanliness level of the recycled garnet. Other important components of a typical recycling system include a loading hopper, a bucket elevator, an integrated storage hopper (for storing recycled abrasive), and a reverse pulse cartridge dust collector. Depending on the application, a cleanliness level of 90-95% should be possible.
Overview: Recycling garnet efficiently
Ensuring that recycled abrasive (known as the ”correct abrasive mix”) is clean and contains abrasive particles with the proper size range involve two basic operations: removing oversize or undersized contaminants and adding fresh abrasive filler. To efficiently accomplish this, both the new and blasted abrasive makeup garnet must be kept dry. Correct recycling of the blasted abrasive (used garnet) is achieved by air wash separation. A loading hopper screen removes large contaminants such as paint chips, rust, welding rods, and debris from the job site. An air wash separator unit, running in conjunction with a dirt collector, eliminates undesirable satisfactory garnet abrasive particles.
The ”Right Mix of Garnet ”
A good working mix contains a well-balanced distribution of large, medium, and small abrasive particles. Large particles perform the main task of loosening coarse and heavy contaminants (thick or thick coatings). Small particles provide the coverage (blast speed) necessary for the efficient removal of lighter coatings, scale, and rust. Smaller particles also perform the important task of thoroughly cleaning and cleaning valleys in pre-polished surfaces and ensure that any slight deviations or pitting in the surface are cleaned to meet the surface standards of SA 2.5 or SA3 as required. required for the project.
Establishing a suitable range of particles in the working mix depends on the individual project. For blasting applications that remove light rust, mill scale, primers, and thinner coatings, the work mix can be expanded to include 100 or even 120 mesh garnet particles.
Adjustment of the recycling equipment
The ProFlo and UltraFlo abrasive recycling systems use the correct size air wash separator because they can be precisely adjusted to remove the fines from the dirty garnet abrasive in the grit recycling machine UAE . It is important to use a system with a properly designed air wash system.A nicely-designed air wash . A separator works lot like a vacuum purifier. AnA excellent curtain of grimy garnet abrasive slides Beneath a swinging baffle and then passes thru the air wash. The airflow (or suction) . Created by way of the dust collector pushes fines and airborne dust into the dirt collector. Heavier fines . Are also removed by using a decrease parting lip. It is critical to do away with as many fines as feasible . For the duration of each recycling operation. extra fines can reduce productivity, create undesirable dust throughout blast application, lessen the visibility of blast operators, and severely reduce the profile of the blastedt floor.
