ABRASIVE RECYLING SYSTEM

ABRASIVE RECYLING SYSTEM

Model: SEMI

Mobile grit recycling module is the most useful unit for recycling the spent abrasive on open sites or at blast room. The unit is desig- ned and manufactured for transporting it at any location without dismantling the same. The mobile unit is complete with manual feed hopper, dust collector and cleaning cascade ready for use on site

A Portable Recycling system is provided to reclaim the useful abrasive from the spent abrasive. The spent abrasive is mixture of broken abrasive, dust, useful abrasive and other contaminants. The proportion of useful abrasive reclaimed depends on the initial size and type of abrasive used. In case of steel abrasive the brake-down rate is nominal, whereas expandable abrasive such as Garnet has very high rate of brake-down.

In recycling system, the spent abrasive with all the contaminants is manually swept from floor and loaded to the infeed hopper of the recycling unit.

The bucket elevator discharge the spend abrasive to a two deck vibratory wire screen mesh separator unit. Initially, the spend abrasive falling to the top deck gets screened through the coarser wire mesh separating the large size particles allowing the good abrasive and smaller sized particles to fall on the second (middle) deck . All the waste from the top deck is discharge through the refuse pipe.

An inbuilt bucket elevator elevates the spend abrasive and drops to a double deck vibratory screen separator.

Salient Features

The used abrasive on the floor will be manually swept and loaded in the hopper provided to feed the same to the Grit Recovery System. This abrasive is then transferred to the double deck vibrating screen.
A horizontal slide gate has been provided at the bottom of the feed hopper for controlling the feed rate to the vibratory screen.
The abrasive gets screened through the coarser wire mesh separating the large size particles mixed with the abrasive allowing the abrasive and smaller sized particles to fall on the second wire mesh.
The second wire mesh retains the required size of abrasives that is discharged from the middle discharge chute and is stored in a bag or storage silo. The anti blending attachment prevents the wire mesh from getting choked by the smaller or exact size of particles that of wire mesh. The finer size of abrasive passes through the second screen and then discharged through the refuse pipe to the ground. During the vibratory action the flying dust is sucked through the suction hose which is connected to the dust collector.
The air suction pipe from the vibratory deck is connected to the dust collector. The dust collector filters are cleaned by reverse pulse jet system during working of the dust collector.
A common Control Panel provides for sequential starting of the system and incorporates the necessary MCBs, indicating lamps, etc.
The unit can be transported anywhere and need 3 Phase and neutral electric connection and compressed air supply for operating.

The dust separated during recycling operation is conveyed to the dust collector through interconnecting ducts between the vibratory deck and dust extraction unit. The dust is trapped in cartridge filter and reasonably clean air is discharged to atmosphere through the blower outlet. All the fines are transferred to the refuse from the bottom discharge chute of the vibratory deck.

Vivro Screening Operational Process

Loading:

Used abrasive is manually swept and loaded into the feed hopper.

Screening:

The abrasive is screened through a coarse wire mesh, separating larger particles while allowing smaller ones to pass through to a second mesh. The required size of abrasive is retained by the second mesh and discharged into a bag or storage silo. Fine parti- cles pass through and are discarded through a refuse pipe, while dust is extracted by a suction hose connected to the dust collector.

Dust Extraction:

Dust is removed via a suction hose connected to the dust collector, which uses a reverse pulse jet system to clean the filters.

Storage:

Cleaned abrasive is discharged through the middle chute into a bag, while fine particles are discarded through the refuse pipe.

Air Filtration:

Dust is trapped in a cartridge filter, and clean air is discharged through the blower outlet.

Air Wash Operational Process:

Dust-Laden Air Entry and Initial Separation:

The process begins as dust-laden air enters through the inlet plenum of the dust collector, where heavy particles immediately settle into the hopper.

Filtration and Continuous Cleaning:

The air flows through the filter cartridges, trapping dust on the outside of the filtering media, allowing clean air to exit. The filter cartridges are automatically and continuously cleaned by high-pressure air jets, ensuring unin- terrupted operation. Dust dislodged from the filters settles into the hopper.

Abrasive Processing:

Used abrasive is placed into the abrasive hopper, then flows at a regulated rate to the elevator and into a rotary sieve. This sieve, equipped with holes of varying diameters, separates large contaminants from the abrasive.

Air Wash Cascade System:

After sieving, the abrasive passes through a cascade system where the air wash action occurs. The air wash can be adjusted to control the size of reusable abrasive particles, while dust and non-usable fine abrasive are auto- matically discharged and collected.

Cleaned Abrasive Collection:

The cleaned abrasive falls into the abrasive silo, ready for storage in large bags or blast vessels.

System Features:

The system includes additional features such as crane hooks, inspection covers, and flexible dust-exhaust ducting to ensure efficient and safe operation.
