Clean Blast Semi Automatic Grit Recovery:
Mobile grit recovery module is the most useful unit for recovery and recycling the spent abrasive on open sites or at blast room. The unit is designed 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.
Capacity: 2 M³/hr
Overall dimensions: 2.1 M (L) x 1.4 M (W) X 2.1 M (H)
Power Requirement: 3.7 KW, 3Ph, 4 wire (3Phase + Neutral), 50 c/s, 400 V, A.C.
Compressed Air: 4 cfm at 6bar
(Screen Mesh is normally supplied in 16 B. S. suitable for maximum particle size of 0.8 mm. For other sizes, suitable screens can be provided as per the specific requirement.)
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 hosewhich 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 dustcollector 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.
