Main features:
5.2.3 Abrasive Reclaim System
The system includes following parts: bottom scraper conveyor, bucket elevator, separator, abrasive feeding gate valve and abrasive feeding pipelines. And each part has an interlock.

Infrastructure
|
0.5-1.2 m or no foundation, low construction cost. . |
2.5-4 m deep pit, high waterproof requirements, foundation construction costs are several times higher than pneumatic recovery.
|
| 2 | Abrasive |
Abrasive sorting There is separate sand returning fan. The cyclone separator is used to sort the abrasive. The particle size can be adjusted accurately, and the dust is large.
|
There is no separate return sand blower, and the suction pipe is used for vacuuming. The particle size of the abrasive cannot be adjusted, and the air volume of the dust is not easy to be enlarged, and the sprayed abrasive is not uniform;
|
| 3 | The over-all layout |
beautiful, the floor space is small, and the installation is convenient. Since all the equipment are connected by pipes, the installation positions of each system can be installed at will according to the site conditions.
|
Each transmission system needs to be closely coordinated, it is impossible to change the installation position, the floor space is large, and the maintenance is inconvenient.
|
| 4 | Abrasive accumulation in the sand return system Abrasives |
remaining in the sand return system and fewer Abrasives
|
remaining in the sand return system, such as screw conveyors, bucket elevators and other equipment will accumulate a large amount of abrasive
|
| 5 | Occupational safety and environmental protection |
The overall sand-absorbing and dust-absorbing floor, the wind flow from top to bottom, the dust suppression environment, dust content, visibility, dust emission are better than the national standard.
|
Because the underground material needs to be installed with sand conveying equipment, the suction method is generally sucking up. The wind or side suction forms a dusty environment with high dust content, low visibility, and poor working environment.

5.2.3.1 Bottom Scraper Conveyor
l Multichannel sand scrapers made by PU material and steel plates at the bottom of inside sand blasting room, which pushes abrasives to the back of room through vertical reciprocating motion, into the horizontal screw conveyor through Hopper. The horizontal screw conveyor delivers abrasives to outer bucket elevator and into sand blasting room to finish circulation through separator and abrasives screening.
l The scraper conveyor adopts scraping collector driven by air cylinder or motor to reciprocate, which can save deep trench, reduce civil engineering costs, easy maintenance and stable performance.
l Cylinder driving can effectively reduce running noise and save costs.
l High reliability of motor driving, without effect of lack of air source. It can be equipped with PLC to control speed and frequency of scraper reciprocating motion.
