BLAST ROOM RECOVERY SYSTEM

All abrasive recovery system include three basic functions:

Mechanical Recovery

Consists of Bucket Elevator, Abrasive Cleaner & Screw Conveyor System

Pneumatic Recovery

Pneumatic Recovery works best with light weight media, such as agricultural, plastic, glass bead or aluminum oxide. In MEC SHOT "W" Section pneumatic recovery system, dust and media fall through funnel shaped holes into channels beneath the floor. High velocity air carries this media and dust to the reclaimer.

Because there are no moving parts, pneumatic floors are simple to operate and maintain. Pneumatic recovery requires the use of a reclaimer - a type of cyclone separator - to separate blast media from the dust, debris and fines.

Scrapper Floor Recovery

One of the mechanical recovery systems from blast room floor where the abrasive is pushed forward by pushers in to the plenum/screw hopper for reuse.

The scraper floor is designed to automatically recover spent abrasive and contamination back to a bucket elevator. The scraper floor consists of a series of pivoting blades fitted into a movable frame. The scraper move back and forth by a pneumatic cylinder. The blades ride up and over the media on the backwards stroke, pushing the abrasive along on the forward stroke. The media is then transported to the abrasive cleaning unit. The advantage of the scraper floor system is its low profile design which reduces or, if floor mounted, eliminates any foundation costs. The system is designed for low maintenance and does not require any tools to remove the blades from the modules for inspection or repair.

Air Ejector Recovery System

Air Ejector type Recovery is a low cost abrasive recovery system in which abrasive is swept manually in a corner & fed in the feed hopper. From the feed hopper air-operated, air-injector by a reciperatory pipe forces the abrasive into separator drum through elevator pipe. Fine dust from the abrasive is separated in and usable media with fine particles of abrasive passed through fine screen separator. In fine screen separator the fine abrasive particle get filtered out and usable media transferred into pressure tank for reuse.

Vacuum Recovery System

The MEC SHOT Vacuum Abrasive Recovery System meet the high demand from the industry due to its efficiency, reliability, ease to operate and giving excellent value for money.

The Abrasive & dust Laden air is carried to the Recovery System by Suction effect created by Exhaust Fan of Turbo Pump. Due to suction effect, the heavy particles are separated & collected in Abrasive Hopper. The abrasive get transferred in blasting machine for reuse. The fine particles & dust laden air is further carried to Dust Collector System, where the fine particles get trapped in Dust Element & clean air is let out in atmosphere thus keeping the environment eco friendly.
