Mini Hopper Type Blast Room

Mini Hopper Type Blast Room

Operating Principle of Mini Hopper Type Blast Room System

The job is placed inside the blast room and the blasting operation is carried out by operator manually. Used abrasive falls down into the mini hopper system from where these are transferred by air suction to reclaimer unit where the reusable abrasive goes into blast generator. From Blast generator the abrasive are transferred into the hose pipe and finally at blast nozzle for again shot blasting purpose. The unusable abrasive from media separator is collected in a bin [Buyer to arrange bin] placed below dust collector. The dust and fines from blast room is sucked and carried into Dust Collector and clean air is discharged into atmosphere, keeping the environment clean and eco-friendly.

 

The mini hopper floor is a heart of the system. It consists of a multitude of small hoppers, each having an outlet in the bottom. The hoppers which cover the entire floor area of the room are overlaid with perforated plate to from the actual working surface of the room floor. Integral with the floor hoppers is a series of ducts running along the room length. Abrasives and debris falling through the hoppers and into the floor ducts are picked up by ducts and conveyed into the reclaimer system. Mini hoppers, pick-up ducts and plenum are fabricated from 3.15mm thick steel sheet. Duct elbows are provided with abrasion resistant, replaceable wear plates.
