The layouts of complete Blast Room System are always different from plant to plant, every blast room must be designed independently depending upon the customer’s requirement. National Enterprises offers variety of Blast Room designs and system configurations which allow us to design a blast room facility uniquely tailored to meet the economic production, safety & environmental concerns of each customers. Blast room equipment is used in a wide variety of industries that require surface preparation prior to the application of a protective coating. The surface of the work piece is cleaned by a mixture of abrasive and high pressure compressed air being directed at the work piece by blast nozzle. The blast room contains the abrasive being shot at the work piece, as well providing lighting & ventilation for the operator's safety. Enclosure :The modular blast room is specially ventilated and illuminated for enclosed abrasive blasting, and is a fully sealed, dust tight, all steel structure. The components are prefabricated for simple bolt-together erection, with little or no job site welding required. The enclosure stands by it’s own structural support without connections to the surrounding facilities. Internally, the enclosure has no areas, other than the floor, where airborne media or dust may be captured. The size of the enclosure depends on : The size of the job Number of operators Adequate working space around the job. Single Screw Partial Reclaim System : A single screw partial reclaim system is the most economical floor design available. The system contains the major components heavy-duty screw, belt and bucket elevator, air-wash separator, perforated storage hopper with a caged man ladder and handrail. This is a basic "automatic" reclaim package that can be expanded to and "H", "U" or full floor reclaim system. It best suited for low to medium productive levels. H Shaped Partial Reclaim System : The "H" shaped partial reclaim system adds two longitudinal screw assemblies along each side wall of the blast room. The position of the screw assemblies allows the abrasive delivered from the blasting nozzle, which is either blown or rebounded off the work piece, to strike the side walls and fall into the screws, automatically reclaiming approx. 60 - 90% of the blast media. This system is best suited for medium to high production. U Shaped Partial Reclaim System : The "U" shaped partial reclaim system adds two longitudinal metered screw assemblies along each side wall of the blast room. The position of the screw assemblies allows automatically reclaiming approx. 60 - 90% of the blast media. This floor design is typically utilized in a "flow-through" room configuration where heavy work pieces and/or material handling devices can drive into the room and position the work piece on the steel covered concrete floor located between the longitudinal screws. This system is best suited for medium to high production. Full Floor Reclaim System : The full floor reclaim system utilizes multiple screw assemblies to create a fully automatic abrasive reclaim system, where 100% of the blast media is returned to the separator system during the blasting operation. This system is best suited for high production requirements. Recovery Systems :All abrasive recovery system include three basic functions : Delivering the abrasive which rebounds off the workpiece too a central recovery point. Transporting the abrasive from that central point to an abrasive cleaner. Removing dust, fines and other unwanted material from the abrasive before it enters the blast machine to re-use. Mechanical Recovery : Consists of Bucket Elevator, Abrasive Cleaner & Screw Conveyor SystemPneumatic Recovery : Pneumatic Recovery works best with light weight media, such as agricultural, plastic, glass bead or aluminium oxide. The "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 respiratory 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.

Shot Blasting is the process of cleaning a surface such as iron, steel, cast-iron parts, forgings, rusted pipes, iron bars, engine and automotive parts by blasting abrasive material such as steel shots or steel grits at very high velocity utilizing the centrifugal force generated by high speed rotating disk in a shot blasting machine.Shot blasting is also used to alter the mechanical properties or various components, increasing resistance to fatigue for springs, gears, etc. Compared to sandblasting process shot blasting does not produces large amounts of dust and is much more environment friendly. A shot blasting machine is like a closed chamber so the dust particles generated at the time of blasting process remain inside the chamber and does not pollute the environment. Shot Blasting Machine is used in almost every industry that works with metal components: Ship Building and Ship Yards Aerospace and Aircraft Maintenance Iron Castings and Other Metal Foundry Forgings Rail Car and Bus Painting Alloy Wheels Cleaning Shot blasting is also used to clean floors, roads and outer walls at construction sites. Other applications of shot blasting include cleaning of under water pipes and tanks before coating or re-coating them to prevent corrosion. When we talk about shot blasting then it is important to remember that we are referring to a shot blasting machine which works by directly converting electric motor energy into kinetic abrasive energy by rotating a centrifugal wheel at a minimum of 60 kg per minute which can go upto 1200 kg per minute. With such high amounts of accelerated abrasive a shot blasting machine is used to derust, descal, deburr, desand or clean large metal parts or surfaces that cannot be cleaned effectively through other traditional or manual processes. Difference between shot blasting and sandblasting is simple to understand. In sandblasting compressed air is used to propel the abrasive towards the surface that needs to be cleaned and in shot blasting a centrifugal wheel is used to propel the abrasive toward the surface using an electric motor.   Advantages of Shot Blasting: Shot Blasting is inexpensive and time saving and also abrasive material is reusable which makes shot blasting extremely affordable. Cleans and smoothens a metal surface without any damage to the surface. Economical to use and environment friendly as it does not produces very less amounts of dust compared to sandblasting. Prepares a surface for coating or re-coating applications effectively. Smoothens a rough surface and roughens a smooth surface effectively. Flexibility of using various types of abrasive materials that can be used in a shot blasting machine depending on the surface that needs to be cleaned such as glass beads, steel shots, steel grit etc. makes shot blasting the most preferred method of cleaning or preparing different metal surfaces and components.   Factors that affect the Shot Blasting process and its effectiveness: Condition of the surface or the metal part that needs to be cleaned and the contaminants deposited on the surface that need to be removed. Velocity and the abrasive used to treat the surface. Working Condition of the shot blasting machine. Size of the abrasive. Hardness of the abrasive material. Level of humidity and temperature as exposure of metal surface to the environment makes it susceptible to oxidation.
