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 on to the work piece by blast nozzle. The blast room contains the abrasive being shot at the work-piece, as well providing lighting and ventilation for the operator’s safety.

KHOLEE BLAST offers a variety of blast room designs and room configuarations which allow to design a blast room facility uniquely tailored to meet the economic production, safety and environmental concerns of each customer.

As each Blast Room is designed specifically on a project by project basis the possibilities for customization are endless: multiple blasters operating on one room; product access through one end or both ends of the blast room; abrasive recovery options including: sweeping pit, cross conveyor, U shape, H shape, and complete floor automatic recovery with conveyor system or scrappers or waffle floor recovery system; down draft or cross draft dust extraction.

The size of the blast room depends on:

■ The size of the work-pieces

■ Number of Blast Operators

■ Adequate working space around the job.

Blasting Media Recovery & Separation System:

All abrasive recovery systems include three basic functions:

■ Delivery the abrasive which rebounds off the work-piece to a central recovery point.

■ Transporting the abrasive from the central point to an abrasive separator.

■ Removing dust and other unwanted material from the abrasive before it enters the blast machine to re-use.

Mechanical Recovery System:

Consists of bucket elevator, abrasive separator & shots collecting system as below:

- Shots Collecting Hopper

- Screw Conveyor

- Belt Conveyor

- Scraper Conveyor

Pneumatic Recovery System:

Consists of Waffle ‘W’ Floor, Plenum, Cyclone Shots Separator & Dust Collector

Floor Design

The floor design determines the capabilities of the room, degree of labour involvement, cost of purchase & installation. Any of the following can be chosen:

■ Single Partial Floor Recovery System

■ H Shaped Partial Floor Recovery System

■ U Shaped Partial Floor Recovery System

■ Full Floor Recovery System

◆ FAQ

What types of workpieces are abrasive blast rooms suitable for?
Abrasive blast rooms are suitable for workpieces of various sizes and shapes, especially large workpieces for mass production, such as automotive parts, shipbuilding components, mechanical parts, and steel structural parts. They are widely used for cleaning the surfaces of metals, plastics, glass, and other materials.

   How to improve the working efficiency of abrasive blast rooms?
The key to improving efficiency lies in the proper selection of blasting materials, adjustment of jet air pressure, and blasting angle. Optimizing the recycling of abrasive and keeping it clean can reduce downtime. Regularly check the filtration system and ventilation devices to ensure efficient operation.

  What safety measures are required when using abrasive blast rooms?
Safety glasses, earmuffs, gloves, and dust masks must be worn during operation to avoid inhaling dust and abrasive splashes. Regularly check the electrical system and ventilation equipment to ensure the airtightness and safety of the blasting room and prevent leaks or fires.
