  1. Why will the separator be your ally to improve your operational mix?

    The separator is a key element of any shot blasting system. Usually it is located on top of the storage hopper, this is in charge of removing the contaminants out of the Operational Mix of shot, as well as controlling the size of the retained abrasive and disposing of material such as; very fine abrasive, contaminants removed from parts, etc. With the clean abrasive falls directly into the hopper.

    In this way, the efficiency of the separator becomes a crucial parameter in operating costs, as well as the adjustments that must be taken care of within it, such as the extraction of fines from the system and the air flow that passes through it.

    Most of the separators have a rotating screen to remove large contaminants and an outlet to a container to deposit all the trash.

    The design of the separator varies from machine to machine, but in all, the fundamental principle of operation is the same:

    • Extend the abrasive curtain through the separator
    • Regulate
  2. What is shot blasting or sandblasting?

    We invite you to listen to this blog through our podcast in your favorite medium


    Shot blasting, also known as abrasive blasting, is even known by some as "sandblasting" by its English term, although the latter concept refers exclusively to blasting with silica sand. It is a process where an abrasive material is propelled by means of air, water or centrifugal force against a surface.

    This method is used to clean, strengthen or prepare surfaces.

    There are many variants in the procedure to throw the abrasive medium but the most common is to do it through a machine with wheels, which drive the abrasive against the target, that

  3. How to choose the correct abrasive for your sandblasting process?

    To understand the how well, we need to understand well what is sand blast or sandblasting? The definition of this word is understood as “sand under pressure”; however, numerous abrasives in addition to sand can be used in this operation to clean, polish or remove materials and residues from different surfaces.

    In areas of abrasives, we have 2 types commonly used:


    • Aluminum oxide
    • Steel shot
    • Silicium carbide
    • Sodium bicarbonate
    • Cut wire
    • Garnet
    • Copper slag
    • Glass pearl
    • Plastic abrasive


    • Silica sand
    • Diamonds
    • Quartz
    • Corundum


    To sandblast, we use compressed air which propels the abrasives at
