TRL

  • Continuous Pass-Through Wire Mesh Conveyor Style Machine Specifically Designed for the Surface Treatment of Marble, Granite and Cement Products

  • Continuously Variable Blast Wheel Speed and Pass-Through Speed

  • High Volume Air Abrasive Recovery and Cleaning System at Exit

  • Accommodates Work pieces up to 47.24 Wide x 11.8 High

  • Flat Floor Installation No Pits

The TRL series of machines is a pass through wire mesh conveyor type machine specifically designed for the surface treatment of marble, granite and cement products.  Entire surfaces of each work piece can be treated or decorative designs can be etched into work pieces with the use of stencils.  Work pieces with overall dimensions and weight not exceeding the specifications can be blasted in continuous operation.  Work pieces are placed onto a steel wire mesh conveyor and transported through the blast cabinet where overhead blast wheels are positioned to ensure that the entire work piece surface is exposed to the blast stream. 

The pass-through openings in the entry and exit vestibules are shrouded by wear resistant rubber curtains to limit the escape of stray abrasive.   The exit vestibule is fitted with a high pressure fan powered blowing system for thorough cleaning of the work pieces as well as for recovering any residual abrasive.  This machine is designed to allow for installation on a flat floor, not requiring any pits or pockets.

All OMSG shot blast machines include an integral abrasive recovery and cleaning system.  After passing through the blast wheel, the abrasive is collected, separated from the resulting dust and other contaminants, and then stored in a hopper, ready for reuse.  Collected contaminants are stored in a separate hopper for periodic disposal.   

All machines utilize replaceable highly wear resistant materials in critical locations.  All machine control systems are pre-piped and pre-wired.  All machine dust exhaust ports are pre-piped to a central collection point, ready to be connected to an external dust collector or optionally, a fully integrated dry cartridge type dust collector can be provided.
