Tunnel – pass-through type shot blasting installation for the surface treatment of marble, granite and natural stones products as well as concrete and aggregate blocks to obtain a bush-hammered, flame treated, antique appearance finishing.
Each unit is provided with a steel mesh belt for the conveying of material and with a series of turbines for the propelling of metallic blast media.
Available widths: 450, 600, 800, 1000, 1200, 1500, 1800, 2200 mm; – Pass-through height : 200-400 mm; – Production speed: 1÷5 m/s.
The roughening is carried out with preset intensity by installing a variable speed drive for the turbines control in order to optimize the surface pressure of the metallic blast media. Very high productivity with very low operating cost, when compared to commonly used traditional systems. Possible simultaneous treatment of the top and side surfaces.
Here are some examples of machines made by COGEIM EUROPE. In addition to the standard range of shot blasting machines, manufactures custom systems tailored to the needs of production and handling of the products.
