Shot Blasting Machines for Profiles, Pipes and Steel Construction - EST

CYM Materiales SA manufactures continuous flow equipment for shot blasting, welded structural shapes, profiles, bars, plates, steel strips and pipes according to the needs of each customer.

The 4 lines of equipment that we carry are the PER, CH, PER-I and EST. In the PER and CH lines the blast wheels are located at 90 degrees from the parts pass-line.

In the PER-I and EST lines, they are located at different abrasive projection angles.

The abrasive is propelled by centrifugal turbines. The number of turbines for each machine depends on the size of the parts to be blasted or the speed required.

The conveyors may be a parallel roller bed or an overhead rail conveyor that introduces the parts into the chamber continuously. The machine may be equipped with in-line painting to avoid costly secondary handling of the parts.

MAIN USES AND APPLICATIONS

Pre-shot blasting of raw material – PER-R and CH lines
- Process prior to the manufacture of welded structures
- Elimination of scale and rust, improving the processes of cutting, drilling, welding, etc.
- Reduces the level of dust in the facilities
Shot blasting of welded structures - PER-I and EST lines
- Process prior to the application of a coating (paint)
- Leaves the surface clean, free of rust and scale
- Increased surface roughness improving the anchoring of the coating to be applied

TECHNICAL DATA – STEEL CONSTRUCTION SHOTBLASTING SYSTEM - EST

RELEVANT FEATURES

They process all types of welded structures, spools and raw materials (plates, angle profiles, L, H, etc. and tubes), with high production volume and minimum operating cost.
Equipped with 8, 12 or 16 turbines, blasting the pieces at multiple angles of impact achieve a correct cleaning homogeneity in the processed parts
Using Continuous monorails hook conveyor to process parts in suspended load allow to work in line with painting processes
Homogeneity of finish in the processed pieces.

Other Equipment Used in the Steel Industry

PRESERVETION LINES – CH

Complete in-line shot blasting and painting lines for shop primer applications, thus avoiding unnecessary handling of parts with high productivity and low operating cost.
- CH-H line of horizontal passage to process raw material, plates and profiles in H and pipes
- CH-V vertical passage line for plates
Variable conveyor length with transfer option for lateral loading and unloading, optimizing the efficiency of the system.

PIPES - TUB

Equipment for external and internal shot blasting of tubes used in the manufacture of gas pipelines, oil pipelines, aqueducts and other industries.
Our wide portfolio allows shot blasting of tubes of very varied sizes and thicknesses, in diameters ranging from 12 mm to more than 3000 mm and shot blasting speeds between 1 m2/minute and 1 more than 20 m2/minute.

BLAST ROOMS

Flexible blasting process allows to process all kinds of pieces that, due to their size or complexity, cannot be processed in automatic shot blasting machines
One or more operators are inside the blast room during the blasting process using pressure blast pot to project the abrasive.
In combination with nozzle manipulators installed in the blast room, surfaces can be automatically processed.
