CYM Materiales SA manufactures shot blasting machines for continuous in-line descaling for steel wire industry ensuring high productivity with a low operating cost and a process that does not pollute the environment.

In-line BAR machines are designed for descaling wire rods or bars and can process in single-strand or multi-strand at the same time with high throughput speeds (more than 250 m / min.).

BAR machines also used for blasting steel billets to remove mill scale of the surface to improve the visibility prior to the crack detection process According to the model, the machines are equipped with between one (1) and four (4) turbines that together with abrasive concentrators ensure a correct coverage in the processed parts to cater to a varied range of operating requirements.

Blasting machine are complemented with pay-offfor wire rod when the equipment is integrated with drawing lines and with external roller conveyors with automatic loading and unloading systems to process bars or billets.

TECHNICAL DATA – SHOT BLASTING FOR WIRE ROD, BAR & BILLETS - BAR

MECHANICAL DESCALER ADVANTAGES

• Eliminate environmental pollution problems
• Do not need facilities for the regeneration or post treatment of waste material such as those required for the treatment of chemical effluents and toxic fumes
• When the machine is operated properly they do not cause any health problems or damages to the plant as those caused by the steam released from the chemical descaling process
• Lower production costs
• Automatic shot blasting process does not require skilled labor.

OTHER MACHINES USED IN THE WIRE DRAWING INDUSTRY

COIL SHOT BLASTING MACHINE

•  The COIL shot blasting machine has been designed to process wire rods of up to 3000 kilos of weight at a time ranging from 7 to 20 minutes depending on the type of steel and diameters of wire to be treated.
• Two models of machines available, COIL4 and COIL5 with 4m and 5m mandrel and 6 and 8 turbines, respectively, ensure optimum coverage in the coil of processed wires.
• According to customer requirements, COIL equipment can have one or two mandrel loading doors. The double door machine minimizes downtime and optimizes the process.
